Ingredients for Apple Cinnamon Oat Crumble Bars

• 1/3 cup pure maple syrup or honey
• 1 teaspoon ground cinnamon

That’s it! Four wholesome ingredients you likely already have in your kitchen.

Ingredient Notes

Rolled Oats: Old-fashioned rolled oats provide the best texture. Quick oats will create a softer bar.

Apples: Use firm varieties like Honeycrisp, Fuji, or Granny Smith for the best balance of sweetness and structure.

Maple Syrup or Honey: Either works beautifully. Maple syrup adds a deeper, caramel-like flavor.

Cinnamon: Fresh, fragrant cinnamon makes all the difference.

• Mixing bowl
• Spoon or spatula

Substitutions

• Swap apples for diced peaches for a summery twist
• Use agave syrup instead of maple or honey

Don’t be afraid to experiment—this recipe is forgiving and flexible.

How to Make Apple Cinnamon Oat Crumble Bars

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper for easy removal.

Step 2: Mix the Ingredients

In a large bowl, combine the rolled oats, diced apples, maple syrup (or honey), and cinnamon. Stir until everything is evenly coated.

The mixture will look rustic and slightly sticky—that’s exactly what you want.

Step 3: Press Into the Pan

Transfer the mixture into the prepared baking dish. Press it down firmly with the back of a spoon or your hands to help it hold together.

Step 4: Bake

Bake for 25–30 minutes, or until the top is lightly golden and the apples are tender.

Your kitchen will smell like apple pie heaven—anything but boring!!

Step 5: Cool and Slice

Allow the bars to cool completely before slicing. This step is important—they firm up as they cool.
