How to Make Lemon Gooey Bars
Step 1: Prepare the crust
In a mixing bowl, combine 1 box lemon cake mix, ½ cup melted butter, and 1 egg. Stir until a soft dough forms. Press evenly into a parchment-lined 9×13-inch pan.
Step 2: Make the topping
In another bowl, beat together 8 oz softened cream cheese and 2 eggs until smooth. Add 2 cups powdered sugar, 1 tsp vanilla extract, and lemon zest (if using). Mix until creamy.
Step 3: Assemble and bake
Pour the cream cheese mixture over the crust and spread evenly. Bake at 350°F (175°C) for 30–35 minutes, until the edges are golden but the center is still slightly soft.
Step 4: Cool and serve
Let bars cool completely. Dust with powdered sugar, slice into squares, and enjoy!

Recipe FAQ
1. Can I make these without cream cheese?
Not exactly—cream cheese is what gives the topping its gooey texture. You could try mascarpone for a similar result.
2. Do I need to refrigerate lemon gooey bars?
Yes, for best freshness. Store leftovers in the fridge, though they can sit out for a day.
3. Can I use homemade cake batter instead of cake mix?
Absolutely! Just make a basic lemon cake batter and use about 3 cups in place of the mix.
4. How do I know when they’re done?
The edges should be golden while the center is still soft and slightly jiggly—it will firm up as it cools.
5. Can I double this recipe?
Yes! Bake in two pans or use a sheet pan, adjusting baking time as needed.
