Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a mini muffin tin or line it with paper liners.
Mix Dry Ingredients: In a medium-sized bowl, whisk together almond flour, unsweetened cocoa powder, and baking powder.
Combine Wet Ingredients: In a separate bowl, beat together eggs, melted butter (or coconut oil), vanilla extract, and erythritol until smooth.
Combine Wet and Dry Ingredients: Gradually add the wet ingredients to the dry mixture, stirring gently until fully combined.
Scoop the Batter: Using a spoon or small cookie scoop, portion the batter evenly into the mini muffin tin, filling each cup about 2/3 full.
Bake: Bake in the preheated oven for 10-12 minutes, or until a toothpick inserted into the center comes out clean or with just a few crumbs.
Cool: Allow the brownie bites to cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely.
Serve: Once cooled, enjoy your delicious Keto Brownie Bites as a quick snack, dessert, or treat.
