With straightforward ingredients and simple steps, you’ll have delicious homemade brownies in just about an hour.

Ingredients

1 cup (226 grams) unsalted butter
2 cups (400 grams) granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup (125 grams) all-purpose flour
¾ cup (75 grams) unsweetened cocoa powder
½ teaspoon baking powder

<½ teaspoon salt1 cup (175 grams) semi-sweet chocolate chips or chopped nuts

Instructions

Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking pan with butter or line it with parchment paper for easy removal.
Melt the butter in a large saucepan over medium heat or in a microwave-safe bowl in short bursts, stirring until smooth. Allow it to cool slightly.

In a large mixing bowl, combine the sugar and eggs, whisking until well blended and slightly frothy. Add the vanilla extract.
Slowly pour the melted butter into the egg mixture, whisking continuously to incorporate fully.
In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add these dry ingredients to the wet mixture, stirring gently until just combined. Do not overmix, as this can make the brownies tough.

Fold in chocolate chips or nuts if using, distributing evenly throughout the batter.
Pour the batter into the prepared pan, spreading it evenly with a spatula.
Bake in the preheated oven for 25-30 minutes. To check for doneness, insert a toothpick into the center; it should come out with moist crumbs but not wet batter.

Remove from the oven and allow the brownies to cool in the pan for about 15 minutes. Then, transfer to a wire rack or cut directly in the pan once cooled for easier serving.

Tips

Use high-quality cocoa powder for a richer flavor. Dutch-processed cocoa can give a smoother, less acidic taste, but natural cocoa works well too.
To make the brownies extra fudgy, slightly underbake them by a few minutes and let them cool completely before slicing.

If you prefer chewier brownies, replace some of the flour with an equal amount of cornstarch or use slightly less baking powder.
Store brownies in an airtight container at room temperature for up to 3 days or freeze for longer storage.

Serving Suggestions

Serve these brownies plain or dusted with powdered sugar. They pair wonderfully with a scoop of vanilla ice cream, a drizzle of caramel or chocolate sauce, or a dollop of whipped cream for an indulgent dessert. For a more festive touch, top with fresh berries or a sprinkle of sea salt.

Variations

For different flavor twists, consider adding:

Swirls of peanut butter or Nutella before baking
Chopped nuts like walnuts, pecans, or almonds for added crunch
White chocolate chips or dried fruit for a sweet contrast
A dash of espresso powder to intensify the chocolate flavor

Storage and Reheating

Brownies can be stored at room temperature in an airtight container for up to 3 days. To keep them fresh, place a paper towel underneath the lid to absorb excess moisture. For longer storage, wrap individual portions tightly with plastic wrap and freeze for up to 3 months. To reheat, microwave a brownie for about 15-20 seconds until warm, or reheat in a 350°F (175°C) oven for 5-7 minutes for a fresh-baked feel.

Frequently Asked Questions

Can I use margarine instead of butter?

Yes, margarine can be substituted for butter, but it may slightly alter the flavor and texture. For best results, use unsalted butter or a high-quality margarine designed for baking.

How do I know when the brownies are done?

Insert a toothpick into the center of the brownies. If it comes out with moist crumbs but no wet batter, they are ready. Keep in mind that slightly underbaked brownies will be fudgier, so adjust baking time based on your preference.

Can I make these brownies gluten-free?

Yes, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Ensure that other ingredients, like baking powder, are gluten-free as well.

What if I want to make them more cake-like?

To achieve a lighter, more cake-like texture, add an extra ½ teaspoon of baking powder and reduce the fat slightly. Baking for a few additional minutes may also help, but be careful not to overbake.

Can I double this recipe?

Absolutely. Doubling the ingredients and baking in a larger or two 9×13 pans will work well. Adjust baking time slightly, checking for doneness as usual.

Is it okay to freeze the batter?

It’s best to bake the brownies first and then freeze for storage. Freezing the raw batter is not recommended, as it can affect the texture and leavening when baked later.
