Stir 200g of boiled and mashed sweet potatoes and 40g of butter in a bowl

Instead of sugar, I put in a spoonful of powdered milk. It doesn't matter

Separate only the yolk from the egg. (Please handle the whites comfortably. ^^)

Put the yolk in a bowl and mix it

If you add 3 drops of vanilla oil, it smells really good

Sift 200g of flour and mix in well shape

If the dough doesn't stick to the spatula or hands, put it in a plastic bag

Roll it 5m thick and put it in the refrigerator for at least 1 hour

Sprinkle with a little flour and shape with cookie molds, small cups or plates

I sprayed too much and after baking it, there were so many powder marks

Put the remaining dough back together, cover it with plastic, and push it with a rolling pin. (I pushed it back in a plastic pack because it was time for the baby to go to sleep and kept it frozen.) ^^) Return cookies to the air fryer at 160 degrees for 20 minutes

I pressed the cookie mold too gently and put in too much baking powder, so they're swollen

It's perfect even if you give it to Tidings-Rus-Crow ^^
