How do you make Rhubarb Sour Cream Coffee Cake?

Making Rhubarb Sour Cream Coffee Cake is straightforward and rewarding. Follow these steps for a delicious outcome.

Step 1: Preheat your oven to 350°F (175°C) and grease a 9-inch square baking pan.

Step 2: In a small bowl, combine all ingredients for the streusel: flour, brown sugar, cinnamon, and salt. Add melted butter and mix until crumbly; set aside.

Step 3: In a large mixing bowl, cream together softened butter and sugar until the mixture is light and fluffy.

Step 4: Beat in eggs one at a time, mixing well after each addition. Stir in vanilla extract and sour cream until thoroughly combined.

Step 5: In a separate bowl, whisk together flour, baking powder, baking soda, and salt. Gradually fold the dry ingredients into the wet mixture, mixing until just combined.

Step 6: Toss chopped rhubarb with sugar and flour, then fold half of the cake batter into the greased pan.

Step 7: Sprinkle the rhubarb mixture evenly over the first layer of batter, then carefully spoon the remaining batter on top and spread it evenly.

Step 8: Top the cake with the prepared streusel mixture, spreading it out evenly.

Step 9: Bake for 40 to 50 minutes, or until a toothpick inserted comes out with moist crumbs.

Step 10: Allow the cake to cool for at least 20 minutes before slicing and serving.
