There’s something wonderfully nostalgic about biting into a soft, chewy oatmeal raisin cookie. Now imagine all that goodness packed into easy-to-make bars! These Oatmeal Raisin Cookie Bars are thick, hearty, and perfect for snacking, gifting, or pairing with your afternoon coffee. They bring the cozy flavors of cinnamon, brown sugar, and plump raisins into every bite.

What makes them even more irresistible? A light drizzle of vanilla glaze on top that adds just the right touch of sweetness. These bars are a fantastic alternative to classic cookies when you want something a little more shareable or when you’re short on time but craving homemade comfort.

What Kind of Oats Should I Use?

Old-fashioned rolled oats are the best choice here. They provide the chewy texture and hearty bite that gives these bars their signature character. Quick oats can work in a pinch, but avoid instant oats—they break down too much and make the bars mushy.

Ingredients for the Oatmeal Raisin Cookie Bars

Butter: Provides richness and helps the bars stay soft.
Brown Sugar: Adds moisture and a deep caramel flavor.
Egg: Binds everything together and gives the bars structure.
Vanilla Extract: Rounds out the flavor with a warm, fragrant note.
All-Purpose Flour: Forms the base of the dough.
Baking Soda: Ensures the bars rise just enough.
Salt: Balances the sweetness.
Cinnamon: Infuses the bars with cozy spice.
Old-Fashioned Oats: The heart of the recipe, giving that chewy, rustic texture.
Raisins: Provide bursts of sweetness and chew.
Powdered Sugar & Milk (for glaze): Create a simple drizzle that takes the bars over the top.

How To Make the Oatmeal Raisin Cookie Bars

Step 1: Cream the Wet Ingredients

In a large bowl, beat together the softened butter and brown sugar until light and fluffy. Add in the egg and vanilla extract, mixing well.

Step 2: Mix the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. Gradually add the dry mixture to the wet ingredients until just combined.

Step 3: Add Oats and Raisins

Stir in the rolled oats and raisins by hand, making sure they’re evenly distributed throughout the dough.

Step 4: Spread and Bake

Press the dough evenly into a greased or parchment-lined baking pan. Bake at 350°F (175°C) for 22–25 minutes or until golden brown and set. Let cool completely in the pan.

Step 5: Glaze and Slice

Mix powdered sugar with a splash of milk to make a drizzleable glaze. Drizzle over the cooled bars, then cut into squares.

How to Serve and Store These Cookie Bars

Serve these bars slightly warm or at room temperature for the best texture. They pair beautifully with coffee, tea, or a cold glass of milk. To store, keep them in an airtight container at room temperature for up to 4 days, or freeze for longer storage. When freezing, wrap individual bars to make them easy to grab on busy mornings.
