Why make this recipe
Because brownies are a ritual: compact, forgiving, and wholly indulgent. They demand little pomp but reward patience with a dense crumb that yields to a satin frosting. Make them when you want to fill a room with the smell of butter and dark cocoa, or when you’re looking to steady a restless evening with something reliably kind.
How to make Brownies with Frosting
These brownies begin as a simple, almost rustic batter that resolves into something lusciously dense. The texture is the point: the crumb should be tender yet substantial, with the frosting offering a cool, creamy counterpoint.

Ingredients:
- 1 cup melted butter
- 1/2 cup unsweetened cocoa powder
- 2 cups all purpose flour
- 2 cups sugar
- 1/2 teaspoon salt
- 4 eggs
- 3 tablespoons vanilla extract
For the Frosting:
- 1/4 cup melted butter
- 1/4 cup milk
- 3 cups powdered sugar
- 1/4 cup unsweetened cocoa powder
- 1 tablespoon vanilla extract
Directions:
Preheat oven to 350 degrees F. In a medium bowl, mix together the melted butter and cocoa powder until smooth. Add the flour, salt, and sugar then mix together. The mixture will be dry and crumbly. Add in the eggs and vanilla extract and mix until smooth. Line a 9×13 pan with parchment paper and pour batter into pan. Bake for 20 to 25 minutes, or until a toothpick inserted in the middle comes out clean. While the brownies are baking, make the frosting by whisking together the butter, milk, powdered sugar, cocoa powder, and vanilla extract until thick and spreadable. Let sit for 15 to 20 minutes before frosting. Then spread frosting over the top of the brownies. Let cool completely before slicing.
How to serve Brownies with Frosting
Slice with a long, sharp knife warmed under hot water and wiped dry to create clean edges. Serve slightly chilled or at room temperature so the frosting keeps a soft, slicing texture. Accompany with a small spoonful of crème fraîche, a scatter of flaky sea salt, or a steaming cup of espresso to contrast the frosting’s sweetness.
How to store Brownies with Frosting
Keep them covered at room temperature for up to two days in a cake tin or an airtight container, placing parchment between layers if you stack. For longer storage, wrap tightly and refrigerate for up to a week; bring to room temperature before serving to restore tenderness. You can also freeze uncut brownies for up to three months—wrap in plastic, then foil—and thaw overnight in the refrigerator.
Tips to make Brownies with Frosting
- Measure flour by spooning it into the cup and leveling; avoid packing to keep the crumb tender.
- Let the frosting sit until it loses any raw shine; this helps it set into a satiny layer rather than running.
- Use high-quality unsweetened cocoa for a more rounded chocolate flavor and a darker, more sophisticated color. For ideas about balancing frosting sweetness and texture, this caramel-spice method can be inspiring here.
- If you prefer fudgier brownies, shorten the bake time by a couple of minutes and err on the side of moist; they will continue to set as they cool.
Variations (if any)
- Brownie Sundae: Top warm slices with vanilla ice cream and a drizzle of hot fudge.
- Nutty Fold: Fold 1 cup of toasted walnuts or pecans into the batter for crunch and aromatics.
- Espresso Boost: Dissolve 1 teaspoon instant espresso powder in the melted butter for an intensified cocoa profile.
- Salted Caramel Swirl: Dollop caramel over the batter before baking and swirl gently for pockets of sweet-salty richness.
FAQs
Q: Can I use oil instead of melted butter?
A: Yes—use a neutral oil like canola or vegetable. Butter adds flavor and a certain gloss, so flavor will be slightly different but still delicious.
Q: Why did my frosting become grainy?
A: Graininess often comes from insufficiently whisked powdered sugar or cold butter. Ensure the frosting ingredients are at room temperature and whisk until smooth.
Q: How can I tell when brownies are done without overbaking?
A: Look for slightly set edges and a glossy, cracked top. A toothpick should come out with a few moist crumbs—not wet batter—to preserve a tender, dense center.
Q: Can I make these gluten-free?
A: Substitute a 1:1 gluten-free flour blend, but check for added xanthan gum in the blend and adjust—baked texture will be slightly different but still satisfying.
