15 Minute No-Bake Chocolate Peanut Butter Oat Bars

These No-Bake Chocolate Peanut Butter Oat Bars come together in just 10 minutes, plus a quick chill in the freezer, and make the perfect healthy vegan snack. Protein powder is totally optional, but it helps boost these bars to about 8 grams of protein per bar, alongside hearty oat flour and large flake oats. Finished with a rich chocolate coating on top, they’re easy, satisfying, and seriously delicious.

Equipment

  • 9 inch loaf tin

Ingredients

  • 1 cup oat flour see note
  • ½ cup large flake oats
  • 1 scoop vanilla protein powder
  • ½ tsp salt
  • 2 tbsp coconut oil melted
  • ¼ cup maple syrup
  • ½ cup natural peanut butter
  • 2 tbsp plant-based milk I used soy milk
  • 1 tsp vanilla extract
  • 1 cup chocolate chips melted

Instructions

  • Line a loaf tin with parchment paper.
  • In a large bowl, stir together the oat flour, large flake oats, protein powder if using and salt.
  • In a separate bowl, whisk together the coconut oil, maple syrup, peanut butter, plant-based milk and vanilla until well combined.
  • Pour the wet ingredients into the dry ingredients and stir them well to combine. It will be a thick dough.
  • Spoon the dough into the loaf tin. Using clean hands, press the oat mixture to the bottom of the tin until it’s evenly distributed.
  • Pour the melted chocolate on top of the oat mixture and use the back of a spoon to spread it evenly. Place it in the freezer for 10 minutes or until it’s set.

Notes

I make my oat flour from scratch by blending large flake oats, but you can also purchase it from a store pre-made. 
Storing leftovers: Refrigerate leftovers in an airtight container for up to one week.
