Cut 1 banana into ΒΌ-inch slices and spread a thin layer of nut or seed butter on half of the slices.
Put the other half of the slices on top to make little sandwiches, then place in freezer until frozen.
Melt 1-2 Tbsp organic 70-80% dark chocolate chips and dip one end of the frozen sandwiches.
Store in freezer.
