I could honestly devour an entire version of this classic Southern cake solo (I do admit to having zero self-control). So I figured, let’s make Texas sheet cake cookies!

Does anyone else have a parent with a nondescript box of recipes, many of which include lightly tanning magazine clippings from decades prior? Yeps. And I aspire to be one of those people in the years to come.

From that magical tin box, this recipe was (kind of) formed via a restructuring of an old cake recipe from a Southern Living clipping.

TEXAS SHEET CAKE COOKIES

For those who don’t know, Texas sheet cake is a chocolate cake, literally baked on a sheet pan, and covered in a thick chocolate frosting. The combo of the thin cake with the fudgy frosting (which is literally the best icing) makes the whole situation oh so good.

I was shocked to see that there aren’t many recipes for a Texas sheet cake cookie made from scratch. Of the few I could find, most included a box cake mix. Color me stunned.

They also looked dry and unappetizing, so basically, this recipe creation was a need for a cookie that embodied the true fluffy, fudginess of a proper Texas sheet cake, just in cookie form.

Don’t go “over” with these cookies! Mix just until the ingredients come together, then bake until just done (as instructed below). You want a soft and fudgy cookie, not dry and dense.

INGREDIENTS

Butter: Adds rich flavor and moisture to both the cookies and frosting.
Sugar: Sweetens the cookies and helps them bake up soft and tender.
Sour cream: Keeps the cookies moist and gives a subtle tang that enhances chocolate flavor.
Egg: Binds the ingredients together and adds structure.
Flour: Provides the base and texture for the cookies.
Baking soda: Helps the cookies rise slightly and stay soft.
Salt: Balances sweetness and enhances flavor.
Cocoa powder: Gives the cookies and frosting their deep chocolate taste.
Milk: Creates a smooth, spreadable consistency in the frosting.
Powdered sugar: Sweetens and thickens the frosting to a creamy, fudgy texture.
Vanilla extract: Enhances and rounds out the chocolate flavor.

Frost your cookies while your icing is warm! The chocolate frosting will get thicker as it sets, so it’s easier to spoon on while warm and will set fudgy on top of your soft cookies.

HOW TO MAKE TEXAS SHEET CAKE COOKIES

Start by creaming together the butter and sugar in a large mixing bowl until light and fluffy. Mix in the sour cream, then add the egg and blend until smooth.

In a separate bowl, sift together the flour, cocoa powder, salt, and baking soda to evenly distribute the dry ingredients. Gradually add this mixture to the wet ingredients, mixing just until combined to keep the cookies soft and tender.

Preheat your oven to 350°F and line a baking sheet with parchment paper. Scoop about two tablespoons of dough per cookie, roll into balls, and place them evenly spaced on the prepared tray.

Bake for about 8 minutes, until the cookies are puffed and dry-looking on top but still soft inside—avoid overbaking to maintain their fudgy texture. Let them rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Once the cookies are cooled, prepare the chocolate frosting by melting butter in a saucepan over medium heat. Whisk in the milk and cocoa powder, bringing the mixture to a gentle boil before removing it from the heat.

Add the powdered sugar gradually, whisking until smooth and creamy, then stir in the vanilla extract for flavor. The frosting should be thick and glossy, perfect for spreading over the cookies.

Generously spoon the warm frosting onto each cooled cookie, letting it settle naturally over the tops for that signature Texas sheet cake look. Allow the cookies to rest for at least 30 minutes or until the frosting sets.

TIPS & VARIATIONS

Don’t overmix your cookie dough! You want these to be soft and fudgy chocolate cookies, not dense and dry.
If you prefer a thinner frosting, halve the below frosting recipe. Then whisk in a tablespoon of milk at a time until it reaches your desired consistency.
Make sure to spoon your frosting on while it’s warm, so it sets on top of the cookies (not in the pot).
When spooning your frosting on, place your baking tray or parchment paper under the cookies. It will run a little and this makes for easier clean up!

Notes

*This frosting is on the thicker side so if you want to thin it out ahead of time, add a tablespoon of milk at a time until it reaches your desired consistency.

*As mentioned above, this recipe is adapted from a Texas sheet cake recipe in an old Southern Living magazine clipping. The fudgy frosting above is the same as that clipping. Shoutout to Beverly McCravy from Smyrna, Georgia as it looks like your name is associated with the original recipe. Bless you!
