How to Make Classic Texas Sheet Cake

Step 1: Preheat and Prepare the Baking Pan
- Preheat your oven to 350°F (175°C).
- Grease and flour a 10×15-inch baking pan to prevent sticking.
Step 2: Make the Cake Batter
- In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt.
- Add the sour cream and eggs, mixing until smooth.
Step 3: Prepare the Cocoa Mixture
- In a medium saucepan, melt 1 cup butter over low heat.
- Stir in water and 5 tablespoons cocoa powder, then bring the mixture to a gentle boil.
- Remove from heat and let it cool slightly before adding it to the flour mixture.
Step 4: Combine and Bake
- Pour the warm cocoa mixture into the flour mixture and stir until smooth and fully combined.
- Spread the batter evenly into the prepared baking pan.
- Bake for 20 minutes, or until a toothpick inserted in the center comes out clean.
Step 5: Prepare the Chocolate Icing
- While the cake is baking, combine the milk, cocoa powder, and butter in a large saucepan over medium heat.
- Bring to a gentle boil, then remove from heat.
- Stir in the confectioners’ sugar and vanilla extract until smooth.
- Fold in the chopped walnuts, if using.
Step 6: Ice the Cake While It’s Warm
- Immediately pour the warm icing over the warm cake—this helps it soak in slightly for that signature fudgy texture!
- Spread evenly, ensuring every inch is covered in chocolate goodness.
- Let it set for a few minutes before slicing and serving.
What to Serve with Texas Sheet Cake

Tips for the Best Texas Sheet Cake
✔ Use sour cream for extra moisture – It makes the cake incredibly soft.
✔ Pour the icing while the cake is warm – This helps it melt into the cake slightly for that signature texture.
✔ Don’t overbake – Check the cake at 18 minutes to ensure it stays moist and tender.
✔ Add a pinch of cinnamon – For a true Texas twist, mix a pinch of cinnamon into the cake batter.
✔ Let the cake cool slightly before cutting – This helps the icing set and makes for cleaner slices.
