Sorry its not coffee cake. I couldn't find one for "coffee cake", but this recipes calls for fresh raspberries and sounds REALLY good. Hope this helps some. Also, I DID find a recipe for raspberry coffee cake, but it called for raspberry jam. Let me know if you need it too.

Raspberry Upside-Down Cake

2 cups fresh raspberries
2/3 cup butter, softened
2/3 cup sugar
3 eggs
2 cups flour
1 Tbsp. lemon juice
1 tsp. vanilla extract
2 tsp. baking powder
pinch of salt
2/3 cup milk
Powdered sugar

Coat a 9-inch square baking pan with non-stick cooking spray.

Spread half the raspberries along the bottom of the baking pan.

Combine butter, sugar, eggs, flour, lemon juice, vanilla, baking powder, salt and milk and mix well. Fold in the other half of the raspberries and pour over raspberries in the pan.

Bake for 45 minutes at 350. Allow to cool and invert cake onto a platter. Sprinkle with powdered sugar. Slice and serve.
