In large bowl, mix 2 1/4 cups flour and 3/4 cup sugar. Cut in butter, using pastry blender (or pulling 2 table knives through mixture in opposite directions), until mixture looks like coarse crumbs. Reserve 1 cup of the crumb mixture. Stir baking powder, baking soda, salt, sour cream, almond extract and egg into remaining crumb mixture. Spread batter over bottom and 2 inches up side (about 1/4 inch thick) of pan.
