3 Ingredient Cinnamon Apple Oatmeal Bars Ingredients
For the Oatmeal Bars
• Sweetened Cinnamon Applesauce – Provides moisture and sweetness; for a twist, use unsweetened applesauce and add 2 teaspoons of cinnamon for extra flavor.
• Natural Peanut Butter or Almond Butter – Serves as a binding agent while adding healthy fats; substitute with sunflower seed butter for a nut-free option.
• Quick Oats – The main structural component that holds the bars together; opt for old-fashioned oats if pulsed into smaller pieces for better binding.
Step‑by‑Step Instructions for 3 Ingredient Cinnamon Apple Oatmeal Bars
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (177°C). As it warms up, line an 8×8-inch baking pan with parchment paper to prevent the bars from sticking. This step is essential for ensuring your 3 Ingredient Cinnamon Apple Oatmeal Bars bake evenly and lift out easily when they’re done.
Step 2: Mix Applesauce and Nut Butter
In a large mixing bowl, combine a jar of sweetened cinnamon applesauce with natural peanut butter or almond butter. Use a spatula or whisk to blend them together until the mixture is smooth and creamy, which should take about 3 to 5 minutes. This creamy base will provide both flavor and moisture to your bars.
Step 3: Incorporate the Oats
Once your applesauce and nut butter are well combined, add the quick oats to the bowl. Stir everything together until the oats are fully coated in the mixture and evenly distributed, which should take another 2 to 3 minutes. The consistency should be thick and sticky, ready to form your delicious bars.
Step 4: Transfer to Baking Pan
Pour the combined mixture into your prepared baking pan. Use a spatula to spread the mixture evenly, smoothing out the top for a consistent thickness. Make sure to press it down firmly—this will help the 3 Ingredient Cinnamon Apple Oatmeal Bars hold together during baking and when you cut them later.
Step 5: Bake Until Set
Place the baking pan in your preheated oven and bake for 15 to 20 minutes. You’ll know they’re ready when the surface appears dry and slightly golden, and the edges start to pull away from the pan. This is a great cue that your oatmeal bars are set and will have the perfect chewy texture upon cooling.
Step 6: Cool and Cut
After removing your bars from the oven, allow them to cool completely in the baking pan on a wire rack. Once cooled—this may take about 30 minutes—carefully lift the bars out using the parchment paper. Cut into squares or rectangles, and enjoy your wholesome 3 Ingredient Cinnamon Apple Oatmeal Bars!

Make Ahead Options
These 3 Ingredient Cinnamon Apple Oatmeal Bars are perfect for meal prep enthusiasts! You can mix the sweetened cinnamon applesauce and nut butter (or almond butter) up to 24 hours in advance, storing the mixture in an airtight container in the refrigerator to keep it fresh. Similarly, you can combine the wet ingredients with the quick oats, allowing the flavors to meld overnight. When you’re ready to bake, simply pour the prepped mixture into your baking pan and follow the original baking instructions, knowing that your bars will be just as delicious! This method saves valuable time on busy mornings while ensuring you enjoy these wholesome treats at their best.
