Simple Ingredients for Cranberry Oatmeal Muffin Bars

We use common ingredients that you could easily have on hand. The main ingredients are rolled oats, eggs, and some sort of liquid.

  • Rolled oats: We used rolled oats for this recipe, but you could easily use quick-cooking oats. Using the oats gives some texture versus only using flour
  • Flour: You could omit the flour, however, we like incorporating just a small amount because it helps provide the muffin-like texture
  • Eggs: Eggs play an important role in baking since they help provide structure, add moisture, and act as a glue
  • Sweetener: You can use regular sugar, honey, or maple syrup
  • Applesauce: Applesauce is a great fat replacer in many baked goods. The moisture also will keep most baked goods moist and fresh longer
  • Cranberries and orange juice: Adding fruit to your baked goods is a great way to add fiber and additional vitamins and nutrients
