Keto Baking for Beginners: What to Buy and How to Use It
Keto baking swaps wheat flour and sugar for low-carb ingredients: ground almonds as the base, a sweetener such as an erythritol and stevia blend, fibres like oat fibre or psyllium for structure, and a binder like xanthan gum (usually ¼ to 1 teaspoon). Start with a mix or a simple biscuit while you get used to how they behave.

Keto baking can feel like learning to bake all over again. The ingredients have unfamiliar names, recipes call for a teaspoon of something you've never heard of, and your first batch of biscuits can come out darker, softer or more crumbly than you expected. The good news is that there are only a handful of new ingredients to get to know. Once you understand what each one does, low carb baking becomes as predictable as the baking you grew up with.
This guide is for complete beginners. It explains how keto baking differs from normal baking, what to keep in your cupboard and how much of each ingredient to use, then suggests five easy first bakes and the fixes for the most common beginner mistakes.
How keto baking differs from normal baking
In ordinary baking, wheat flour and sugar do most of the work. Flour gives bulk, and the gluten in it forms a stretchy network that traps air and holds a cake or loaf together. Sugar sweetens, but it also browns, keeps sponges moist and helps cookies spread. Keto baking replaces both, so a few things change.
Browning
Ground almonds, the base of most keto bakes, brown faster than wheat flour. Edges can turn dark before the middle is cooked. Many keto recipes bake at a slightly lower temperature for that reason. Our keto shortbread, for example, bakes at 160°C (140°C fan), with a tip to cover it loosely with foil if the edges colour too quickly. Erythritol, on the other hand, doesn't caramelise like sugar, so the bake itself can look paler than you expect. Go by the recipe's timing and a skewer test rather than colour alone.
Moisture
Sugar holds on to water, which is part of what keeps a sponge soft. Bakes made with erythritol can be a little drier and firmer, especially the next day. Fibres such as oat fibre and psyllium soak up liquid too, so keto recipes often use more eggs, butter or liquid than you'd expect. Weigh your ingredients, avoid overbaking and store bakes in an airtight tin.
Binding
There's no gluten in ground almonds, coconut flour or fibre powders, so something else has to hold the bake together. That's the job of a binder: usually a small amount of xanthan gum, or psyllium husk powder in breads, plus eggs. Without one, cakes crumble and doughs fall apart when you roll them.
Yeast can't feed on erythritol. If you want to bake a yeasted loaf, use a recipe written for low-carb bread rather than swapping keto ingredients into a standard bread recipe.
The keto baking cupboard
You don't need everything at once. A sweetener, a binder and a bag of ground almonds will get you through most beginner recipes. Here's what each of the common keto ingredients does and how much to use. The amounts come from our product pages and recipe cards. Where a recipe gives its own amount, follow the recipe.
| Ingredient | What it does | How much to use | Groovy Keto product |
|---|---|---|---|
| Granulated sweetener | Sweetens and adds bulk in place of caster or granulated sugar | Same weight as the sugar (1:1) | Granulated Erythritol & Stevia Blend |
| Icing sugar swap | A fine powder that dissolves smoothly in icing and buttercream | Same weight as the icing sugar (1:1) | Powdered Erythritol & Stevia Blend |
| Brown sugar swap | Golden colour and a caramel flavour for cookies, flapjacks and spiced bakes | Same amount as the brown sugar (1:1) | Brown Erythritol & Stevia Blend |
| Oat fibre | A light, fluffy baking fibre that gives a lighter texture and a crisper snap to biscuits | Follow your recipe. Our shortbread uses 15g with 200g ground almonds | Oat Fibre |
| Bamboo fibre | A neutral-tasting fibre used for texture in keto bread loaves, muffins and pancakes | Follow your recipe | Bamboo Fibre |
| Psyllium husk powder | Forms a gel with water, helping breads, rolls, wraps and pizza bases hold together | About 5% of the flour weight (roughly 6g per 125g flour), or 2 tsp in place of 1 tsp xanthan gum | Psyllium Husk Powder |
| Xanthan gum | Binds cakes, biscuits and breads and gives doughs more stretch | Most bakes use ¼ to 1 tsp. Mix it into the dry ingredients first | Xanthan Gum |
| Chocolate chips | Dark chocolate (minimum 64% cocoa) sweetened with erythritol and stevia, for cookies, brownies and muffins | 0.6g net carbs per serving. Fold into doughs and batters, or melt | Keto Sugar Free Chocolate Chips |
Amounts and figures are taken from each product page and our recipe cards. Net carbs on our chocolate chips are total carbohydrate minus polyols. Psyllium is light and fluffy, so spoon measures vary; weigh it for bread. Ground almonds aren't a Groovy Keto product, but you'll find them in most supermarkets.
Ready to stock up? You'll find our sweeteners, fibres, binders and chocolate chips in our keto ingredients range.
Ground almonds are tree nuts, and our Brownie, Cookie and Vanilla Cake Mixes all contain almonds (the Vanilla Cake Mix also contains milk). Our xanthan gum, psyllium husk powder and brown blend are packed in a facility where there may be traces of gluten, nuts, cereals, milk and eggs. If you're baking for someone with an allergy, check the current pack label first.
Swapping sugar
The simplest rule is to replace like with like. Use a granulated erythritol and stevia blend wherever a recipe asks for caster or granulated sugar, a powdered blend for icing sugar, and a brown blend for soft brown sugar. Our three blends are all designed to swap 1:1, so you can keep the recipe's quantities as they are.
Erythritol on its own is less sweet than sugar, which is why it's blended with a little stevia. It can also leave a slight cooling taste in uncooked recipes like buttercream, and vanilla, cocoa, spices or citrus help balance that. Our guide to sugar substitutes for baking covers every common swap in detail, including how to make your own icing sugar substitute. If you're choosing between sweeteners, our comparison of erythritol vs stevia for baking explains how each one behaves.
Binding and structure: xanthan gum vs psyllium
Most keto bakes need a little help holding together, and the two binders you'll see most often are xanthan gum and psyllium husk powder. They do a similar job in different ways.
- Xanthan gum is very concentrated, so you only need a little: most bakes use between ¼ and 1 teaspoon. It suits cakes, muffins, biscuits and pastry. Whisk it into the dry ingredients first so it spreads evenly and doesn't form lumps.
- Psyllium husk powder forms a gel when it meets water. It's the better choice for bread, rolls, wraps and pizza bases, where you want a dough you can shape and slice. Use about 5% of the flour weight, add a little extra liquid and let the dough rest for about 10 minutes so the psyllium can absorb it.
You can swap one for the other at roughly 2 teaspoons of psyllium husk powder for every 1 teaspoon of xanthan gum. Our guide to using psyllium husk instead of xanthan gum explains when the swap works best and when it doesn't.
Five easy first bakes
The best way to learn is to start with something simple. These five bakes go from "add an egg and butter" to a short from-scratch recipe, so you can build up your confidence one batch at a time.
1. Keto brownies (from a mix)
Our Keto Chocolate Brownie Mix is the easiest starting point. Mix it with 130g melted butter and 2 eggs, spread it into an 8-inch (20cm) square tin and bake at 180°C for 15–20 minutes, until a knife comes out clean. It makes around 12 brownies, each with 0.8g net carbs. Let them cool before slicing, as they firm up as they cool.
2. Keto cookies (from a mix)
The Groovy Keto Cookie Mix needs just an egg and butter. Shape the dough into 14 small balls, flatten them and bake at 180°C for 10–12 minutes. Each cookie has 1.5g net carbs. For chocolate chip cookies, fold a handful of chocolate chips into the dough before shaping.
3. Keto vanilla cake or cupcakes (from a mix)
Our Keto Vanilla Cake Mix takes 3 eggs and butter. Pour it into a lined tin and bake at 175°C for 20–25 minutes, or spoon it into cupcake cases instead. Each slice has 1g net carbs, including the eggs and butter. Top it with a buttercream made with a powdered sweetener for a birthday-style bake.
4. Keto gingerbread biscuits
Our keto gingerbread biscuits recipe is a good first rolled biscuit. It uses a 255g pack of our Keto Gingerbread Mix, one large egg and 80g melted butter. You chill the dough, roll it between baking paper, cut out gingerbread men and pipe on a simple icing. A batch of 14 takes 57 minutes, including chilling, and each iced biscuit has 1.0g net carbs.
5. Keto shortbread (from scratch)
When you're ready to bake from scratch, try our keto shortbread. It uses ground almonds, a little oat fibre, a powdered erythritol-based sweetener, butter and ½ teaspoon of xanthan gum, so it's a gentle introduction to the keto baking cupboard. The dough is pressed into a tin, chilled for 20 minutes and baked low and slow. It makes 16 fingers, each with 0.9g net carbs. The recipe uses our Powdered Monk Fruit and Erythritol Sweetener.
You'll find our brownie, cookie and cake mixes, and many more, in our keto baking mixes range. Free delivery is on orders over £30.
Common beginner mistakes and how to fix them
Almost every keto baker runs into the same few problems at the start. Here's why they happen and what to do differently next time.
| Problem | Why it happens | The fix |
|---|---|---|
| Edges burnt, middle underdone | Ground almonds brown faster than wheat flour | Bake on the middle shelf, check a few minutes early and cover loosely with foil once the edges are golden. Many keto recipes bake at a lower temperature, so follow the recipe rather than a standard one. |
| Crumbly cakes and biscuits | No gluten, too little binder or the bake was cut while warm | Add the binder the recipe asks for, such as ¼ to 1 tsp xanthan gum. Leave biscuits on the tray until firm, as low-carb bakes are fragile when hot. |
| Grainy icing | Granulated sweetener doesn't dissolve in a small amount of liquid | Use a powdered sweetener and sieve it first. Ice bakes close to serving, as erythritol can recrystallise as it dries. |
| Dry or dense sponge | Fibres and coconut flour soak up liquid, and erythritol holds less moisture than sugar | Weigh ingredients rather than using cups, don't swap flours without adjusting the liquid, and take the cake out as soon as a skewer comes out clean. |
| Dough falls apart when rolled | Almond dough is soft and has no gluten | Chill it for 20 minutes and roll it between two sheets of baking paper. |
| Cookies don't spread | Erythritol-based doughs spread less than sugar doughs | Flatten the dough balls before baking if you want a thinner cookie. |
Tips for keto baking beginners
Key takeaways
- Follow keto recipes exactly at first. Low-carb ingredients aren't interchangeable with wheat flour, so start with keto baking recipes written for them before you experiment.
- Weigh, don't guess. Sweeteners, fibres and flours vary in density, so use scales wherever a recipe gives grams.
- Keep binders small. A little xanthan gum goes a long way. Too much gives a gummy texture.
- Cool before cutting. Keto bakes firm up as they cool, so give brownies, shortbread and biscuits time on the tray.
- Count the carbs. Bakes with a gram or so of net carbs each still add up, so plan them into your daily carbs like any other food.
Frequently asked questions
What do you use instead of flour in keto baking?
Most keto recipes use ground almonds instead of flour, often with a little coconut flour or a baking fibre such as oat fibre or bamboo fibre, plus a binder like xanthan gum. These ingredients behave differently from wheat flour, so don't swap them 1:1 in a normal recipe. Follow a recipe written for low-carb ingredients.
Can you use normal baking powder on keto?
Yes, in the small amounts most recipes use. Baking powder usually contains a starch filler, so it adds a little carbohydrate, but a teaspoon is spread across a whole batch. Some baking powders contain wheat flour, so check the label if you're avoiding gluten. Our baking mixes already include a raising agent, so you don't need to add any.
Why do keto bakes brown so quickly?
Keto bakes brown quickly because ground almonds and other nut flours colour faster in the oven than wheat flour. Bake on the middle shelf, follow the recipe's temperature, which is often lower than usual, and check a few minutes early. If the edges darken before the middle is set, cover the bake loosely with foil.
Why is my keto icing grainy?
Keto icing turns grainy when it's made with a granulated sweetener, because the crystals can't dissolve in the small amount of liquid in icing. Use a powdered sweetener instead, such as our Powdered Erythritol & Stevia Blend, which swaps 1:1 for icing sugar. Sieve it first and ice your bakes close to serving.
Do I need xanthan gum for keto baking?
Not always, but most keto cakes, biscuits and pastry hold together better with it. Without gluten, a small amount, usually ¼ to 1 teaspoon, binds the bake. You can use psyllium husk powder instead, at about 2 teaspoons for every 1 teaspoon of xanthan gum, with a little extra liquid and a 10-minute rest.
