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 Browniesrank right up there with my all-time favorite desserts!

So, when looking at my favorite inspiration site, Pinterest, whendecidingwhatto 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!

One change is to use milk or heavy cream instead of water. This change will make brownies more moist and gooey since milk is more fatty and flavorful than water.

Crushed potato chips, pretzels, and salted nuts stirred in or sprinkled on before baking can add textural interest, plus a little savoriness that can make the rich chocolate flavor more pronounced.

What does adding an extra egg to brownie mix do? ›

If you opt to add more eggs, say double the amount, something interesting happens. Even though you are adding more moisture, the air bubbles that you catch in the extra eggs add volume, which decreases the density of your final product. This makes your brownies rise and gives them a much more cake-like texture.

What can you add to brownies to make them better? ›

Fruits and nuts are great for introducing more flavor and texture to your brownies. When it comes to nuts, you can reach for whatever you have in your pantry—salted, candied, or otherwise. “When I make brownies or blondies, I like to add toasted nuts for extra crunch and flavor,” says culinary editor Genevieve Yam.

How to make boxed brownie mix better? ›

Can I use milk instead of water in brownie mix? ›

What happens if you add flour to brownie mix? ›

If you think about the main characteristic that stands out in a cake, it is probably its fluffy texture. Therefore, to get this extra volume, you want to have more little flour granules in your batter, all swelling together.

Does letting brownie batter sit make it better? ›

Alice Medrich, author of Seriously Bitter Sweet: The Ultimate Dessert Maker's Guide to Chocolate, writes that “refrigerating the brownie batter in the pan for several hours, or as long as two days before baking, wreaks enormous transformations: it improves the top gloss and crustiness, and it also blends the flavors so ...

Can you combine 2 boxes of brownie mix? ›

Happy baking! Heat oven to 325°. Grease bottom of 13x9x2-inch rectangular pan. Prepare batter using 2 packages any Betty Crocker®Premium brownie mix, double all ingredients for the water, oil and eggs called for on the package directions.

Can you skip eggs in brownies? ›

Is it okay to make brownies without eggs? Without eggs, baked goods will become a little thinner and not rise as much in the oven. As long as you replace the moisture from the egg with milk, banana or applesauce, you can make brownies without eggs. And yes, this recipe makes thinner brownies than normal.

Are brownies junk food? ›

Brownies, like many baked goods, can be classified as junk food due to their high sugar and fat content, as well as the use of refined flour. These ingredients contribute to a high calorie content and a lack of essential nutrients.

Do brownies taste better with milk or water? ›

Brownie recipes traditionally call for water as it serves as a neutral liquid that hydrates the dry ingredients. However, using milk instead of water can impart a creamier texture and richer flavor to your brownies. The milk's fat content adds a smoothness that water cannot provide, resulting in a more indulgent treat.

How do you improve boxed brownie mix? ›

Add Salt. If you've ever found boxed brownies to be too sweet for your taste, stir a pinch of salt into the batter before baking. This'll help bring out the deeper chocolate flavors. You can even try sprinkling some flaky sea salt on top of the brownies as soon as they come out of the oven.

How do you make store bought brownie mix better? ›

Adding coffee to your brownies boosts their flavor because its bitter quality balances out sweetness, making it less overpowering. It allows that delicious chocolate flavor to really shine.

What happens when you add milk to brownie mix? ›

Brownie recipes traditionally call for water as it serves as a neutral liquid that hydrates the dry ingredients. However, using milk instead of water can impart a creamier texture and richer flavor to your brownies.

Can I use butter instead of oil in brownie mix? ›

You can absolutely substitute butter for the vegetable oil. Use the same quantity specified in the directions (for example, if it calls for 1/3 cup of oil, use 5 1/3 tablespoons of butter). Melt it down, then let it cool a bit. You might not ever go back to oil!
