strawberry rhubarb bars crumbly Your Way
Feel free to get creative and make these delightful bars uniquely yours with a few simple twists!
- Whole Wheat: Swap all-purpose flour for whole wheat flour for a nuttier flavor and added fiber. This change not only brings a wholesome touch but also enhances the texture, making it even more satisfying.
