I used Bobs Red Mill gluten free yellow cake mix and rolled oats. You can find Bobs Red Mill products at pretty much any grocery store. Especially whole foods and sprouts.
Homemade Nutri-Grain Bars
1 package bobs red mill gluten free vanilla cake mix
3/4 cup butter
2 1/2 cups Gluten Free Rolled Oats (I used Bobs Red Mill)
12 ounces Preserves or Jam
1 Tbs. Water
Preheat oven to 375° F.
Melt 3/4 cup butter. I just melted mine in the microwave.
Combine cake mix (just the powdered mix), and the oats in a large bowl; stir in the melted butter until the mixture is crumbly.
Add the egg and mix well.
Measure half of this mixture into a parchment lined 9 x 13 pan.
Combine preserves and water; spoon over crumb mixture in pan and spread evenly.
Cover with remaining crumb mixture.
Pat firmly to make top even. Sprinkle with 1/8 cup gf oats.
Bake for 25 minutes, until top is lightly browned.
Cool completely before cutting into bars.
As I said before, you can put them in individual ziplock bags for lunches or breakfast on the go.
