How to Make Fudgy Brownies: A Step-by-Step Chocolate Brownie Recipe

Few desserts inspire as much devotion as a perfectly baked brownie. Rich, dense, and intensely chocolatey, a good brownie walks the line between cake and candy, delivering a fudgy center with a crackly top that shatters at the first bite. Whether you are a seasoned baker or someone who is simply craving something sweet on a quiet afternoon, learning how to make brownies from scratch is a skill worth having. This recipe keeps things simple and dependable, using pantry staples to create a batch of dark, decadent squares that taste like they came from a specialty bakery. Serve them warm with a scoop of vanilla ice cream, pack them into lunchboxes, or bring them to a gathering where they will disappear within minutes. Let's walk through the process step by step.

The Ultimate Fudgy Brownie Base

This classic brownie recipe produces a deep, dark chocolate flavor with a moist, almost molten interior. The secret lies in melting the butter and chocolate together gently before folding in the dry ingredients by hand, which keeps the crumb tender instead of tough. A generous amount of cocoa powder boosts the chocolate intensity, while a touch of espresso powder (optional) deepens the flavor without making it taste like coffee. Let the brownies cool completely before slicing for the cleanest edges, though a warm, gooey square straight from the pan is a reward worth savoring. Below are the ingredients you will need for a standard 8-inch square pan.

1/2 cup (115 g) unsalted butter, plus extra for greasing
4 oz (115 g) dark chocolate, roughly chopped (60–70% cocoa recommended)
3/4 cup (150 g) granulated sugar
1/4 cup (50 g) packed brown sugar
2 large eggs, at room temperature
1 teaspoon vanilla extract
1/2 cup (65 g) all-purpose flour
1/3 cup (30 g) unsweetened cocoa powder
1/4 teaspoon fine salt
1/2 teaspoon espresso powder (optional)
1/2 cup (85 g) chocolate chips or chunks (optional)

Making the Batter and Baking to Perfection

Once your ingredients are assembled, the process moves quickly. The key is to avoid overmixing once the flour goes in, as gluten development is what turns a fudgy brownie into a dry, cakey one. For an even richer result, consider stuffing the batter with a layer of chocolate spread or a second type of chocolate before baking—an easy upgrade that adds a molten surprise in the center of each square. Follow the steps below for consistent results every time.

Preheat the oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving an overhang on two sides, and lightly grease the paper.
In a heatproof bowl set over a pot of barely simmering water, melt the butter and chopped dark chocolate together, stirring until smooth. Remove from the heat and let cool for 5 minutes.
Whisk both sugars into the warm chocolate mixture until well combined, then beat in the eggs one at a time, followed by the vanilla extract, until the batter looks glossy and thick.
In a separate bowl, sift together the flour, cocoa powder, salt, and espresso powder if using. Add the dry ingredients to the wet mixture and fold gently with a spatula until just combined—stop as soon as no streaks of flour remain.
Fold in the chocolate chips or chunks, if using. If you want a stuffed center, pour half the batter into the pan, spread a layer of chocolate spread or whole chocolate pieces over it, then top with the remaining batter.
Spread the batter evenly in the prepared pan and bake for 22–28 minutes, until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs. Avoid overbaking for the fudgiest texture.
Cool the brownies completely in the pan on a wire rack, about 1 hour, before lifting them out using the parchment overhang and slicing into squares with a sharp knife.

Store leftover brownies in an airtight container at room temperature for up to 4 days, or freeze individual squares wrapped tightly for up to 3 months. Reheat briefly in the microwave for that freshly baked, gooey experience whenever the craving strikes.
