Combine the butter, sugar, and flour using a pastry blender. I use this because I do not have a stand mixer (again, not a baker!). It works great and gives you an upper arm workout at the same time! (2) Once you have only little clumps of butter, add the milk, cinnamon, oats and almond extract. Continue to mix well. The crumble will (surprise) be crumbly yet moist.
