(Original recipe in German: here)
100g soft butter
150g peanut butter (I used crunchy)
1 large egg
For the decoration:
store bought dark chocolate glaze
nonpareilles or chocolate sprinkles
In a bowl, mix butter and peanut butter with an electric hand mixer until soft. Then, add sugar and beat until combined. Add the egg and beat. When all is well combined, sift in the flour. Beat with the electric mixer first, then knead with your hands. Form a ball, flatten a little and cool in de refrigerator for at least 30 minutes.
Preheat the oven to 180°C. Line two baking trays with parchment paper. Roll out the dough until about 4mm thick. Cut out cookies. Put the cookies on your tray and bake for about ten minutes. Cool on a wire rack.
When the cookies have cooled completely, decorate with chocolate glaze and chocolate sprinkles or nonpareilles… Whatever you feel like. I melted the chocolate glaze according to the instructions on the packaging and brushed the glaze onto the cookies. Then, I covered the cookies with chocolate sprinkles.
