Make It
Step 1
Preheat oven to 375° F. Line a large baking sheet with foil.
Step 2
Pour 1 teaspoon of sweetened condensed milk in a line in center of each empanada disc. Add 8 morsels (about 1 teaspoon) on top of milk. Add 6 pieces of banana on either side of morsels. Carefully fold in half and crimp edges with fingers to seal. Place empanadas on prepared baking sheet; brush with beaten egg.
Step 3
Bake for 15 to 20 minutes or until golden. Serve warm and dusted with powdered sugar, if desired.
