Ingredients
- 1 cup (225g) unsalted butter, melted
- 1 ¼ cups (250g) granulated sugar
- ¾ cup (150g) packed light brown sugar
- 4 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- 1 cup (85g) unsweetened cocoa powder, sifted
- 1 cup (130g) all-purpose flour, sifted
- ½ teaspoon baking powder
- ½ teaspoon salt
- ½ cup (90g) semi-sweet chocolate chips or chunks (optional)
Instructions
- Preheat your oven to 350°F (175°C). Grease and line an 8-inch (20 cm) square cake pan with parchment paper, leaving an overhang on two sides for easy removal.
- In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth and well combined.
- Add the eggs one at a time, whisking thoroughly after each addition to ensure the mixture is glossy and slightly thickened.
- Stir in the vanilla extract.
- In a separate bowl, sift together the cocoa powder, flour, baking powder, and salt.
- Gradually fold the dry ingredients into the wet mixture using a spatula or wooden spoon. Mix gently until just combined — avoid overmixing to keep the cake tender.
- If using, fold in the chocolate chips or chunks for an extra melty chocolate texture.
- Pour the batter evenly into the prepared pan, smoothing the top with a spatula.
- Bake in the preheated oven for 30-35 minutes. Check doneness by inserting a toothpick into the center — it should come out with a few moist crumbs but not wet batter.
- Allow the brownie cake to cool completely in the pan on a wire rack before lifting it out using the parchment paper edges.
- Slice into squares or wedges and serve as desired.
Tips
- Substitutions: You can swap the all-purpose flour for whole wheat pastry flour for a nuttier flavor, but the texture may be slightly denser. For a gluten-free version, use a 1:1 gluten-free baking flour blend.
- Butter alternatives: Unsalted butter is best for flavor control, but you can use coconut oil or a neutral vegetable oil if necessary. Note that oil will make the cake a bit more moist and tender.
- Don’t overbake: Overbaking dries out brownie cake. Check it 5 minutes before the minimum time and watch closely. The center should still be fudgy.
- Cooling is crucial: Letting the cake cool fully before slicing ensures clean cuts and helps the texture set properly.
Serving Suggestions
This brownie cake is versatile and pairs wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream for contrast. For a more decadent experience, drizzle warm caramel or chocolate sauce on top. Fresh berries like raspberries or strawberries add a bright, tart note that balances the richness. You can also dust the top lightly with powdered sugar for a simple presentation.
Variations
Customize this brownie cake to your taste by adding chopped nuts such as walnuts or pecans for crunch. For a mocha twist, add 1 tablespoon of instant espresso powder to the dry ingredients. Swirl in peanut butter or cream cheese before baking for pockets of creamy flavor. To make it vegan, substitute eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) and use dairy-free butter alternatives.
Storage and Reheating
Store the brownie cake covered tightly at room temperature for up to 3 days to keep it moist. For longer storage, wrap it well in plastic wrap and aluminum foil, then refrigerate for up to 1 week or freeze for up to 3 months. When freezing, slice the cake first and separate pieces with parchment paper for easy thawing.
To reheat, warm individual slices in the microwave for 10-15 seconds or in a preheated 300°F (150°C) oven for 5-7 minutes. Avoid overheating to maintain fudginess.
Frequently Asked Questions
- Can I use Dutch-processed cocoa powder instead of natural cocoa?
- Yes, but Dutch-processed cocoa is less acidic and has a milder flavor. Since this recipe does not use baking soda (which reacts with acidity), the texture won’t be affected, but the taste will be slightly smoother and less sharp.
- Why is my brownie cake dry or crumbly?
- Dryness usually results from overbaking or too much flour. Make sure to measure flour accurately by spooning it into the cup and leveling it off. Also, check your oven temperature with an oven thermometer, as ovens can run hot and cause overbaking.
- Can I make this recipe in a round cake pan?
- Absolutely. Use a 9-inch round pan and adjust baking time to 25-30 minutes, checking for doneness with a toothpick. The edges may bake faster, so keep an eye to prevent burning.
- How do I get a fudgier brownie cake?
- To increase fudginess, slightly reduce the flour to ¾ cup (about 100g) and avoid overmixing. You can also add an extra egg yolk for richness. Be careful not to underbake, though—fudgy doesn’t mean raw.
- Can I add frosting or ganache on top?
- Yes, this cake pairs beautifully with a chocolate ganache or cream cheese frosting. Allow the cake to cool completely before frosting to prevent melting. For ganache, heat equal parts heavy cream and chopped chocolate until smooth, then pour over the cake.
- Is it better to use melted or softened butter?
- Melted butter helps create a denser, fudgier texture by coating the flour and reducing gluten formation. Softened butter would aerate the batter more, resulting in a cakier texture, which is less typical for brownie cake.
With this recipe, you can confidently create a luscious homemade chocolate brownie cake that satisfies any chocolate craving. Its rich, fudgy crumb and ease of preparation make it a staple dessert for any occasion.
