Prepare your pound cake as directed on box, add cream cheese.
Add in a few drops of pink food coloring, more if you want a deeper color, and mix
Grease a loaf pan with butter then lightly flour it
Pour your pink pound cake batter into your loaf pan
Bake as directed on box (usually around 50 minutes)
Let cool completely for a couple hours or an hour in the fridge
Slice your cake into 1 1/2 inch slices like you would a loaf of bread
Lay your cake slices flat and then use your double heart cookie cutter to cut out your heart shapes
Now mix up another box of pound cake and pour a small amount in the bottom of another loaf pan
Start placing your double hearts onto your batter in the bottom of your pan standing upright (make sure they are close together)
Now pour your remaining batter on top of your hearts
Bake for another 50 minutes
Once your cake is finished baking, let cool completely for a couple hours or an hour in the fridge
Mix together your powdered sugar, milk, and vanilla until you have a creamy icing texture
Remove your cake from your pan and pour your icing onto your cake, letting it drip down the sides
Top off with a handful of micro heart sprinkles
Slice and enjoy!
