After gathering all the necessary ingredients and preparing them, it’s time to make this delicious Rhubarb Blueberry Sour Cream Coffee Cake.

Step 1: Making The Rhubarb Blueberry Filling

In a large bowl, mix 1 1/2 cups chopped rhubarb, 3/4 cup fresh or frozen blueberries, 1/4 cup brown sugar, and 1 tablespoon of lemon juice. Set aside.

Step 2: Making The Cake Batter

In another large bowl, cream together 1/2 cup butter and 1 cup granulated sugar until fluffy using an electric mixer. Add one egg at a time and mix thoroughly. After that, add 2 teaspoons vanilla extract.

In a separate medium bowl, mix together 3 cups flour, 1 teaspoon baking soda, and 3/4 teaspoons salt. Then add this to the butter mixture in four parts alternating with a cup of sour cream.

Step 3: Adding The Rhubarb-Blueberry Filling To The Cake Mix

Slowly fold the rhubarb-blueberry filling into the cake batter until it is mixed well.

Step 4: Creating The Streusel Topping

In a small bowl, mix together 1/3 cup brown sugar, 1 tablespoon cinnamon, and 8 ounces chopped walnuts with a fork for making streusel topping.

Step 5: Assembling And Baking The Coffee Cake

Preheat your oven to 350°F. Grease your bundt pan with butter or non-stick spray. Pour half of the batter into the prepared pan followed by half of the streusel topping mixture then add remaining batter on top of the streusel layer. Finally, sprinkle the remaining streusel over the top of the batter.

Bake in preheated oven for about 45 minutes or until a toothpick inserted in the center of the cake comes out clean.

Step 6: Let It Cool And Serve

Once the cake is ready, let it cool down completely before removing it from the pan. Serve and enjoy at any time of day.

Substitutions and Variations

One of the best things about baking is that there is always room for experimentation. So if you are feeling adventurous or want to make some substitutes, here are some ideas that you could try!

– Fruit substitutions: If Rhubarb and Blueberries are not your thing, you can swap them out with other fruits such as strawberries, raspberries, or even peaches. Fresh or frozen fruits can be used.

– Nutty crunch: If Walnuts aren’t your favourite nuts, Pecans or Almonds can be used as well to add some extra crunch and nutty flavour to the recipe. Alternatively, you can also omit the nuts altogether.

– Dairy-free: Want to make a dairy-free version? You can replace the sour cream in the recipe with an equal amount of non-dairy yogurt such as coconut yogurt or soy yogurt.

– Gluten-free: To make a gluten-free version, simply replace regular flour with gluten-free flour. The general rule is 1:1 ratio; but be sure to choose a gluten-free flour which has a similar texture to regular flour for best results.

These simple substitutions will allow you to create different variations of this coffee cake recipe, catering to different dietary needs and tastes. So do not hesitate to venture into different combinations until you discover your perfect coffee cake flavour!

Whether you’re new to baking or a seasoned pro, this recipe

Achieving the perfect Rhubarb Blueberry Sour Cream Coffee Cake can be quite a challenge, but with these tips, you can guarantee success. Here are some key tips for achieving optimal results every time:

1. Use Good Quality Ingredients: Make sure you use the freshest and highest quality ingredients available. Fresh rhubarb and blueberries will make all the difference in taste.

2. Follow the Recipe Measurements: Don’t deviate from the recipe measurements when it comes to ingredients such as flour, baking soda, and salt. These ingredients are crucial to the texture and structure of your cake.

3. Prepare Your Pans: Prepare your pans properly by greasing and flouring them so that your cake doesn’t stick. A bundt pan or a 9×13 inch baking pan is best for this recipe.

4. Mix Cake Ingredients Well: When mixing your cake ingredients, it’s important not to overmix the batter. Overmixing can cause your coffee cake to be dense and tough.

5. Streusel Topping: Don’t forget to prepare your streusel topping as it adds flavor and crunch to your coffee cake. It’s also essential in balancing out the sweetness of the rhubarb and blueberries.

6. Cool Before Icing: Once you’ve removed your cake from the oven, let it cool before icing it with sour cream glaze. Your frosting will melt and become runny if applied while the cake is still warm.

7. Keep an Eye on Baking Time: Bake the cake until it is golden brown on top and baked through in the center – this typically takes 50-60 minutes for a bundt pan or 35-40 minutes for a rectangular pan.

8. Have Fun Experimenting: While this recipe is certainly delicious as is, don’t hesitate to make it your own! Try different fruits like strawberries instead of blueberries, or add walnuts or cinnamon to the streusel topping. The possibilities are endless!

By following these tips, you will be well on your way to a perfectly baked Rhubarb Blueberry Sour Cream Coffee Cake every time. Enjoy!
