Mini Vanilla Cake Recipe: Moist Single-Layer Sponge Tutorial

This mini vanilla cake makes a single 6-inch layer that’s moist, tender and full of vanilla flavor. Frost it with a creamy vanilla buttercream or serve with whipped cream and berries. It serves about 4 people (or 2 with leftovers) — perfect for a small celebration or when you don’t want a lot of leftover cake.

This small vanilla cake has a soft crumb and a buttery vanilla taste that isn’t overly sweet. The batter comes together easily and can be finished simply with a thick vanilla frosting or served alongside fresh berries and whipped cream. Since it’s a single-layer cake, decorating is quick and forgiving, making it ideal for weeknight birthdays or small gatherings.

How to Make Mini Vanilla Cake

Because small-batch cakes are easy to overwork, this recipe uses the reverse creaming method to help prevent overmixing and keep the crumb tender. In contrast to the traditional creaming method (butter and sugar beaten first, then eggs and alternating dry and wet additions), reverse creaming combines the dry ingredients first, then works the butter into the dry mix until the butter is in small pea-sized pieces, and finally adds the wet ingredients. This approach minimizes gluten development and produces a soft, even crumb.

1. Preheat the oven to 350°F (180°C). Line the bottom of a 6-inch (15 cm) round pan with parchment and lightly grease the sides.
2. In a small bowl or liquid measuring cup, whisk together the milk, egg, oil and vanilla until smooth and no egg bits remain.
3. In a separate medium bowl, whisk together the flour, baking soda, salt and sugar.

4. Add the cubed butter to the dry ingredients and beat on low speed until the butter is reduced to small pieces no larger than a pea. The mixture will resemble flour with tiny butter bits.
5. With the mixer on low, slowly drizzle the wet ingredients into the flour-and-butter mixture. Mix just until the batter is smooth and free of lumps; stop as soon as it comes together to avoid overmixing.

6. Pour the batter into the prepared pan and smooth the top. (Optional: wrap the pan in a soaked cake strip to encourage an even, flat top.)
7. Bake for 30–35 minutes, or until the top is set, a toothpick inserted in the center comes out clean or with a few crumbs (not wet batter), and the edges begin to pull away from the pan.

When the cake is cool, top it with a thick and creamy vanilla frosting. The frosting is made by beating butter until smooth, adding sifted powdered sugar with vanilla and a pinch of salt, then adding a little whipping cream (or milk) until you reach your desired consistency. A few drops of food coloring are optional if you want a tinted frosting.

Moist, fluffy and full of vanilla — this small vanilla cake is an easy homemade dessert when you want something simple without a lot of leftovers.

Instructions

Mini Vanilla Cake

1. Preheat the oven to 350°F (180°C). Line the bottom of a 6-inch pan with parchment and lightly grease the sides. The pan sides should be at least 2 inches (5 cm) high.
2. Whisk the egg, oil, vanilla and milk together in a small bowl until smooth and no egg bits remain. Set aside.
3. Whisk the flour, baking soda, salt and sugar together in a medium bowl.
4. Add cubed butter to the flour mixture and beat on low until the butter is in pea-sized pieces.
5. With the mixer on low, drizzle in the wet ingredients and mix only until the batter is smooth and free of lumps.
6. Pour the batter into the prepared pan and bake in the middle of the oven for 30–35 minutes, until a toothpick comes out clean and the edges pull away slightly.

Vanilla Frosting

1. Beat the butter until smooth and creamy.
2. Add 1 cup powdered sugar, vanilla, salt and optional food coloring. Start mixing on low until combined.
3. Beat in the remaining powdered sugar a little at a time, alternating with a teaspoon of whipping cream or milk until you reach the desired sweetness and consistency.
4. Invert the cake onto the serving plate and frost the top of the cooled cake.

Notes

1. Flour: Measure flour accurately to avoid a dry cake. Whisk first, spoon into a dry measuring cup and level, or use a scale for grams.
2. Storage: Store in an airtight container at room temperature for up to 2 days, or refrigerate up to 4 days. Cake is best the day it’s baked.
3. Nutrition: Nutrition info is an estimate per slice (1 of 4) including frosting.
