Oatmeal Cookie Bars with Peaches and Crème Frosting {Plus a Duncan Hines Giveaway}

Cake mixes can be a great baking shortcut and sometimes a big life saver. It’s also a sentimental thing to me. My mother was a big believer in cake mixes. Just the smell of a freshly opened mix brings back many childhood memories.

If you’re a cake mix believer, too, then we are about to become very good friends. I was recently asked to join Duncan Hines’ Passionate Blogger program. Ten bloggers have been chosen to participate, and I am thrilled to be a part of the program and be among some great blogger company.

Duncan Hines Frosting Creations | Bake or BreakDuncan Hines has just introduced new spring flavors of their Frosting Creations. For any of you not familiar with Frosting Creations, you begin with a Frosting Starter and add in a flavor pack to make a quick and easy frosting. The spring flavors are Pink Lemonade, Key Lime, Peaches and Crème, and Fruit Punch.

Oatmeal Cookie Bars with Peaches and Creme Frosting | Bake or BreakTo help launch these great new flavors, I made these simple and delicious bars and topped them off with Peaches and Crème Frosting. The bars themselves start with a yellow cake mix and are packed with nuts and oats. Their not-too-sweet flavor is a great complement to the sweet peach frosting. It’s almost like eating peach cobbler in bar form.
