Vegan Keto Brownies -  one of my vegan keto favorites of all time!

When you're doing vegan keto and that sweet craving kicks... that's truly not the best time being on keto - especially in the beginning, when the cravings do actually come more frequently.

When I personally experienced this in the past whilst on vegan keto it had me thinking ‘hey, it must be possible to create a great treat, that’s delicious and at the same time keto friendly’. The challenge was accepted and this Vegan Keto Brownie Recipe was born!

This low carb brownies recipe is:

  • 100% vegan, made only plant based ingredients
  • naturally gluten-free
  • sweet-tasting
  • satisfying and delicious
  • chocoalte-y
  • low carb
  • vegan keto-friendly
  • the perfect keto snack
  • simply a treat

And these vegan keto brownies were the result of that challenge that I set myself! Incredible, right? And only using a handful of ingredients too - you’ll be surprised that these can be created of such little ingredients and completely without refined sugar and practically also without flour.

This recipe actually started as some kind of experiment - something along the lines of ‘I wonder whether it’s possible to create a sweet treat without flour’. So I went into the kitchen, drew out my low-carb ingredients, and simply started blending some ingredients together in a bowl. And the magic happened: it worked out on the first attempt and these tasty brownies were the result! Crazy that there’s no wheat flour in them, right?

Why I am stressing ‘wheat’ flour? Well technically there is a type of flour in them - if you would count peanut flour into the flour family, it’s basically just dried and very finely ground peanuts 😉

Ingredients for this recipe

These vegan keto brownies are made with only a handful of ingredients:

  • ground flaxseeds: these add some natural oils into the recipe and also help bind it together
  • peanut butter: the base ingredient for this recipe! The peanut butter adds some fats into these brownies. For best results, use smooth peanut butter with peanuts as the only ingredient.
  • apple cider cider: in combination with the dairy-free milk, the vinegar creates a vegan version of buttermilk which helps the keto brownies rise in the oven.
  • baking powder: reacts with the vegan buttermilk in the recipe and gives these vegan keto brownies a soft and fluffy texture.
  • vanilla extract: to round up the flavor profile of this keto treat.
  • granulated sugar replacement: to add both sweetness and texture to the keto bake. I use the granulated version of Natvia for this recipe.
  • plant milk: soy is often my go-to, but use your personal favorite, such as almond milk or coconut milk.
  • peanut flour: we add a small amount of peanut flour to the mixto help bind the ingredients together. If you don't have peanut flour to hand, then swap for almond or coconut flour.
  • raw cacao powder: adding the delicious chocolate flavor to these keto brownies!

How to make vegan keto brownies

Step 1: Preparation

Preheat your oven to 180°C.

To make these keto brownies, start by creating vegan buttermilk. This is done by mixing the non-dairy milk with apple cider vinegar and setting it aside for about 10 minutes to let it curdle. After this time, it's ready to use in the recipe.

Step 2: Combine the batter

In a medium-size bowl, combine the flaxseeds, baking powder, granulated sugar replacement, peanut flour and raw cacao powder.

Stir in the peanut butter and vanilla extract, then pour in the vegan buttermilk mixture. Combine with a spatula until you get a smooth brownie batter.

Step 3: Baking and slicing

Transfer the batter into a greased and lined baking tin and bake for 15-20 minutes or until firm on the top

Allow for the brownies to cool down entirely before slicing - this is when they will firm up.

Storing the vegan keto brownies

Keep your sliced vegan keto brownies in an air-tight container in the fridge for up to 5 days.
