  • Transfer peanut butter protein oat dough to the parchment paper covered baking ban and top with more chocolate chips.
  • Bake in hot oven for 15 to 20 minutes and let cool at room temperature before slicing into 6 bars.

Protein oatmeal brownie bars

  • Melt dark chocolate (with hint of coconut oil, if necessary).
  • In a large mixing bowl, mash the ripe bananas. Add to the banana mixture melted chocolate, maple syrup (optional) and pinch salt. Stir until you get a well combined mixture.
  • Add rolled oats and protein powder to the wet dough. Mix well until you get a doughy texture (see notes*).
  • Transfer oat brownie dough to the parchment paper covered baking ban and top with more chocolate chips.
  • Bake in hot oven for 15 to 20 minutes and let cool at room temperature before slicing into 6 bars.

Raffaello protein oatmeal bars

  • Start by mashing the ripe bananas in a large mixing bowl. Add to the banana mixture almond butter and optionally maple syrup. Stir until you get a well combined mixture.
  • Add rolled oats, protein powder and desiccated coconut to the wet dough. Mix well until you get a doughy texture (see notes*).
  • Transfer Raffaello oatmeal dough to the parchment paper covered baking ban.
  • Bake in hot oven for 15 to 20 minutes and let cool at room temperature before slicing into 6 bars. Serve with a sprinkle of coconut flakes on top, if you desire.

Notes

  • You can use vegan protein powder, whey or casein (see recipe description for more details).
  • If using vegan protein powder or casein, your dough may require 1 to 2 tbsp of milk to get fixed (dough has to be thick but not too dry).
  • If using whey protein powder, your dough may require some more oats to get fixed (dough has to be thick but not too dry).
  • Bananas sweeten these bars naturally. For sweeter oatmeal bars, add a couple tablespoons of maple syrup or honey. Taste the dough and adjust with maple syrup or honey if necessary.
