Brownie Protein Shake is perfect for when you bake a big batch of brownies, and want to make it last longer! It’s got protein brownies and protein powder for a double dose of goodness.

Okay not gonna lie, but I had a recipe that failed on me so I turned it into this protein brownie shake! Think double protein here – it’s got a protein brownie and protein powder inside – and a dose of nutrition from cauliflower in ther too.

Whether you have a recipe gone bad, or wondering what to do with leftover brownies or just baked a fresh batch of protein brownies – you’re not going to regret trying out this shake!

Ingredients in Brownie Protein Shake

This brownie protein shake is made with a protein brownie, protein powder and another 2 pantry staples. Here’s all the ingredients:

Protein Brownies: I recommend using this fudgy protein brownie recipe.
Vanilla Protein Powder: This is the core ingredient to this chocolate brownie protein shake, so use a good quality one.
I recommend Whey-Casein from Quest Nutrition for this recipe to make it thick and smooth.
Frozen Cauliflower
Unsweetened Almond Milk

How do you make the Perfect Leftover Brownie Protein Shake?

This leftover brownie protein shake is a simple recipe;

Blend smoothie ingredients in a blender (frozen cauliflower, protein powder, milk).
Add brownie pieces and blend again.
Pour into glass and top with more crumbled brownie.

Tips for Perfect Protein Brownie Smoothie

Use whey-casein protein powder as specified. It works well with the ratio of ingredients here.
Whey-casein absorbs more liquid, and whey absorbs less, so you need to adjust the liquid accordingly for the right consistency of this brownie protein smoothie.

Put the wet ingredients in the blender first, then the dry ingredients. This prevents the dry ingredients from sticking to the bottom of the blender.

Scrape down the sides of the blender as needed so everything mixes well.

More options for Healthy Brownie Smoothie

I made this a low-calorie and healthy leftover brownie smoothie with the list of ingredients I mentioned, but here’s some other alternatives.

Frozen Cauliflower: Frozen zucchini; Or some frozen yogurt!
Almond Milk: Other non-dairy or regular milk
Protein Brownie: Any other leftover brownies

If you’re Vegan, use a plant based protein powder and brownie; I recommend Dymatize Complete Plant Protein Powder.
