Preheat oven to 350°F.
In a large bowl combine the butter and sugar. Stir until combined. Add in the eggs one at a time, mixing to combine between each one. Stir in the vanilla extract.
In a smaller mixing bowl combine the flour, baking powder and salt. Stir with a fork to combine. Slowly add to the wet ingredients and stir until combined.
Line a 10 inch cast iron skillet with parchment paper. Pour the batter into the skillet and smooth out.
Top with the sliced peaches and raspberries.
In a small bowl combine the light brown sugar, flour and butter. Stir until combined and crumbled. Spread over the top of the cake.
Bake at 350°F for about 45 mins or until a toothpick inserted into the center comes out clean.
Remove from oven and allow to cool in the skillet for about 10-15 minutes. Grabbing the edges of the parchment paper remove the cake from the skillet. Set on a tray or plate.
In a small bowl stir together the softened cream cheese and milk until smooth. Add the powdered sugar and vanilla. Stir until combined. Drizzle over the cake. Serve and enjoy!
