Classic coffee cake with a buttery cinnamon streusel, optional fruit or jam filling, and a simple drizzle of icing—perfect for coffee or tea.
For the Cake:
1/2 cup sour cream
2 eggs
1/2 cup butter, softened
1 tsp vanilla extract
3/4 cup sugar
1/2 cup milk
1/4 tsp salt
1 1/2 tsp baking powder
1/4 tsp baking soda
1 1/2 cups all-purpose flour
For the Streusel:
3 tbsp butter, melted
1/2 cup brown sugar
2 tsp cinnamon
1/2 cup flour
Optional: 1/4 cup chopped nuts
Filling (optional):
1 1/2 cups fresh or frozen fruit, diced or 8 oz jam
Icing (optional):
2-3 tbsp butter, softened
1/2 cup powdered sugar
1-2 tsp milk
Heat the oven to 375°F and get your baking dish ready—grease it or line it with parchment.
Mix the batter:
Beat your eggs, then add sugar, milk, butter, and vanilla. Sprinkle the flour over the top, then add baking powder. Mix gently until it’s all combined, being careful not to overwork it.
Add the filling (if using):
Pour half of the batter into the pan, spread your fruit or jam on top, then gently add the rest of the batter over it.
Make the streusel:
Melt the butter in a small bowl, then stir in brown sugar, cinnamon, flour, and nuts if you like. Sprinkle it over the cake, then poke it gently into the batter in a few random spots—it helps the flavors swirl together.
Bake:
25–30 minutes, until a toothpick comes out with moist crumbs. Be careful not to overbake, or it will dry out.
Optional icing:
Mix butter and powdered sugar, add a little milk to thin, and drizzle over the cooled cake.
