These oven baked orange slice blondie bars are the kind of nostalgic shortcut dessert that turns a bag of old-fashioned candy into something surprisingly rich, chewy, and crowd-pleasing. The method is especially appealing when you want a quick pan dessert with very little measuring or fuss, and the whole orange slice candies melt and soften into bright, citrusy pockets throughout the bars. It has the spirit of a vintage church-supper or potluck bake, where convenience ingredients become more than the sum of their parts.
Serve these bars slightly warm or fully cooled with coffee, black tea, or a glass of cold milk. If you want to dress them up for company, add a small scoop of vanilla ice cream or a spoonful of lightly sweetened whipped cream, and for contrast you can pair them with fresh berries or a bowl of sliced oranges to echo the citrus flavor.
Oven Baked 5-Ingredient Orange Slice Blondie Bars
Servings: 12 bars
Ingredients
1 box yellow cake mix
2 large eggs
1/2 cup unsalted butter, melted
2 cups whole unwrapped orange slice candies
1 teaspoon vanilla extract
Directions
1. Preheat the oven to 350°F and lightly grease an oven-safe metal sheet pan or line it with parchment for easier removal.
2. In a large bowl, stir together the cake mix, eggs, melted butter, and vanilla until a thick blondie-style batter forms.
3. Fold in the whole orange slice candies, making sure they are distributed throughout the batter so every bar gets a few pieces.
4. Press the batter evenly into the prepared sheet pan, smoothing the top so the candies peek through here and there.
5. Bake for 20 to 25 minutes, or until the top is set and lightly golden at the edges. The candies will soften and settle into the bars as they bake.
6. Let the pan cool completely before slicing into bars, or serve slightly warm for a softer, gooier texture.
Variations & Tips
Use a smaller pan for thicker bars: If your sheet pan is quite large, the bars may bake up thin. A 9-by-13-inch pan will give you a thicker, chewier blondie texture and more pronounced candy pockets.
Watch the candy placement: Try to keep a few orange slice candies near the top for a pretty finish, but avoid clustering too many in one spot or the bars can bake unevenly and become overly sticky in patches.
Add a little crunch: If you do not mind moving beyond five ingredients, a small handful of chopped pecans or walnuts adds contrast and works nicely with the orange flavor.
Cut clean slices: For neater bars, let the pan cool fully and use a lightly greased knife. Because the candies stay soft, wiping the blade between cuts helps keep the edges tidy.
Lean into the citrus: A little orange zest in the batter or a very light drizzle of simple orange glaze over the cooled bars can make the flavor taste brighter and less candy-like while still keeping the recipe easy.
