Step-by-Step Instructions

Preparing the Ingredients

1. Preheat your oven to 350°F (175°C) and grease a baking dish with butter or non-stick spray.
2. Gather all your ingredients on the countertop for easy access.
3. Chop the fresh rhubarb into small pieces, about ½ inch thick, and set aside.

Mixing the Batter

1. In a large mixing bowl, combine 1 ½ cups of all-purpose flour, ¾ cup of sugar, ½ teaspoon of baking soda, ½ teaspoon of baking powder, ¼ teaspoon of salt, and ½ teaspoon of ground cinnamon.
2. Stir the dry ingredients together until well mixed, creating a fluffy, light base for your cake.
3. Add ½ cup of sour cream, ½ cup of vegetable oil, 1 large egg, and 1 teaspoon of vanilla extract to the bowl.
4. Mix the ingredients together until just combined; be careful not to overmix, as this can make the cake dense.

Adding the Rhubarb

1. Gently fold in the chopped rhubarb into the batter using a spatula. This will infuse the cake with that delightful tartness.
2. Ensure the rhubarb is evenly distributed throughout the batter for consistent flavor in every bite.

Preparing the Topping

1. In a separate bowl, mix ⅓ cup of packed brown sugar, ¼ cup of all-purpose flour, and ½ teaspoon of cinnamon.
2. Add 3 tablespoon of softened unsalted butter to the mixture and use your fingers or a fork to combine until you achieve a crumbly texture.

Baking the Cake

1. Pour the batter into the prepared baking dish, spreading it evenly with a spatula.
2. Sprinkle the crumbly topping generously over the batter, creating a sweet, crunchy layer.
3. Bake in the preheated oven for 45 minutes, or until a toothpick inserted into the center comes out clean.

Cooling and Serving

1. Once baked, remove the cake from the oven and let it cool in the baking dish for about 10 minutes.
2. Transfer the cake to a wire rack to cool completely before slicing.
3. Serve warm or at room temperature, and enjoy with a cup of coffee or tea for the perfect cozy afternoon treat!

Variations

• Try using strawberries or apples instead of rhubarb for a sweeter twist.
• Add chopped nuts, like walnuts or pecans, for extra crunch and flavor.
• For a seasonal touch, incorporate spices like nutmeg or pumpkin spice in the batter.
• Make it gluten-free by substituting all-purpose flour with a gluten-free blend.
• Top with a drizzle of icing or a dollop of whipped cream for added indulgence.

Serving and Storage Tips

Serving

Serve the One-Bowl Rhubarb Coffee Cake warm, dusted with powdered sugar or enjoyed plain. Pair it with a hot cup of coffee or tea for the ultimate cozy experience. It's also delightful with a scoop of vanilla ice cream or a dollop of whipped cream for a special treat.

Storage

Common Mistakes

• Overmixing the Batter: This can lead to a dense cake. Mix just until combined.
• Using Old Rhubarb: Fresh rhubarb is key for flavor. Ensure your rhubarb is crisp and vibrant.
• Skipping the Cooling Step: Cutting the cake too soon can make it fall apart. Allow it to cool completely.
• Not Measuring Ingredients Accurately: Use proper measuring cups for dry and wet ingredients to ensure consistency.

Helpful Notes

• For a dairy-free option, substitute sour cream with a plant-based yogurt.
• Add a handful of blueberries or raspberries for a mixed berry flavor.
• If you prefer a sweeter cake, increase the sugar to 1 cup.
• Consider adding a teaspoon of lemon zest for a fresh, zesty flavor.
