How to make Peanut Butter Cup Loaf with Protein Powder

It might sound complicated making this high protein peanut butter cup loaf with protein powder, but it really is a simple recipe. Just mix and bake!

Preheat and Prep:

Preheat your oven to 350°F (175°C). Grease and line a standard loaf pan with parchment paper.

Mix Dry Ingredients:

In a large bowl, whisk together the flour, vanilla protein powder, peanut butter powder, unflavored protein powder and baking soda until well combined.

Combine Wet Ingredients:

In another bowl, mix together the hot water, applesauce and melted butter until smooth.

Create Batter:

Gently whisk the wet ingredients into the dry ingredients until a thick batter forms.
Fold in some of the chopped peanut butter cups qne Reese’s pieces (just for a second so the color doesn’t bleed too much!).

Bake to Perfection:

Pour the batter into the prepared loaf pan and spread it evenly. Top with remaining PB cups and pieces.

Bake for 25 minutes, cover with foil and bake another 20 minutes or until a toothpick inserted into the center comes out clean.

Cool:

Allow the Reese’s loaf to cool in the pan for 10 minutes, then transfer it to a wire rack to cool.
Slice into 10 delectable portions.

Tips for perfect Reese’s Protein Bread

This loaf is easy to make, delicious to eat, and the perfect balance of sweet and healthy.

Use whey-casein protein powder (or plant-based protein powder) since It works well with the ratio of ingredients in this healthy Reese’s bread dessert recipe.
Whey-casein absorbs more liquid, and whey absorbs less, so you need to adjust the liquid accordingly.

Use melted butter so that it mixes well into the cake batter.

Don’t overmix the batter!
Pour the wet mix into the dry mix and whisk until combined. Don’t over-mix it or too much gluten will develop, which is what will make the cake gummy and dense.
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 low sugar Reese’s loaf.

Don’t let the batter sit out too long; Pour immediately into baking pan and bake to avoid any reactions between the ingredients.

Don’t over-bake the peanut butter cup loaf or it will get tough; Remove when the tester/knife comes out just dry, but moist.

How to store Peanut Butter Cup Loaf Cake?

To store your Peanut Butter Cup Protein Loaf cake, follow these simple steps:

Room Temperature: If you plan to eat it within 1-2 days, you can store the loaf in an airtight container at room temperature. Make sure it’s kept in a cool, dry place.
Refrigerator: For longer storage (up to 5 days), place it in an airtight container and place in the refrigerator. This will help maintain its moisture and freshness.
Freezer: To store for up to 3 months, slice the loaf and wrap individual slices in plastic wrap or place them in freezer-safe bags. Thaw in the fridge overnight or reheat in the microwave when ready to enjoy!

Alternate ingredients for Healthy Reese’s Loaf

For the perfect healthy, low calorie Reese’s loaf loaf recipe, I recommend using the ingredients and brands listed, but here’s some healthy alternatives you can try.

Whole Wheat Pastry Flour: Use All purpose flour or 1:1 Gluten Free Baking Flour in the same amount by weight not cups.
Coconut Flour: ½ cup more Flour or ½ cup Oat Flour
Melted Butter: Melted Coconut Oil or Dairy Free Butter
