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 Valleyโ€™sยฎ Peanut Butter Oatmeal Squares.

Iโ€™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 couldnโ€™t help thinking I could make them even better at home. Or at least with better ingredients ๐Ÿ™‚.

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

Iโ€™m truly obsessed. Like best breakfast bar Iโ€™ve ever had and I donโ€™t say that lightly. Theyโ€™re soft, chewy, and taste like a cross between a peanut butter cookies and oatmeal, but theyโ€™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.

How To Make This Oatmeal Bars Recipe

  1. Prep pan: Heat oven to 325ยฐF 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 thisย 8 x 8-inch panย when baking. Itโ€™s made from heavy aluminized steel, which means heat spreads quickly and consistently so you donโ€™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.

    Hiya
    Going to try your recipes looks so yummy.
    Was wondering if you think biscuit spread would work to an alternative to peanut butter. X

      Hi! Iโ€™m actually not familiar enough with biscuit spread to say for sure, so I canโ€™t confidently recommend it here.
