Step-by-Step Instructions

Preheat and Prepare:

Begin by preheating your oven to 350°F (175°C). Thoroughly spray a 9×9 inch baking pan with baking spray, then line it with parchment paper, leaving an overhang on two sides. This “sling” will make removing the entire block of bars for easy slicing a breeze.

Combine Dry Ingredients:

In a small to medium-sized bowl, whisk together the all-purpose flour, baking soda, cinnamon, and salt. Whisking ensures the leavening and spices are evenly distributed, preventing any bitter pockets in your finished bars.

Cream Butter and Sugar:

In the bowl of a stand mixer fitted with a paddle attachment, or using a large bowl and a hand mixer, beat the softened butter and packed light brown sugar together on medium-high speed. Your goal is a mixture that is light, fluffy, and pale in color, which should take about 2 to 3 minutes. This step is crucial for incorporating air into your batter.

Incorporate Eggs and Vanilla:

Add the eggs one at a time, beating well for a full minute after each addition to fully incorporate them. Scrape down the bottom and sides of the bowl with a spatula to ensure everything is mixed evenly. Then, beat in the 2 teaspoons of vanilla extract.

Fold in Dry Ingredients and Oats:

With the mixer on low speed, gradually add the flour mixture until it is almost combined. It’s okay if a few streaks of flour remain. Using a spatula, gently fold in the quick oats and raisins by hand. This prevents overmixing, which can lead to tough bars.

Press and Bake:

Transfer the thick dough to your prepared pan. Using your fingers or the bottom of a flat measuring cup, press the dough into a firm, even layer. Bake for 18 to 20 minutes. The bars are done when the edges are lightly golden and the center appears set. Avoid overbaking for the ultimate chewy texture.

Cool Completely:

Allow the bars to cool in the pan placed on a wire rack for at least 30 minutes. For best results, let them cool completely before frosting. This prevents the frosting from melting into the warm bars.

Prepare the Frosting:

While the bars cool, make the frosting. In a clean bowl, beat the softened butter and cream cheese together until smooth and creamy. Beat in the vanilla extract. Gradually add the sifted powdered sugar on low speed until incorporated, then beat on high for another minute until the frosting is light and fluffy.

Frost and Serve:

Once the bars are completely cool, spread the cream cheese frosting evenly over the top. Use the parchment paper sling to lift the entire block out of the pan onto a cutting board. Slice into squares, serve, and enjoy!

These bars are fantastic on their own with a glass of cold milk. For a next-level dessert experience, try serving a warm bar slightly à la mode with a scoop of vanilla bean ice cream. The contrast of the warm, spiced bar and the cold, creamy ice cream is sublime. They also pair wonderfully with a hot cup of coffee or tea for an afternoon pick-me-up.

Common Mistakes to Avoid

Storing Tips for the Recipe

FAQs

Can I use old-fashioned oats instead of quick oats?

Yes, you can. The texture will be chewier and the oat flakes will be more pronounced, but it will still be delicious.

My frosting is too runny. How can I fix it?

This usually happens if the butter or cream cheese was too soft or the bars were still warm. Place the frosted bars in the refrigerator for 20-30 minutes to allow the frosting to firm up. For next time, ensure your ingredients are softened but not melted, and that the bars are completely cool.

Can I make these bars without the frosting?

Absolutely! The bars are wonderfully flavorful and satisfying on their own. The frosting adds a decadent touch but is optional.

How do I know when the bars are done baking?

The edges will be lightly browned and will have started to pull away slightly from the sides of the pan. The center should look set and will spring back lightly when touched. A toothpick inserted into the center should come out with a few moist crumbs, not wet batter.

I’m not a fan of raisins. What can I use instead?
