  • Brown Sugar, Granulated Sugar: Add sweetness and contribute to the chewy, caramel-like characteristics of the bars.
  • Eggs: Bind the ingredients together and add moisture to the cookie bars.
  • Vanilla Extract: Enhances the overall flavor with its warm, sweet aroma.
For the Dry Ingredients:
  • All-Purpose Flour: Forms the base structure of the cookie bars.
  • Baking Soda: Helps the bars rise and creates a light, tender crumb.
  • Cinnamon: Adds a warm, aromatic spice that complements the oats and raisins.
  • Salt: Balances the sweetness and enhances the overall flavor profile.
For the Mix-Ins:
  • Rolled Oats, Raisins: Provide texture, chewiness, and a classic oatmeal raisin cookie flavor.

Step 1: Warm Up The Oven

Crank your oven to a toasty 350°F (175°C) and grab a 9×13-inch baking pan. Generously coat the inside with cooking spray or butter to prevent sticking.

Step 2: Create A Creamy Base

In a spacious mixing bowl, whip together softened butter, brown sugar, and white sugar until the mixture becomes light, airy, and almost cloud-like.

Step 3: Blend Wet Ingredients

Pour in eggs and vanilla extract.

Mix thoroughly until everything combines into a smooth, silky texture.

Step 4: Prepare Dry Ingredients

In a separate bowl, whisk together these dry components:
  • All-purpose flour
  • Baking soda
  • Ground cinnamon
  • Salt

Ensure all ingredients are well integrated with no lumps.

Step 5: Combine Wet And Dry Mixtures

Slowly incorporate the dry ingredient mixture into the butter blend. Stir gently until just combined, being careful not to overmix.

Step 6: Add Delicious Extras

Fold in rolled oats and plump raisins, distributing them evenly throughout the dough.

Step 7: Spread The Goodness

Transfer the batter into the prepared pan, using a spatula to create an even layer that reaches all corners.

Step 8: Bake To Perfection

Slide the pan into the preheated oven and bake for 25-30 minutes. Watch for a beautiful golden-brown color signaling they’re ready.

Step 9: Cool And Slice

Allow the bars to cool completely in the pan. Once cooled, slice into delectable squares and serve with a smile.

Pro Tips for the Perfect Bake

  • Use softened butter at room temperature for extra creamy, tender bars that melt in your mouth.
  • Soak raisins in warm water for 10 minutes before adding to prevent them from drying out during baking.
  • Smooth the batter with a spatula to ensure uniform thickness and consistent golden-brown edges.
  • Reduce sugar by 2 tablespoons if you prefer less sweet treats or want to cut down on calories.
  • Keep bars in an airtight container at room temperature for up to 5 days, or freeze for longer preservation.
  • Chocolate Chip Oatmeal Bars: Replace raisins with semi-sweet chocolate chips for a classic sweet combination that kids and adults will love.
  • Nutty Oatmeal Bars: Mix in chopped walnuts or pecans for added crunch and rich, earthy flavor that complements the oats perfectly.
  • Coconut Oatmeal Bars: Sprinkle shredded coconut into the batter for a tropical touch and subtle sweetness that enhances the cookie's texture.
  • Maple Pecan Oatmeal Bars: Swap some granulated sugar with maple syrup and add toasted pecans for a warm, cozy flavor profile that screams comfort.
  • Pair with Warm Spiced Chai: Complement the cinnamon notes in the oatmeal raisin bars with a creamy, aromatic chai tea that echoes the cookie's warm spices.
  • Match with Vanilla Bean Ice Cream: Create a delightful contrast by serving a scoop of cold, smooth vanilla ice cream alongside the slightly crisp, chewy bars.
  • Serve with Caramel Macchiato: The rich, sweet caramel and espresso flavors will beautifully balance the wholesome, fruity profile of the oatmeal raisin bars.
  • Enjoy with Cold Milk: Highlight the classic cookie experience by pairing the bars with a cold glass of milk, which cuts through the sweetness and enhances the oatmeal's nutty undertones.

Storage Tips for Keeping Bars Fresh

Store bars in an airtight container with parchment paper between layers for up to 5 days in the refrigerator. Keep them cool and fresh by sealing tightly.

Wrap individual bars in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months for longer storage. Label with the date to track freshness.

Place bars in a sealed container at room temperature for 2-3 days. Keep away from direct sunlight and heat sources to maintain texture.

Warm refrigerated or frozen bars in the microwave for 10-15 seconds. Alternatively, reheat in a preheated oven at 300F for 5-7 minutes to restore soft, fresh-baked texture.
