What makes white Texas Sheet Cake different?
It is very similar to the traditional recipe but with white cake and white icing instead of chocolate. I usually compare it to blondies versus brownies.

How to make white Texas sheet cake
- Step 1. First, preheat the oven to 350 degrees. While the oven is preheating, prepare the baking pan. You will need a 10×15 baking sheet or jelly roll pan. Go ahead and grease and flour the pan.

Step 1. Second, mix the flour, sugar, baking soda and salt. Once the flour mixture is combined, beat in the sour cream and eggs and set this aside.

Step 2. Next, melt the butter on low in a saucepan and add the water. Once melted, bring this mixture to a boil and remove from heat. Let the butter cool slightly and stir the butter mixture into the egg mixture. Mix this until well combined.

Step 3. Now, get the baking pan you prepared earlier. Pour the batter into it and bake for 20 minutes. Make the frosting while it bakes.

Step 4. Get out a large saucepan and add the milk and butter. Let this come to a boil and remove from the heat. Add the powdered sugar and vanilla and combine. Gently fold in the nuts. Spread on the cake and enjoy.

How to store the cake?
Cover the sheet pan with foil until ready to eat. The cake should keep up to 5 days.
If you refrigerate the cake, let it sit at room temperature before serving. This is important as it tastes much better at room temperature.
Tips and tricks
- You can substitute almond extract for the vanilla extract. The almond flavor goes well with this white version of Texas sheet cake.
- 9×13 pan- Traditionally this recipe uses a jelly roll or rimmed baking sheet. However, if you want a thicker type cake, use a 9×13 pan. Make sure to adjust the cooking time to about 30 to 35 minutes.
- Nuts- Walnuts are optional but so delicious. Just use what you prefer. If you do not like nuts, leave them off. You can even do half and half if your family is divided on preference.
- The cake is even better the longer it sits. Due to this, I like to make it at least a day in advance before I plan to serve it.
