The base of the brownies, kidney beans provide a good source of fiber and plant-based protein to keep you full. They act as a binder.

Almond butter

In addition to protein and healthy fats, almond butter boosts flavor and texture. Its nutty richness takes the brownies up a notch.

Maple syrup

With some natural sweetness, maple syrup allows you to use less added sugar. It provides moisture and adds a unique rich flavor.

Protein powder

Extra protein powder thickens the batter for a fudgy texture while also increasing nutrition.

Cocoa powder

Unsweetened cocoa provides that rich chocolate flavor we crave without the dairy. It packs in antioxidants too.

Adding some dark chocolate to the porridge is my favorite thing! I really can’t miss this ingredient anymore! It gives a rich flavor to the porridge and goes so well with fruits and nuts!

Sea salt

A touch of sea salt balances out the sweetness and enhances all the deep chocolate notes. That is my secret ingredient for most of the desserts.

The possibilities are endless when it comes to customizing this recipe to your tastes or what you have on hand.

  • Swap kidney beans for other legumes (chickpeas, black beans, cannellini beans)
  • Add crunch with nuts (walnuts, pecan nuts, almonds, cashews)
  • Mix in dried fruit (dried apricots, cranberries, sultanas, cherries)
  • Fold in chocolate (dark, milk, white, butterscotch chips)
  • Stir in other mix-ins (peanut, almond, cashew, coconut flakes, granola)
  • Adjust sweeteners (maple syrup, agave syrup, honey, applesauce)
  • Experiment with spices (cinnamon, nutmeg, cardamom, vanilla bean, tonka bean)

When customizing these brownies, be mindful of how each ingredient affects nutrients and calories – for example, choosing dark chocolate over milk chocolate will mean less sugar, or opting for almond butter over peanut butter gives you more healthy fats.

Keep your health goals in focus when substituting or adding new mix-ins to your protein brownie.
