Toast the flour in a large frying pan over low heat, stirring continuously with a rubber spatula until the flour changes color from white to light brown, approximately 10-12 min.
Transfer the toasted flour to a mixing bowl. Add the rest of the dry ingredients and mix together. Set aside.
Melt the butter in a saucepan over medium heat, steep pandan leaves while butter is melting.
Remove the pandan leaves. Add the warm melted butter into the dry ingredients then mix until incorporated. Add pandan extract and mix.
While the mixture is still warm, form desired polvoron shapes by packing the mixture (about 1 tablespoon each) into the polvoron molder or plunger cutter (Don’t press the mixture in too hard or it will get stuck in the mold!).
Cool for at least 1 hour in the fridge or until firm.
