One of my favorite websites is called "I Breathe I'm Hungry." The owner posts keto-friendly recipes and this is one I recently made and like very much. Her recipe is called Chocolate Zucchini Cupcakes, but I have made several modifications. I'll put a link to the original recipe at the bottom of this post, for those who are interested.
INGREDIENTS: (My modifications are indicated with an *)
6 Tbsp butter, melted
2 eggs
1 tsp vanilla extract
1/4 cup full fat coconut milk *
1/2 avocado, mashed *
1/2 cup almond flour *
1/2 cup, plus 3 Tbsp coconut flour *
1/4 cup granulated sugar substitute (I used monk fruit sweetener)
3 Tbsp premium cocoa powder
1/4 tsp xanthan gum
pinch of salt
2 tsp baking powder
Preheat the oven to 350 degrees (F)
Combine the wet ingredients (butter, eggs, vanilla extract, coconut milk, avocado) in a bowl and mix well (or if you prefer, use a blender or Magic Bullet mixer)
Combine the dry ingredients (almond flour, coconut flour, sweetener, cocoa powder, salt, baking powder, xanthan gum) in a medium bowl and stir until mixed and there are no lumps.
Pour the wet ingredients into the dry ingredients and stir until the liquid is absorbed and a thick batter is formed.
Spoon the batter evenly into 9 cupcake liners or greased tins.
Bake at 350 degrees (F) for 22-23 minutes. Remove and cool before frosting. (I frosted mine the first time I made them, and the frosting is good, but for me - not necessary. Since then, I've done without the frosting and these cupcakes are so chocolately and yummy, they satisfy my need for something sweet.)
