Frosted Texas Sheet Cake Brownies

Texas sheet cakes are something I rarely make because I never ‘need’ an enormous chocolate cake laying around.

Enter: an 8-inch pan of ultra fudgy brownies topped with Texas sheet cake frosting — which is a boiled cocoa powder frosting — and I’ve got the best of both worlds. I can fulfill my chocolate fix with a manageable pan size.

The brownies are an easy, one-bowl, no-mixer recipe that’s as fast as using a boxed mix and they turn out fudgy with zero cakiness. The frosting comes together in about 1 minute on the stove (sometimes called 1-minute frosting) and you can add nuts if you prefer them on your Texas sheet cake.

It’s a brownie base I’ve fallen in love with because it’s easy and always delivers amazing results. Rich, decadent, and addicting!

How to Make Texas Sheet Cake Brownies

Making Texas sheet cake brownies with chocolate frosting is very easy, but you need to let the brownies cool completely before slicing. The frosting is added to the brownies while they’re still warm, so both the brownies and the boiled frosting need time to cool and set up.

Here’s how the brownies are made:

  1. Brownies: Melt the butter and chocolate together in the microwave.
  2. Stir in the eggs, sugar, vanilla, optional coffee, optional espresso granules.
  3. Add the flour and salt.
  4. Turn the brownie batter into an 8×8-inch baking dish that’s been sprayed with non-stick spray.
  5. Bake until the center of the brownies has just set but is still slightly glossy.
  6. Frosting: While the brownies cool, make the frosting. Add the butter, milk, and cocoa powder to a saucepan and bring the mixture to a boil.
  7. Boil for 15 seconds, then remove from the heat and stir in the confectioners’ sugar and vanilla. Add the nuts, if using.
  8. Turn the routing over the still-warm brownies.
  9. Cool completely before serving.

Tip

The coffee and instant espresso granules do NOT make the Texas sheet cake brownies taste like coffee! They simply enhance the chocolate flavor and make the brownies even richer.

Add the frosting on top of the brownies while they’re still warm. The frosting and brownies will both set up as they cool.

I prefer to cover the brownies with foil and refrigerate for a few hours or overnight because they’re easier to slice when chilled and I prefer the taste when chilled.

Texas Sheet Cake Brownies

By Averie Sunshine
The brownies are an easy, one-bowl, no-mixer recipe that’s as fast as using a boxed mix and they turn out fudgy with zero cakiness. The frosting comes together in about 1 minute on the stove (sometimes called 1-minute frosting) and you can add nuts if you prefer them on your Texas sheet cake. I like to store the brownies in the fridge but they’re fine at room temp.

Ingredients  

Brownies

  • ½ cup unsalted butter, 1 stick
  • 6 ounces dark or bittersweet chocolate, chopped (I used Trader Joe’s 72% Pound Plus Bar)
  • 2 large eggs
  • ¾ cup granulated sugar
  • 1 tablespoon vanilla extract
  • 1 tablespoon brewed coffee, leftover or cold coffee is okay, optional but recommended
  • 1 teaspoon instant espresso granules, optional but recommended
  • ¾ cup all-purpose flour
  • ½ teaspoon salt, or to taste

Frosting

  • ¼ cup unsalted butter, half of 1 stick
  • 3 tablespoons milk, I used unsweetened cashewmilk
  • 3 tablespoons unsweetened cocoa powder
  • 1 ¾ to 2 cups confectioners’ sugar
  • 1 teaspoon vanilla extract
  • ¾ cup chopped walnuts or pecans, optional

Instructions 

Brownies

  • Preheat oven to 350F. Line an 8-inch square pan with aluminum foil leaving overhang and spray with cooking spray, or grease and flour the pan; set aside.
  • To a large microwave-safe bowl, add the butter, chocolate, and heat on high power to melt, about 2 minutes. Stop to check and stir after 1 minute. Heat in 15-second increments until chocolate has melted and mixture can be stirred smooth. Allow mixture to cool momentarily before adding the eggs so they don’t scramble.
  • Add the eggs, sugar, vanilla, optional coffee, optional espresso granules (neither make brownies taste like coffee and both enhance and round out the chocolate flavor), and whisk vigorously to combine.
  • Add the flour, salt, and stir until smooth and combined without overmixing.
  • Turn batter out into prepared pan, smoothing the top lightly with a spatula as necessary.
  • Bake for about 20 to 25 minutes, or until center has just set and is no longer glossy. A toothpick should come out clean or with a few moist crumbs, but no batter. Allow brownies to cool in pan on top of a wire rack while you make the frosting.

Chocolate Frosting

  • To a medium saucepan, add the butter, milk, cocoa powder, and heat over medium-high to melt butter. Whisk constantly until butter has melted. Allow mixture to come to a boil and boil for about 15 seconds before removing from the heat.
  • Add 1 3/4 cups confectioners’ sugar, vanilla, and whisk until smooth and combined. If you like a tighter frosting add the remaining 1/4 cup sugar.
  • Optionally add the nuts.
  • Evenly add frosting to the brownies, using a spatula to spread it as necessary.
  • Allow brownies to cool uncovered for at least 1 hour before slicing and serving. I prefer to cover the brownies with foil and refrigerate for a few hours or overnight because they’re easier to slice when chilled and I prefer the taste when chilled.

Notes

Storage: Brownies will keep airtight at room temp for up to 1 week, in the fridge for up to 2 weeks, or in the freezer for up to 6 months.

  1. Hi Averie! I came here via the link provided in the Texas Sheet Cake recipe, which I received in today’s email. As this is also a sheet pan recipe, albeit a smaller one, I was wondering if margarine could also be used successfully in this recipe? Thanks so much!

    1. I don’t know because I haven’t tried it. In general, it’s better to bake with butter not margarine. The Texas Sheet Cake I posted is an exception because it’s an old timey recipe and that was common back then. I haven’t tested the brownies with margarine but this brownie base is just so good. I would not change it! Just use butter.
