These oven-baked harvest corn blondie bars are the kind of playful seasonal treat that turns a bag of autumn candy into a simple, chewy dessert with very little effort. Blondies are essentially vanilla-forward bar cookies with a soft, buttery crumb, and here the familiar sweetness of harvest corn candies melts into the batter for a festive pan of bars that feels nostalgic, colorful, and perfectly suited to fall baking.
Serve these bars slightly warm or fully cooled, cut into small squares since they are quite sweet. They pair especially well with black coffee, hot apple cider, or a glass of cold milk. For a dessert platter, add fresh apple slices or a scoop of vanilla ice cream to balance the richness and make them feel a bit more special.
Oven-Baked 5-Ingredient Harvest Corn Blondie Bars
Servings: 16 bars
Ingredients
1 box yellow cake mix, about 15.25 ounces
Directions
1. Preheat the oven to 350°F. Lightly grease a rimmed metal sheet pan or line it with parchment for easier removal.
2. In a large mixing bowl, stir together the yellow cake mix, eggs, melted butter, and vanilla extract until a thick blondie batter forms.
3. Fold in 1 cup of the harvest corn candies, saving the remaining 1/2 cup for the top so the finished bars have visible pops of color.
4. Press the batter evenly into the prepared sheet pan. Scatter the remaining candies over the top and gently press them in so they stay in place as the bars bake.
5. Bake for 18 to 24 minutes, or until the edges are lightly golden and the center looks set. The candies on top will soften and lightly melt into the surface.
6. Cool the pan completely before cutting into bars. For cleaner slices, let the bars rest at least 1 hour before serving.
Variations & Tips
Use a smaller pan for thicker bars: If you prefer a thicker, gooier blondie, bake the batter in a smaller metal baking pan instead of a larger sheet pan. You may need to add a few extra minutes to the baking time, so watch for set centers and lightly browned edges.
Add a pinch of salt: A small pinch of kosher salt in the batter helps balance the sweetness of both the cake mix and the harvest corn candies. This is especially helpful if you want the vanilla and buttery notes to come through more clearly.
Try white chocolate chips: If you do not mind going beyond five ingredients, a handful of white chocolate chips makes these bars even richer and gives the candy-studded top a bakery-style finish.
Do not overbake: Blondies continue to firm up as they cool, so it is better to pull the pan when the center is just set rather than fully dry. Overbaking can make the bars crumbly instead of soft and chewy.
Storage: Keep the cooled bars in an airtight container at room temperature for up to 3 days. Separate layers with parchment paper so the candy tops do not stick together.
