Ingredients

Scale

Brownie Batter

  • 1 batch of your favorite brownie batter (approximately 1 cup flour, 1 cup sugar, 1/2 cup cocoa powder, 2 eggs, 1/2 cup butter or oil, 1 tsp vanilla extract, 1/4 tsp salt)

Add-ins

  • 1/2 cup creamy peanut butter
  • 1/2 cup chocolate chips
  • 1/2 cup M&Ms

Instructions

  1. Prepare Brownie Batter: In a mixing bowl, combine all your brownie batter ingredients until smooth and thoroughly mixed to create the base for these fudgy brownies.
  2. Add Mix-ins: Gently fold in the peanut butter, chocolate chips, and M&Ms into the brownie batter, ensuring they are evenly distributed for a flavorful bite in every piece.
  3. Bake: Pour the batter into a greased or lined baking pan. Bake in a preheated oven at 350°F (175°C) for about 25-30 minutes or until the brownies are set but still fudgy in the center. Insert a toothpick that comes out with a few moist crumbs to indicate perfect doneness.
  4. Cool and Serve: Allow the brownies to cool in the pan before cutting into squares. Serve as a delightful dessert or snack that combines the best of cookies and brownies.

Notes

  • Peanut butter can be swirled into the batter instead of mixed fully for a marbled effect.
  • Use mini M&Ms for better distribution throughout the batter.
  • Adjust baking time slightly if using a glass pan or different oven type.
  • Store brownies in an airtight container at room temperature for up to 3 days or in the fridge for up to a week.
  • For a nut-free version, omit peanut butter and replace with sunflower seed butter.
