Make the BEST one-bowl vegan sheet cake! It’s tender, fluffy, vanilla-scented, and easy to customize with add-ins/toppings to suit any birthday, party, or gathering!
Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius). Lightly grease and line a 9x13-inch sheet pan (or similar baking dish) with parchment paper.
In the bowl of a stand mixer, or a large bowl using a handheld electric mixer, combine all of the ingredients. Mix until the batter is smooth and lump-free.
Pour the batter evenly into the prepared sheet pan, spreading it into the corners with a spatula.
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Remove from the oven and allow the cake to cool in the pan for at least 15 minutes before slicing.
Serve plain or top with your favorite vegan frosting, powdered sugar, or fresh fruit.
Notes
Measure flour accurately: To avoid overly dense/dry cake, fluff the flour in its bag with a fork, spoon it into the measuring cup, then level with a knife.
Don’t over-mix the batter: Otherwise, the cake becomes dense and rubbery. A few very tiny lumps are fine.
Cool before slicing: It’s fragile right out of the oven. Even just 15 minutes will help prevent it from falling apart when slicing.
