Peanut Butter Brownies Ingredients
If you’re a consistent baker like me, you’ll probably have more of these staple items in your fridge and pantry. The only thing I usually don’t have on hand is the mini peanut butter cups because I mean honestly, who can resist those little guys? The question is, who gets to them first, me or my kids?
So, to make this recipe from scratch you’ll need the following:
- 3 tablespoons of butter
- 2 tablespoons of milk
- ½ a cup of sugar
- 1 ½ cups of chocolate chips
- 2 eggs
- 1 teaspoon of vanilla
- ½ cup plus 2 tablespoons of flour
- ¼ teaspoon of baking soda
- ¼ teaspoon salt
- ½ cup of chopped mini peanut butter cups
- ½ cup of peanut butter
I always use natural peanut butter in my kitchen, but any type of peanut butter will work fine for this recipe!
If you want to make these peanut butter brownies using a brownie mix, see the directions below!
How To Make Peanut Butter Brownies
First, you’re going to want to get everything set up.
I like to measure out my ingredients and prep my baking pans, etc. before I actually start baking.
So, preheat your oven to 350 degrees, line an 8×8 baking pan with foil, parchment paper or a silicone baking mat and make sure you have your ingredients measured out and set aside so you can fly through the next steps!
In a medium bowl, stir together your butter, milk, and sugar over medium heat until it just starts to boil. Remove from heat as soon as it starts!
Then, stir in your chocolate chips until it is all smooth and melted.
Set this mixture aside and let it cool down for about 5 minutes.
When it’s cooled, whisk in your eggs and vanilla.
Stir in the ½ cup of flour, salt, and baking soda until it is just combined.
In a separate small bowl, toss in your chopped mini peanut butter cup pieces and the remaining 2 tablespoons of flour.
Fold the peanut butter mixture into the batter.
Then, pour the brownie batter into your lined baking dish.
Take a small spoon, or cookie scoop, and put dollops of peanut butter on top of the brownie batter. Next, use a butter knife to swirl the peanut butter through the top of the batter.
Doesn’t it look delicious?
Okay, now it’s ready to go into the oven!
Bake for about 30 minutes, use the toothpick method to make sure it’d done. (Toothpick method is when you have the toothpick inserted and when you pull it out, it’s clean!)
When they are ready, take them out of the oven and let them cool completely before slicing.
For the best fudgy brownie taste, serve when they are still warm, and add a scoop of vanilla ice cream and drizzle chocolate sauce over everything!
