Mocha Brownie Protein Bars
Yields: 6 protein bars
These healthy protein bars taste like a cross between a mocha and fudgy brownie! They’re great for snacks, a quick energy boost, or curbing dessert cravings. For best results, store the bars in an airtight container in the refrigerator for up to 1 week.
  • 3 scoops (90g) plant-based vanilla protein powder (I used PlantFusion)
  • ½ cup (40g) unsweetened cocoa powder (measured correctly)
  • ½ cup (50g) old-fashioned oats (gluten-free if necessary)
  • 2 tbsp (28g) Truvia (or other sweetener, to taste)
  • 1 cup (240mL) cold coffee
  1. Line a 9x5” loaf pan with parchment paper.
  2. In a large bowl, stir together the protein powder, cocoa powder, oats, and Truvia. Mix in the cold coffee until fully incorporated. Transfer the mixture into the prepared pan, and evenly press it down with a spatula. Chill for at least 2 hours, or until firm, before slicing into bars.
Notes: Not all protein powders absorb liquids or weigh the same. I have only tested this recipe with PlantFusion vanilla bean protein powder. If using a different plant-based protein powder, start with 3 scoops (even if that weighs differently), and add more protein powder or coffee as necessary. Do not substitute whey-based protein powders.

The bars can be somewhat fragile and flimsy, even if eaten directly from the refrigerator. For firmer bars, freeze for 10-20 minutes before eating.

For a more prominent coffee flavor, use double-strength coffee instead.
