The smell of oats and cinnamon filling your kitchen has a way of bringing back those sweet childhood moments of baking with family on lazy afternoons. These Oatmeal Raisin Cookie Bars take the beloved classic cookie and turn it into something truly special. With their chewy texture and topped with creamy maple-cinnamon frosting, they blend familiar comfort with an exciting twist that'll make anyone's day better.

I shared these at our family get-together last weekend, and even my super picky grandma who never shares her oatmeal raisin cookie recipe asked me for mine! The trick? I spend extra time beating the butter and sugar together and always make sure to use juicy, fresh raisins.

Key Ingredients and Smart Shopping Advice

  • Butter: Grab unsalted butter and let it warm up to room temperature for both the bars and frosting. It should dent when you press it but not be melty or greasy.
  • Raisins: You want soft, juicy ones. If yours feel hard or dry, just soak them in some warm water for about 10 minutes before mixing them in.
  • Quick-cooking Oats: These give you just the right bite. Regular old-fashioned oats work too, but your bars will end up a bit chewier.
  • Brown Sugar: Go for light brown sugar to add moisture and that hint of caramel flavor. Make sure it's soft and clump-free.
  • Maple Syrup: Don't skimp here—get real maple syrup for the frosting. The fake stuff just won't give you that rich flavor.

Simple Step-by-Step Cooking Guide

Getting Your Pan Ready:
First things first, prep your 9x9 inch baking pan. Put down parchment paper with some hanging over two sides. A little grease under the paper helps it stay put while you spread out your dough.
Mixing Up Your Dough:
Start by beating your softened butter and brown sugar until it's fluffy and light, about 3-4 minutes. Add your eggs one at a time, mixing each one in completely. In another bowl, mix and whisk your dry stuff thoroughly. Then gently stir in your oats and raisins by hand.
Baking Your Bars:
Spread the mixture evenly in your pan with a spatula. Bake at 350°F for about 25-30 minutes. You'll know they're done when the edges turn golden but the middle still looks a tad underdone. Let them cool completely.
Making That Amazing Frosting:
Beat your room temp butter until it's light and fluffy. Slowly mix in powdered sugar, then add your maple syrup and cinnamon. Add a splash of cream if needed to get the right thickness. Spread it over your cooled bars and cut them with a plastic knife for clean slices.

Getting these bars just right comes down to how you handle your ingredients and paying attention to texture. I've made these countless times, and these little tricks have helped me nail it every single time.

Clever Baking Tricks

  • Give your oats a quick toast in the oven for extra nutty goodness.
  • Cut finished bars with a plastic knife to keep frosting from sticking everywhere.
  • Dry raisins? Just soak them in warm water for 10 minutes, pat them dry, and they're good to go.

Frequently Asked Questions

→ Is it okay to skip the frosting?
Totally! They're still tasty even without the maple-cinnamon frosting if you'd like a less sweet option.
→ What’s the best way to store these bars?
Keep them in an airtight container at room temperature for up to five days.
→ Can I substitute quick oats with regular oats?
You can! Old-fashioned oats will work, but they might create a slightly chunkier texture.
→ How do I tell if the bars are fully baked?
The edges should turn golden, and a toothpick poked in the middle should come out clean.
→ Is there a gluten-free version of these bars?
Yes, just replace the all-purpose flour with a 1:1 gluten-free flour blend.

Yield: 12 Servings (12 small bars)

Dietary: Vegetarian

Ingredients

→ Cookie Base

01 3/4 cup unsalted butter, softened to room temperature
02 1 cup raisins
03 2 large eggs, brought to room temperature
04 2 cups quick-cooking oats
05 3/4 cup packed light brown sugar
06 1 1/2 cups all-purpose flour
07 1 teaspoon baking soda
08 1/2 teaspoon fine salt
09 2 teaspoons vanilla extract
10 3/4 teaspoon ground cinnamon

→ Cinnamon-Maple Frosting

11 1/2 teaspoon ground cinnamon
12 1-2 tablespoons heavy cream, at room temperature
13 1/4 teaspoon maple extract (optional if you want more maple flavor)
14 1/2 cup unsalted butter, softened
15 1 tablespoon maple syrup
16 1 1/2 cups powdered sugar

Instructions

Step 01

Kick things off by cranking your oven to 350°F (175°C). Take a 9×9-inch pan, give it a good spray with cooking spray, then line it with parchment paper so removing the bars is a breeze.

Step 02

Combine your flour, salt, baking soda, and cinnamon in a medium mixing bowl. Whisk until everything’s evenly blended.

Step 03

Beat together the softened butter and brown sugar until it turns pale and fluffy. Remember to scrape down the sides of the bowl now and then!

Step 04

Stir in the eggs, one at a time, mixing well after each. Add the vanilla extract, then carefully mix in the dry ingredients until just combined. Don’t forget to fold in the oats and raisins at the end.

Step 05

Spread the dough evenly in the pan you prepped and bake it for 18–20 minutes. You’ll know it’s done when the edges are a golden brown. Let it cool in the pan for a bit—about 5–10 minutes—before transferring to a rack.

Step 06

With the bars cooling off, start on the frosting. Beat the butter until smooth, and then slowly mix in the powdered sugar. Stir in the maple syrup, cinnamon, cream, and maple extract if you’re using it. Mix until it’s creamy and easy to spread.

Step 07

Once those bars are nice and cool, evenly spread your maple-cinnamon frosting on top. Slice into squares and dig in!

Notes

  1. Soft oatmeal raisin bars topped with creamy maple-cinnamon frosting combine classic flavors with a fun twist.
  2. For plumper raisins, soak them in warm water for a few minutes before adding to the mix.
