Plum Buckle

When I purchase fruit to make jam, I tend to over estimate what is needed.  Although I managed to send some plums home with the jam making parties, I still have a bunch - including 6 cups that were diced for jam and not used.  So, we have this buckle.  Not belt buckle, and you won't find a definition in most dictionaries.  From wisegeek.com:

"Buckle is a dessert which combines fresh seasonal fruit, a rich cake batter, and a streusel topping. The result is a rich, dense cake with a moist crumb which is sometimes compared to coffee cake. It is an excellent summer dessert, and can be served hot or cold, plain or dressed with drizzles of sauce. Making buckle at home is relatively easy, and a great way to use fresh fruit."

  6 Cups Plums, Pitted And Diced                            2 Tsp Almond Extract

  12 Tbl Butter, Softened                                                 --Topping--

  1 1/2 Cup White Sugar                                          1 Cup Sugar

  2 Large Eggs                                                        1/2 Cup Butter, Softened

  3 Cup All Purpose Flour                                        3/4 Cup Old Fashion Oatmeal

  1 Tbl Baking Powder                                             1/4 Cup All Purpose Flour

  1/2 Tsp Salt                                                           1 Tsp Cinnamon

  2 Cup 1% Milk                                                      1/4 Tsp Nutmeg

Preheat oven to 350 degrees.  Grease and flour a 9x13-inch baking dish.

Place the plums into the bottom of the prepared baking dish. In a large bowl, cream together 2/3 cup butter with 1 1/2 cup of white sugar until the mixture is smooth and creamy. Beat in eggs, one at a time, until completely blended.  Stir in 3 cups of flour, the baking powder, and salt. Mix in the milk and almond extract to make a smooth batter. Pour the batter over the plums. Mix topping ingredients together in a bowl to make a crumbly topping; sprinkle over the batter.  Bake in the preheated oven until a toothpick inserted in the center of the cake comes out clean, 50 to 60 minutes.
