Tips for Perfect Protein Powder Chunky Monkey Brownies

These protein powder chunky monkey brownies are dense and just spot on, but actually very easy to make!

Use room temperature milk and yogurt;
This is so the wet ingredients and dry ingredients of the brownie and banana layers can mix well.

Use completely mashed banana from a ripe banana – this is sweeter and so you need less sugar in the recipe.

Use Runny Peanut Butter also so that it mixes well into the batter

Don’t over-mix the batter!
Make sure you gently fold the dry mix into the wet to combine them.
If you over-mix it, the protein powder will make the fudgy brownies and banana tough, dense and gummy.

Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter and have sugar free and healthy brownies.

Don’t over-bake the brownies or they might get tough; Remove when the tester/knife comes out still moist.
Underbaking a little is okay.
