Homemade fudgy brownies are inexpensive and simple to make in one bowl—just like a boxed mix. Super moist and intensely chocolatey, these brownies disappear fast.

Although I’ve been blogging for years, I realized I hadn’t posted a simple classic brownie recipe—so here it is: fudgy brownies with no frills and no extras, just rich chocolate flavor and a tender, gooey interior.

Fudgy Brownies
This recipe is designed to be made in ONE BOWL, much like a boxed mix. The base uses dry cocoa powder instead of melted chocolate, so it stays affordable and easy. You only need a few pantry staples—eggs, butter (or oil), water, and vanilla—to transform the dry mix into a dense, fudgy batter.

The finished brownies have a slightly crisp, cracked top and a moist, dense center—definitely not cake-like. They’re best when cooled slightly or chilled for neat slices, though warm with ice cream is a lovely treat.

I do use boxed mixes sometimes because they’re easy to dress up, but this homemade version stands on its own. No frosting or add-ins are required—though chocolate chips or a scoop of vanilla ice cream are nice options if you like.

These brownies are forgiving and quick to prepare. They’re kid-approved—mine disappeared fast—so they’re perfect for family snacks, potlucks, or whenever you need a reliable chocolate fix.
Below is a clear ingredient list and straightforward instructions so you can make a 13×9-inch pan of fudgy brownies with minimal fuss.
Fudgy Brownies
Ingredients
- 2 cups (400 g) granulated sugar
- 1 cup (120 g) all-purpose flour
- 2/3 cup (54 g) cocoa powder (feel free to use a mix of regular and dark cocoa)
- 1/2 tsp baking powder
- 1/2 tsp salt
- 2 large eggs
- 1/2 cup (113 g) butter, melted (1 stick) — or substitute oil
- 1/4 cup (59 ml) water
- 1 1/2 tsp vanilla extract
Instructions
- Preheat the oven to 350°F (175°C). Grease a 13×9-inch baking dish, or line it with parchment for easy removal.
- In a large bowl, whisk together the sugar, flour, cocoa powder, baking powder, and salt. (This dry mix can be stored in an airtight container for up to 12 months.)
- Add the eggs, melted butter (or oil), water, and vanilla. Stir until the flour barely disappears; the batter will be thick. Spread the batter evenly in the prepared pan.
- Bake at 350°F: 35–45 minutes for a glass pan or 25–35 minutes for a metal pan. Bake until a toothpick inserted in the center comes out clean. Let cool slightly or completely before cutting for the cleanest slices.
Notes
* You may use oil instead of butter. Brownies made with oil can have slightly crisper edges and may take a bit longer to bake.
* To make an 8×8-inch or 9×9-inch pan, halve the recipe.
* Recipe adapted from a classic boxed-style approach.
