Hot Cross Biscuits

Preheat oven to 400°F. Line a sheet pan with parchment paper.
In a large bowl combine flour, sugar, baking powder, baking soda, salt, cinnamon, and allspice.
Add butter and cut into dry ingredients with a pastry blender or knife until butter is the size of small peas. Stir in raisins.
Combine egg and buttermilk and pour over the cut butter mixture. Use a spatula or spoon to combine mixture, then dump out on to a clean surface and use your hands to bring it completely into a ball. It's okay if it's a little craggy.
Roll or pat to about 1 inch thick and cut with a 2 or 3-inch glass or biscuit cutter.
Place on the prepared sheet pan and bake until tops and bottoms are lightly golden, about 15-18 minutes (smaller biscuits will need less time). Let cool while you make the icing.
Combine powdered sugar and milk or cream to make a thick icing. It should be thick enough to hold it's shape.
Using a spoon or pastry bag fitted with a plain tip, drop icing over the biscuits in the shape of a cross. Let icing set up before serving.
