How to Make Rhubarb Streusel Coffee Cake

Step 1: Prepare the Rhubarb

Wash and chop fresh rhubarb into bite-sized pieces, ensuring they’re evenly sized so they distribute well throughout the batter and bake consistently.

Step 2: Make the Streusel Topping

Combine sugar, cinnamon, flour, and cold butter to create a crumbly mixture. Use your fingers or a pastry cutter to blend until it resembles coarse crumbs.

Step 3: Mix the Batter

Whisk together eggs and sugar until light and fluffy, then slowly blend in melted butter, vanilla extract, and sour cream for moisture. Gradually fold in the dry ingredients until just combined.

Step 4: Assemble the Cake

Pour half of the batter into a greased pan, sprinkle half the rhubarb evenly on top, then spread the remaining batter over it. Top with the rest of the rhubarb, followed by the streusel topping.

Step 5: Bake Until Golden

Bake at 350°F (175°C) for about 45-50 minutes, or until a toothpick inserted in the center comes out clean and the streusel is golden brown and crunchy.

Pro Tips for Making Rhubarb Streusel Coffee Cake

• Use fresh rhubarb: Frozen rhubarb can be watery; fresh rhubarb ensures perfect texture and flavor.
• Chill your butter: Cold butter creates a flakier streusel topping.
• Don’t overmix the batter: Overmixing can lead to a dense cake instead of a tender crumb.
• Adjust bake time for your oven: Start checking for doneness at 40 minutes to avoid drying out the cake.
• Let it cool before slicing: This helps the cake set and prevents crumbling.

How to Serve Rhubarb Streusel Coffee Cake

Freezing

Warm slices gently in a microwave or oven at low heat to bring back that just-baked aroma and soften the texture without drying it out.

FAQs

Can I use frozen rhubarb instead of fresh?

Fresh rhubarb is best for this cake because it holds its texture better and isn’t as watery as frozen, but if using frozen, thaw and drain excess liquid before incorporating.

Is this recipe gluten-free?

The traditional recipe uses all-purpose flour; however, it can be adapted with a gluten-free flour blend without sacrificing taste.

Can I make this coffee cake dairy-free?

Yes! Substitute butter with vegan margarine or coconut oil, and use plant-based yogurt or sour cream alternatives for moisture.

How long will the cake stay fresh?

Stored properly, the Rhubarb Streusel Coffee Cake stays fresh for about 4-5 days refrigerated and up to two days at room temperature.

Can I double the recipe for a larger crowd?

Absolutely! This recipe scales well – just use a larger baking pan and monitor baking time closely to avoid overbaking.
