Heavenly White Snack Cake Recipe

Heavenly White Snack Cake

For the Cake

All-purpose flour – 2 ¼ cups (280 g)

Baking powder – 2 ½ teaspoons

Salt – ½ teaspoon

Unsalted butter – ¾ cup (170 g), softened to room temperature

Granulated sugar – 1 ¾ cups (350 g)

Large egg whites – 4, at room temperature

Vanilla extract – 1 teaspoon

Whole milk – 1 cup (240 ml), at room temperature

For the Frosting

Unsalted butter – 1 cup (230 g), softened

Powdered sugar – 4 cups (500 g), sifted

Vanilla extract – 2 teaspoons

Heavy cream or milk – 2 to 4 tablespoons, as needed for consistency

1. Preheat and prepare the pan

Preheat the oven to 350°F (175°C).

Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal.

2. Mix the dry ingredients

In a medium bowl, whisk together the flour, baking powder, and salt.

Set aside.

3. Cream the butter and sugar

In a large mixing bowl, beat the softened butter and granulated sugar together until pale, light, and fluffy (about 2–3 minutes).

4. Incorporate the egg whites and vanilla

Add the egg whites one at a time, beating well after each addition.

Stir in the vanilla extract until fully blended.

5. Combine the wet and dry mixtures

Gradually add the flour mixture to the butter mixture in three parts, alternating with the milk in two parts.

Begin and end with the dry ingredients.

Mix gently until just combined—do not overmix.

6. Bake the cake

Pour the batter into the prepared pan and spread evenly with a spatula.

Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Allow the cake to cool completely in the pan before frosting.

7. Prepare the frosting

In a large bowl, beat the softened butter until smooth and creamy.

Gradually add the powdered sugar, mixing on low speed until incorporated.

Blend in the vanilla extract.

Add heavy cream (or milk), 1 tablespoon at a time, until the frosting is fluffy and spreadable.

8. Frost and serve

Spread the frosting evenly over the cooled cake.

Slice into squares and serve as a light, tender snack cake.
