From Start to Finish: Lemon Gooey Bars

Step 1: Prepare Your Oven and Pan
Preheat your oven to 350°F (175°C). Grease or line your 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy bar removal.
Step 2: Make the Base
In a large mixing bowl, combine the lemon cake mix, softened butter, and the egg. Use an electric mixer or whisk to blend until a smooth, thick batter forms. It will be thick but spreadable.
Step 3: Spread the Base Layer
Press the batter evenly into the prepared baking pan, creating a smooth and even layer. This forms the sturdy but tender base of your Lemon Gooey Bars.
Step 4: Add the Gooey Layer
In a separate bowl, pour in the sweetened condensed milk and fold in the white chocolate chips gently using your spatula. Spread this mixture evenly over the lemon cake base layer.
Step 5: Bake to Perfection
Bake in the preheated oven for about 25-30 minutes. The edges should be golden brown, and the center should be set but still slightly soft to the touch—this ensures the gooey texture you’re aiming for.
Step 6: Cool and Slice
Allow the bars to cool completely in the pan on a cooling rack. Once cool, use the parchment paper overhang to lift the bars out of the pan. Slice into squares and serve.
Variations for Dietary Needs

- Dairy-free: Substitute the unsalted butter with coconut oil or a plant-based butter alternative, and use dairy-free white chocolate chips.
- Lower sugar: Choose a lemon cake mix with reduced sugar, and opt for sugar-free white chocolate chips.
- Gluten-free: Use a gluten-free lemon cake mix for a safe and delicious version.
- Nut-free: This recipe is naturally nut-free, but check your cake mix and chocolate chips to ensure no cross-contamination.
Avoid These Traps
-
Don’t overbake your bars. Baking too long will cause them to dry out, losing the signature gooey texture.
-
Ensure your butter is softened—not melted—before mixing to maintain the proper consistency.
-
Use the exact size pan recommended. Using a smaller pan will make the bars thicker and may require longer baking time, while a larger pan will result in thinner bars.
-
Don’t skip the parchment paper or greasing step; otherwise, the bars may stick and break apart when slicing.
Store, Freeze & Reheat
Store your Lemon Gooey Bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week—the cooler temperature helps maintain their shape and freshness.
You can also freeze the bars by wrapping them tightly in plastic wrap and then placing them in a freezer-safe bag or container. Freeze for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator, then warm slightly in the microwave for 10-15 seconds if you prefer them soft and gooey.
Your Questions, Answered
Can I use regular chocolate chips instead of white chocolate?
Absolutely! Dark or milk chocolate chips will provide a different flavor profile but will still complement the lemon beautifully. Just keep the quantity the same.
How do I know when the bars are done baking?
The edges will be golden brown and the center should look set but slightly soft. A toothpick inserted in the middle may come out with a few moist crumbs but no raw batter.
Can I make these bars ahead of time for a party?
Yes! These bars actually taste great when made a day in advance as the flavors meld together. Just store them covered at room temperature or in the fridge if it’s warm.
What’s the best way to get clean slices?
Use a sharp knife and wipe it clean between cuts. For even neater slices, chill the bars for about 30 minutes before slicing.
