  • 6-8 tbs blackberries frozen or fresh. Rasperries would also work
  • 2 tbs avocado oil or coconut (butter will also work)
  • 1 tbs milk of choice
  • 2 tbs honey
  • 3 tbs flour
  • 2 tbs cocoa powder
  • 1.5 tbs chocolate chips or more
  • 1/4 tsp vanilla extract
  • pinch salt
  • pinch baking soda
  • dollop whipped cream


  • Place blackberries in a mug, mason jar, or oven-safe dish, and cook in the microwave for 5-10 seconds for fresh berries or 15 seconds for frozen.
  • Add wet ingredients and stir.
  • Mix in dry ingredients well.
  • Fold in chocolate chips.
  • Place in the microwave on 45-60 seconds.
  • Allow to cool for a few minutes.
  • Top with whipped cream (optional, but makes it really good), more berries and chocolate chips.


While whipped cream is totally optional, it really adds a nice balance to the chocolate. Even just a splash of cream or milk on top would be yummy.
This can be made gluten free using a gluten free one-to-one flour. The texture will be a bit different, but my daughter still really liked it.
