Ingredients Section

Here’s what you’ll need to create these delightful oatmeal raisin cookie bars:

1 cup (155 g) raisins – I prefer using plump, juicy raisins. If you’re adventurous, try mixing in some dried cherries or apricots!
1 cup warm water (105 to 115 degrees F) – This will help plump the raisins, enhancing their flavor.
1 cup (2 sticks / 227 g) unsalted butter, softened – Use high-quality butter for the best flavor. I recommend brands like Kerrygold or Challenge.
1 cup (200 g) light brown sugar, packed – For that hint of caramel flavor.
1/2 cup (100 g) granulated sugar – This will add sweetness without overpowering.
2 large eggs, room temperature – Make sure they’re at room temperature for a smoother batter.
1 teaspoon vanilla extract – Use pure vanilla for the best aroma and taste.
3 cups (270 g) old-fashioned oats – These give the bars their heartiness.
1 1/2 cups (188 g) all-purpose flour – For structure; feel free to substitute half with whole wheat for added nutrition.
1 1/2 teaspoons ground cinnamon – This adds warmth and depth to the bars.
1 teaspoon baking soda – For that perfect rise.
1/2 teaspoon kosher salt – Don’t skip this; salt enhances sweetness!
4 ounces (1/2 block / 113 g) cream cheese, room temperature – For the frosting. Softening makes it easy to incorporate.
1/4 cup (1/2 stick / 57 g) unsalted butter, room temperature – Also for frosting; be sure it’s soft!
1/2 teaspoon vanilla extract for frosting – Use pure for best flavor.
2 cups (250 g) confectioners’ sugar – This will give the frosting a smooth, sweet finish.

Prep Notes:

Ensure butter and cream cheese are at room temperature for a smooth batter and frosting.
If desired, feel free to use dairy-free substitutes or other sweeteners according to your dietary needs.

Step-by-Step Instructions

Let’s get baking! Follow these detailed instructions to ensure your oatmeal raisin cookie bars turn out perfectly every time:

Soak the Raisins: In a medium bowl, combine 1 cup raisins with 1 cup warm water. Let them soak for 30 minutes to plump them up.
Drain and Dry: After 30 minutes, drain the raisins well and pat them dry with paper towels. Set them aside for later.
Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper to prevent sticking.
Cream the Butter and Sugars: In a stand mixer, cream together 1 cup (227 g) unsalted butter, softened, 1 cup light brown sugar, packed, and 1/2 cup granulated sugar until the mixture is light and fluffy—about 2-3 minutes.
Add Eggs and Vanilla: Add 2 large eggs and 1 teaspoon vanilla extract, mixing until everything is well incorporated and smooth.
Mix Dry Ingredients: In a separate bowl, whisk together 3 cups old-fashioned oats, 1 1/2 cups all-purpose flour, 1 1/2 teaspoons ground cinnamon, 1 teaspoon baking soda, and 1/2 teaspoon kosher salt.
Combine Wet and Dry Ingredients: Gradually add the dry mixture to the wet mixture, mixing until just combined. Be careful not to over-mix!
Add the Raisins: Gently fold in the drained raisins with a spatula or wooden spoon.
Spread the Batter: Spread the batter evenly into the prepared pan, smoothing the top.
Bake: Bake in your preheated oven for 35 to 40 minutes until golden brown, and a toothpick inserted in the center comes out with a few moist crumbs.
Cool Completely: Allow the bars to cool completely in the pan before frosting—about 1 hour.
Make the Frosting: In a mixing bowl, beat together 4 ounces cream cheese, 1/4 cup unsalted butter, and 1/2 teaspoon vanilla extract until smooth.
Add Confectioner’s Sugar: Gradually add 2 cups confectioners’ sugar, mixing until creamy and fluffy.
Frost the Bars: Once the bars have cooled completely, spread the frosting evenly over the top. Slice into bars and serve!

Chef’s Tips:

For added texture, sprinkle some chopped nuts into the batter!
Ensure that you don’t over-bake to maintain that chewy texture.
If you’re in a hurry, you can skip the frosting for a quick snack!
