Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Peanut Butter.
I prefer natural, unsweetened peanut butter. It gives a creamy base and rich flavor while keeping things keto-friendly.

Protein Powder.
A good-quality protein powder adds structure and boosts protein content. Vanilla or unflavored works best.

Sugar-Free Chocolate.
This creates the outer shell. It hardens nicely in the freezer and keeps the recipe low-carb.

Coconut Oil.
Helps smooth the chocolate and makes it easier to coat. It also gives a slight melt-in-your-mouth texture.

Low-Carb Sweetener.
Adds just the right touch of sweetness without increasing carbs. Adjust based on taste preference.

How to Make This Recipe

Start by mixing your peanut butter filling until it’s thick and creamy—this is your base. Shape it into small bite-sized pieces, then chill them so they hold together nicely.

Next, melt your chocolate until smooth and glossy. Dip each frozen piece carefully, letting excess drip off, then place them back on the tray.

Finally, freeze again until the chocolate sets firm. You’ll know they’re ready when the shell is solid and slightly shiny, with a creamy center when you bite in.

Storage Instructions

Store these peanut butter cups in an airtight container in the refrigerator for up to 1 week. For longer storage, keep them in the freezer for up to 2 months.

Use freezer-safe containers or zip bags to prevent freezer burn. Let them sit at room temperature for 1–2 minutes before eating for the best texture.
