Recipe ingredients
There are only a few ingredients in these dark chocolate peanut butter cups (flaky sea salt is optional but recommended).
- Dark chocolate chips (about 1.5 cups). Dark chocolate brings depth and reduces overall sweetness. Use your favorite variety or any chocolate you prefer.
- Peanut butter (1/2 cup). Creamy or crunchy both work. Swap with almond or sunflower seed butter for allergies or preferences.
- Protein powder (1/3 cup). Vanilla or unflavored protein powder works well. Different protein types (whey, plant, collagen) will affect texture slightly.
- Honey (2 tablespoons). Adds subtle sweetness and helps bind the filling; maple syrup is an easy substitute.
- Coconut oil (1 tablespoon). Thins the melted chocolate so it’s easy to pour and softens the finished shell. Melted butter can be used instead.
- Flaky sea salt. Optional, but a small sprinkle on top enhances flavor and balances sweetness.

How to make homemade peanut butter cups
These peanut butter cups are very simple to prepare and are a fun, no-bake project. Assembly takes about 10–15 minutes; most of the total time is chilling.
Pro tip: Vanilla whey or a mild-flavored plant protein blends nicely with the peanut butter. Avoid overly chalky powders for the best mouthfeel.

Recipe FAQs
Whey, collagen, and most plant-based protein powders will work. Vanilla or unflavored varieties blend best with the peanut butter. Keep in mind texture varies by type—choose a powder you know has a pleasant mouthfeel.
Protein powder helps firm the filling. Without it the filling will be soft; you can thicken it with a tablespoon or two of almond flour or coconut flour if you prefer to omit protein powder.
Coconut oil thins and softens the chocolate so it’s easy to bite through. Melted butter is a fine substitute if you don’t have coconut oil.
Store in an airtight container in the refrigerator for up to 2 weeks. For longer storage, freeze for up to 3 months and thaw at room temperature a few minutes before serving.
Recipe notes
- Pro tip: Different protein powders will produce different textures; vanilla or neutral flavors mix most seamlessly with peanut butter.

Protein Peanut Butter Cups
12 servings
Equipment
- Standard muffin pan
- Paper or foil liners
Ingredients
- 1/2 cup creamy peanut butter
- 1/3 cup protein powder (vanilla or unflavored)
- 2 tablespoons honey (or maple syrup)
- 1.5 cups dark chocolate chips (about 9 ounces)
- 1 tablespoon melted coconut oil (or butter)
- Flaky sea salt, for sprinkling (optional)
Instructions
- Place 12 paper or foil liners in a standard muffin tin.
- In a medium bowl, stir together peanut butter, protein powder, and honey until smooth and lump-free. The mixture will form a soft dough.
- Form the mixture into 12 flattened discs (about 1 tablespoon each) and set aside.

- Spoon about 1 tablespoon melted chocolate into each paper-lined muffin cup and spread slightly up the sides. Place a peanut butter disc over the chocolate in each cup, then drizzle about 1/2 tablespoon more chocolate over the top to cover the filling. Sprinkle with flaky sea salt, if desired.
- Chill in the refrigerator for up to 3 hours or until set. Remove from liners and enjoy. Store refrigerated or freeze for longer storage.
Notes
- Protein tip: Using a vanilla or mild protein powder gives the best flavor. Textures will vary by protein type.
