a luscious coffee cake with a filling of raspberries and raspberry jam running through a tender cake.
Preheat oven to 350F. Spray a 9" cast iron skillet with cooking spray.
IN a medium bowl, whisk together the flour, sugar, salt and cinnamon. With a mixer at medium speed, beat in butter until crumbly (or mi by hand with a fork). Stir in the nuts. Set aside.
In a large bowl, using your stand mixer, beat butter and sugar until light and fluffy, about 3-4 minutes. Add eggs, one at a time, to incorporate. Beat in Vanilla.
In a medium bowl to the side, mix together the flour, baking powder, and salt. Reduce mixer speed to low, and gradually add flour mixture with the butter - add alternately beginning and ending with the flour mix. Mix until just combined after each addition.
In a small bowl, mash the raspberries slightly with a fork or pastry cutter, then stir in the jam. Set aside.
Spread 3/4's of the batter into the skillet. Spread the raspberry mix over it. Top with the remaining batter, spreading to the edges (if possible), then sprinkle with the topping.
Bake 50-55 minutes until a wooden pick comes out clean. Cover with foil if needed to prevent excessive browning. Allow to cool.
in a small bowl, mix together the sugar and cream until smooth, and drizzle over a cooled cake.
