Let’s talk about snacks today! When it comes to snacks, I always feel challenged. So may (convenient) snack foods are super-duper processed. I end up not even buying them because if we have any in the house, that’s all my kids will eat. They buzz right past the usual snack choices and go for the garbage. Not a fan.

If you’ve visited my blog before you know that I’m a huge fan of not only whole food, but quick and easy cooking (or in this case, non-cooking). Take these 4 ingredient peanut butter oat bars for example. They are quite possibly the perfect snack!

Annnnnd, I saved the best thing for last! These bars are absolutely perfect for shape cutouts! Looking for a cute homemade treat/snack for any holiday? Instead of slicing them with a knife, grab your favorite cookie cutters and firmly press them all the way through (while the bars are still on the foil to make clean up super simple) and wah-lah, theme treats!
