Method:

1. Preheat oven to 350⁰F (180⁰C). Lightly butter (or coat with an oil spray) a 9 inch springform pan.
2. Prepare Streusel Topping: In a bowl, combine brown sugar, nuts, cinnamon and oatmeal. Stir in melted butter; mix until crumbly. Set aside.
3. Prepare Cake:  In a large mixer bowl, with a stand mixer, beat butter and brown sugar until light and fluffy. Beat in eggs, one at a time.   Beat in the vanilla.
4. In a separate bowl, mix flour, baking soda, baking powder, salt, and spices.
5. Add the flour mixture to the butter mixture alternately with the buttermilk, beginning and ending with the flour mixture.
6. Fold in chopped rhubarb and apple pieces.
7. Spread in prepared pan; Sprinkle with the streusel topping.
8. Bake for 55-70 minutes, or until an inserted cake tested comes out clean and dry. Let cake cool for 5-10 minutes before releasing the spring-form pan. If you find that the cake is browning too quickly, loosely cover with some foil partway through the baking time.
9. Serve warm, or at room temperature. Whipped cream is always a great topping!
