Preheat oven to 350℉ and line a standard muffin tin.
To make the cupcakes, combine the almond milk, vinegar, and vanilla extract. Set aside.
In a separate bowl, mix together the Keto Chow, almond flour, coconut flour, cocoa powder, and baking soda.
Cream butter with an electric mixer until light and fluffy. Beat in the erythritol; then beat in the eggs, one at a time.
Beat in half the flour mixture. Slowly mix in the almond milk mixture a little at a time so it doesn’t splash out of the bowl, then beat in the remaining flour mixture.
Mix in the red food coloring. Add enough to make the batter bright red. The amount needed will depend on what type of coloring you use.
Divide the batter evenly among the prepared muffin cups.
Bake for about 25-30 minutes, or until slightly firm to the touch and lightly browned around the edges.
Allow the cupcakes to cool completely before frosting.
