Peanut butter cup brownies are delicious fudgy brownies with just the right amount of peanut butter. If you like the blend of peanut butter and chocolate, these are perfect for you. I used regular Reese’s peanut butter cups. But you can use a different brand if you prefer. Or you can use miniature peanut butter cups.
Peanut butter brownies are so delicious you’ll want to make them for any special occasion. You’ll appreciate the fact that this is such an easy recipe. In fact, if you like peanut butter, it might become your absolute favorite brownie recipe.
One of the things I love about them is that they’re easy to make, and so many people love them. This is the perfect dessert to serve after a meal of your favorite comfort food.
Reese’s Cup Brownies
Peanut butter lovers will appreciate these delicious Reese’s cup brownies. In fact, they are some of the best brownies I make. You can make them from scratch, but I prefer using a box of brownie mix.
I also make this chocolate peanut butter moose munch with some Reese’s cups in the mix. It’s so fun to eat, and it’s always a hit at parties!
Ingredients for Peanut Butter Cup Brownies
You can either start with your own homemade brownie batter or use a mix. Since this is so doctored up, I used a boxed brownie mix.
Here’s what you’ll need to make these delicious specialty brownies:
- Box of brownie mix (regular or gluten-free)
- Melted butter
- Peanut butter cups
Since I have to be gluten-free, I take whatever is on the shelf. However, if you can eat the regular brownies, pick your favorite mix. Mine would be fudge brownie mix or dark chocolate brownie mix.
Keep in mind that my brownie mix requires melted butter, eggs, and water. Yours may have something else listed, such as vegetable oil. Use whatever the mix calls for.
I used salted butter. However, you can use unsalted butter and get great results.
For exact measurements of each ingredient and full directions for the mix I use, go to the recipe card at the bottom of the page. You can even print out the card by using the “print” button.
Heat oven to 350 degrees F. That way, Doing this gives it time to get hot enough to bake the brownies.
Spray your baking pan with nonstick spray. Choose a pan based on how thick or thin you want your brownies. I like them average thickness, so I used a 7” x 11” rectangular baking pan. You can also use an 8” x 8” square baking pan. For thicker brownies, try a loaf pan.
You can also make peanut butter cup brownies in a muffin tin. Since the muffin cups are much smaller, you’ll need to decrease the baking time by 5 to 10 minutes. Check the recommendations on your box of mix.
How to Make Peanut Butter Cup Brownies
In a large bowl, prepare the brownie batter as directed on the back of the package. Stir all of the ingredients until the batter is smooth and silky.
Pour 1/3 of the brownie batter into the bottom of the prepared pan.
Smooth it out as much as you can.
Place 12 of the whole peanut butter cups into the batter in a single layer. Space them out as evenly as possible.
They don’t have to be perfect, but you want all of the brownies to have some of the peanut butter cup in them.
Next, pour the remaining batter over the top. Smooth it out, being careful to keep the peanut butter cups in place.
They have a tendency to move around, so keep nudging them back into position. Cover the tops of the peanut butter cups.
In a small bowl or plate, chop the remaining 4 peanut butter cups into small pieces.
Scatter all of them over the top of the batter. Gently press them down.
Put the pan in the preheated oven and bake for 30 minutes. To test them, stick a toothpick into the brownies and pull it out. They’re done when there’s no wet batter on the toothpick … only moist crumbs.
Set the pan on a wire rack and allow the brownies to cool for 30 to 45 minutes. They’re best at room temperature. Cut them into squares or rectangles.
Peanut Butter Cup Brownie Add-Ons
These brownies are delicious as-is. The blend of melted chocolate and peanut butter from the candy inside and on top of the traditional brownies will satisfy any sweet tooth.
However, if you want to kick up your brownie game another notch, try a few of these add-ons to make them even better:
- Chocolate chips
- Vanilla extract
- Unsweetened cocoa powder
- Chocolate chips or chopped chocolate
- Brown sugar
- Peanut butter frosting
- Extra peanut butter cups
You can also finish off these brownies by drizzling some melted peanut butter over the top and running your knife through it to make a peanut butter swirl.
How to Keep Peanut Butter Cup Brownies
These brownies are good for a couple of days at room temperature as long as you store them in an airtight container.
You can also cover them in plastic wrap and store them in the freezer for 2 to 3 months. Whenever you’re in the mood for a chocolate treat, remove one or two brownies from the freezer and let it thaw.
