A soft and light old-fashioned Rhubarb Cake with a simple, sweet butter sauce poured over each slice!

Easy Rhubarb Cake with Butter Sauce

My husband has wanted to get in shape by way of mountain biking for a while. This winter he spent a lot of time researching bikes, and finally settled on an entry level one that he thought would be a good start for him.

The weather is finally nice enough that he is able to go riding so he asked a few guys to join him and they all set out to ride together. I was happy for him because he was excited about the adventure, but I was far more nervous that he was going to come back home in broken pieces! He’s not as athletic as he once was!

When he pulled into the garage and got out of the car in one piece I ran to hug him faster than if he’d been gone for a week! I was so relieved.

I was almost that excited when my Grandma made this Rhubarb Cake with Butter Sauce! It’s such a light, spongy cake. The sweet butter sauce compliments it so nicely, I think you will really like this recipe!
