  • dietary features: vegan, gluten-free, nut-free, oil-free
  • healthier snacking: well-balanced for a healthier, low-sugar snack and dessert option
  • quick and easy: you’ll need just 5 ingredients and 20 minutes

Ingredients Notes

  • protein powder – works best with a pea protein-based vegan protein powder such as Vega, NuZest, Orgain or Bob’s Red Mill
  • oats – rolled oats, quick oats and old fashioned oats all work, be sure to use gluten-free certified if needed
  • cocoa powder – regular baking cocoa powder or raw cacao powder both work here
  • chocolate chips – use dairy-free chocolate chips to keep them vegan, I like Camino and Enjoy Life
  • banana – lightly spotty banana works great, over so ripe it’s mushy and definitely not under ripe

Step by Step Instructions

Before You Start: Preheat the oven to 350 F.

Step 1. Mash the banana into a smooth paste. I like to use an immersion blender for this but a fork will do trick too.

Step 2. Add the rest of the ingredients and mix into a thick dough.

Notes and Tips

  • Cooling: Don’t skip letting them cool in the pan for 10 minutes. It helps them hold together well.
  • For Best Results: Use a kitchen scale to measure ingredients.
  • Whey: These have not been tested with whey protein powder and I don’t recommend using it as it has a different texture and acts differently in baking.
  • Sweetening: These are on the healthy side and not super sweet or decadent. For additional sweetness, add up to 2 tbsp maple syrup, coconut sugar or agave, or sweeten to taste with a sugar-free sweetener such as stevia or monk fruit.

  • Fridge: Let cool then store in a sealed container for up to 5 days.
  • Freezer: Let cool then store in a sealed container or freezer-safe bag for up to 3 months.
  • Reheating & Thawing: If frozen, thaw at room temperature or in the fridge. Reheat in the oven or microwave if desired. They’re yummy warmed up and topped with almond or peanut butter!
