Ingredients You’ll Need
These simple ingredients come together beautifully to create a cake that’s as flavorful as it is comforting. Each component plays an essential role—whether it’s providing moisture, that signature tang, or a perfect crunchy topping to finish it off.
- Butter flavor shortening: Adds richness and tenderness, keeping the cake moist without overpowering the rhubarb’s tang.

- Large egg: Binds everything together and contributes to the cake’s structure.
- Vanilla extract: Enhances the overall flavor with a sweet, aromatic touch.
- Baking soda: Ensures the cake rises nicely and becomes perfectly tender.
- Salt: Balances and intensifies the sweetness and other flavors.
- Flour: The foundation for the cake’s soft crumb.
- Chopped rhubarb: The star of the show, providing that delightful tartness and moist texture.
- Granulated sugar: Sweetens and mixes with cinnamon to create the flavorful streusel topping.

How to Make Rhubarb Streusel Coffee Cake Recipe
Step 1: Preheat Oven
Start off by heating your oven to 350°F (175°C). This is key to achieving an even bake and a perfect crumb, so your cake rises beautifully and bakes through without drying out.
Step 2: Prepare Cake Batter
In a large bowl, cream together the butter flavor shortening and brown sugar until it’s smooth and creamy—that velvety base sets the tone for the cake. Then, add the buttermilk, egg, and vanilla extract, mixing until everything is well combined. Next, gently stir in the flour, baking soda, and salt just until they come together (overmixing here can make the cake tough). Finally, fold in the chopped rhubarb carefully, ensuring it’s evenly distributed without breaking down too much. Pour this luscious batter into a greased 9×13 inch baking pan and smooth the surface.
Step 3: Make Streusel Topping
Whisk together granulated sugar and cinnamon in a small bowl to create that classic cinnamon-sugar base. If you’re feeling adventurous, mix in chopped pecans and shredded coconut—both add incredible texture and flavor. Sprinkle this streusel topping evenly over the cake batter, promising that signature crunchy, sweet crust after baking.
Step 4: Bake
Place the pan in your preheated oven and bake for 40 to 50 minutes. You’ll know it’s done when a toothpick inserted in the center comes out clean, and the streusel topping turns a beautiful golden brown. The cake will feel set to the touch and smell absolutely irresistible.
Step 5: Cool and Serve
Let the cake cool in the pan for at least 20 minutes to allow it to set fully and make slicing easier. Serve it warm or at room temperature. For an indulgent touch, add a dollop of whipped cream or a scoop of vanilla ice cream—the perfect cozy companion to your slice of this scrumptious Rhubarb Streusel Coffee Cake Recipe.

Make Ahead and Storage
Storing Leftovers
Wrap leftover cake tightly in plastic wrap or store it in an airtight container at room temperature for up to two days. For longer freshness, refrigerate it where it will keep well for up to five days while maintaining its moistness.
Freezing
You can freeze the cake either whole or in slices. Wrap the portions securely with plastic wrap and then in aluminum foil or place them in freezer bags. Stored this way, your Rhubarb Streusel Coffee Cake Recipe will keep delicious for up to three months. Thaw overnight in the fridge before reheating or serving.
Reheating
Warm individual slices in the microwave for about 20 seconds or reheat the whole cake in a 300°F (150°C) oven for 10-15 minutes. This revives the soft crumb and crisp topping beautifully, making it taste fresh and comforting again.
FAQs
Can I substitute fresh rhubarb with frozen rhubarb?
Yes, you can use frozen rhubarb, but be sure to thaw and drain it well to prevent excess moisture, which can affect the cake’s texture. Fresh rhubarb is ideal for the best flavor and consistency.
What can I use instead of shortening?
Butter is a great substitute for the butter flavor shortening and will add a lovely richness. Just keep in mind that you might get a slightly different texture and flavor profile—traditionally butter adds more depth.
Is it necessary to include pecans and coconut in the streusel?
Not at all! The pecans and coconut are optional but highly recommended for added crunch and flavor complexity. If you have nut allergies or prefer a simpler topping, just use the cinnamon-sugar mixture on its own.
How tart will this cake be?
The rhubarb lends a refreshing tartness that balances perfectly against the sweet cake and streusel. It’s not overpowering, but definitely noticeable enough to keep every bite lively and interesting.
Can this cake be made gluten-free?
To make this recipe gluten-free, substitute the all-purpose flour with a gluten-free flour blend that includes xanthan gum. The texture might vary slightly, but it should still bake up tasty and moist.
