These Oatmeal Cookie Bars blend homey warmth with grab-and-go ease, turning classic oatmeal cookie flavors into an addictive handheld snack. The mix of soft oats, juicy raisins, melty chocolate chips, and toasty walnuts creates an amazing texture that'll have you reaching for seconds. I've spent countless afternoons tweaking this recipe for school fundraisers and family reunions until I nailed that perfect soft-yet-chewy consistency everyone raves about.

I first came up with these bars during a stormy day when my daughter wanted cookies but I was crunched for time. This pan version was such a success that now everyone expects us to bring them to every school function.

Key Components

  • Butter: Go with unsalted butter that's properly softened - it should dent when you push it but not be melty. This helps it mix properly with the sugars for that chewy goodness we want
  • Old-Fashioned Oats: Don't try using quick oats - only old-fashioned ones give you that substantial chew that makes these bars stand out. They also help lock in moisture so your treats stay fresh
  • Light Brown Sugar: The touch of molasses in brown sugar is key for achieving that perfect chew and caramel flavor. Always push it down firmly when you measure
  • Eggs: Go with large eggs at room temp for better mixing and structure. I just pop them in warm water for 10 minutes if I forget to take them out early
  • Vanilla Extract: Real vanilla adds wonderful richness. This is worth splurging on for the best flavor
  • Chocolate Chips: Semi-sweet works beautifully, though dark chocolate adds a grown-up twist if that's your thing
  • Raisins: Try to find plump, moist ones. A quick soak in warm water beforehand makes them extra tender in the bars
  • Walnuts: Taking a minute to toast them lightly in a dry pan really brings out their flavor

Step-by-Step Method

Preparation:
Put your oven rack right in the middle and heat to 350°F. Take some parchment paper and line your 9×13-inch pan, letting paper hang over the sides so you can lift the bars out later. Give any exposed parts of the pan a light coat of grease.
Mixing the Dough:
In your mixer bowl, beat the softened butter with both sugars for about 3-4 minutes until it looks fluffy and lighter in color. Drop in eggs one at a time, mixing for a full minute after each. Scrape everything down, then stir in the vanilla until it's all smooth.
Dry Ingredients:
Take another bowl and stir together your flour, salt, cinnamon, baking soda, and baking powder. Slowly add this mix to your wet stuff, keeping the mixer on low until everything's just combined.
Final Mix:
Use a spatula to fold in your oats, chocolate chips, drained pre-soaked raisins, and those toasted walnuts. You'll end up with pretty thick dough.
Baking:
Spread all that dough into your prepared pan, using slightly wet hands to press it down evenly. Bake for 25-30 minutes until the middle looks set but still a bit soft. Let them cool completely before cutting.

Finding out that soaking raisins beforehand made such a huge improvement was a game-changer for me. My kids always fight over who gets to push the dough into the pan - though I've learned to keep the chocolate chips far away during this process!

Why Bars Beat Cookies

These treats hit that sweet spot between crispy edges and tender middles. Unlike regular drop cookies, the bar shape lets moisture spread more evenly, so every bite has the same amazing texture. Using that parchment paper hanging over the sides makes getting them out and cutting them up super easy.

Frequently Asked Questions

You need 35 minutes—10 to prep and 25 to bake.
→ Can I swap old-fashioned oats with quick oats?
Yes, quick oats work fine but will change the texture slightly.
→ What’s the best way to store these bars?
Keep them in a sealed container in the fridge for 4-5 days, or freeze up to 3 months.
→ How can I tell if the bars are baked perfectly?

Ingredients

→ Wet Ingredients

01 2 large eggs
02 1 tablespoon vanilla extract
03 1/2 cup granulated sugar
04 1 cup light brown sugar
05 1 cup butter, softened

→ Dry Ingredients

06 1 teaspoon kosher salt
07 2 cups rolled oats (old-fashioned)
08 1 teaspoon baking soda

→ Mix-ins

12 1/2 cup walnuts
13 3/4 cups raisins
14 1/2 cup semi-sweet chocolate chips

Instructions

Step 01

Set your oven to 350°F. Grab a 9×13-inch pan, line it with parchment, and spray it lightly with nonstick spray. Put it aside.

Step 02

Use a stand mixer with a paddle attachment. Blend softened butter, brown sugar, and white sugar on medium for about 2 minutes. Toss in the eggs, vanilla, salt, cinnamon, baking soda, and baking powder. Keep mixing until it’s smooth, scraping the sides here and there.

Step 03

Switch the mixer to low speed and slowly add the flour and oats. Mix just enough to bring everything together.

Step 04

With a spatula, fold in the chocolate chips, raisins, and walnuts until they’re spread out evenly.

Step 05

Press the dough into the lined pan and bake for roughly 20-25 minutes. The edges should look golden and firm.

Step 06

Let the bars cool all the way before cutting them so they don’t fall apart.

Notes

  1. You can use quick oats instead of rolled oats for a slight texture change.
  2. The middle might seem underbaked but firms up as it cools.
  3. Keep refrigerated in an airtight container for 4-5 days.
  4. Freeze them separated by parchment for 2-3 months.
