Step‑by‑Step Instructions for Rhubarb Sour Cream Coffee Cake
Step 1: Prepare the Streusel
In a mixing bowl, combine all-purpose flour, brown sugar, cinnamon, and salt. Cut in cold unsalted butter using a pastry cutter or your fingertips until the mixture resembles coarse crumbs. This buttery streusel will add a delicious crunch to your Rhubarb Sour Cream Coffee Cake. Once mixed, refrigerate the streusel for at least 15 minutes to ensure it stays crumbly when baked.
Step 2: Mix the Batter
In a large bowl, cream together unsalted butter and granulated sugar until light and fluffy, about 3-5 minutes. Add in eggs, a scoop of sour cream, and vanilla extract, blending until smooth. Gradually sift in the dry ingredients: flour, baking powder, baking soda, and salt. Mix just until combined to keep the cake tender, ensuring your Rhubarb Sour Cream Coffee Cake remains moist and fluffy.
Step 3: Prepare the Rhubarb
If using fresh rhubarb, trim it and chop it into small pieces. In a separate bowl, toss the chopped rhubarb with a sprinkle of granulated sugar to balance its tartness. This step is essential for creating a harmonious flavor in your cake. Set the sugar-coated rhubarb aside while you assemble the other cake components.
Step 4: Layer in the Pan
Preheat your oven to 350°F (175°C) and grease a 9-inch square baking pan. Spread half of the rhubarb coffee cake batter evenly in the bottom of the pan, smoothing it with a spatula. Sprinkle the prepared rhubarb evenly on top, followed by dollops of the remaining cake batter. Finally, top it off generously with the chilled streusel mixture to create that delightful topping.
Step 5: Bake
Place the baking pan in the center of your preheated oven. Bake the Rhubarb Sour Cream Coffee Cake for 40-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out with moist crumbs. Keep an eye on it; if the top browns too quickly, tent it loosely with aluminum foil to prevent burning.
Step 6: Cool and Slice
Once baked, remove your cake from the oven and let it cool in the pan for at least 20 minutes. This cooling time allows the layers to set, making slicing easier. Once cooled, transfer the Rhubarb Sour Cream Coffee Cake to a wire rack to cool completely, or serve warm for a delightful treat.

Make Ahead Options
These Rhubarb Sour Cream Coffee Cakes are perfect for meal prep enthusiasts! You can prepare the streusel topping and the cake batter up to 24 hours in advance. For the streusel, mix all the dry ingredients and butter, then refrigerate in an airtight container to retain its texture. You can also toss the chopped rhubarb with sugar and refrigerate it overnight. When you’re ready to bake, simply layer the chilled batter and rhubarb in the pan, top with the stored streusel, and bake as directed. This way, you’ll have a delicious coffee cake with minimal effort, ensuring that even busy mornings can begin with a delightful homemade treat!
