Chocolate + Peanut Butter = The Best Kind of Dessert!

When you think of love, what do you think of? Hearts? Candy? Kisses? Or if you’re like me…CHOCOLATE!

I love, love, LOVE chocolate.

I love chocolate so much that my mom told me that as a baby I wouldn’t drink white milk so she added a little…you guessed it…Hershey’s Syrup to my bottle! haha! I have no idea why I have this addiction, er…I mean, love of chocolate!

As a matter of fact, I told my husband today that I loved him MORE THAN chocolate. And, he took it as a compliment because he knows just how much I love the dark, creamy, sweet stuff.

And these Peanut Butter Cup Brownies rank right up there with my all-time favorite desserts!

So, when looking at my favorite inspiration site, Pinterest, when deciding what to make for dessert for dinner with friends last week, I knew that I had to make these yummy Peanut Butter Cup Brownies I’ve been eyeing lately.

And, I’ve got to tell ya…they were worth every. single. calorie.

The recipe I found called for you to make your own homemade brownie mix for these, but I used my favorite go-to boxed brownie mix instead.

Ingredients + Variations

Here’s what you’ll need to make these mini Peanut Butter Brownies:

  • Boxed brownie mix – Use your favorite variety!
  • Peanut butter – Again, use whatever you like best, whether it’s smooth and creamy, natural, or chunky.
  • Semi-sweet chocolate chips – You could swap in mini chocolate chips or milk chocolate chips, too.
  • Peanut butter morsels – Or double the amount of chocolate chips. It’s up to you!

Since this Peanut Butter Brownie recipe is one of my faves, I have a bunch of variations to share with you if you want to mix things up a bit. Try:

  • Using chopped peanuts instead of or in addition to the peanut butter morsels
  • Melting some chocolate chips, then drizzling the chocolate over the tops of the brownies once they’ve cooled
  • Chopping some mini Reese’s peanut butter cups and using those as a topping instead of the chips
  • Using mini Reese’s Pieces as a topping
  • Dusting the brownies with powdered sugar

How to Make Mini Peanut Butter Cup Brownies

1. Prepare

Preheat the oven to 350ºF and grease a 12-cup muffin tin.

2. Make the Brownies

Follow the instructions on the boxed brownie mix and make the brownie batter. Divide the batter into the 12 muffin cups, then bake for about 20 minutes, or until a toothpick inserted into the center comes out mostly clean, with only a few crumbs sticking to it.

3. Add the Peanut Butter

Let the brownies cool for a few minutes, then press the back of a spoon into the centers to create an indentation. Warm the peanut butter in the microwave until it’s smooth, then spoon a small amount into each indentation.

4. Top the Brownies

Sprinkle the chocolate chips and peanut butter chips over the tops of the brownies, then allow them to cool completely.

FAQ

How do you store Peanut Butter Brownies?

Store your brownies in an airtight container at room temperature. They’ll last for about 3 days, although you’ll probably eat them way before that!

Should I make the recipe for fudgy brownies or cake brownies on the package?

If your boxed brownie mix has recipes for cake brownies and fudgy brownies on the back, go with the fudgy recipe. It’s better for holding the peanut butter!

      I’ve not frozen them but I think it would work well! Just allow to come to room temp on the counter.
