Use a heart shaped cookie cutter to cut out a heart from the bread.
Spread 2 tablespoons of filling on one slice of bread and top with second piece of bread.
Place bottom of pretzels in between the slices of bread for the ears.
Place a tiny dollop of filling on the bottom of the chocolate chips and one side of the raspberry or blueberry to adhere to the bread for the eyes and nose.
Notes
Instead of tossing the crusts of the sandwich bread after cutting out the heart, try making these Cinnamon Toast Pinwheels with them. Never waste any sandwich bread again with this amazing little hack.
