Your Shopping Guide

When preparing to make your Keto Peanut Butter Cups (like Reese’s), you’ll want to gather the following ingredients:
- Chocolate: 4 oz (110g) sugar-free chocolate chips or 90% dark chocolate.
- Coconut Oil: 1 tablespoon for added creaminess and texture.
- Peanut Butter: 1 cup (65g) of smooth peanut butter is essential for that creamy filling.
- Allulose (optional): 1 teaspoon to 1 tablespoon if you prefer extra sweetness.
- Salt: 1/2 teaspoon only if your peanut butter doesn’t already contain salt.
Tools of the Trade

Before diving into the kitchen, make sure you have these essential tools:
- Microwave-Safe Bowl: For melting the chocolate and coconut oil together.
- Silicone Muffin Cups: Perfect for creating the cups without sticking.
- Mixing Spoon: For stirring the peanut butter and sweetener mixture.
- Freezer or Refrigerator: You’ll need space for the cups to set.
Cooking Keto Peanut Butter Cups (like Reese’s): The Process
Step 1: Prepare Your Muffin Cups
Start by placing your silicone muffin cups on a baking sheet. This will make them easier to handle when they are filled with the mixture.
Step 2: Melt the Chocolate
In a microwave-safe bowl, combine the sugar-free chocolate chips or dark chocolate with the coconut oil. Heat in the microwave in 30-second intervals, stirring in between until completely melted and smooth.
Step 3: Create the Chocolate Base
Spoon a small amount of the melted chocolate into the bottom of each silicone cup. Use the back of a spoon to spread it evenly across the bottom. Place the cups in the freezer for about 5 minutes to set.
Step 4: Make the Peanut Butter Filling
In a mixing bowl, combine the smooth peanut butter and optional allulose. If your peanut butter is unsalted, add salt to taste. Mix until well combined and creamy.
Step 5: Add the Peanut Butter Layer
Once the chocolate base is set, remove the cups from the freezer. Spoon the peanut butter mixture on top of the chocolate base, filling each cup about 3/4 full.
Step 6: Seal with More Chocolate
Pour the remaining melted chocolate over the peanut butter layer in each cup. Use a spoon to spread it evenly and cover the peanut butter completely.
Step 7: Final Chill
Return the cups to the freezer for another 10-15 minutes until they are completely firm. Once set, you can pop them out of the silicone cups.
Seasonal Twists
If you’re looking to give your Keto Peanut Butter Cups (like Reese’s) a seasonal twist, consider these ideas:
- Pumpkin Spice: Add a teaspoon of pumpkin spice to the peanut butter mixture for a fall-inspired treat.
- Mint Chocolate: Mix in a few drops of peppermint extract into the peanut butter or chocolate for a refreshing minty flavor.
- Coconut: Stir in shredded unsweetened coconut into the peanut butter mixture for a tropical flair.
- Protein Boost: Incorporate your favorite protein powder into the peanut butter for an extra nutritious kick.
Things That Go Wrong
While making Keto Peanut Butter Cups (like Reese’s) is quite simple, a few common mistakes can occur:
- Chocolate Seizing: If you overheat the chocolate, it can become grainy. Always heat in short intervals and stir well.
- Peanut Butter Too Thick: If your peanut butter is too thick, consider adding a little coconut oil or almond milk to loosen it up.
- Not Setting Properly: Ensure you give enough time for both the chocolate base and the cups to set in the freezer.
- Using the Wrong Peanut Butter: Make sure to use smooth peanut butter for the best texture and consistency.
Prep Ahead & Store
To enjoy your Keto Peanut Butter Cups (like Reese’s) longer, here are some tips for prepping and storing:
- Make Ahead: These cups can be made in advance and stored in the refrigerator for up to two weeks.
- Freezing: For longer storage, keep them in the freezer in an airtight container. They can last for up to a month.
- Thawing: When ready to eat, simply allow them to thaw at room temperature for a few minutes.
Quick Q&A
Can I use crunchy peanut butter instead of smooth?
Yes, you can use crunchy peanut butter, but keep in mind it will alter the texture of your cups, adding a delightful crunch.
What can I substitute for coconut oil?
You can use unsalted butter or ghee as an alternative to coconut oil, although it may slightly change the flavor.
Are these cups kid-friendly?
Absolutely! These Keto Peanut Butter Cups (like Reese’s) are a great option for kids who enjoy peanut butter and chocolate, plus they are healthier than standard candies.
Can I use a different sweetener?
Sure! Feel free to use your preferred keto-friendly sweetener, such as erythritol or monk fruit, in place of allulose.
