Strawberry Rhubarb Crumble Cake

This cake is the perfect compliment to any summer meal (or as a meal by itself!) It is a great way to bring in summertime with fresh rhubarb and strawberry filling between tender white cake layers, a cinnamon oat crumble and a whipped vanilla bean buttercream. In classic Courtney style, it is delicious, tender, flavorful and so darn pretty!

We have had a long-standing friendship with Courtney, of Cake by Courtney. She has been our resident cake instructor for the past few years, and we love her passion for creating recipes that connect us beyond the food. Courtney bakes love and happiness into all her food. This recipe is capitalizes on all that Courtney offers.


Here are a few notes from Courtney when making this delectable cake:


If you want to make this cake, early summer is the time to do it. That’s when rhubarb is ripe and in stores. When you’re buying your rhubarb, look for the brightest red pieces you can find. Of course, with any of my fruit filled cakes, if you can’t find fresh seasonal fruit, you can always use frozen fruit. If you do use frozen fruit, let the fruit thaw a bit and pat with a paper towel to remove some of the excess moisture.


With this cake, because there is a soft filling, you want to take a couple extra steps when you stack and decorate.

  • Use chilled cake layers
  • Pipe a rim of frosting around each cake layer to act as a barrier to the filling
  • Don’t use too much filling in the cake – reserve the rest to serve on the side
  • Freeze the cake after it’s stacked, but before it’s crumb coated, to help stabilize the cake as you crumb coat
  • Freeze the cake again, after the crumb coat, to set the frosting and filling a bit more

Courtney used the Wilton 1M cake tip to create these delicate ruffles around the whole cake. They are so dainty, but pretty simple to accomplish! We love how it turned out.

We want to send a huge thanks to Courtney for sharing unique recipe with us. Everyday we get to gather with her is a treasure.

This post is part of our 2021 Grilling Gala (while the cake wasn’t grilled) it is the perfect companion for a summer time feast! And all the best meals we’ve ever shared definitely end with a slice of cake!

    Strawberries and rhubarbs are natural complements, and this crumble cake features the at their best. The texture of the cake with the sweetness of the fruit mixture is a winning combination.
