Strawberry-Rhubarb Rouleau with Lemon Buttercream

I had a hard time choosing my cake this month. I felt like I should bake the Apple Cake as our apple tree was full of fruit waiting to be used, but nothing speaks to me quite like a rhubarb dessert. Then I went to the grocery story. Strawberries were on sale, and right next to them was a huge stack of rhubarb. Rhubarb is hard to find where I live. Rarely does anyone have it at the farmer's market, and there's only one store I've ever successfully bought it at, and that's always been in June. So to find such an abundance in early August - it was a sign.

This recipe provides instructions for either a layer cake or a roll (think Yule log or pumpkin roll). I opted to make the layer cake. The recipe as written produces an extra layer which I didn't want, so I halved the ingredients. The Genoese layer gets cut in half, filled with a strawberry-rhubarb compote and frosted with lemon buttercream. In general, I found the recipe easy to follow, though both the compote and buttercream produced substantially more than was needed for this cake. I had over almost 2 pints of the compote left over which we've been eating with pancakes.

The cake itself moist and tasty. The compote was amazing. The buttercream was very lemony but a little too sweet, I think because the added lemon juice required more powdered sugar than  would normally use. I needed to include more of the compote between the layers. I struggled to add more without it squeezing out. This would have been easier to do if I have piped a line of frosting around the edge to keep it in. Instead, we added an extra spoonful on the top.

Strawberry-Rhubarb Rouleau with Lemon Buttercream


  1. This cake caught my eye too but my rhubarb didn't flourish this year as it has in the past and I didn't have any for preserving in my freezer.

  2. Yum! Rhubarb speaks to my soul too. I can't wait until rhubarb season to try this!

  3. It was a sign that the strawberries and rhubarb were next to each other! I would have loved to try this one but rhubarb was nowhere to be found.

  4. Looks delicious! Good idea of halve the recipe - we always have too much just for two.
