Mix together 2 1/4 cup flour, sugar, baking powder and salt in a medium bowl. Cut in the butter/margarine until the mixture resembles coarse crumbs. Make a well in the center and add the beaten egg and milk. Stir until just combined. Only if it’s really too liquidy, add up to another 1/4 cup flour, it should look more like a batter then a dough. It will not come together in a ball like regular hamantaschen dough, so DO NOT try adding flour until it does.
