2 ½ cup flour
2 cups brown sugar
¼ cup margarine
1 teaspoon salt
¼ cup shortening
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon cinnamon
1 teaspoon nutmeg
1 ¼ cup buttermilk [used the milk/lemon juice substitution]
Cut in flour, sugar, salt, shortening, and margarine. Cut until crumbly.
Remove ½ cup and save for topping.
To remaining mixture add baking powder, soda, cinnamon, and nutmeg. Mix thoroughly.
Add buttermilk and eggs, and mix until batter is smooth.
Pour well-greased pan. [used another 13x9 standard pan, since no guidance]
Sprinkle remaining crumbs on top.
Bake at 350 degrees for 20 mins. [NOPE, more like 30-40 minutes. At 20 minutes, it wasn't finished and still soupy in middle. Baked an additional 15-20 mins. until firm on top, and cake tester came out clean.]
In theory, this sounds like a coffee cake. We'll see what the IT boys say it tastes like.
Later post-script: It never made it to IT. The "bread" made a pit stop in my office where it disappeared in two days. I had a single piece, and it was like a denser coffee cake. I may make this again, and add some nuts and diced dried fruit to the batter, and oatmeal to the topping and see how it turns out.
