Method
Preparation
- Heat the oven to 350°F / 175°C and lightly grease a 9x13-inch baking pan.
- Blend the flour, 3/4 cup sugar, and softened butter together until coarse crumbs form.
- Set aside 1 cup of the crumb mixture to use as the topping.
- Combine the remaining crumb mixture with baking powder, baking soda, salt, sour cream, and 1 egg, mixing until the batter is mostly smooth.
- Spread the batter evenly into the prepared 9x13-inch pan.
Filling
- Beat the softened cream cheese with 1/4 cup sugar and 1 egg until smooth.
- Spread the cream cheese mixture over the batter layer in the pan.
- Add raspberry jam over the cream cheese layer and gently swirl it with a knife to create a marbled effect.
Baking
- Sprinkle the reserved crumb mixture evenly over the top of the cake.
- Bake for 45 to 55 minutes, until a knife inserted into the cake comes out clean.
- Allow the coffee cake to cool for at least 15 minutes before slicing and serving.
Notes
Use butter and cream cheese at room temperature to create a smoother filling and a more evenly textured batter.
