Homemade Oatmeal Bars That Beat the Box!

When I road tripped to California (DISNEY!!!) with my family a few years back, I grabbed a stash of snacks for the drive. One of them was Nature Valley’s® Peanut Butter Oatmeal Squares.

I’m usually a traditional granola bar girl, but I was instantly hooked on how soft these were and how strong the peanut butter flavor was. I also couldn’t help thinking I could make them even better at home. Or at least with better ingredients 🙂.

After a little testing, I finally got it right, and honestly, I’m way more excited than I probably should be about this recipe. These bars turned out so much better than anything from the store.

I’m truly obsessed. Like best breakfast bar I’ve ever had and I don’t say that lightly. They’re soft, chewy, and taste like a cross between a peanut butter cookies and oatmeal, but they’re made with minimal refined sugar, no flour, and plenty of peanut butter to keep them filling with a boost of protein.

Oatmeal Bars Recipe Ingredients

Ingredient GroupHelpful Tip
Peanut ButterUse creamy peanut butter for the smoothest texture and best binding. Avoid no-stir peanut butters since they can be inconsistent in baking.
SweetenersHoney adds chew and moisture while brown sugar boosts that classic soft baked flavor.
Oats and Oat FlourOld fashioned oats give structure while oat flour keeps the bars tender. Measure oat flour after blending up the whole oats.
Egg and VanillaThese help bind the bars and add richness. Make sure the egg is at room temp for easier mixing.
Peanut Butter ChipsThis Oatmeal Bars recipe is easy to switch up by using semi sweet, milk, or dark chocolate chips instead.
This oatmeal bar recipe ingredients mixed in a bowl and spread into a baking pan.

How To Make This Oatmeal Bars Recipe

  1. Prep pan: Heat oven to 325°F and line a pan with parchment, leaving an overhang.
  2. Mix batter: Beat until smooth, then gently fold in the chips.
  3. Bake: Spread evenly and bake until edges are lightly golden and the center is set.
  4. Cool: Let bars cool completely in the pan so they fully set.
  5. Slice: Lift out using the parchment and cut into bars.
The baked up treat still in the pan with a drizzle of melted peanut butter chips on top.

The BEST Baking Pan!

My Favorite Pan

I swear by this 8 x 8-inch pan when baking. It’s made from heavy aluminized steel, which means heat spreads quickly and consistently so you don’t get burnt edges or underbaked centers. The corrugated bottom helps with airflow and release, so bars lift out clean and bake with the perfect texture.

Storage

Let bars cool completely, then wrap each bar individually in plastic wrap. Store at room temperature for 2 to 3 days or in the fridge for up to 1 week.

Recipe Notes

Note 1: While these bars use naturally gluten-free ingredients, always check labels to be sure they were not processed in facilities that handle gluten. For guaranteed gluten-free bars, use certified gluten free products.
Note 2: To make oat flour, blend whole oats in a blender or food processor until they look like flour. Measure after blending, not before.
Storage: Let the bars cool fully, then wrap each one on its own in plastic wrap. Keep them at room temperature for 2 to 3 days or store in the fridge for up to 1 week.
