What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 4 tbsp all-purpose flour
  • 3 tbsp granulated sugar
  • 1 tbsp unsweetened cocoa powder
  • 3 tbsp buttermilk
  • 2 tbsp melted butter
  • 0.5 tsp red food coloring

Step by step instructions

Step 1: Mix Dry Ingredients

Combine flour, sugar, and cocoa powder in a large microwave-safe mug and stir until blended.

Step 2: Add Wet Ingredients

Add the buttermilk, melted butter, and red food coloring to the mug and stir until a smooth, uniformly red batter forms.

Step 3: Microwave the Cake

Microwave on high for 75 to 90 seconds until the cake rises and is just set on the surface with no wet batter visible.

Step 4: Top with Cream Cheese Drizzle

Whisk a tablespoon of softened cream cheese with a teaspoon of powdered sugar and drizzle over the warm cake before serving.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • buttermilk → regular milk mixed with half a teaspoon of white vinegar and let sit for one minute
  • red food coloring → beet powder for a natural red color alternative

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Using too little cocoa powder mutes the classic subtle chocolate flavor that defines red velvet
  • Adding too much red food coloring can make the cake taste slightly bitter so measure carefully
