These Dark Chocolate Peanut Butter Cups are a sweet treat that hits the spot! With creamy peanut butter wrapped in rich dark chocolate, they’re simply heavenly!
Key Ingredients & Substitutions
Dark Chocolate: I recommend using chocolate that is 70% cocoa or higher. The richer, more intense flavor pairs beautifully with the peanut butter. If you’re not a fan of dark chocolate, semi-sweet chocolate can work as a milder substitute.
Peanut Butter: Creamy peanut butter is great for this recipe, but feel free to use crunchy if you like some texture. For nut-free options, almond butter or sunflower seed butter can be tasty alternatives.
Coconut Oil: This is optional but helps achieve a smoother peanut butter filling. If you don’t have it, unsalted butter works well too. For a dairy-free option, just stick with the coconut oil.
Powdered Sugar: This sweetens the peanut butter and helps improve the texture. If you’re looking for a healthier option, you could substitute it with maple syrup, adjusting the amount to taste.
Sea Salt: A sprinkle on top is a must! It enhances the chocolate and peanut butter flavors. If you don’t have sea salt, regular salt works, but keep it light.
How Do I Get the Chocolate to Set Perfectly?
Getting the chocolate to set right is key to a good bite. Start by melting your chocolate properly to avoid seizing it.
- For melting chocolate, a double boiler is best. If using a microwave, heat in 30-second bursts, stirring between each, until smooth.
- When you spoon melted chocolate into the cups, let it rise slightly up the sides. It helps make a well for the filling.
- Let the first layer of chocolate set in the freezer for about 10 minutes. This ensures it hardens enough to hold the filling when you add it.
- Cover the filling carefully with more melted chocolate, making sure to completely seal it so the peanut butter doesn’t leak out.
- For the best results, let the cups set in the freezer or fridge for a full 20-30 minutes before removing them from the liners.
With these simple tips, your peanut butter cups will turn out deliciously! Enjoy making these treats!

How to Make Dark Chocolate Peanut Butter Cups
Ingredients You’ll Need:
- 1 1/2 cups dark chocolate chips or chopped dark chocolate (70% cocoa or higher)
- 1/2 cup creamy peanut butter (natural or regular)
- 2 tablespoons powdered sugar
- 1 tablespoon coconut oil or unsalted butter (optional, for smoother filling)
- 1/4 teaspoon vanilla extract (optional)
- Sea salt flakes, for sprinkling on top
How Much Time Will You Need?
This recipe takes about 15-20 minutes of prep time. You’ll need an additional 30 minutes to chill in the fridge or freezer to let the cups set properly. In total, you’re looking at about 45-50 minutes before you can enjoy these delicious treats!
Step-by-Step Instructions:
1. Prepare Your Muffin Tin:
Start by lining a muffin tin or a tray with cupcake liners. This will make it easy to remove the cups once they are set and gives them a nice presentation.
2. Melt the Chocolate:
Next, melt the dark chocolate chips using a double boiler. If you’re using a microwave, heat the chocolate in 30-second intervals, stirring in between, until it’s smooth and fully melted.
3. Create the Chocolate Base:
Spoon about 1 tablespoon of melted chocolate into each liner. Use the back of the spoon to spread the chocolate evenly on the bottom and slightly up the sides. Then, place the tray in the freezer for about 10 minutes to let the chocolate set.
4. Mix the Peanut Butter Filling:
While the chocolate is hardening, prepare the peanut butter filling. In a bowl, mix together the creamy peanut butter, powdered sugar, coconut oil, and vanilla extract until everything is well combined and smooth.
5. Fill the Cups:
Once the chocolate-lined cups have set, take them out of the freezer. Add about 1 tablespoon of the peanut butter filling to the center of each cup. Gently press it down to flatten it slightly, but be sure to leave some space around the edges for sealing.
6. Add the Final Chocolate Layer:
Using the remaining melted chocolate, cover the peanut butter filling by adding about another tablespoon on top. Spread gently to seal the edges and smooth the tops.
7. Salt It Up:
Sprinkle a pinch of sea salt flakes on top of each cup. This little touch enhances the flavors and makes each bite even more delicious!
8. Chill to Set:
Return the cups to the freezer or fridge and let them set completely, which should take about 20-30 minutes. They need to harden fully before you can enjoy them.
9. Enjoy Your Treat!
Once the cups are hardened, remove them from the liners and store them in an airtight container in the fridge. These Dark Chocolate Peanut Butter Cups are now ready to be savored!
Enjoy the perfect balance of rich dark chocolate and creamy peanut butter in every bite!
Can I Use Milk Chocolate Instead of Dark Chocolate?
Yes, you can! If you prefer a sweeter taste, feel free to substitute dark chocolate with milk chocolate. Just keep in mind that the flavor profile will change, becoming milder and sweeter.
How Do I Store These Peanut Butter Cups?
Store any leftover peanut butter cups in an airtight container in the fridge. They will stay fresh for up to a week, but I doubt they’ll last that long!
Can I Make Them Vegan?
Absolutely! Use dairy-free dark chocolate and replace the regular peanut butter with a vegan option. You can also omit the coconut oil for a fully plant-based treat.
What If My Chocolate Seizes While Melting?
If your chocolate seizes, it usually means it got too hot or came into contact with water. Don’t panic! You can try salvaging it by adding a teaspoon of coconut oil or vegetable oil and stirring until smooth again!
