Perfectly spiced, rich with butter, and topped with a smooth, creamy frosting, these bars are a crowd-pleasing treat for any occasion.
Ingredients
For the Cookie Bars:
- 1 cup unsalted butter, softened
- 1 cup brown sugar, packed
- ½ cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 teaspoon cinnamon
- 2 cups old-fashioned rolled oats
- 1 cup raisins
For the Buttery Frosting:
- ½ cup unsalted butter, softened
- 2 cups powdered sugar
- 2 tablespoons heavy cream (or milk, as needed)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
Instructions
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or grease lightly.
In a large bowl, beat the butter, brown sugar, and granulated sugar together until light and fluffy.
Mix in the eggs and vanilla extract, beating until smooth and fully combined.
In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.
Gradually mix the dry ingredients into the wet mixture until just combined.
Fold in the oats and raisins, ensuring they’re evenly distributed.
Spread the dough evenly into the prepared baking pan. Bake for 22-25 minutes, or until the edges turn golden brown.
While the bars cool, beat together butter, powdered sugar, vanilla, salt, and heavy cream until smooth and creamy.
Once completely cooled, spread the frosting over the bars. Slice into squares and enjoy!
Notes
✔ Use Room Temperature Butter – This ensures a light, fluffy texture in the batter.
✔ Don’t Overmix – Stir just until ingredients are combined to keep bars soft.
✔ Soak Raisins for Extra Softness – Let them soak in warm water for 10 minutes before adding to prevent dryness.
✔ Let Bars Cool Before Frosting – This prevents the frosting from melting into the bars.
