How to Make Rhubarb Coffee Cake

Step 1: Prepare the Streusel Topping
In a medium bowl, whisk together the flour, brown sugar, granulated sugar, and cinnamon. Then, add the cold, cubed butter and use a pastry blender or your fingers to cut the butter into the dry ingredients until the mixture resembles coarse crumbs. This step is crucial for achieving that perfect streusel texture.
Alternatively, you can use a food processor to pulse the ingredients until they come together. Place the streusel topping in the refrigerator while you prepare the cake batter to keep the butter cold and the topping crumbly.
Step 2: Make the Cake Batter
Preheat your oven to 350°F (175°C) and grease and flour a 9×13 inch baking pan. In a large bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures that the leavening agents are evenly distributed throughout the batter.
In a separate bowl, cream together the softened butter and granulated sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract, followed by the sour cream.
Step 3: Combine the Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix the batter, as this can lead to a tough cake. Overmixing can also affect the final texture of the cake.
Gently fold in the chopped rhubarb. Pour the batter into the prepared baking pan and spread it evenly.
Step 4: Add the Streusel and Bake
Sprinkle the prepared streusel topping evenly over the batter. Bake for 35-45 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. This resting period allows the cake to set properly and makes slicing easier.
Step 5: Serve and Enjoy
Once cooled, slice and serve. This delicious cake is best enjoyed fresh, but it can also be stored for later. Serve this delightful dessert with a cup of coffee or tea.
For those who love a bit of tang, consider adding a drizzle of lemon glaze to enhance the flavor. If you are looking for other delicious recipes, consider making some coffee cake variations.
Tips for the Best Rhubarb Coffee Cake
Here are some helpful tips to ensure your rhubarb coffee cake turns out perfectly every time. These tips will help you avoid common mistakes and create a delicious and visually appealing cake for your next gathering.
Rhubarb Preparation
When preparing the rhubarb, be sure to trim off the leaves, as they are toxic. Chop the stalks into roughly 1-inch pieces for even distribution throughout the cake.
For a more intense rhubarb flavor, you can macerate the chopped rhubarb with a tablespoon of sugar for about 15 minutes before adding it to the batter. This step draws out some of the rhubarb’s juices, intensifying its flavor and softening the texture.
Streusel Secrets
Make sure your butter for the streusel is cold. This helps create those lovely, crumbly pieces that give the topping its texture.
Don’t overmix the streusel. You want it to resemble coarse crumbs, not a smooth paste.
Baking and Doneness
Bake the cake until a toothpick inserted into the center comes out clean. This indicates that the cake is fully cooked.
Keep an eye on the streusel topping as it bakes to prevent it from burning. If it starts to brown too quickly, you can loosely tent the cake with aluminum foil during the last part of the baking time.
Flavor Enhancements
For an extra layer of flavor, consider adding a teaspoon of ground cardamom or nutmeg to the cake batter. These spices complement the tartness of the rhubarb beautifully.
You can also add a hint of orange zest to the batter for a brighter flavor. This pairs well with rhubarb and adds a fresh, citrusy note.
Variations and Serving Ideas

This rhubarb coffee cake is delicious on its own, but you can also customize it with different flavors and serving ideas. Here are a few ideas to get you started. Experimenting with different ingredients and flavors can create a unique and delightful dessert.
Coffee Cake with Rhubarb Variations
Add a layer of cream cheese frosting on top of the cake after it has cooled for a sweeter, more decadent treat. You can also add some vanilla extract to the frosting to enhance the flavor.
Incorporate other fruits like strawberries or raspberries into the cake batter for a mixed berry variation. This adds more color and flavor to the cake.
Serving Suggestions
Serve the cake warm or at room temperature. It’s fantastic with a dollop of whipped cream or a scoop of vanilla ice cream.
For a breakfast treat, serve it with a side of fresh fruit and a cup of coffee. This makes a perfect combination for a sweet start to your day.
Make-Ahead and Storage Tips
This rhubarb coffee cake is a great make-ahead dessert. You can prepare it the day before, or even freeze it for later.
Make-Ahead Instructions
You can make the cake and streusel topping the day before you plan to serve it. Store the streusel in the refrigerator, and the unbaked cake batter in the refrigerator as well.
The next day, assemble and bake the cake as directed. This helps you save time and effort.
Storage Tips
Store leftover cake in an airtight container at room temperature for up to 3 days. This keeps the cake fresh and moist.
For longer storage, you can freeze the cake. Wrap it tightly in plastic wrap and then in aluminum foil, and freeze for up to 2 months. You can also freeze individual slices for a quick treat.
Common Mistakes to Avoid
Here are some common mistakes to avoid when making rhubarb coffee cake. Avoiding these pitfalls will help you achieve a perfect cake every time. These tips will help you avoid common baking errors.
Overmixing the Batter
Overmixing the cake batter can result in a tough cake. Mix the wet and dry ingredients just until combined.
Overmixing develops the gluten in the flour, leading to a less tender final product. Stop mixing as soon as the ingredients are combined.
Incorrect Oven Temperature
Using the wrong oven temperature can affect the cake’s texture and how it bakes. Always preheat your oven to the correct temperature before baking.
If your oven runs hot or cold, adjust the temperature accordingly to ensure even baking. A properly heated oven is essential for a well-baked cake.
Not Measuring Ingredients Properly
Incorrectly measuring ingredients, especially flour, can alter the cake’s texture. Use the spoon and level method, or weigh your ingredients for the most accurate results.
Too much flour can make the cake dry and dense, while too little can make it too soft. Accurate measurements are key to a successful bake.
