Ingredients

Chocolate whey protein powder

Chocolate whey protein powder provides the base for the chocolate batter, giving it a rich flavor and a high-protein content. When protein concentrate or whey protein isolate would work here.

Cocoa powder

Cocoa powder enhances the chocolate flavor and adds depth to the fudge.

Water

Water helps combine the ingredients and creates the right texture for both batters.

Almond butter

Almond butter gives the fudge body and adds healthy fats.

Salt

Salt enhances the chocolate flavor and balances the sweetness. Don't skip it!

Unflavored whey protein powder

Unflavored whey protein powder serves as the base for the peppermint batter, offering protein without any flavor that may overpower the peppermint flavor.

Alcohol-free peppermint extract

Alcohol-free peppermint extract provides the refreshing, minty flavor. I think it is important to use alcohol-free peppermint flavoring here, since this isn't a cooked recipe. Extracts containing alcohol really upset the natural flavors in no-bake recipes (in my opinion).

Agave nectar

Agave nectar adds a touch of sweetness to the peppermint batter. Feel free to sub your favorite liquid or powdered sweetener instead. (Granulated sweeteners are not recommended, as they may not dissolve fully, leaving an undesirable mouthfeel.)

Coconut flour

Coconut flour helps thicken the peppermint batter and complements the peppermint flavor.

Equipment Needed

Kitchen scale: A kitchen scale ensures accurate measurements for consistent results.

Mixing bowls: Separate bowls keep the chocolate and peppermint batters easy to manage.

Parchment paper: Parchment paper prevents sticking and makes it easy to remove the fudge.

Loaf pan: A loaf pan provides the perfect size for the recipe and perfect shape for cutting the fudge into squares.

Butter knife: A butter knife (or back end of a spoon) creates the swirled pattern.

Instructions

1. Line a loaf pan with parchment paper.

2. Mix the chocolate whey protein powder with the cocoa powder in a bowl. Add water and mix well.

3. Add almond butter and salt to the chocolate mixture. Mix until smooth. Spoon the chocolate batter into the pan.

4. In a separate bowl, mix the unflavored whey protein powder with water. Add peppermint extract and agave nectar. Mix well.

5. Add coconut flour to the peppermint batter and mix until smooth.

6. Spoon the peppermint batter over the chocolate batter, leaving some of the chocolate batter visible.

7. Use a butter knife to swirl the batters together.

8. Freeze for several hours until the fudge is firm and the parchment paper peels off cleanly.

9. Cut the fudge into squares. Store in the freezer and enjoy as needed.

Ingredient Substitutions

Casein or a whey/casein blend can sub for the whey protein powders, but you'll likely need to increase the water slightly.

Replace almond butter with cashew butter for a different nutty flavor.

Use honey or maple syrup instead of agave nectar.

Recipe Variations

Add crushed sugar-free peppermint candies for a crunchy texture.
Sprinkle sea salt flakes on top for a sweet-and-salty combination.
Use white chocolate whey protein powder for a different twist on the peppermint layer.

Storage Info

Store the fudge in a parchment-lined airtight container in the freezer. It will keep well for about a month.

Allow the fudge to thaw slightly at room temperature for a few minutes before eating for the best texture.

FAQ

Can I use a different type of protein powder?

This recipe works best with whey protein powder. Casein or a whey/casein blend can also be used, but plant-based powders are not recommended.

Can I double the recipe? What size pan should I use?

Yes, you can double the recipe and use a square 8"x8" pan.

How long does the fudge take to freeze?

It typically takes 4-6 hours to freeze completely. If you'd like it to be ready sooner, split it up into smaller (metal or glass) loaf pans.

Can I use a different nut butter?

Cashew butter would be a good choice to replace the almond butter.

What if the batters are too thick?

Add a small amount of water, one teaspoon at a time, until the texture improves.

Enjoy this Peppermint Swirl Protein Fudge as a festive, protein-packed treat that satisfies your sweet tooth while supporting your health goals.
