Melt the butter in a microwave safe bowl until melted, about 30~40 seconds.
Add the condensed milk, milk powder, almond powder to the melted butter. Stir thoroughly with a wooden spoon until well combined.
Microwave this mixture for 1 minute. Remove from the oven and stir well.
Repeat this process of microwaving for 1 minute and stirring 2 more times. So I microwaved for a total of 3 minutes.
Mixture should have thickened and dried out by this point.
Cool the mixture until it is easy to handle, about 10~15 minutes.
Take about 1 tablespoon of mixture and roll into smooth balls and flatten them to make discs. If you want to make them look fancy, use a small cookie cutter to lightly emboss a design on top.
