Ingredients
Units
Scale
- 3 cups old-fashioned oats
- 1/4 cup whole wheat flour
- 1/4 cup brown sugar
- 1 Tbsp. cinnamon
- 2 tsp. baking powder
- pinch of salt
- 2 cups thinly sliced and chopped apple (about 2-3 medium apples)
- 1/4 cup melted butter
- 1/2 cup milk
- 1/4 cup honey
- 2 large eggs
- 1 Tbsp. vanilla extract
Instructions
- Pre-heat oven to 375 degrees F.
- Prepare 9×13 inch pan with cooking spray or parchment paper.
- Cut apples. Using a mandoline slicer, thinly slice apples. Then roughly chop the apples so you have very thin pieces that are about a 1/2-inch x 1/2-inch. (I usually cut apples in half and then use a mandoline slicer on the peel side first, carefully making my way to the apple core.
- In a large bowl, mix together oats, flour, brown sugar, cinnamon, baking powder, and salt. Stir in the cut apples.

- In a medium bowl, melt butter. Add in milk, honey, eggs, and vanilla and whisk together until combined. Stir wet ingredients into dry ingredients and mix until combined.

- Pour into the prepared baking dish and spread out in an even layer with the back of a spatula if needed. Bake for about 20-25 minutes or until cooked through and golden brown.
- Let cool before cutting into squares.
Notes
- You can also make these into mini bites by baking them in a mini muffin tin. You’ll want to cut down on the baking time by about 5 minutes and you’ll also have some extra batter; it’s the perfect size for an individual baking dish.
- Storage: Store these individual bars in an airtight container at room temperature for 1-2 days or in the refrigerator for 2-3 days. They don’t have any preservatives in them so they will mold at about day 4-5! Gently reheat the easy oatmeal bars in the microwave for 30 seconds.
- Freezer storage: These breakfast bars freeze well for 2-3 months in freezer-safe bags. Take them out to thaw on the counter or put them right into a lunchbox and they’ll be ready to eat by lunchtime.
- Ingredient notes: You can really use any apple here, but Honeycrisp, Pazazz, zestar, gala, or pink lady apples all work well.
- Special tools: A mandoline slicer will help get your apples thin and uniform, and I highly recommend using one!
- Serve with: Yogurt, fresh fruit, breakfast proteins, milk, eggs, etc.
