Creating these Easy California Prune Oatmeal Squares
I know what you are thinking…and the answer is no, they are not just your grandmother’s favorite food!
I recently visited a prune orchard and drying facility in California and fell even more in love with prunes and prunes benefits.
California Prunes have a place in everyone’s diet: toddlers, teens, adults and elderly. That’s why I adore these bars because I can make them for all audiences; my nephew, my friends or the grandparents in my life.

California Prune Nutrition and Facts:
Prunes benefits…
- Research says consuming 5-6 prunes a day may support healthy bones.
- Prunes support good gut health.
- Boosting antioxidant intake can help provide added protection against heart, eye, memory and immune systems.
- California Prunes taste and pair like no other prunes in the world. They are fresh and sweet, have a reliable consistency and have a rich, smooth mouthfeel.
- A serving of 4-5 prunes has 280 mg potassium and 23 mcg of vitamin K. Potassium helps muscles contract and vitamin K helps to improve calcium balance & promotes bone mineralization.

I’ve incorporated prunes into a handful of recipes on Kroll’s Korner including my Vegan Chocolate Chip Cookies , Ham & Cheese Puff Pastry , and Creamy Chocolate Smoothie !
