GRANDMAS ONE BOWL CRUMB CAKE

Steps:

• 1. Preheat oven to 350. In a large bowl, whisk together the sugars, flour, baking soda and powder, the salt, nutmeg and cinnamon. Cut the butter in either with your fingers or a pastry cutter. Remove 1/2 cup of this to save as topping.
• 2. Here I set aside some topping. Nuts are optional. I added them to both the batter and the topping.
• 3. Oh no, not enough buttermilk! But never fear, there are always options. I could just fill the rest with milk, although it will be a thinner batter. Or I could add a blob of sour cream and then top off with milk. As it happens, I have some plain yogurt, "European Style" which means runny. So I just put about 1/4 cup of that in with the buttermilk and then topped off with the milk. Works like a charm. As long as you get about the desired thickness of liquid. If I had to make it with just milk, I would use less, and I would have used more baking powder and less of the baking soda. Baking soda works best with acidic liquids like buttermilk and yogurt. Baking powder is best when used with just milk.
• 4. Add the egg to the measuring cup holding the buttermilk, whisk and add to the flour mixture. Stir with a danish whisk or wooden spoon until just mixed.(If the batter seems just too thick, add 2 tablespoon or more of milk to it.) Pour into a greased 9 x 13 baking pan.
• 5. Sprinkle the reserved topping over the crumb cake batter. Optionally, you can top with chopped nuts as well. Bake until the cake springs back when pressed with a finger and is golden brown. (About 35 minutes)
