Step‑by‑Step Instructions for Rhubarb Streusel Coffee Cake

Step 1: Prepare the Rhubarb
Begin by preheating your oven to 350°F (175°C). While it heats, wash and trim approximately 2 cups of fresh rhubarb stalks, chopping them into bite-sized pieces. This tart fruit will add delightful flavor to your Moist Rhubarb Streusel Coffee Cake, so ensure they’re nice and vibrant before moving on.

Step 2: Make the Streusel Topping
In a medium bowl, combine ½ cup of granulated sugar, ½ cup of all-purpose flour, 1 teaspoon of ground cinnamon, and ½ cup of cold butter, diced into small cubes. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs. This crunchy topping will provide a wonderful texture contrast to your coffee cake.

Step 3: Combine the Wet Ingredients
In a large mixing bowl, whisk together 2 large eggs and 1 cup of granulated sugar until the mixture is fluffy and pale, which should take about 2-3 minutes. Gradually blend in ½ cup of melted butter, 1 teaspoon of vanilla extract, and ½ cup of sour cream until fully incorporated. This rich base sets the stage for the ultimate Rhubarb Streusel Coffee Cake.

Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of baking soda. Gradually add this dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix; a few flour streaks are perfectly fine for your coffee cake’s tender crumb.

Step 5: Layer the Ingredients
Grease a 9-inch square pan or a similar-sized baking dish. Pour half of the coffee cake batter into the prepared pan, spreading it evenly. Next, layer half of the chopped rhubarb over the batter, then add the remaining batter on top. Finish by scattering the rest of the rhubarb over the cake, followed by the crumbly streusel topping. This beautiful layering creates bursts of flavor throughout.

Step 6: Bake the Cake
Place your assembled Rhubarb Streusel Coffee Cake in the preheated oven and bake for 45-50 minutes. Keep a close eye on your cake; it’s ready when a toothpick inserted into the center comes out clean, with a golden-brown color on top. The aroma will fill your kitchen, promising a delightful treat is on the way.

Step 7: Cool and Serve
Once baked, remove the cake from the oven and let it cool in the pan for about 15 minutes. This cooling step allows the flavors to meld beautifully. If desired, dust with powdered sugar or drizzle with a simple vanilla glaze before cutting into squares. Now your delicious Rhubarb Streusel Coffee Cake is ready to be served warm!

Rhubarb Streusel Coffee Cake Recipe FAQs

When you’re ready to enjoy, thaw the slices in the fridge overnight and reheat gently in the microwave or oven for that delightful freshly baked taste.

What if my cake seems too dense or isn’t rising?
Very! If your Rhubarb Streusel Coffee Cake turns out dense, it could be due to overmixing the batter or not beating the eggs long enough. Beat the eggs until fluffy and combine the wet and dry ingredients just until mixed—aim for a tender crumb!

Are there any dietary considerations I should keep in mind?
