Trim the edges of the bread slices.

Cut the bread slices in half and use a mold to create two holes in each piece. Leave the base bread intact without holes.

Melt butter in a pan and coat the bread slices evenly, flipping them to absorb the butter.

Toast the trimmed bread pieces and the base bread slices in the butter until golden brown.

Bake the butter-coated bread slices on parchment paper until crispy. Sprinkle sugar on the small trimmed pieces before baking.

Spread strawberry jam on the base bread slices and cover them with the bread slices with holes.

Sprinkle powdered sugar on the small trimmed pieces for decoration.
