Mix both types of flour and the baking powder in a large mixing bowl.

In a small bowl, stir the peanut butter with the milk until smooth.

Make a well in the flour mixture and gradually stir in the peanut buttermilk until everything is well mixed.

Shape the dough into 2 smooth balls with your hands. The warmth of the hands helps make the dough easier to work with.

Knead each ball for about 2 minutes on a floured work surface and then roll out the dough to a thickness of 6 - 12 mm.

Cut out biscuits with a cookie cutter and place on a baking sheet covered with baking paper.

Bake the biscuits at around 200 ° C for about 15 minutes.
