Ingredients

1½ cups milk chocolate chips
3 tablespoons vegetable oil
½ cup granulated sugar
½ cup all-purpose flour
¼ teaspoon baking soda
¼ teaspoon salt
2 eggs, room temperature
1 teaspoon vanilla extract
2 tablespoons whole milk
½ cup peanut butter cups, chopped
1 tablespoon all-purpose flour
½ cup creamy peanut butter

Instructions

Preheat the oven to 350°F. Line an 8x8-inch nonstick baking dish with parchment paper and set it aside.
In a heat-safe small bowl, add the chocolate chips and the oil. Microwave for 45 seconds. Stir the chips and oil, return to the microwave, and heat for another 10 seconds. Stir until the chips and oil are smooth. Set it aside.
Using a medium-sized mixing bowl whisk together all-purpose flour, granulated sugar, baking soda, and salt. Set it aside.
In a small bowl, whisk together the eggs, vanilla extract, and milk. Add to the flour mixture. Now add the melted chips and stir until the batter is just combined.
Toss the chopped peanut butter cups with 1 tablespoon of flour. Fold the coated chopped peanut butter cups into the batter and mix just until all ingredients are combined.
Pour the batter into the prepared baking dish.
Using a 1 to 1½ tablespoon cookie scoop or a regular tablespoon, dollop the peanut butter on top of the brownie batter. Use a knife to swirl the peanut butter.
Bake for 30 minutes.
Allow the brownies to cool completely before cutting.

Notes

Refrigerating peanut butter cups for 10 minutes makes them much easier to chop.
Tossing the peanut butter cups in flour helps them stay suspended in the batter rather than sinking to the bottom of the pan.
Be careful to not over-swirl the peanut butter so that you’ll get the thick, yummy swirls we’re showing.
Even though the thought of warm, gooey brownies fresh from the oven sounds amazing, warm brownies are impossible to cut into squares. Speed up the cooling process by putting them in the freezer for half an hour. Once they are cool, use a sharp knife and sawing motion to cut them, wiping the knife clean after each cut. A few seconds in the microwave will bring the brownies back to warm, fudgy perfection.
