Autumn Harvest Spice Bars with Maple and Cinnamon

These harvest spice bars with cream cheese are an ideal treat for the cooler months. Made from spice cake mix and a creamy layer of sweetened cream cheese, they deliver warm autumn flavors in an easy-to-make bar. Whether you’re serving them at a family gathering, bringing them to a potluck, or baking a batch to enjoy throughout the week, these spice bars are comforting, rich, and reliably delicious.

If you enjoy spice-forward desserts, these bars are a great shortcut. The boxed spice cake mix provides a base full of cinnamon, nutmeg, and warm spices so you can skip measuring multiple spices while still getting a classic fall flavor. The cream cheese topping is velvety and sweet, balancing the spiced crust and adding a cheesecake-like texture that keeps every bite moist and satisfying.

One of the best things about this recipe is how simple it is to prepare. The base mixes together in one bowl, presses into a 9×13 pan, and the cream cheese topping is beaten smooth and spread over the crust. Bake until the edges are set and the center still jiggles slightly, then let the pan cool completely before cutting. These bars also freeze well, making them a convenient make-ahead dessert for holiday entertaining.

If you find yourself with extra boxes of spice cake mix, this recipe is an excellent way to use them. Boxed cake mixes can be a time-saver without sacrificing taste, and they pair particularly well with cream cheese for a quick layered dessert. If you prefer to make your own spice blend from scratch, you can adapt the crust to use a homemade spiced flour mixture, but the boxed mix keeps the method straightforward and dependable.

Harvest spice bars ingredients

• spice cake mix (about 30.5 ounces total; 2 boxes)
• unsalted sweet cream butter, melted
• eggs
• cream cheese, softened
• pure vanilla extract
• powdered (confectioners’) sugar

How to make harvest spice bars

1. PREPARE: Preheat the oven to 350°F. Line the bottom of a 9×13-inch baking dish with parchment paper and set it aside.
2. MIX DOUGH: In a large bowl combine the spice cake mix, melted unsalted butter, and one large egg. Mix until well combined and press the mixture evenly into the bottom of the prepared baking dish to form the crust.
3. MIX TOPPING: In a separate bowl, beat 8 ounces of softened cream cheese until smooth. Add two large eggs, beating in one at a time. Stir in 1/2 cup melted unsalted butter and 1 teaspoon pure vanilla extract until fully incorporated. Gradually add 4 cups confectioners’ sugar and beat until the mixture is smooth and creamy.
4. BAKE: Pour the cream cheese topping over the prepared crust and spread it into an even layer. Bake for 50–60 minutes, or until the edges are firm and set while the center still jiggles slightly when gently shaken.
5. SERVE: Allow the pan to cool completely to room temperature, then refrigerate if desired to help the bars set further. Cut into 2-inch squares and serve. Store in an airtight container for up to three days, or freeze for longer storage.

FAQs and tips

Can I use salted butter for this recipe?

It’s best to use unsalted butter. Salt levels in salted butter vary between brands and can alter the intended flavor balance. Unsalted butter gives you consistent control over saltiness in baked goods.

What is the best way to soften cream cheese?

Softening cream cheese ensures a smooth topping. Either leave the cream cheese at room temperature for about an hour or microwave it for about 10 seconds to slightly soften it—just enough to beat easily. Avoid overheating, which can make the texture runny.

How long will these spice bars last?

Stored in an airtight container, these bars keep well for about three days in the refrigerator or at room temperature in a cool place. For longer storage, freeze the whole pan or individual slices for up to one month.

Can I freeze them for later?

Yes. Wrap the cooled bars tightly in plastic wrap or place individual pieces in freezer-safe bags. They freeze well for about a month and are convenient to thaw overnight in the refrigerator before serving.
