Rhubarb Coffee Cake

One of my favorite recipes growing up... adapted to be gluten-free

Moist, just the right amount of sweet, & YUMMY!

This recipe from my Mom was one of my favorites growing up and it’s the first time making it Gluten-free. Omg, SO GOOD! I haven’t had this 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!

  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.
