• 1 cup granulated sugar

Step-by-Step Instructions

Preparing the Ingredients

1. Start by preheating your oven to 350°F (175°C). Grease and flour a baking pan, ideally a 9x13 inch for this recipe.
2. Measure out 2 cups of all-purpose flour, 1 ½ teaspoons of baking powder, ½ teaspoon of baking soda, and ¼ teaspoon of salt. Whisk them together in a mixing bowl to combine.
3. Chop 2 cups of fresh rhubarb into small pieces, ensuring they are all roughly the same size for even baking.

Mixing the Batter

1. In another mixing bowl, cream together ½ cup of softened unsalted butter and 1 cup of granulated sugar until the mixture is light and fluffy. This should take about 3 minutes.
2. Add in 2 large eggs, one at a time, mixing well after each addition. Then stir in 1 teaspoon of vanilla extract and 1 cup of sour cream until everything is well combined.
3. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few lumps are okay!
4. Gently fold in the chopped rhubarb with a spatula, ensuring it's evenly distributed throughout the batter.

Pouring into the Pan

1. Carefully pour the batter into the prepared baking pan, using a spatula to spread it evenly.
2. Tap the pan gently on the counter to remove any air bubbles that may have formed.

Preparing the Crumb Topping

1. In a separate bowl, combine ½ cup of all-purpose flour, ½ cup of old-fashioned rolled oats, ⅓ cup of packed brown sugar, and ½ teaspoon of ground cinnamon.
2. Add ¼ cup of cold, cubed unsalted butter to the dry mixture. Using a pastry cutter or your fingers, work the butter into the dry ingredients until the mixture resembles coarse crumbs.
3. Sprinkle the crumb topping evenly over the batter in the baking pan.

Baking the Cake

1. Bake the cake in the preheated oven for 40 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs.
2. If you notice the crumb topping browning too quickly, cover the cake loosely with aluminum foil for the last 10 minutes of baking.

Cooling the Cake

1. Once baked, remove the cake from the oven and allow it to cool in the pan for about 15 minutes.
2. After cooling, gently run a knife around the edges to loosen it, then turn it out onto a wire rack to cool completely.
3. Finally, slice and serve the cake warm or at room temperature, perhaps with a dusting of powdered sugar for an extra touch!

Variations

• Try adding a cup of chopped strawberries or blueberries for a fruity twist.
• Substitute half of the all-purpose flour with almond flour for a gluten-free option.
• For a spiced version, add ¼ teaspoon of nutmeg to the crumb topping.
• Top the cake with a cream cheese frosting for an indulgent dessert.
• Use canned rhubarb if fresh isn't available, just be sure to drain it well.

Serving and Storage Tips

Serving

Serve your Sour Cream Rhubarb Coffee Cake warm, perhaps with a dusting of powdered sugar or a dollop of whipped cream. This cake pairs wonderfully with a hot cup of coffee or tea, making it perfect for breakfast or as an afternoon snack.

Storage

Store any leftovers in an airtight container at room temperature for up to 3 days. For longer storage, wrap it tightly and freeze for up to 2 months. Thaw at room temperature, and reheat in the oven for a few minutes for that fresh-baked taste.

Common Mistakes

• Not greasing the pan properly can lead to sticking. Always grease and flour your pan well.
• Overmixing the batter may result in a dense cake. Mix until just combined for a light texture.
• Using cold ingredients can affect the rise. Ensure butter and eggs are at room temperature.
• Skipping the cooling time can lead to a crumbly texture. Allow the cake to cool before slicing for clean pieces.

Helpful Notes

• For a richer flavor, try using Greek yogurt instead of sour cream.
• Nut allergies? Substitute the oats with crushed graham crackers for the crumb topping.
• Add ½ cup of chopped nuts like walnuts or pecans to the batter for extra texture.
• For a dairy-free option, use plant-based butter and yogurt alternatives.
