How to Make Only 5-Minute Sugar-Free, Flourless Chocolate Cake

  1. Melt the chocolate & butter. Place chocolate chips and butter in a microwave-safe bowl. Heat in 20-second intervals, stirring until smooth.

  3. Add cocoa powder. Stir in unsweetened cocoa powder until fully combined.
  4. Microwave & set. Pour the batter into a greased ramekin or dish. Microwave on high for 1½–2 minutes until the cake is set on top but still soft inside.

It’s honestly that simple—rich, warm chocolate cake in 5 minutes flat.
