Ingredients
- Prep Time: 15 minutes
- Cook Time: 40-45 minutes
- Total Time: 55-60 minutes
- Servings: 12 servings
- 1 cup sour cream
- 1 teaspoon baking soda
- 1/2 cup unsalted butter, softened
- 1 1/2 cups granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1/2 teaspoon salt
- 2 cups diced fresh rhubarb
- 1/2 cup packed brown sugar
- 1 teaspoon ground cinnamon
- 1/4 cup chopped walnuts or pecans (optional)

Step-by-Step Instructions
To create the beloved Sour Cream Rhubarb Coffee Cake, follow these steps:
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish thoroughly to prevent sticking.
- Mix Sour Cream and Baking Soda: In a small bowl, blend the sour cream and baking soda. Allow it to sit for a few minutes, which helps to activate the baking soda for a lighter cake.
- Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. This will take about 3-5 minutes. Remember, the fluffier the mix, the better your cake will rise!
- Add Egg and Vanilla: Beat in the large egg and vanilla extract until well combined, making sure to scrape down the sides of the bowl for even mixing.
- Combine Dry Ingredients: In another bowl, whisk together the all-purpose flour and salt. This helps to distribute the salt evenly throughout the flour.
- Alternate Flour and Sour Cream: Gradually add the flour mixture to the butter mixture, alternating with the sour cream mixture. Start and end with the flour, mixing just until combined. Overmixing can lead to a dense cake.
- Fold in Rhubarb: Carefully fold in the diced fresh rhubarb gently into the batter, ensuring it’s evenly distributed without breaking it down too much. The vibrant color of the rhubarb adds a beautiful touch.
- Prepare Topping: In a small bowl, combine the packed brown sugar, ground cinnamon, and optional chopped nuts if you’re using them. This will create a crunchy topping to contrast with the moist cake.
- Spread the Batter: Pour the batter into the greased baking dish and spread it evenly across the bottom with a spatula. Don’t worry if it looks a bit thick; it will spread more as it bakes.
- Sprinkle Topping: Evenly sprinkle the brown sugar mixture over the top of the batter. This will caramelize slightly while baking, adding to the delicious flavor!
- Bake: Place the dish in the preheated oven and bake for 40-45 minutes. It’s ready when a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
- Cool and Serve: Allow the cake to cool in the pan for about 10-15 minutes before slicing. This cake is best enjoyed warm or at room temperature.
