Preheat your oven to 350°F (175°C). This ensures your cupcakes bake evenly.
Line a muffin tin with cupcake liners or grease it lightly with your favorite oil.
In a mixing bowl, whisk together the almond flour, cocoa powder, baking powder, salt, and powdered erythritol until well combined.
In another bowl, whisk together the milk of choice and eggs (or flax eggs) until smooth.
Pour the wet mixture into the dry ingredients, stirring gently until just combined. Be careful not to overmix!
Spoon the batter into the prepared muffin tin, filling each cup about 2/3 full.
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cupcakes to cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
