Method
In a bowl, cream together the butter and peanut butter until smooth or you can use a chopper like me or hand mixer in easier ways.
Add sugar and salt, whisk until fluffy.
Add the egg and honey, whisk again.
Sift in cake flour and baking powder.
Use a spatula to fold gently until just combined.
Rub the dough mixture lightly with your hands to create small, bean-sized crumbles.
Lightly brush the dinner rolls with water or dip the rolls in the water, then coat with the streusel crumbs.
Bake at 180°C (355°F) for 15–20 minutes until golden.
