Ingredients You’ll Need

2 cups all-purpose flour: This forms the base of your cake. You can use whole wheat flour for a heartier texture.
2 tsp baking soda: This helps the cake rise, creating a nice fluffy texture.
1/2 cup salted butter, melted: Adds richness and flavor. If you’re in a pinch, you can use unsalted butter; just add a pinch of salt.
1 cup sugar: Regular granulated sugar sweetens the cake perfectly. You could use coconut sugar for a lighter flavor.
1 egg: This binds the ingredients together, resulting in a tender crumb.
1 tsp vanilla extract: Use pure vanilla extract for the best flavor.
1 cup whole milk Greek yogurt: This adds moisture and a tangy flavor. If you don’t have it, sour cream works just as well!
2 1/2 cups chopped fresh rhubarb: Fresh rhubarb brings the signature tartness that defines this cake. Frozen rhubarb can be a substitute—just thaw and drain excess moisture.
1/2 cup brown sugar: The brown sugar adds depth and a little chewiness to the topping.
1 tsp cinnamon: This fragrant spice complements the rhubarb beautifully.

How to Make Rhubarb Coffee Cake With Crumb Topping

Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures even baking! Prepare a 9×13 inch baking pan by lining it with parchment paper or greasing it generously with butter.
Prepare the Topping: In a small bowl, combine 1/2 cup brown sugar and 1 tsp cinnamon. Set this mixture aside as it will create that signature crumb topping.
Mix the Dry Ingredients: In a medium bowl, whisk together 2 cups all-purpose flour and 2 tsp baking soda. This helps to evenly distribute the leavening agent. Then set it aside.
Make the Wet Mixture: In a large mixing bowl, whisk the melted 1/2 cup salted butter with 1 cup sugar until smooth and well combined. Pour in 1 egg, 1 tsp vanilla extract, and 1 cup Greek yogurt, mixing until you obtain a creamy, uniform mixture.
Combine Wet and Dry Ingredients: Add the flour mixture to the wet ingredients. Stir with a spoon or spatula just until combined; it’s okay if a few lumps remain. The batter will be relatively thick.
Add the Rhubarb: Gently fold in 2 1/2 cups chopped fresh rhubarb until evenly distributed throughout the batter. Then, pour the batter into the prepared baking pan, spreading it to the corners for even baking.
Top with Cinnamon Sugar: Sprinkle the brown sugar and cinnamon mixture evenly over the top of the cake batter, creating that delightful crumb topping.
Bake the Cake: Place the pan in the oven and bake for 30-35 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan before cutting into it for the best results.

Storing & Reheating

To keep your Rhubarb Coffee Cake fresh, store it at room temperature in an airtight container for up to three days. If you want to keep it longer, refrigerate it for up to a week. For freezing, wrap individual pieces in plastic wrap, then place them in an airtight container or freezer bag, and this way, you can enjoy it for up to three months. When you’re ready to enjoy a slice, simply reheat it in the microwave for about 15-20 seconds or pop it in the oven at 350°F for a few minutes until warmed through. Note that the texture may be a bit different after freezing, but the flavor remains delicious!

Chef’s Helpful Tips

Avoid overmixing the batter; it can lead to a dense cake.
Room temperature eggs will incorporate better into your batter.
For an extra touch, try adding a handful of nuts like walnuts or pecans into the batter before baking.
Keep an eye on the baking time—it can vary based on your oven. Start checking a few minutes early!
If using frozen rhubarb, ensure to drain excess water to prevent the batter from becoming soggy.
Feel free to make this coffee cake ahead of time, as it tastes even better the next day after the flavors have melded.
