This is the traditional non-yeasted Irish soda bread passed down in my family from my Irish grandfather. It's so good as a breakfast, snack, or even dessert.
Grease two large loaf pans. Preheat oven to 350 degrees.
Combine flour, sugar, baking powder, baking soda, and salt in large mixing bowl. Cut in butter until pea sized chunks appear. Add raisins and stir to distribute.
In a liquid measuring cup, add egg to buttermilk and whisk gently until the egg is lightly beaten. Add mixture to dry ingredients, and stir gently until just combined.
1 egg, 2 1/2 cups buttermilk
Turn into loaf pans, and cut across the top lengthwise. Bake at 350 degrees for about 50-60 minutes until tester comes out with crumbs.
Butter loaf top when it comes out of the oven. Lay on pan its side for a few minutes, then lay on the opposite side for a few minutes to loosen edges. After both sides, remove from the pan and continue cooling on a wire rack.
