Rhubarb Coffee Cake is topped with cookie-like streusel and every bite is studded with juicy rhubarb! An easy-to-make sheet cake that’s not too sweet and not too tangy, just delicious.
Rhubarb Coffee Cake is my favorite coffee cake when rhubarb is in season! It bakes high and fluffy with a delicious crunchy streusel and a juicy layer of fresh rhubarb. This rhubarb-and-streusel-topped sheet cake is not only easy to make from scratch in less than 20 minutes but it’s also a perfect dessert to make in advance. It tastes even better on the next day!
You will love the cookie-like topping! My go-to streusel is a traditional German streusel that is made with less sugar than an American crumb topping and is made without nuts. It bakes up into little cookie-like shortbread balls. So delicious!
I love simple cake recipes like this that come together quickly, are not too sweet, and are perfect for unexpected guests. This cake makes a great afternoon snack, brunch treat, or dessert. My favorite thing to make with rhubarb besides cake is my easy Strawberry Rhubarb Crisp. It’s definitely one of the easiest and best desserts you can make with rhubarb!

Tools used for making this Rhubarb Coffee Cake
9 x 13 inch Pan with Lid: I love this baking pan! It comes with a lid so it’s easy to transport baked goods or casseroles and it’s super easy to clean, everything slides right off. I use this pan for all my 9×13-inch cakes, bars, and casseroles.
Stand Mixer: The most beautiful appliance in my kitchen! I own it in the gorgeous Ice Blue but the new Imperial Black one is my current favorite color.
Vanilla Extract: This is my favorite vanilla extract. I also love their vanilla sugar for recipes where I don’t want to add more liquid.

Can you use frozen rhubarb?
Julia Foerster says
I haven’t tried that so I can’t say for sure. But I think the baking time would be longer if you use frozen rhubarb.

Loved your website. Thank you for sharing. You got a new fan.
I am a huge fan of this recipe. I’ve made it three times now (all with 1to1 gluten free flour from bob’s red mill) and it is so yummy! Making it again tomorrow for a party and thought it was tried and true enough I should leave a review. Thank you!
