Ingredients

29 cups (250g) all-purpose flour
19 cups (400g) granulated sugar
38 tsp baking powder
8 tsp baking soda
4 tsp salt
1 cup (240ml) whole milk, room temperature
cup (80ml) vegetable oil or canola oil
2 large eggs, room temperature
2 tsp pure vanilla extract
1 cup (240ml) boiling water

Instructions

Preheat your oven to 3506F (1756C). Grease a 9×13-inch baking pan with butter or nonstick spray and lightly flour it, or line it with parchment paper for easier removal.
In a large mixing bowl, sift together the flour, sugar, baking powder, baking soda, and salt to ensure even distribution of leavening agents.

In a separate medium bowl, whisk the milk, oil, eggs, and vanilla extract until combined and smooth.
Gradually add the wet ingredients to the dry ingredients, stirring gently with a spatula or wooden spoon until just combined. Avoid overmixing to keep the cake tender.
Carefully pour in the boiling water and stir slowly until the batter is smooth and slightly thin. This step helps create a moist crumb by hydrating the flour fully.

Pour the batter evenly into the prepared 9×13 pan. Tap the pan gently on the counter to release any air bubbles.
Bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs attached.
Remove the cake from the oven and let it cool in the pan for 15 minutes. Then transfer it to a wire rack to cool completely before frosting or serving.

Tips

Substitutions: You can substitute buttermilk for regular milk to add a slight tang and extra tenderness. Replace the boiling water with hot brewed tea or coffee for a subtle flavor twist.
Room temperature ingredients: Make sure eggs and milk are at room temperature to help the batter mix more evenly and rise better.
Dont overmix: Stir until ingredients are just combined. Overmixing develops gluten, leading to a tougher cake.

Check doneness early: Oven temperatures vary, so start checking your cake at 35 minutes to avoid drying out the edges.

Serving Suggestions

This vanilla sheet cake is incredibly versatile. Frost it with classic buttercream, cream cheese frosting, or a simple dusting of powdered sugar for a lighter option. Top with fresh berries or sliced fruit for a refreshing contrast. For celebrations, add sprinkles or edible flowers for a festive look. It also pairs well with a scoop of vanilla ice cream or a drizzle of chocolate sauce for an indulgent dessert.

Variations

Customize this recipe by adding mix-ins or flavorings. Stir in 1 cup of mini chocolate chips or chopped nuts for texture. Swap half the flour for almond or coconut flour for a nutty nuance, adjusting liquid slightly if needed. Add 2 teaspoons of lemon zest or almond extract instead of vanilla for a different aroma. For a layered cake, bake in two 9-inch pans and stack with frosting or jam.

Storage and Reheating

Store the cooled cake in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 5 days. You can also freeze the cake (unfrosted or frosted) for up to 3 months; thaw overnight in the fridge before serving. To reheat, warm individual slices in the microwave for 10-15 seconds or place the whole cake in a low oven (3006F / 1506C) for 10-15 minutes to freshen it.

Frequently Asked Questions

Can I make this cake gluten-free?
Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Make sure it contains xanthan gum or add 1/2 teaspoon to help with structure. Baking time may vary slightly, so keep an eye on doneness.

Why do you add boiling water to the batter?
The boiling water hydrates the flour fully and helps dissolve the sugar, resulting in a moister, tender crumb. It also slightly thins the batter, which helps the cake rise more evenly.

Can I use oil instead of butter?
Yes, oil makes the cake moister and keeps it fresh longer. Butter adds flavor but can make the cake slightly denser. You can also use melted butter if you prefer that taste, but keep the quantity the same.

How do I know when the cake is done?
Insert a toothpick or cake tester into the center of the cake. If it comes out clean or with a few moist crumbs, the cake is done. Avoid waiting until it comes out completely dry to prevent overbaking.

Can I make this cake ahead of time?
Absolutely. Bake the cake a day or two in advance, store it covered at room temperature or refrigerated, and frost just before serving. This helps the flavors to develop and can make frosting easier.

What frosting pairs best with this vanilla cake?
Classic buttercream (vanilla, chocolate, or cream cheese) complements this cake well. For a lighter option, whipped cream or a simple glaze made from powdered sugar and milk works beautifully. You can also try fruit preserves between layers for added moisture and flavor.

This 9×13 vanilla cake recipe is a reliable, go-to base for countless dessert ideas. Its simplicity allows you to customize and elevate it for any occasion, making it a must-have recipe in your baking repertoire.
