Step-by-Step Directions
Now, let’s get into how to make these keto peanut butter cups at home. The process is simple and doesn’t require any fancy kitchen tools—just a microwave and a mixing bowl.
- Mix the Filling Ingredients: Start by adding powdered sweetener, non-dairy milk, vanilla extract, peanut butter, and coconut oil to a bowl. Blend them until they form a smooth dough-like consistency. If needed, adjust the salt for taste.
- Prepare the Chocolate: In a microwave-safe bowl, melt the sugar-free milk chocolate and white chocolate chips. Do this in 15-second intervals, stirring between each until fully melted and smooth.
- Line the Cupcake Tin: Take a cupcake tin and line it with paper cupcake liners. This will help you easily remove the keto peanut butter cups once they’re ready.
- Assemble the Cups: Add a tablespoon of melted chocolate to the bottom of each liner. Then, take a small amount of the peanut butter mixture and shape it into a flat, round disc. Place the peanut butter disc on top of the chocolate layer in each cup.
- Add the Chocolate Top Layer: Pour another tablespoon of melted chocolate over the peanut butter disc, making sure to completely cover it.
- Set and Chill: Once all the cups are assembled, place the tray in the freezer or fridge to set. This should take about 20-30 minutes.
- Enjoy: Once the chocolate has hardened, your keto peanut butter cups are ready to enjoy! They store well in the fridge for up to a week, so you can keep a stash on hand for whenever a sweet craving hits.

Why Keto Peanut Butter Cups Are the Perfect Snack

Tips for Perfect Keto Peanut Butter Cups
- Choose the Right Sweetener: Using a powdered sweetener is important because it blends smoothly into the peanut butter mixture without leaving a gritty texture. If you only have granular sweetener, you can blend it in a food processor to make it powdered.
- Avoid Burning the Chocolate: When melting chocolate in the microwave, heat it in short intervals and stir often to prevent it from burning. Chocolate can quickly overheat, especially when it’s sugar-free, so take your time with this step.
- Get Creative with Flavors: While the classic peanut butter filling is a winner, you can switch it up by using almond butter or coconut butter if you have nut allergies or just want a different flavor profile.
