Healthy Chocolate Chip Marble Cake


Healthy High Protein Chocolate Chip Marble Cake Bars made using whole food ingredients and PEScience protein powder.



After a long Sunday, my boyfriend and I decided to take it easy and order a pizza for dinner. I know, I know, it goes against like everything I stand for. But pizza is life and everyone deserves it every now and then! 😉


So I’m ordering pizza online from Dominos when I see the most delicious looking marble cookie brownies being advertised for dessert. I knew instantly what my next baking venture would be. Today I set out to make a healthy version of those brownies. Instead, my “brownies” came out looking more like “cake” which is totally fine because who doesn’t love cake??



I used PEScience Frosted Chocolate Cupcake in this recipe and it made these cake bars extra sweet without adding all the extra sugar! Get 30% OFF all PEScience products by using code PBCHOCO at

Healthy Chocolate Chip Marble Cake Bars

A healthy decadent chocolate chip marble cake made using whole food ingredients and protein powder!


  • 3/4 c brown rice flour or gluten-free oat flour
  • 1/2 c finely ground almond flour
  • 2 tbsp Truvia or coconut sugar
  • 32g protein powder (I used PEScience Frosted Chocolate Cupcake 30% OFF code PBCHOCO)
  • 2 tbsp coconut oil, melted
  • 1 egg, room temperature
  • 1 egg yolk, room temperature
  • 1 tsp vanilla extract
  • 1/2 tsp baking soda
  • 1/2 tsp baking powder
  • 3 tbsp unsweetened cocoa powder
  • 1/2 c unsweetened applesauce, room temperature
  • 1 tbsp chocolate chips


  • Preheat oven to 350F and prepare an 8x8" pan with parchment paper.
  • Place the flours, Truvia, baking soda and powder into a mixing bowl and stir until combined. Pour the flour mix into a mixer. Add the egg, egg yolk, melted coconut oil, vanilla extract and 1/4 cup applesauce. Beat until everything is incorporated and you have a thick batter. Scoop out 1/2 cup of the batter, fold in chocolate chips and set a side.
  • Add the cocoa powder, protein powder and 1/4 cup applesauce to the remaining batter and beat until smooth. Spread chocolate batter into the bottom of the prepared pan using a rubber spatula (it helps if you wet it slightly first to prevent sticking).
  • Use a cookie scoop to drop dollops of the chocolate chip batter over the chocolate layer until you have used it all. Mine was 5 scoops. Use a knife to swirl the batters together.
  • Bake for 17-19 minutes.
  • Let cool before cutting into 9 bars and serving.
