Sour Cream Rhubarb Coffee Cake
A tangy-sweet treasure that brings families, friends, and rhubarb lovers together.
Introduction: A Slice of Comfort
Coffee cake has long been the unsung hero of brunch tables and late-night chats. But when tangy rhubarb joins the buttery, tender crumb of a sour cream coffee cake, something magical happens. This Sour Cream Rhubarb Coffee Cake is not just a dessert — it’s a nostalgic nod to farmhouse kitchens, Grandma’s baking days, and the seasonal rhythm of spring harvests.
Whether you’ve grown up picking rhubarb fresh from the garden or you’re just discovering it at the farmer’s market, this recipe offers a simple, soul-satisfying way to showcase one of nature’s boldest stalks.
The History of Rhubarb in Baking
Rhubarb has ancient roots, originally cultivated for medicinal purposes in China over 2,000 years ago. It wasn’t until the 18th century that rhubarb found its way into European pies and jams. In America, it thrived in northern climates, often paired with sugar to tame its tartness. Its striking pink color and puckery punch made it a favorite in springtime desserts — from crisps to crumbles, and of course, coffee cake.
The marriage of rhubarb and sour cream coffee cake likely evolved from Midwestern kitchens, where baking with what you had on hand — whether it was buttermilk, sour cream, or seasonal rhubarb — was a way of life.
Ingredients
For the Cake:
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 cup sour cream (full fat preferred)
- 2 cups fresh rhubarb, diced (or frozen, thawed and drained)
For the Cinnamon Streusel Topping:
- 1/2 cup brown sugar, packed
- 1/2 cup chopped walnuts or pecans (optional)
- 1 teaspoon cinnamon
- 2 tablespoons butter, melted
Instructions
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line it with parchment paper.
Step 2: Make the Streusel Topping
In a small bowl, mix together the brown sugar, cinnamon, nuts (if using), and melted butter. Set aside — this will be layered and sprinkled on top for that golden crunch.
Step 3: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
Step 4: Cream the Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar until light and fluffy (about 3 minutes). Add the eggs one at a time, beating well after each addition.
Step 5: Add Sour Cream and Dry Ingredients
Mix in the sour cream. Then gradually add the dry ingredients, mixing just until combined. Do not overmix — you want a tender crumb.
Step 6: Fold in the Rhubarb
Gently fold in the rhubarb pieces.
Step 7: Layer and Top
Spread half of the batter into the prepared pan. Sprinkle with half of the streusel topping. Add the remaining batter and smooth the top, then sprinkle with the rest of the streusel.
Step 8: Bake
Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean. Let cool slightly before serving.
Serving Suggestions
- Perfect with morning coffee or afternoon tea
