Ingredients

  • 1 ¼ cup All-Purpose Flour
  • ½ teaspoon Baking Soda
  • ¼ teaspoon Salt
  • 3 Eggs
  • 1 cup Granulated Sugar
  • ½ teaspoon Vanilla Extract
  • 8 tablespoon Unsalted Butter 1 stick
  • 1 ½ cup Semi-Sweet Chocolate Chips divided
  • ¼ cup Creamy Peanut Butter

Instructions

  • Preheat oven to 350 degrees F. Grease an 8x8 pan.
  • In a medium bowl, combine flour, baking soda, and salt.
  • In a separate large mixing bowl, add eggs, granulated sugar, and vanilla. Mix until eggs are broken and well incorporated.
  • In a small saucepan, melt the butter over low heat. Add 1 cup of chocolate chips and stir until fully melted. Remove from heat and allow to cool 1-2 minutes, but not harden.
  • Add the melted chocolate to the egg mixture and cream together.
  • Add in the dry ingredient mixture and mix until smooth. With a spoon or flat spatula, stir in the remaining ½ cup of chocolate chips.
  • Pour the brownie batter into the greased pan. In a small bowl or cup, heat the peanut butter in the microwave for about 15 second and stir until smooth and slightly runny. Using a spoon, put small dollops of peanut butter over the surface of the brownie batter. Using a knife, marble the surface of the batter in a random pattern. When satisfied, gently shake the pan if the surface needs to be leveled.
  • Bake for about 23-30 minutes or a toothpick inserted in the center comes out only with a few moist crumbs. Metal pans take longer than glass. Do not over-bake- brownies will continue to cook a tiny bit during the cooling process.

Notes

How Do I make Brownies More Fudgy?
As written, these brownies are rich but not gooey or extremely fudgy. They still have a good structure that melts in your mouth. If you would like more of a fudgy texture, use real chocolate, not chips or baking chocolate. (It has more natual oils). You can also increase the butter by 4 Tbsp.
How to store brownies?
Store brownies at room temperature either well-wrapped in plastic or an airtight container such as a freezer bag. They are best enjoyed within 1-2 days.
