These oatmeal cookie bars are everything you want from a classic oatmeal cookie, just baked all at once and sliced into bars. They’re soft and chewy through the middle, lightly crisp around the edges, and packed with oats, pecans, and dried cranberries for texture and balance. The brown sugar gives them that familiar caramel-like sweetness, while the oat flour keeps them hearty without feeling heavy.

Substitutions & Variations
This recipe is pretty flexible, so if you want to tweak it based on what’s already in your pantry, these swaps work well:
- Nuts: Pecans can be swapped for walnuts, almonds, or even pumpkin seeds if you want to keep things nut-free. Just keep the chop fairly small so the bars hold together nicely.
- Dried fruit: Cranberries are great here, but dried cherries, blueberries, or finely chopped apricots work just as well. If your dried fruit is on the larger side, a quick chop helps with even slices.
- Spice blend: A pumpkin or apple pie spice keeps things easy, but plain cinnamon works on its own. You can also mix cinnamon with a pinch of ginger or nutmeg if that’s what you have.
- Chocolate: Chocolate chips can replace part of the dried fruit if you want something a little more dessert-leaning. Dark or semi-sweet both work.
- Oil: Any neutral oil is fine here. I’d avoid coconut oil if you want the oats and spice to stay front and center, as it can overpower the flavor once cooled.
- Mix-ins: As a general rule, keep total add-ins around the same volume so the bars don’t crumble or turn dry.
Storage
Once cooled, store the bars in an airtight container at room temperature for up to three days. They can also be frozen for up to one month. Bring to room temperature before serving for the best texture.
Expert Tips
Oat flour tends to hide small clumps, so make sure it’s fully mixed into the wet ingredients before folding in the oats and add-ins. Smoothing the base first helps the bars bake evenly and keeps the texture soft instead of patchy.
FAQ
Rolled oats are the safest option for these bars. They give you that chewy, cookie-like texture without drying things out. Quick oats will still work, but the bars will be softer and less textured. I’d skip instant oats altogether – they’re too fine and can make the bars crumbly.
Yes, and this recipe handles swaps well. Chocolate chips, chopped nuts, seeds, or different dried fruit all work – just keep the total amount of add-ins roughly the same so the bars still hold together cleanly.
No chilling needed. The dough is thick enough to bake straight away, which is part of what makes these good for quick baking or meal prep.
Look for lightly golden edges and a center that looks set but still soft. They’ll firm up as they cool, so pulling them out a touch earlier keeps them chewy rather than dry.
This usually comes down to baking a little too long or overmixing once the flour goes in. Stir just until everything comes together and keep an eye on them toward the end of baking.
Serving Suggestions and More Recipes
These bars are great as-is, especially with coffee or tea, but they also hold up well if you want to slice them smaller and add them to a mixed spread. They’re sturdy without being dry, which makes them easy to pack or serve ahead without worrying about crumbling.

Oatmeal Cookie Bars
Ingredients
- 10 tablespoons neutral oil such as canola, sunflower, or vegetable (150 g)
- 1¼ cups light brown sugar 255 g
- ½ cup unsweetened applesauce 120 g
- 1 teaspoon vanilla extract 5 g
- 1 teaspoon pumpkin pie or apple pie spice blend 2 g
- ½ teaspoon fine sea salt 3 g
- 2 cups oat flour 240 g
- 1 teaspoon baking soda 5 g
- 1½ cups chopped pecans 180 g
- 2½ cups rolled oats 225 g
- ¾ cup dried cranberries 115 g
Instructions
- Preheat oven to 350°F/175C. Line a 9” x 13”/ 23cm x 33cm baking pan with parchment (or grease well).
- In a large bowl, combine oil, sugar, and applesauce. Whisk or beat with a hand mixer until fully emulsified (no obvious oil floating at the edges).
- Whisk in the vanilla, spice blend, and salt.
- Add the oat flour and baking soda. Stir until completely smooth (oat flour likes to form hidden clumps).
- Fold in the oats, cranberries, and chopped pecans.
- Scoop into prepared pan and spread in an even layer. As the mixture is very thick, this is easier to do if placed in dollops.
- Bake for 23-25 minutes until golden brown and puffy and firm on the edges and does move much in the center if tilted. Remove from oven and allow to cool for at least 30 minutes before cutting into 24 pieces.
- For best results wait until completely cool to cut. For very clean lines, freeze before cutting and use a serrated knife to cut. Bring to room temperature before eating.
- Store at room temperature in an airtight container for up to 3 days or in the freezer for 1 month. Bring to room temperature before eating.
