Ingredients

1 box (15.25 oz) lemon cake mix
1 can (21 oz) lemon pie filling

Optional add-ins: 2 large eggs, 1/2 cup (1 stick) melted butter, 1 tablespoon fresh lemon zest, and powdered sugar for dusting.

Directions

Preheat oven to 350°F and lightly grease a 9×13-inch baking dish.
In a large bowl, stir together the lemon cake mix, eggs, and melted butter if using until a soft dough forms.
Press the dough evenly into the bottom of the prepared dish to form the base.
Spread the lemon pie filling evenly over the base.
Bake for 25 to 30 minutes, or until the edges are golden and the filling is set.
Let cool completely, then dust with powdered sugar and cut into squares.

Serving Ideas

These bars are lovely served with a cup of tea or coffee, and a dusting of powdered sugar makes them feel fit for company. For a cozy dessert plate, pair them with fresh berries or a small scoop of vanilla ice cream, or wrap them individually as homemade gifts.

Variations & Tips

Cake Mix Swap: Yellow or vanilla cake mix works beautifully if lemon cake mix isn’t available—add a tablespoon of lemon zest for extra brightness.
Filling Tip: Spread the lemon filling gently so it stays in an even layer over the base.
Add-Ins: A sprinkle of powdered sugar or a drizzle of simple glaze on top adds a pretty finish.
Storage: Cover leftovers tightly and refrigerate up to 4 days; the bars slice best when well chilled.
