Keto Almond Butter Cookies
These keto almond butter cookies are the recipe that makes keto baking feel completely effortless, and they might just become the most-requested treat in your household, keto or not. Four pantry staples, natural almond butter, egg, powdered erythritol, and vanilla, come together in a single bowl to produce a cookie with a perfectly crispy edge, a fudgy-chewy centre, and a deep, nutty richness that satisfies every craving.
There is no flour to measure, no butter to soften, no dairy of any kind, and zero refined sugar. Just honest ingredients that happen to produce an outstanding cookie. At only 3g net carbs per cookie, they fit comfortably into strict ketogenic macros without any creative accounting.
What makes this recipe so reliable is the simplicity of the chemistry. Almond butter is naturally high in fat and protein, which means it acts as the structural base of the cookie, replacing both the flour and the butter you would find in a conventional recipe. The single egg binds everything together and gives the cookies their characteristic chew. Baking soda provides a small amount of lift and helps the edges crisp up beautifully in the oven. And powdered erythritol (rather than granular) dissolves fully into the dough so there is no grittiness in the finished cookie.
The crosshatch pattern pressed with a fork is more than aesthetic, it flattens the dough evenly and creates additional surface area for crisping. This is the same technique used in classic peanut butter cookies, and it works just as beautifully here.
One thing every first-time baker needs to know: these cookies will look underdone when they come out of the oven. The centres will appear soft and the cookies will feel fragile. This is completely normal and completely correct. Do not overbake them chasing a firmer look, they will firm up to the perfect texture as they cool on the tray. Overbaking is the single most common mistake with this recipe and results in dry, crumbly cookies instead of the fudgy result you are after.
The recipe takes five minutes to mix, 12 minutes to bake, and produces 16 generously sized cookies. They keep beautifully in an airtight container for up to five days at room temperature, and the texture actually improves over the first two to three days as the cookies settle and the chewiness intensifies. They also freeze exceptionally well for up to two months.
Almond butter cookies are also naturally gluten-free and dairy-free, making them a genuinely crowd-pleasing option for people with dietary restrictions beyond keto. Swap the egg for a flax egg and they become vegan. Swap the almond butter for sunflower seed butter and they become nut-free. The base recipe is endlessly adaptable.
For variations, press a few sugar-free dark chocolate chips into the tops before baking for a keto chocolate chip cookie moment. Add a teaspoon of cinnamon and roll the balls in erythritol before baking for a snickerdoodle-style version. Or fold in a tablespoon of unsweetened cocoa powder for a mocha-almond variation. The plain cookie is the perfect canvas.
Whether you are new to keto baking or a seasoned low-carb baker, this is the cookie recipe to have in your back pocket. It is reliable, fast, made with ingredients you likely already have, and genuinely delicious even to people who are not following any particular diet.
Ingredients
- 250 g smooth almond butter (natural, no added sugar or oils — stir well before measuring if oil has separated)
- 1 large egg (room temperature — helps the dough come together smoothly)
- 80 g powdered erythritol or monk fruit sweetener (use powdered not granular to avoid grittiness; allulose gives a chewier result)
- 1 tsp pure vanilla extract (enhances the nuttiness of the almond butter)
- ½ tsp baking soda (helps the edges crisp and gives slight lift — do not skip)
- 1 pinch sea salt (balances sweetness and enhances flavour; flaky salt on top is also excellent)
Instructions
- 1
Preheat oven to 175°C (155°C fan) / 350°F. Line two baking trays with baking paper.
Make sure your oven is fully preheated before the tray goes in — an under-heated oven leads to flat, greasy cookies.
- 2
Mix all ingredients in a bowl until a smooth, thick dough forms.
The dough will be slightly oily from the almond butter — this is correct. If your almond butter was refrigerated, let it come to room temperature first for easier mixing.
- 3
Roll into 16 equal balls and place on lined trays, spacing 5cm apart.
Use a cookie scoop or kitchen scales to keep the balls even — this ensures all cookies bake at the same rate.
- 4
Flatten each ball gently with a fork, pressing a crosshatch pattern into the surface.
Do not flatten too thin — about 1cm thick bakes to the best texture. Dip the fork in a little water between presses to prevent sticking.
- 5
Bake 11–13 minutes until the edges are golden and the centres look just set.
They will be very soft when hot — do not try to move them yet. Watch for golden edges; the centres should look just set, not wet.
- 6
Cool on the tray for 10 minutes before transferring — they firm up as they cool.
Patience is key. Moving too early will break the cookies. The cookies will feel completely firm once fully cooled — this takes the full 10 minutes minimum.

Pro Tips
- ✓
The cookies look and feel underdone when they first come out of the oven, that is correct and intentional. They firm up to the perfect fudgy-chewy texture as they cool. Pull them at golden edges, not firmness.
- ✓
Always use natural almond butter with no added sugar, palm oil, or stabilisers. Brands with only almonds (and possibly salt) listed on the label are what you want. Stir well before measuring if the oil has separated.
- ✓
Use powdered erythritol rather than granular. Granular erythritol does not dissolve fully and can leave a gritty texture. If you only have granular, pulse it in a blender or food processor for 30 seconds to powder it yourself.
- ✓
For even chewier cookies, refrigerate the dough for 30 minutes before rolling and baking. The cold dough spreads less in the oven and produces a thicker, fudgier result.
- ✓
Press 3–4 sugar-free dark chocolate chips (Lily's or ChocZero) into the top of each cookie immediately after baking while still hot, they melt slightly and set beautifully as the cookie cools.
- ✓
Sprinkle a small pinch of flaky sea salt on each cookie right before baking to amplify the flavour and add a professional bakery-style finish.
