Ingredients
This recipe has two parts that make it amazing. The oat blondies portion and then the cinnamon swirl. Yum!
They taste like the perfect combination of an oatmeal cookie and a blondie! And you know, in my book, that’s a combination that is pretty hard to beat!
For the oat blondies, you’ll need butter, brown sugar, sugar, eggs, vanilla extract, flour, quick-cooking oats, kosher salt, and baking soda.
You’ll note that for the oats in this recipe, I use quick-cooking oats. I have found them to give these blondies the perfect texture that I was looking for in this recipe!
For the cinnamon swirl, you’ll need brown sugar, heavy cream, cinnamon, butter, and vanilla extract.

Make the Blondie Batter
- Prep. Preheat the oven to 350º F. Coat a 9×13-inch baking dish with butter or spray well with non-stick baking spray. Set aside.
- Make the blondie batter. Beat butter until creamy with an electric mixer. Add brown sugar and granulated sugar and mix until light and fluffy, about 3 minutes. Add eggs and vanilla extract and mix until well combined. Stir in flour, oats, salt, and baking soda until well combined. Spread the batter evenly into the prepared 9×13 baking dish and set aside.
Make the Cinnamon Swirl
- Make the cinnamon syrup. Add brown sugar, heavy cream, and the ground cinnamon to a small saucepan set over medium-low heat. Stir together to combine with a wooden spoon. Add the butter and allow to melt completely and for the mixture to reach a rolling boil. Allow to cook until the sauce thickens, about 3 minutes. Remove from the heat and stir in the vanilla.
- Drop the syrup into the blondie batter. Drop the cinnamon sauce onto the top of the blondie batter by the tablespoon. Swirl into the batter with a skewer or butter knife.
Bake and Serve
- Bake until set in the middle and lightly golden brown, about 30 minutes. Cool completely before cutting and serving.

And when you smell them, you’ll understand just how hard that is! I have a feeling you might be hovering over them like I do, waiting for them to cool enough for just one!
