Rhubarb Coffee Cake

One of my favorite recipes growing up... tastes even better gluten-free!

Rhubarb Coffee Cake

Moist, just the right amount of sweet & YUMMY!

This recipe from my Mom was one of my favorites growing up. Last year I finally made it Gluten-free, using GF Jules Flour  (affiliate link). Omg, SO GOOD! I haven’t had it in years and it is every bit as good as I remember… maybe even better.

Perfect texture, perfect amount of sweetness, juicy rhubarb and the best cinnamon-sugar-walnut crumble on top!

This is a must try during rhubarb season. Perfect for an occasion like Mother’s Day or Father’s Day or for an anytime treat!

Backstory on GF Jules Flour: When my son was diagnosed with Celiac Disease eight years ago, I read a book called “The First Year Celiac Disease” by Jules Shepard where Jules shared her recipe for flour. My mother and I used to make this Flour and it was life saving for us, allowing us to make all our usual recipes only gluten-free and they tasted the same, sometimes better! Then Jules started selling it. And 8 years later, it’s still my go to Gluten-free Flour. #CeliacDiseaseAwarenessMonth

  1. This recipe looks DIVINE! My grandfather used to grow rhubarb and I’d always have tons in my freezer for recipes — wish I’d had this one then! I can’t wait to make it (as soon as I get an oven again!).

    1. Thanks Jules! We have lots of rhubarb recipes because my Great-Grandfather used to grow tons of rhubarb and gave it all to my mom! This is my all time favorite and my mom and I actually think it’s better with GF flour, ha! You need to work on getting that oven! Let me know if you make it.
