Ingredients List

Here’s everything you need to make these scrumptious oatmeal raisin cookie bars. I promise, the ingredients are simple and straightforward, and you might even have most of them in your pantry already!

2 cups rolled oats (use old-fashioned for the best texture)
1 cup all-purpose flour (sifted for a lighter texture)
1/2 cup packed brown sugar (makes them wonderfully chewy)
1/2 cup granulated sugar (for that perfect sweetness)
1/2 cup unsalted butter, softened (let it sit out for a bit to get nice and creamy)
1/2 teaspoon baking soda (this will help them rise a bit)
1/2 teaspoon ground cinnamon (for that warm, cozy flavor)
1/4 teaspoon salt (to enhance all the flavors)
1 cup raisins (feel free to soak them in warm water for a few minutes to plump them up)
1 large egg (at room temperature for better mixing)
1 teaspoon vanilla extract (trust me, it makes all the difference!)

How to Prepare Oatmeal Raisin Cookie Bars Recipe

Alright, let’s get to the fun part—making these delicious oatmeal raisin cookie bars! I promise, the steps are super simple, and before you know it, you’ll have a warm, gooey treat ready to devour. Here’s how to do it:

First things first, preheat your oven to 350°F (175°C). This is crucial because you want your bars to bake evenly and come out perfectly golden.
In a mixing bowl, cream together that softened unsalted butter, packed brown sugar, and granulated sugar. I like to use a hand mixer for about 2-3 minutes until it’s light and fluffy. Wow, the smell of that butter and sugar combo is just heavenly!
Next, add in the large egg and vanilla extract. Mix until everything is well combined. Don’t worry if it looks a little bit lumpy—that’s perfectly normal!
Now, in another bowl, combine the rolled oats, sifted all-purpose flour, baking soda, ground cinnamon, and salt. Make sure to mix them up well so that the baking soda is evenly distributed.
Gradually mix the dry ingredients into the wet mixture. I usually do this in three parts, stirring gently after each addition. You want to avoid overmixing to keep those bars nice and chewy!
Time to fold in those delicious raisins! Just stir them in until they’re evenly spread throughout the batter. You can even use your hands if you want to get a little messy—it’s part of the fun!
Grab your greased baking pan (I like to use a 9×13 inch pan), and spread the mixture evenly into it. Don’t be shy about pressing it down a bit; you want it to hold together when it bakes.
Pop it in the oven and bake for 25-30 minutes. You’ll know it’s done when the edges are golden brown and the center is set. The aroma wafting through your kitchen will be absolutely irresistible!
Once baked, let the bars cool in the pan for about 10-15 minutes before cutting them into squares. Patience is key here—trust me, they’re worth the wait!

And there you have it! Perfectly chewy oatmeal raisin cookie bars that are ready to be enjoyed. I can hardly wait for you to try them!

Tips for Success with Oatmeal Raisin Cookie Bars Recipe

Getting these oatmeal raisin cookie bars just right is all about a few little details that can make a big difference. Here are my top tips to ensure your bars turn out perfect every single time:

Measure Ingredients Accurately: Use measuring cups and spoons for precision. If you’re using flour, spoon it into the cup and level it off with a knife—don’t scoop straight from the bag, or you might end up with too much!
Check for Doneness: Keep an eye on your bars as they bake. They’re done when the edges are golden brown and the center looks set. If you insert a toothpick, it should come out with just a few moist crumbs, not wet batter.
Let Them Cool: Resist the urge to dig in right away! Letting them cool in the pan for 10-15 minutes helps them firm up, making them easier to cut into neat squares.
Experiment with Mix-Ins: Feel free to add nuts, chocolate chips, or even coconut flakes for extra flavor and texture. Just keep the total mix-ins to about a cup to maintain the right consistency.
Use Room Temperature Ingredients: If your butter and egg are at room temperature, they’ll blend more easily, giving you a smoother batter and that yummy chewy texture.
Customize Your Spices: Don’t be afraid to play with spices! A pinch of nutmeg or a dash of vanilla bean paste can elevate the flavor to a whole new level.

With these tips in your back pocket, you’re all set to create the most delicious oatmeal raisin cookie bars that will impress friends and family alike. Enjoy baking!

Storage & Reheating Instructions

Once you’ve whipped up a batch of these delightful oatmeal raisin cookie bars, you’ll probably want to know how to keep them fresh for later. Storing them properly is key to maintaining that chewy goodness, so here’s what I recommend:

Room Temperature: If you plan on enjoying your bars within a few days, simply store them in an airtight container at room temperature. They’ll stay delicious for up to 5 days, but trust me, they might not last that long!
Refrigeration: For longer storage, pop them in the fridge. Just make sure they’re in an airtight container. This will keep them fresh for about a week, and they’ll still taste great, though they might lose a bit of that fresh-baked softness.
Freezing: Want to save some for a rainy day? These bars freeze like a charm! Wrap each bar tightly in plastic wrap, then place them in a freezer-safe bag or container. They’ll stay good for up to 2 months. When you’re ready to enjoy them, just thaw in the fridge overnight or let them sit at room temperature for about an hour.

Now, when it comes to reheating, you have a couple of options. If you prefer them warm (and who wouldn’t?), pop them in the microwave for about 10-15 seconds. This will bring back that fresh-baked feel. Just be careful not to overdo it, or they might get a bit too soft. Alternatively, you can warm them up in the oven at 350°F (175°C) for about 5-10 minutes. Either way, they’ll be just as delicious as the day you made them. Enjoy every last bite!
