These Chocolate Chip One Bowl Brownies are rich, fudgy, and irresistibly chocolatey, made using a simple one-bowl method that makes cleanup a breeze. Featuring three layers of semi-sweet chocolate chips—melted in butter, mixed in the batter, and sprinkled on top—these brownies bake into a perfectly moist, decadent dessert ideal for chocolate lovers.

  • Total Time: 35 minutes
  • Yield: 9 servings

Ingredients

Brownie Batter

  • 1/2 cup unsalted butter (salted butter may be used if you prefer a more salty-sweet dessert)
  • 1 1/2 cups semi-sweet chocolate chips (divided into 3 portions: 1/2 cup melted with butter, 1/2 cup mixed in batter, 1/2 cup sprinkled on top)
  • 1 cup granulated sugar
  • 1/2 cup unsweetened natural cocoa powder
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 3/4 cup all-purpose flour
  • 1/2 teaspoon salt (or to taste; flaky sea salt can be sprinkled on top before baking as an option)
  • 1/2 teaspoon baking powder (optional; omit for ultra fudgy, flat, dense brownies)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper or nonstick aluminum foil for easy cleanup. Spray the lined pan lightly with cooking spray and set aside.
  2. Melt Butter and Chocolate: In a large microwave-safe bowl, add the butter and microwave on high for about 1 minute until melted. Add 1/2 cup of semi-sweet chocolate chips to the melted butter and stir until smooth. If the chips do not melt completely, microwave in 10-second intervals, stirring each time, until fully melted.
  3. Combine Wet Ingredients: Let the melted chocolate mixture cool briefly so it won’t cook the eggs. Then add the granulated sugar, cocoa powder, eggs, and vanilla extract. Whisk the mixture together until fully combined and smooth.
  4. Add Dry Ingredients: Gradually add the all-purpose flour, salt, and baking powder to the wet ingredients. Stir gently until just combined; avoid overmixing to keep brownies tender.
  5. Fold in Chocolate Chips: Add the remaining 1/2 cup chocolate chips into the batter and stir to distribute evenly.
  6. Transfer to Pan and Top: Pour the thick batter into the prepared baking pan and spread it evenly with a spatula. Sprinkle the last 1/2 cup of chocolate chips evenly over the top. Lightly press them down so they stick to the batter.
  7. Bake: Bake the brownies in the preheated oven for about 25 minutes, or until the edges are set and a toothpick inserted in the center comes out clean or with a few moist crumbs (no wet batter).
  8. Cool and Serve: Allow the brownies to cool completely in the pan on a wire rack for 1 to 2 hours. Once cooled, slice into 9 pieces for rich, decadent squares, or cut into 12 or more pieces if you prefer smaller portions.

Notes

  • For fudgier, denser brownies, omit the baking powder.
  • Salted butter can be used for a contrast of salty-sweet flavor.
  • Sprinkling flaky sea salt on top before baking adds a lovely texture and taste dimension.
  • Letting brownies cool fully ensures cleaner slices and better texture.
  • The recipe yields 9 rich brownies, but you can cut them smaller for more servings.
