Using your 3" heart cookie cutter stamp out pizza crust into mini heart pizza crusts.
Spoon a couple of spoonfuls of sauce onto the crust.
Sprinkle top with shredded mozzarella cheese.
Add 3-4 mini pepperoni hearts on top.
Line a baking pan with parchment or foil. Bake your mini pizzas for 10-12 minutes in a preheated 400 degree oven or until cheese is melted and bubbly.
Immediately after pulling out of the oven, add 3-3 mini cheese hearts so they can melt from the residual heat but still keep their shape.
