How to Make Texas Sheet Cake Brownies

Once you try these Texas sheet cake brownies, you’ll be hooked on their incredible texture and flavor.

1. PREP: Preheat the oven to 350°F. Grease a 13×18-inch sheet pan and line it with parchment paper.

4. BAKE: Pour the batter into the prepared pan and spread evenly. Bake for 20-25 minutes.

Tips For the Best Texas Sheet Cake Brownies

The secret to these brownies is in the method. Melting the butter with chocolate guarantees the best taste and texture.

Meanwhile, beating the eggs with the sugars is how you get that yummy crackly top we all love so much.

And don’t even get me started on the frosting! It’s like a velvety chocolate dream that pairs perfectly with the brownie base.

Need a few more tips? I’ve got you covered:

• Use parchment. Line the sheet pan with parchment paper for easy removal and cleanup.

• Melt the butter properly. Keep the heat on medium-low and take the pan off the heat as soon as the butter is melted. Stir constantly until the chocolate melts (a few lumps are okay).

• Mix gradually. Stir the butter/chocolate and the dry ingredients in by hand. Mix just until combined.

• Avoid overbaking. Bake until a toothpick comes out with a few moist crumbs; do not overbake to maintain fudginess. The brownies will keep cooking a little in the hot pan, so pull them early to be safe.

• Frosting tips. Prepare the frosting while the brownies bake. It should be warm and go on the warm cake for the best texture.

• Chill before slicing. It’s tough, but chill brownies before slicing for cleaner cuts and enhanced flavor.

• Variations. For a unique twist, experiment with different toppings, such as Reese’s Peanut Butter Cups, Snickers, or M&Ms.
