- 1/4 teaspoon salt, to enhance flavors.

- 2 large eggs, for moisture and binding.

- 1 cup sour cream, ensuring the cake is moist and tender.
- 2 cups fresh rhubarb, for a tangy and vibrant burst of flavor.
- 1/2 cup all-purpose flour (for crumb topping), to help create the crumb texture.
- 1/2 cup old-fashioned rolled oats, adding a hearty crunch to the topping.

How to Make
Prepare Your Baking Dish
Begin by preheating your oven to 350°F (175°C). Select a 9×9-inch baking dish, then grease and flour it or line it with parchment paper. This step is crucial for ensuring that your sour cream rhubarb coffee cake releases easily after baking and maintains its beautiful shape.
Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This dry mixture will serve as the backbone of your cake, providing the necessary structure and ensuring an even distribution of leavening agents. Set this bowl aside while you prepare the wet ingredients.
Cream the Butter and Sugar
In a large mixing bowl, cream the softened unsalted butter and granulated sugar together until the mixture is light and fluffy. This process incorporates air into the butter, which will help your cake rise beautifully. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract, allowing its warm scent to fill your kitchen and set the stage for the delightful flavors to come.
Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the butter mixture, alternating with the sour cream. Start and finish with the dry ingredients to help maintain the cake’s structure. Mix until just combined; overmixing can make the cake dense, which we want to avoid. Finally, gently fold the chopped rhubarb into the batter, ensuring even distribution without breaking down the delicate fruit.
Prepare the Crumb Topping
To create the crumb topping, combine the remaining all-purpose flour, rolled oats, brown sugar, and ground cinnamon in a small bowl. Cut in the cold, cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This crumb topping will add a delightful crunch and flavor contrast to the soft cake beneath.
Bake to Perfection
Pour the batter into your prepared baking dish and spread it out evenly. Sprinkle the crumb topping generously over the cake batter. Bake in your preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean and the top is a beautiful golden brown. Allow the cake to cool slightly in the pan before slicing. Serve warm or at room temperature to fully enjoy the rich flavors and textures.
Tips for Success
- Ensure your butter is softened to room temperature for easier creaming with sugar.
- Do not overmix the batter; mix until just combined for a light and tender cake.
- For even more flavor, consider adding a teaspoon of lemon zest to the batter.
- Using fresh rhubarb is key for the best flavor; if using frozen, make sure to thaw and drain excess moisture.
- Allow the cake to cool slightly before slicing to help maintain its structure.
Variations to Try
- Add a handful of chopped walnuts or pecans to the crumb topping for an extra crunch and nutty flavor.
- Incorporate spices like cardamom or nutmeg into the batter for a unique twist.
- Substitute half of the sour cream for Greek yogurt for a slightly different flavor profile and texture.
- Mix in some shredded coconut for a tropical flair.
- Top the cake with a simple glaze made from powdered sugar and milk for added sweetness.
Common Mistakes to Avoid
- Overmixing the batter can lead to a tough cake; mix just until combined.
- Using cold butter instead of softened butter can affect the texture; always ensure butter is at room temperature.
- Not measuring flour correctly can lead to a dry cake; spoon the flour into the measuring cup and level it off.
- Skipping the crumb topping will alter the cake’s texture; it adds an essential crunch.
- Baking at an incorrect temperature can cause uneven baking; always preheat your oven.
Storage & Meal Prep
- Store leftover sour cream rhubarb coffee cake in an airtight container at room temperature for up to three days.
- Refrigerate the cake for extended freshness; it will keep for about a week in the fridge.
- This cake freezes well; wrap slices tightly in plastic wrap and place them in a freezer bag for up to three months.
- To serve from frozen, simply thaw the slices in the refrigerator overnight and enjoy at room temperature or warmed up.
- For meal prep, consider baking a double batch to enjoy throughout the week.
