Ingredients for this No Bake Freezer Brownies

This Freezer Protein Brownie recipe calls for just six simple, pantry-friendly ingredients:

  • Chocolate  Protein Powder - a rich chocolate flavor and boosts protein content.
    I used whey isolate Chocolate protein powder from Isopure. 
  • Unsweetened Cocoa Powder
  • Coconut Flour - Provides structure while keeping carbs low, making them Low-Carb Protein Brownies.
  • Some Creamy Almond Butter; I recommend Almond Butter from American Dream Nut Butter for a high protein version.
    Code HAYLSKITCHEN gives you a discount on the nut butter.
  • Unsweetened Almond Milk  - Brings the mixture together with a creamy texture.
  • Vanilla Extract - For a subtle, sweet aroma.

How to Make Protein Brownies Without Baking

With no baking and no oven needed, these guilt free healthy brownies are really easy. Here's what you need to do.

Step 1: Prepare the Dough

  1. In a mixing bowl, combine whey chocolate protein powder, coconut flour, and cocoa powder. Stir until the dry ingredients are evenly mixed.
  2. Add creamy almond butter, unsweetened almond milk, and vanilla extract. Stir with a spatula or your hands until a dough forms. If it feels too dry, add a little more almond milk.

Step 2: Shape and Set

  1. Line a small baking dish or loaf pan with parchment paper. Press the dough into the dish, spreading it evenly to create a flat layer.
  2. Smooth the top with the back of a spoon for a clean finish.
  3. Press on some chocolate chips if you'd like.

Step 3: Freeze and Slice

  1. Place the dish in the freezer for 20-30 minutes, or until firm.
  2. Once set, remove from the freezer and cut into squares. Store in the freezer for a quick healthy freezer dessert anytime you need it.

Tips for the perfect No Bake Brownies with Protein Powder

These no bake protein powder freezer brownies are really easy to make, but here's some tips to get them perfect!

  • Use whey protein powder since it works well with the ratio of ingredients here; Whey absorbs less moisture, so you would have to increase the amount of milk if you use whey-casein or plant-based.
  • Add milk little at a time or the mix will get too runny. Only add more if needed.
    Keep mixing; the dough will come together.
  • Taste the mixture and see if you need some extra sweetener. I'd recommend using stevia powder to maintain the consistency of the dough and have sugar free no bake chocolate protein cookie.

To store:

Other Options for Healthy Freezer Brownies

  • Adjust Sweetness: If you prefer a sweeter brownie, add a drizzle of sugar-free maple syrup or a few drops of liquid stevia.
  • Substitute Nut Butters: Use peanut butter or sunflower seed butter for a different flavor profile.
    Cashew butter or Tahini would also work well!
  • Alternative Milk: Instead of almond milk, feel free to use any other non-dairy or dairy-based milk.
  • Enhance Texture: Sprinkle in crushed nuts, seeds, or sugar-free chocolate chips for added crunch.
  • Batch Variations: Double the recipe and try layering with Greek yogurt frosting for an extra protein kick.

Vegan Fridge Brownies Recipe

To make this fridge protein brownie recipe Vegan, use a plant based protein powder like this one from KOS.
