Ingredients
Crust:
- 1 box (15.25 ounces) yellow cake mix – I love using Duncan Hines, but any brand will do!
- 1/2 cup (1 stick) unsalted butter, melted – Make sure it’s completely melted for even distribution.
- 1 large egg – For binding the crust.
Filling:
- 8 ounces cream cheese, softened – Soften it to room temperature for easy mixing. I usually leave it out on the counter for an hour.
- 2 large eggs – These add richness and help the filling set.
- 1/2 cup (1 stick) unsalted butter, melted – Again, make sure it’s melted!
- 3 3/4 cups powdered sugar – This is what makes it gooey!
- 2 teaspoons ground cinnamon – For that classic cinnamon roll flavor.
- 1 teaspoon vanilla extract – A touch of vanilla enhances the overall flavor.
Cinnamon Sugar Topping (optional):
- 2 tablespoons granulated sugar
- 1 teaspoon ground cinnamon – A simple sprinkle adds extra cinnamon goodness!
How to Make It
Crust:
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking dish. This prevents sticking.
- In a large bowl, combine the cake mix, melted butter, and egg. Mix until just combined – don’t overmix!
- Press the mixture evenly into the prepared baking dish. Use your hands or the back of a spoon – get it nice and compact.
Filling:
- In a separate bowl, beat the softened cream cheese until smooth and creamy. A hand mixer works best here.
- Add the eggs one at a time, beating well after each addition.
- Stir in the melted butter, powdered sugar, cinnamon, and vanilla extract until the mixture is completely smooth and creamy.
Assemble:
- Pour the creamy filling evenly over the prepared crust.
Topping (Optional):
- If using, combine the granulated sugar and cinnamon. Sprinkle this mixture evenly over the filling.
Bake:
- Bake for 40-45 minutes, or until the edges are set and the center is just slightly jiggly. Don’t overbake – we want that gooey center!
- Let the bars cool completely in the pan before cutting. This allows them to set properly. Trust me, it’s worth the wait!

Substitutions & Additions
Feel free to experiment! You could add chopped nuts to the crust or filling, use brown sugar instead of some of the powdered sugar in the filling for a richer flavor, or even add a swirl of caramel sauce to the top before baking.
Tips for Success
- Don’t overmix the crust or filling – overmixing can lead to a tough texture.
- Make sure your butter is completely melted for even distribution in both the crust and the filling.
- Let the bars cool completely before cutting – this prevents them from crumbling.
- You can prepare the crust and filling ahead of time and assemble just before baking.
How to Store It
Store leftover bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. They are best enjoyed at room temperature.
FAQs
Q: Can I freeze these bars? A: Yes! Freeze them in an airtight container for up to 2 months. Thaw them overnight in the refrigerator before serving.
Q: What if my bars are overbaked? A: Overbaked bars will be dry. Try to avoid this by starting to check for doneness at 40 minutes, using a toothpick or cake tester.
Q: Can I use a different type of cake mix? A: Absolutely! Chocolate cake mix would make a delicious twist.
Q: Are these bars gluten-free? A: No, this recipe uses a standard yellow cake mix, which contains gluten. You would need to use a gluten-free cake mix for a gluten-free version.
