  2. Rhubarb & Berry Crisp Recipe

Mother’s Day means something different to each of us. Maybe you celebrate your birth mother, grandmother, mentor or you yourself are now a mom. For me, Mother’s Day is a day to celebrate the amazing mother figures in our lives. I have numerous strong women in my life that I can thank for providing a mothering role. I’m so lucky to be friends with my mom and live so close to her – sometimes too close.

Mom has inspired and fed many of my passions and is a constant cheerleader for me. The earliest memories with her are in the kitchen, watching her and always wanting to help! I felt it was fitting for us to make this rhubarb crisp together in honor of her, my endless encourager!

This is delicious served warm or at room temperature. Personally, this is always my breakfast the next day as well, at least if there is any leftover.
