How to Make It
One little birthday cake, step by step.
- 01
Prepare the oven and pan
Heat the oven to 175°C (350°F). Lightly grease a small round baking dish or ramekin about 10 cm (4 inches) wide and line the bottom with a small circle of parchment if possible.
- 02
Mix the dry ingredients
Add the flour, sugar, baking powder, and salt to a small bowl. Whisk until evenly combined.
- 03
Add the wet ingredients
Add the egg yolk, milk, melted butter, and vanilla extract. Stir gently until the batter is smooth and no dry streaks remain.
- 04
Bake the cake
Transfer the batter to the prepared baking dish and smooth the top. Bake for 18–22 minutes, until the center springs back lightly and a toothpick comes out with a few moist crumbs.
- 05
Cool completely
Let the cake cool in the pan for about 10 minutes, then remove it and allow it to cool completely before frosting.
- 06
Make the frosting
Mix the softened butter, powdered sugar, vanilla extract, and a little milk until the frosting becomes smooth, creamy, and spreadable.
- 07
Create the layers
Once completely cool, carefully slice the cake horizontally into two thin layers. Spread a little frosting between them and place the top layer back in position.
- 08
Decorate the cake
Spread the remaining frosting lightly over the top and sides. Finish with a small scattering of pastel sprinkles on top.
SVI SWEET Tip
Keep the decoration simple and light.
A small single-serving cake looks best with a thin layer of frosting and just a little sprinkle detail. Too much frosting or too many decorations can overwhelm the proportions of the mini cake.
Substitutions
Make it work with what you have.
Sprinkles
Use any small colorful sprinkles you like. Soft pastel sprinkles give the cake a cheerful birthday feel without looking too busy.
Vanilla
Vanilla extract gives the classic birthday cake flavor. A tiny bit of almond extract can be added for a slightly more bakery-style taste.
Frosting
If you want a simpler dessert, you can skip frosting the sides and spread it only between the layers and on top.
Milk
Regular dairy milk or an unsweetened plant-based milk can be used in the batter and frosting as needed.
Storage
Best for a same-day treat.
Room temperature
The frosted cake can be kept in a covered container at cool room temperature for several hours.
Refrigerator
For longer storage, refrigerate the cake in an airtight container for up to 2 days. Let it sit at room temperature for about 15–20 minutes before serving for the softest texture.
Freezing
The unfrosted cake can be wrapped tightly and frozen for up to 1 month. Thaw completely before slicing, frosting, and decorating.
FAQ
A few helpful answers.
Can I make this without sprinkles?
Yes. The cake is still delicious without sprinkles, but they help give it that fun birthday-cake look.
Do I need two pans to make the layers?
No. Bake one small cake, cool it completely, and carefully slice it horizontally into two petite layers.
Can I make the frosting ahead of time?
Yes. The frosting can be mixed ahead and kept covered in the refrigerator. Let it soften slightly at room temperature before spreading.
Can I double the recipe?
Yes. For the most predictable result, divide the doubled batter between two small baking dishes rather than using one deeper pan.
