Lemon Gooey Butter Cake has a buttery yellow-cake base, a soft lemon cream-cheese filling and a delicate golden top. Fresh zest gives it a bright citrus flavor without turning the filling watery. It is a rich, low cake that cuts into little squares, rather than a tall, fluffy layer cake.
The base starts with a box of cake mix, but you will use it dry to make a thick dough. A separate cream-cheese mixture goes on top. As the cake bakes, the edges set while the middle stays soft. Cooling and chilling are part of the recipe, so allow time for both before you plan to serve it.
Questions You May Have About This Recipe
Is gooey butter cake supposed to be underbaked?
No. The filling should be soft because of its ingredients, not because the eggs are raw. Look for set edges and a center that moves slightly as one piece. It should not slosh or ripple, and the center should reach at least 160°F.
Can I use a smaller box of cake mix?
Check the weight, not just the box size. This recipe uses 15.25 ounces, or 432 grams. If your box is smaller, add extra dry mix from a second box to reach that weight. Do not add the oil or water listed on the package.
Can I use lemon cake mix?
A yellow mix lets the fresh lemon zest stand out. A same-weight lemon mix will give a stronger, sweeter lemon flavor, but different brands may bake a little differently.
Can I make it the day before?
Yes. Refrigerate the fully cooled cake, covered, and cut it the next day. Add a light dusting of powdered sugar just before serving, if you like.
What You Need to Make Lemon Gooey Butter Cake
As an Amazon Associate I earn from qualifying purchases.
For the base, you need yellow cake mix, melted unsalted butter and an egg. The filling uses full-fat block cream cheese, two more eggs, more melted butter, powdered sugar, fresh lemon zest, a little lemon juice and vanilla. The exact amounts are in the printable recipe below.
Have a 9-by-13-inch metal baking pan at least 2 inches deep, parchment paper, two bowls, a hand mixer, a spatula, a fine grater and an instant-read thermometer ready. Use softened cream cheese so it blends smoothly. Avoid spreadable cream cheese from a tub.
How to Make Lemon Gooey Butter Cake
Heat the oven to 350°F and line your prepared pan with parchment. Mix the dry cake mix with butter and one egg, then press the thick dough evenly over the bottom. Use the back of a spoon or lightly greased fingertips to reach the corners.
Beat the cream cheese until smooth before adding the eggs. Mix in the remaining filling ingredients, adding the powdered sugar gradually on low speed. Spread this mixture over the base without stirring the two layers together. Bake until the edges are golden and set, using the doneness cues in the card rather than looking for a dry toothpick.
Let the cake cool on a rack for about an hour, then refrigerate for at least an hour before slicing. The filling firms as it cools. For tidy squares, lift the cake out with the parchment and wipe the knife between cuts.
Tips for a Soft, Gooey Center
Measure the lemon juice rather than pouring it in freely. Extra liquid can make the filling slow to set. Grate only the yellow skin of the lemon; the white pith is bitter. Let melted butter cool before mixing it with the eggs. Start checking the oven early, especially with a dark metal pan, and loosely tent the top if the edges brown too quickly.

Lemon Gooey Butter Cake
A buttery yellow-cake base topped with a soft lemon cream-cheese layer and a delicate golden crust. Cool fully before cutting into small, rich squares.
Ingredients
- For the base:
- 1 box (15.25 ounces / 432 g) yellow cake mix, dry
- 1/2 cup (113 g) unsalted butter, melted and cooled
- 1 large egg
- For the filling:
- 8 ounces (226 g) full-fat block cream cheese, softened
- 2 large eggs
- 1/2 cup (113 g) unsalted butter, melted and cooled
- 3 1/2 cups (420 g) powdered sugar, sifted
- 1 tablespoon finely grated lemon zest
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract
- Optional: powdered sugar for dusting
Instructions
- Heat the oven to 350°F (175°C). Lightly grease a 9-by-13-inch metal baking pan, at least 2 inches deep, and line with parchment, leaving an overhang.
- Mix the dry cake mix, 1/2 cup melted butter and 1 egg until a thick dough forms. Press evenly across the bottom of the pan. Do not prepare the cake mix using the package directions.
- Beat the softened cream cheese until smooth. Beat in the 2 eggs one at a time, then the remaining 1/2 cup melted butter, lemon zest, lemon juice and vanilla. On low speed, gradually mix in the powdered sugar until smooth.
- Spread the filling evenly over the base. Bake for 40–45 minutes, checking from 35 minutes. The edges should be set and golden, and the center should jiggle slightly as one piece, not ripple like liquid. A thermometer in the center should reach at least 160°F. If needed, loosely tent with foil and bake a few minutes longer.
- Cool in the pan on a rack for about 1 hour, then refrigerate for at least 1 hour to firm up before slicing. Lift out with the parchment and cut into 16 squares. Dust lightly with powdered sugar if desired.
Notes
Use a 15.25-ounce cake mix; smaller boxes need extra dry mix to reach 432 g. Do not use spreadable tub cream cheese. The center should be soft but cooked, never liquid or raw. Refrigerate covered for up to 4 days. Freeze individual squares for up to 2 months and thaw in the refrigerator. Keep total room-temperature time under 2 hours. Total time includes 2 hours of cooling and chilling.
Storage and Serving
Refrigerate the cake in a covered container for up to 4 days. For longer storage, wrap individual squares and freeze for up to 2 months. Thaw in the refrigerator. Serve chilled for a firmer filling or let portions stand briefly before serving for a softer texture. Keep total room-temperature time under 2 hours.
