Step‑by‑Step Instructions for Keto Peanut Butter Cups
Step 1: Prepare the Muffin Tin
Begin by preparing a 12-count muffin tin, lining each cup with muffin liners or generously greasing them with cooking spray. This will ensure easy removal of your homemade Keto Peanut Butter Cups once they’re set. Set the tin aside while you move on to melting the chocolate mixture.
Step 2: Melt the Chocolate
In a microwave-safe bowl or a double boiler, combine your keto chocolate chips and coconut oil. Heat the mixture in 30-second intervals, stirring frequently until it becomes velvety smooth. This should take about 1-2 minutes in total. The beautiful gloss of your melted chocolate is exactly what you’re looking for.
Step 3: Coat the Muffin Liners
Once your chocolate is melted and luscious, take a spoon and fill each muffin liner about a third full. Use the back of the spoon to gently spread the chocolate up the sides, creating a cup shape. This will be the base of your Keto Peanut Butter Cups, and it should start to set slightly as it cools.
Step 4: Add the Peanut Butter Filling
Next, take your smooth and drippy peanut butter and add a generous tablespoon into the center of each chocolate-filled liner. It should sit nicely atop the chocolate base, ready to be tucked in for a delicious surprise. Make sure to leave some space around the edges for the final layer of chocolate.
Step 5: Top with More Chocolate
Now, return to your melted chocolate and pour a bit more over the peanut butter filling in each cup, ensuring it covers the peanut butter completely. This step seals in the goodness while forming a delightful outer layer. Make sure each cup is well coated for a satisfying bite!
Step 6: Chill to Set
Place the muffin tin in the refrigerator and let your Keto Peanut Butter Cups chill for at least 1 hour. This will allow the chocolate to harden and set perfectly around the creamy peanut butter filling. You’ll know they’re ready when the chocolate appears firm and shiny.
Step 7: Optional Flavor Boost
For an extra touch of flavor, you can sprinkle a pinch of sea salt over the top of each cup just before chilling. This addition enhances the rich taste of the Keto Peanut Butter Cups and balances the sweetness beautifully, adding a gourmet touch to your homemade treats.

Keto Peanut Butter Cups Recipe FAQs
How do I choose the best ingredients for Keto Peanut Butter Cups?
Absolutely! When selecting keto chocolate, opt for high-quality brands with a higher cacao content (70% or above) and minimal sugar. For peanut butter, look for natural varieties that list peanuts as the first ingredient, avoiding added sugars and oils. This ensures a richer flavor and a healthier treat that stays in line with your keto goals.
What’s the best way to store Keto Peanut Butter Cups?
You can store your Keto Peanut Butter Cups in an airtight container at room temperature for up to 1 month. For longer freshness, keep them refrigerated for up to 3 months. If you choose to freeze them, lay them in a single layer on a baking sheet first and transfer them to a freezer-safe bag after about 2 hours. They can be kept in the freezer for up to 6 months!
Can I make Keto Peanut Butter Cups ahead of time?
Very! You can prepare the chocolate mixture and fill the muffin liners up to 24 hours in advance. Simply let them set as directed and then add the peanut butter topping right before you plan to serve. This is a great option for party prep or to quench those late-night cravings, ensuring they're ready when you are!
What should I do if my chocolate mixture is too thick?
No worries! If your chocolate mixture seems too thick after melting, simply add an additional tablespoon of coconut oil and reheat gently in 15-second increments, stirring constantly. This will help achieve a smooth, pourable consistency. Just remember to not overheat, as it can affect the texture of your cups!
Can my pets have Keto Peanut Butter Cups?
It’s important to note that while peanut butter is often safe for dogs in moderation, it should never contain xylitol, a common sugar substitute that is toxic to pets. Always check labels. Chocolate, however, is harmful to both dogs and cats, so it's best to keep these enticing treats safely out of their reach!
Are there any common allergies I should consider with this recipe?
Definitely! Beyond chocolate and coconut allergies, the predominant ingredient here is peanuts—one of the top allergens. Always ensure that guests are aware of what's in these cups when serving them, especially if you're making them for gatherings. Adjustments can be made by substituting with allergy-friendly sunflower seed or almond butter if needed!
