Summer Crumb Cake with Rhubarb + Strawberries – Gluten Free

Nothing really speaks summer better than fresh rhubarb and fresh strawberries. I love going ot the farmers market and smelling the scents of summer. Fresh fruit is everywhere: berries, stone fruit, citrus, it’s at almost every stall and one piece of fruit tastes better than the next.

Wanting to create something that screamed summer, it was a crumb cake recipe from Canelle et Vanille that inspired this recent dessert. With lots of strawberries on hand, not only did I make a whole tart for our Father’s day, family dinner but I made individual cakes (in Weck jars) for end of the year gifts.

When I stumbled upon the recipe, it inspired a memory from middle school. My first memory of a crumb cake was an aluminum, massive tray, manufactured, in the school cafeteria. I didn’t buy lunch or snack often, but on coffee cake day you can bet I had change in my pockets. The flavor of my first coffee cake is a far cry from this wonderfully light cake, but a crumb topping is a crumb topping – and that flavor is hard to beat

Combining fresh fruits with a classic crumb cake is a great flavor combo to finish off any weeknight summer barbecue. Top it off with some french vanilla ice cream and if you really want to be decadent, drizzle some warm, homemade caramel sauce over the top.

    The combination of rhubarb and strawberries is my all time favorite. Rhubarb used to grow like a weed in my backyard, when I was growing up.

    This crumb cake looks wonderful and I love the close-up shot of the rhubarb. 🙂

      As I start to replant my herb and veggie garden, you have inspired me to look into rhubarb. How happy would I be, next year, to have this wonderful root growing like a weed in my backyard! Have a wonderful week!

      Hi Rachel! Both the cake and the topping can be used in so many ways. I am going to do some crumb muffins and use this topping. Also, this topping can be frozen and used for lots of creations!

    Strawberries and rhubarb, nothing can sound more appealing to me…. this is one of my favorite combination of flavors! This cake looks really great!

    • Susan

      It’s only been in the last few years that I discovered rhubarb. It truly is one of those culinary mysteries that until you try it, it can easily fall off the radar. And you are so right, Kim, strawberries and rhubarb is a great combo!
