- 225g butter, at room temperature, or baking spread
- 225g caster sugar
- 4 large eggs
- 225g self-raising flour
- 2 teaspoons baking powder
- 1 teaspoon vanilla extract
For the filling and decoration:
- 4 tablespoons strawberry jam

Step-by-Step Guide to Making Spotty Cake
Step 1: Preheat the oven and prepare the tins. Preheat the oven to 180C (160C fan / Gas 4). Grease and line two 20cm round sandwich tins with baking paper.
Step 2: Mix the sponge. Put the butter, caster sugar, eggs, self-raising flour, baking powder and vanilla extract into a large bowl. Beat until combined and soft, with a dropping consistency. Do not overmix.
Step 3: Bake until golden. Divide the mixture equally between the tins and level the tops. Bake on one shelf for about 25 minutes, until golden, springy to touch, and shrinking slightly from the sides.
Step 4: Fill and ice. Leave the sponges in the tins for 5 minutes, then turn them out onto a wire rack to cool completely. Spread jam on one sponge. Beat the softened butter, icing sugar and milk into a smooth buttercream, and spread half on the other sponge, or over the jam. Sandwich the cakes together.
Step 5: Add the spots. Spread the remaining buttercream over the top of the cake. Press colourful chocolate sweets into the icing in a spotty pattern, and press a few around the sides if you like. Dust lightly with icing sugar, if you like, and serve in slices.
Cook’s Secrets for a Perfect Spotty Cake
Use butter at room temperature, so the sponge mixes smoothly and rises well. Do not overmix once the flour is in, as this can make the cake heavy. Bake both tins on the same shelf, so they cook evenly. Cool the sponges completely before icing, or the buttercream will melt. Place the sweets just before serving if you want them to stay crisp and bright. For a neater finish, chill the iced cake for 15 minutes before adding the spots.
