In addition to their complementary flavors and textures, oatmeal, apples and raisins are also nutritious ingredients. Oatmeal is a good source of fiber and protein, while raisins and apples are rich in antioxidants and fiber. By combining these three ingredients in baking, you can create a dessert that is both tasty and somewhat healthy.

Tips for making the Apple Oatmeal Bars with Raisins


I recommend prepping all of your ingredients before starting the recipe. This prep work always helps to make sure you have everything properly measured and close at hand.

  • Oatmeal: use old-fashioned oats. Instant oatmeal will absorb moisture from the wet ingredients resulting in a gummy cookie.
  • Unsalted butter: Eliminate the salt in the recipe if you use salted butter. Melt the butter and cool slightly before starting the recipe.
  • Vanilla: use a high-quality pure vanilla extract.
  • Gluten-Free flour: There are many commercially available brands for gluten-free flour. My favorites are Bob's Red Mill or King Arthurs all-purpose gluten-free flours.
  • Granulated sugar and light brown sugar
  • Ground cinnamon, baking soda and salt
  • One large egg
  • Raisins
  • One apple: I like Granny Smith apples for this recipe. Peel and core the apple. Then grate the apple finely using a cheese grater.
