Mini Heart Cakes are the perfect way to celebrate Valentine's Day...or any other day you want someone to feel extra loved! They're simple to make and don't require a specialty cake pan...which will save you money and cupboard space!
If your cupcakes tend to sink or spread over the edges, try heating your oven to 400º and bake for 12-14 minutes. This higher heat will force your cupcakes up more quickly as they bake, preventing the batter from spilling over the sides or sinking in the middle. If your cupcakes turn out well at 350º, then stick with that! This higher heat method helps my cupcakes bake to just the right height for these cakes.
Sometimes I add a cup of chocolate chips to the batter (which I did the day I photographed these cakes). They can stick to the bottom of the cake pan, so consider using parchment paper to remove it more easily from the pan.
