  • 1 ½ cups flour
  • 2 teaspoons Baking Powder

  • 1 egg
  • cup cocoa powder
  • ¾ cup milk
  • 1 teaspoon vanilla

Chocolate ganache

  • ½ cup dark chocolate
  • cup cream


  • Line or grease a microwave cake pan. (I used a silicone cake pan and find that there is no need to grease or line it)
  • Add dry ingredients in a large bowl and mix.
  • Add wet ingredients to the dry ingredients and whisk together until well combined.
  • Add to you baking pan and cook in a microwave for 5 min on high - 1200watts.
  • While the cake is cooking make the chocolate ganache for the cake.
  • Let the cake cool for 5-10 in pan before removing.
  • Once cake has cooled pour over chocolate ganache.

Chocolate ganache

  • Heat cream on a low heat until hot - but do not let the cream boil.
  • Pour hot cream over the dark chocolate and let sit for 5 minutes to soften and melt the chocolate.
  • Stir together until ganache is smooth and creamy.
  • Let sit for 10 minutes to thicken up a little bit.
  • Pour over cake.


If you do not want to use coffee in, your cake you can just sub it for hot water.
I cook my cake on 1200 watts, but every microwave is a bit different. You may need to change you cooking time by 30 seconds depending on you microwave.
