Make These Once – Everyone Will Ask for the Recipe!

I tasted these Puppy Chow Bars for the very first time at a Super Bowl Party! I was hooked! My husband took his first bite and said, “You have to blog these!”

When we found out who made these, the most frequent response our circle of friends gives in response was, “Of course Lisa made them!” Lisa really needs her own section on this blog. I guarantee you’ll flock to the stuff she makes! She found the recipe over at Butternut Bakery.

• Kid-Approved & Adult-Loved – These bars hit that nostalgic sweet spot – fun enough for kids, irresistible for grown-ups too!
