  • Total Time: 25 minutes
  • Yield: 16 small squares

Ingredients

Brownie Base

  • 1/2 cup butter, or oil
  • 1 cup sugar
  • 1/2 cup unsweetened cocoa powder, preferably Dutch-processed
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/4 cup all-purpose flour
  • 1/4 teaspoon salt (leave out if using salted butter)

Add-Ins (Optional)

  • 1/2 cup favorite add-ins (chopped dark chocolate, chocolate chips, or walnuts)

Instructions

  1. Prepare Pan: Preheat your oven to 350°F (175°C). Grease an 8×8 inch square pan or a 9×5 inch loaf pan, or line it with parchment paper or foil to prevent sticking. Set aside.
  2. Melt Butter: In a large microwave-safe mixing bowl, add the butter and microwave for about 1 minute until completely melted. This creates the base fat for your brownie batter.
  3. Mix Sugar and Cocoa: Add the sugar and cocoa powder to the melted butter. Whisk vigorously for at least one minute to help dissolve the sugar and combine ingredients into a smooth mixture.
  4. Add Eggs and Vanilla: Crack in the eggs one at a time, whisking well after each addition. Then add the vanilla extract and continue whisking for at least one minute until the batter is shiny and well combined.
  5. Incorporate Flour and Salt: Stir in the flour and salt gently until just combined. Be careful not to overmix, as this can make the brownies tough.
  6. Add Optional Mix-Ins: If desired, fold in 1/2 cup of your choice of nuts, raisins, chocolate chips, or other favorite add-ins to add texture and extra flavor.
  7. Bake: Spread the batter evenly in the prepared pan. Bake for approximately 20 minutes, or until the center is just set but still slightly gooey. Avoid overbaking to maintain the fudgy texture.
  8. Cool and Serve: Allow the brownies to cool completely in the pan before cutting. Cut into 9 large or 16 small squares and enjoy!

Notes

  • Use Dutch-processed cocoa for a richer chocolate flavor, but natural cocoa powder works fine too.
  • If using salted butter, omit the added salt to avoid over-seasoning.
  • To keep brownies extra fudgy, do not overbake; watch for a slightly under-set center.
  • Replace butter with oil for a slightly different texture and a dairy-free option.
  • Mix-ins are optional but add great texture and variety.
