Cut off the crusts of the bread

Flatten the bread with a cup or a rolling pin

Put your spread on one piece of bread (do not put too much)

Put the other slice on top - like a sandwich

Flatten the edges together with a fork

Put another spread on top

Put the cookies in a bag and crush them

Sprinkle the smashed cookies on top of the spread

Finished! (＾∀＾)ﾉ
(I also put sprinkles on mine)
