Avoid using a dark-colored muffin tin if you can. Dark pans conduct heat more aggressively and can cause the bottoms and edges to brown too quickly, potentially burning before the center is done. A lighter-colored or aluminum pan gives you the most even bake. If you only have a dark pan, reduce the oven temperature by 25 degrees.
Don’t press the peanut butter cup all the way to the bottom of the tin. You want it suspended in the middle of the cookie dough. If it touches the hot metal, the chocolate can scorch and give a bitter taste. The goal is to have a layer of baked cookie both under and over the candy.
Finally, don’t substitute with other chocolate candies without adjusting bake time. I tried it with a solid milk chocolate bar piece, and it melted into an oily pool. Peanut butter cups have a firm, stable structure that softens perfectly without disintegrating. If you must experiment, use something with a similar composition, like a peanut butter-filled milk chocolate kiss.
Serving Suggestions
I love serving these warm, when the peanut butter cup center is at its peak gooiness, with a small scoop of vanilla ice cream on the side. The contrast of temperatures is heavenly. A drizzle of extra melted peanut butter or chocolate sauce takes it over the top for a real dessert experience.
For a casual treat, I let them cool completely and pack them in lunchboxes or serve them as an after-school snack with a tall glass of cold milk. They are sturdy enough to travel but still satisfyingly soft and rich. They’re always met with excited smiles.
These are also a fantastic, easy contribution to a potluck or bake sale. Just place them in a cupcake liner in a festive container. They look adorable and are instantly recognizable as a crowd-pleasing favorite. I always bring the recipe with me because I’m always asked for it.
Variations & Customizations
For a chocolate-peanut butter overload, use chocolate chip cookie dough instead of plain peanut butter dough. The result is like a deep-dish chocolate chip cookie with a molten peanut butter cup core. It’s incredibly rich and a hit with anyone who loves that classic combo.
Try using different peanut butter cup varieties! The white chocolate Reese’s cups are fantastic, and the dark chocolate ones add a more sophisticated, less sweet bitterness that’s wonderful. You can even use the seasonal shapes, like the Halloween pumpkins or Christmas trees, for a festive touch.
Add a sprinkle of flaky sea salt on top of each cookie cup immediately after they come out of the oven the second time. The salt amplifies the peanut butter flavor and cuts through the sweetness perfectly. A handful of chopped peanuts pressed into the dough before baking adds a wonderful crunch.
How to Store, Freeze & Reheat
Store completely cooled cookie cups in an airtight container at room temperature for up to 4 days. They will soften over time but remain delicious. If your kitchen is very warm, you can refrigerate them to keep the chocolate center firm.
You can freeze these for up to 3 months. Wrap each cooled cookie cup individually in plastic wrap, then place them in a freezer bag. Thaw at room temperature for a couple of hours or overnight in the fridge.
To reheat and restore that fresh-baked, melty-center magic, place a room-temperature or thawed cookie cup on a microwave-safe plate and microwave for 8-12 seconds. Just until it’s warm to the touch. Be careful—overheating will make the chocolate scorch. You can also warm them in a 300°F oven for 5-7 minutes.
