Ingredients
Ingredient | Amount | Notes
Lemon cake mix | 1 (15.25 oz) box | Any brand works
Lemon pie filling | 1 (21 oz) can | Not pudding—pie filling
Unsalted butter | ½ cup (1 stick) | Melted
That’s it. No eggs. No extra sugar. No complicated steps.
Instructions / Method
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line with parchment paper.
Step 2: Prepare the Crumb Mixture
In a medium bowl, combine:
Lemon cake mix
Melted butter
Stir with a fork until the mixture resembles coarse crumbs. It should hold together when pressed but still look crumbly.
Step 3: Press the Crust
Reserve 1 cup of the crumb mixture for the topping. Press the remaining mixture firmly into the bottom of the prepared pan. Use the bottom of a measuring cup to press evenly.
Step 4: Add the Filling
Spread lemon pie filling evenly over the crust.
Step 5: Add the Topping
Sprinkle the reserved crumb mixture evenly over the pie filling.
Step 6: Bake
Bake for 25–30 minutes, until the topping is golden brown and the filling is bubbly around the edges.
Step 7: Cool Completely
Let the bars cool completely in the pan on a wire rack. This is essential—the filling needs time to set.
Step 8: Slice and Serve
Slice into squares and serve. Dust with powdered sugar if desired.
