3 Ingredient Cinnamon Apple Oatmeal Bars Ingredients
For the Batter
• Sweetened Cinnamon Applesauce – Provides moisture and flavor; you can substitute with unsweetened applesauce and add 2 teaspoons of cinnamon for extra zing.
• Natural Peanut Butter or Almond Butter – Binds the ingredients together while adding healthy fat; choose natural nut butter without added oils, or use sunflower seed butter for a nut-free version.
• Quick Oats – Adds structure to the bars; for best results, use quick oats, but rolled oats can be pulsed in a food processor for a similar texture.

Step‑by‑Step Instructions for 3 Ingredient Cinnamon Apple Oatmeal Bars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (177°C). While the oven warms up, line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later. This simple step ensures easy cleanup and helps the 3 Ingredient Cinnamon Apple Oatmeal Bars lift out effortlessly after baking.
Step 2: Mix Applesauce and Nut Butter
In a large mixing bowl, combine the sweetened cinnamon applesauce and your choice of natural peanut or almond butter. Use a spatula or wooden spoon to mix them thoroughly until the mixture is creamy and well-combined. You’ll know it’s ready when no streaks of nut butter remain, and the blend has a smooth consistency.
Step 3: Incorporate the Oats
Gradually add the quick oats to the applesauce and nut butter mixture, stirring until fully incorporated. The oats should be evenly distributed, creating a cohesive batter that appears thick and chunky. If you wish to adjust the sweetness of your 3 Ingredient Cinnamon Apple Oatmeal Bars, you can mix in a drizzle of maple syrup or honey at this stage.
Step 4: Transfer to the Baking Pan
Pour the mixture into your prepared baking pan, using a spatula to spread it out evenly. Gently press down on the mixture to ensure it holds together well. This step is crucial for achieving the perfect texture in your bars, allowing them to bake uniformly and hold their shape after they cool.
Step 5: Bake Until Set
Place the baking pan in the preheated oven and bake for 15-20 minutes. Keep an eye on the surface; it should look dry and slightly golden when ready. You can check for doneness by gently pressing the center; it should feel firm to the touch. Once done, remove the pan from the oven and allow it to cool completely in the pan.
Step 6: Cool and Cut
Once the 3 Ingredient Cinnamon Apple Oatmeal Bars are cool, use the parchment paper overhang to lift them out of the pan. Place them on a cutting board and slice them into squares or rectangles, depending on your preference. Allowing them to cool fully is key, as cutting them too early can lead to crumbling.
Step 7: Store for Later Enjoyment
Transfer the cut bars to an airtight container. If you have any leftover, store them in the refrigerator for up to a week. For longer storage, consider freezing them individually wrapped to ensure you always have a healthy snack on hand. Enjoy your delightful and nutritious 3 Ingredient Cinnamon Apple Oatmeal Bars!
