Slice each thick piece of bread horizontally, stopping before you cut it all the way through so one side stays joined. Press inside the bottom half to create a little pocket. Spread condensed milk along the edges to act like glue. Spoon in 2-3 tablespoons of your filling into the bread pocket. Fold the top back over and press the edges softly to seal it. Repeat for all your bread slices.

Warm up a tablespoon of butter in a sticky-free frying pan on medium heat. Dip one stuffed toast into the batter, soaking both sides for about 20 seconds. Let the extra drip off, then put it in your hot pan. Cook for approximately 2 minutes on each side, carefully flipping, and adjust the heat to avoid burning. Move it to a plate when it's done. Repeat for all slices, adding butter as needed after each one.

Serve straight away with more butter and condensed milk if you like. Drizzle condensed milk on top and enjoy while it's still warm.
