Beat together the butter, sugar, egg and Dr. Oetker Madagasan Vanilla Extract.
Next incorporate the flour and the Dr. Oetker baking powder, along with the Dr. Oetker Bright & Bold Sprinkles. Mix together to form a dough.
Shape the dough into a log (it doesn't need to be perfect) and wrap in cling film.
Chill the dough in the freezer for 30-40 minutes. Remove from the freezer and slice into 16 pieces.
Put the slices on a greased baking sheet and bake 8-9 minutes at 200C (180C Fan Oven). You will know when they are ready when they are a nice golden brown on the bottom.
Allow the cookies to cool completely. Then scoop 1-2 tablespoons of ice cream between two cookies and sandwich together. Roll in Dr. Oetker Sprinkles of your choice and then freeze 30 minutes before serving. Enjoy!
