The slices are thin, like a sheet cake should be. If you would like to bake this in a 9×13 you’ll need to decrease the oven temperature to 350° and increase the bake time to about 20 minutes!

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

Cake just wasnt good. I used good ingredients. Made it twice because thought i over mixed first one but nope second time around turned out same. Even waited a day. Its more dense than pound cake and way not buttery. I made cake cause of how many stars it was only afterwards i read these reviews. Most have not actually made cake.

Do you think it would be possible to decorate this with fruit on top after icing? Or would the consistency of the icing prevent this?

I have made the chocolate Texas sheet cake many times, but the event I am making it for required a white or yellow cake. Since I am familiar with this type of recipe I knew it would be thin. I upped the whole recipe by 1/2 and baked it in a deeper pan that was the same size 11×17. And I used some vegetable oil with the melted butter with out any problems. It did require longer baking to finish it. But its a perfect easy recipe. Love seeing the boy making the recipe in the photos. That is how… Read more »

I just read the frosting comments. Since I was trying to use up buttermilk, I made a glaze from an online recipe & it turned out great. It is super easy too make and easy to frost your cake: 2 cups confectioner’s sugar, 1 teaspoon vanilla extract & 1/4 cup buttermilk. Combine the ingredients & whisk until smooth. Pour glaze over slightly warm cake. Cool completely & allow glaze to set. I always add sprinkles.

I enjoyed this cake but it wasn’t what I thought it would be. I was VERY excited to make it; easy, beautiful, sounded delicious! I made it for my daughter’s 1st birthday. I make many cakes and have a baking background so I know good stuff. The only change I made was to the frosting; I added about 1/4 c. strawberry jam and a bit less powdered sugar. It was amazing. The cake cut wonderfully. Beautiful little squares that held up nicely. A bit dense, moist and creamy, the cake shouldn’t be eaten with a fork. It’s so thin (expected)… Read more »

I made this today in a 9×13 pan, baked at 350 for 43 min, and it was so perfect. No icing needed. Practically melted in my mouth with this amazing thin crust on top. So good, everyone loved! And best of all, batter came together in under 30 min! Thank you so much for this recipe! My new go-to vanilla cake! Merry Christmas!

Made this whilst making dinner it’s that easy!!! Only made half the frosting which was plenty. So very yummy ? Will definitely make again!

This cake is so easy and delicious. It’s definitely very sweet but super moist with a wonderful flavor. We cut it into small squares and don’t feel the need to eat a huge piece at a time. It’s almost like eating a piece of vanilla/buttermilk fudge (not the same consistency but in the same way that a small piece of fudge is satisfying). Everyone seems to rave about this cake. Yum!!
