Rhubarb Raspberry Streusel Cake

It may be little late in the season to post rhubarb recipes but I see there is still plenty around in markets and..... rhubarb, I love you so.

I love your unique flavor.

 Your ruby and emerald color and your texture, crunchy or soft.  

So sad your loveliness is shared for only a short time each year.  

But I guess it makes you all that more precious.

Ok enough with the tragic love sonnet to rhubarb. Just make this cake. You won't be sorry. 

I made two rhubarb cakes last weekend. Both are super easy to make and are each packed with flavor. Both recipes are German style so although they are delicious, the sugar content is lower than an American style dessert. I'll be posting the second one in a few days.

Ever since last year's Rhubarb Raspberry Gin Fizz, I've wanted to create something else with the flavor combo. Here it is.

For this rhubarb raspberry streusel cake, use a baking sheet with a high edge. Coat the pan with the cake layer, toss the raspberries and cut rhubarb together with vanilla and cornstarch, layer it on top of the cake batter. Top with homemade streusel. I peppered my streusel with dried raspberry bits for color and creativity but you don't have to.  Place the cake for 45 minutes in the oven and done.

This sheet cake feeds an army, or 24 people so it is perfect for your upcoming holiday barbecue. It also is a great make ahead cake because it keeps for several days in the refrigerator.

  1. Hello, i have just one question, I want to make this streusel but I cant find the dried raspberries here in Mexico Could you kindly tell me what else can I put in the mixture ?
    Thank you and I have made a few cakes from you and they are wonderful !!

    1. Hi! Thanks for reaching out. So happy you are enjoying the recipes. You can leave the dried raspberries out entirely and it won't effect the finished cake much. They are there mostly for color and small pop of flavor. Enjoy!
