Ingredients You’ll Need for Vegan Texas Sheet Cake

This recipe relies on everyday ingredients you may already have on hand.

For the Cake

• 2 cups all-purpose flour
• 1¾ cups organic cane sugar
• ½ cup unsweetened cocoa powder
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1 cup unsweetened plant milk (almond, soy, or oat)
• 1 cup warm water
• ½ cup neutral oil (such as sunflower or canola)
• 1 tablespoon apple cider vinegar
• 2 teaspoons vanilla extract

How to Make Vegan Texas Sheet Cake

This cake comes together fast, making it ideal for last-minute desserts or low-stress baking.

1. Preheat and prepare your pan:
   Preheat the oven to 350°F (175°C). Grease a large rimmed baking sheet (about 10 by 15 inches) or line it with parchment paper.
   
2. Mix the dry ingredients:
   In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
   
3. Add wet ingredients:
   Pour in the plant milk, warm water, oil, vinegar, and vanilla extract. Mix until smooth and well combined, but don’t overmix.
   
4. Bake the cake:
   Pour the batter into the prepared sheet pan and smooth the top. Bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean.
   
5. Make the icing:
   While the cake bakes, prepare the icing. In a small saucepan, melt the vegan butter over medium heat. Stir in the cocoa powder and plant milk, and bring just to a simmer. Remove from the heat and whisk in the powdered sugar, vanilla, and salt until smooth.
   
6. Frost while warm:
   As soon as the cake comes out of the oven, pour the warm icing over the top and spread evenly. If using chopped nuts, sprinkle them over the icing before it sets.
   
7. Cool and serve:
   Let the cake cool in the pan until the icing is set. Slice into squares and serve straight from the pan.

Serving Ideas for Vegan Texas Sheet Cake

This cake is delicious on its own, but you can easily dress it up if you’d like. Here are a few ideas:

Tips for the Best Texture and Flavor

For the richest and softest cake, keep these tips in mind:

• Don’t overmix the batter once the wet and dry ingredients are combined
• Use warm, not boiling, water to help bloom the cocoa powder
• Frost the cake while both the cake and icing are still warm
• Let the cake sit until the icing sets before slicing
