In a bowl, combine the wheat flour, cornstarch, and sugar. Mix them together briefly.
Add the butter to the dry ingredients and mix with your hands until a smooth, uniform dough forms.
Wrap the dough ball in plastic wrap. Let it rest before shaping.
Roll the dough into a long log and cut it into small, even-sized pieces.
Take each piece and roll it into a small ball. Place the dough balls onto a baking sheet. Bake until lightly golden (baking time and temperature not specified in the video).
To make the filling, place guava paste and a small amount of water into a saucepan.
Heat the mixture over low heat, stirring continuously until the guava paste melts into a smooth, creamy consistency.
Once the cookies have baked and cooled, pipe the guava filling onto the flat side of one cookie half.
Place another cookie half on top to create a sandwich.
Roll the assembled sandwich cookies in granulated sugar to coat them.
