Tropical Rhubarb Cake

Ruhbarb for Tropical Ruhbarb Cake
It’s spring (and almost summer)! That means the rhubarb is growing in full throttle and its that time of year to make rhubarb desserts including this Tropical Rhubarb Cake! This cake is extremely moist, light, and decadent. It has a slight tart rhubarb taste with strawberry or raspberry jam swirled throughout and is topped with a whipped topping along with optional walnuts and toasted coconut. I hope you enjoy!

    Hey Sweet Pea
    Do you think I could substitute your ‘gelatin eggs’ or ‘chia/flax eggs’ for the eggs in the recipe?
    I just discovered your site today and am already a fan

      Hi Dave!!! I am glad you enjoy my site 🙂 You could try the gelatin substitute but it will not give you the rise that normal eggs do, which is why I would not recommend it. If you try it, let me know how it goes as I would love to know. Enjoy! 🙂
