Preheat your oven to 350°F (175°C) to ensure it’s hot and ready for baking.

Grease and flour two heart-shaped cake pans.

Cream together the butter and sugar in a large bowl until the mixture is light and fluffy.

Add eggs one at a time, mixing well after each addition.

Stir in the milk and vanilla extract.

Combine the flour, baking powder, and salt in a separate bowl; then gradually add this dry mixture to your wet ingredients.

Divide the batter equally into the prepared heart-shaped pans.

Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

Cool the cakes completely in the pans for about 10 minutes, then gently turn them out onto a wire rack to cool completely.

Frost the cooled cakes generously with buttercream and decorate with heart-shaped sprinkles.
