These easy pumpkin bars are the kind of old-fashioned dessert that earns a permanent spot in the family recipe box. With just four ingredients, they come together fast on a busy weeknight, but they still have that nostalgic potluck feel that makes people come back for seconds. The spice cake mix and pumpkin make a soft, moist bar with cozy fall flavor, and a thick layer of cream cheese frosting gives them that classic finish that never goes out of style.
Serve these bars chilled or at cool room temperature with coffee, hot tea, or a glass of milk. They fit right in on a holiday dessert table, but they are just as good packed up for a work potluck, church supper, or family reunion. If you want to dress them up a little, a light sprinkle of cinnamon on top or a few chopped pecans on the side pairs nicely without making the recipe any more complicated.
Oven Baked 4-Ingredient Pumpkin Bars
Servings: 15 bars
Ingredients
1 box spice cake mix
1 can (15 oz) pumpkin puree
3 eggs
1 tub cream cheese frosting
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch glass baking dish.
2. In a large mixing bowl, stir together the spice cake mix, pumpkin puree, and eggs until the batter is smooth and fully combined.
3. Spread the batter evenly into the prepared glass dish.
4. Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
5. Let the pumpkin bar layer cool completely in the dish for at least 1 hour. For the cleanest slices, chill the bars before frosting and cutting.
6. Spread the cream cheese frosting evenly over the cooled bars, then cut into squares and serve.
Variations & Tips
Cool Completely First: Make sure the bars are fully cooled before adding the frosting so it stays thick and creamy instead of melting into the top.
For Cleaner Slices: If you have time, chill the frosted bars before cutting. Cold bars slice much more neatly, which is especially helpful if you're taking them to a gathering.
Make It for a Crowd: These bars travel well in the baking dish, so they are great for potlucks and family parties. You can make them a day ahead and keep them covered in the refrigerator until serving time.
Simple Garnish: A dusting of cinnamon or a small sprinkle of chopped pecans on top adds a little extra fall flavor without changing the easy four-ingredient base.
