There's something magical about the aroma of cinnamon and oats wafting through the kitchen, bringing back memories of childhood baking sessions and cozy afternoons. These Oatmeal Raisin Cookie Bars take everything we love about the classic cookie and transform it into something even more special. Topped with a velvety maple-cinnamon frosting, they're chewy, warm-spiced perfection that somehow manages to be both nostalgic and excitingly new.

Last weekend, I brought these to a family gathering, and my grandmother, who's famously particular about her oatmeal raisin cookies, asked for the recipe. The secret? Taking time to properly cream the butter and sugar, and using fresh, plump raisins.

Essential Ingredients and Selection Tips

  • Butter: Use unsalted, room temperature butter for both bars and frosting. The temperature is crucial - it should indent easily when pressed but still hold its shape.
  • Raisins: Look for plump, moist raisins. If they feel dry, soak them in warm water for 10 minutes before adding to the dough.
  • Quick-cooking Oats: These provide the perfect texture. Old-fashioned oats work too but will give a chewier result.
  • Brown Sugar: Light brown sugar adds moisture and caramel notes. Make sure it's fresh and soft for the best results.
  • Maple Syrup: Use pure maple syrup for the frosting - the real stuff makes a noticeable difference in flavor.

Detailed Cooking Instructions

Pan Preparation:
Start with a properly prepared pan. Line your 9x9 inch pan with parchment paper, leaving overhang on two sides. Greasing the pan before adding parchment helps it stick in place while spreading the dough.
Creating the Perfect Dough:
Begin by creaming your room temperature butter and brown sugar until light and fluffy (about 3-4 minutes). Add eggs one at a time, fully incorporating each before adding the next. Combine dry ingredients separately and whisk thoroughly. Fold in oats and raisins gently by hand.
Baking Process:
Spread the dough evenly in the prepared pan using an offset spatula. Bake at 350°F for 25-30 minutes until edges are golden but the center is slightly underbaked. Cool completely before frosting.
Frosting and Finishing:
Whip room temperature butter until fluffy. Gradually add powdered sugar, then mix in maple syrup and cinnamon. Adjust consistency with cream as needed. Spread frosting over cooled bars and cut into squares with a plastic knife.

The key to this recipe lies in proper ingredient preparation and attention to texture. Through trial and error, I've found these techniques ensure consistently delicious results.

Chef's Essential Tips

  • Toast oats briefly for enhanced nutty flavor.
  • Use a plastic knife to cut the bars - it prevents the frosting from sticking.
  • If raisins are dry, soak them in warm water for 10 minutes and pat dry before use.

Ingredients

→ Cookie Bar Base

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

→ Maple-Cinnamon Frosting

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

Instructions

Step 01

Start by heating your oven to 350°F (175°C). Get your 9×9-inch baking pan ready by giving it a good coat of baking spray and lining it with parchment paper for easy removal.

Step 02

In a medium bowl, whisk together your flour, baking soda, cinnamon, and salt until well combined. This ensures all those warm spices are evenly distributed.

Step 03

Beat your room temperature butter and brown sugar together until it's light and fluffy - this usually takes about 2-3 minutes. Don't forget to scrape down the sides of the bowl as needed!

Step 04

Add your eggs one at a time, beating well after each addition, then stir in the vanilla. Gradually mix in your dry ingredients until just combined, then gently fold in those oats and raisins.

Step 05

Spread your dough evenly in the prepared pan and bake for 18-20 minutes, until the edges turn a lovely golden color. Let them cool in the pan for 5-10 minutes before moving to a wire rack.

Step 06

While the bars cool, beat your butter until smooth, then gradually mix in the powdered sugar. Add maple syrup, heavy cream, cinnamon, and maple extract if using. Beat until you've got a creamy, spreadable frosting.

Step 07

Once the bars are completely cool, spread that maple-cinnamon frosting over the top in an even layer. Slice into squares and enjoy!

Notes

  1. These cozy cookie bars combine the classic comfort of oatmeal raisin cookies with an indulgent maple-cinnamon frosting for an elevated treat.
  2. Try soaking your raisins in warm water for 5-10 minutes before adding them to the dough for extra plump, juicy raisins!
