Using the hand mixer, stir the margarine, peanut butter and sugar until creamy. Then add the flour and baking powder and stir diligently. Chop peanuts and add to them.
With the help of 2 teaspoons, place small portions with a large gap (really large gap, they run very apart!) On a baking sheet lined with baking paper and press them flat.
Bake at 180 ° for about 10 minutes. Bake at 160 ° with convection.
Decorate with a peanut or chopped peanuts and sugar before baking.
