This pecan pie cake recipe combines a tender butter-pecan cake with a rich, chewy pecan-pie topping in one easy 9 x 13-inch dessert. Made with a butter pecan cake mix, chopped pecans, corn syrup, butter, and vanilla, it takes about 15 minutes to prepare and 55–60 minutes of oven time.
The result is a warm Southern-style cake with a soft, buttery crumb and a glossy pecan topping that tastes like your favorite holiday pie. Let it cool for at least one hour before slicing so the topping can finish setting, then serve each square plain, with whipped cream, or alongside vanilla ice cream.

This pecan pie cake is the best of two classic desserts in a single baking dish. The bottom is soft and buttery, while the top has the caramel-like sweetness, toasted nut flavor, and tender chew associated with a traditional pecan pie.
It is also remarkably practical for entertaining. The cake serves about 12–16 people, travels well once cooled, and can be cut into neat squares for a holiday buffet, church supper, birthday table, or autumn potluck.
Unlike a pastry pie, this recipe begins with a convenient cake mix, so there is no crust to roll, chill, or repair. If you enjoy easy desserts built around familiar pantry ingredients, you may also like this apple pie cake mix dessert for another simple occasion-ready treat.
Ingredients You’ll Need
The cake layer needs one package of butter pecan cake mix, traditionally 18.25 ounces, plus 1 cup water, 1/2 cup vegetable oil, 3 large eggs, and 1 cup chopped pecans. This combination creates a moist cake with nutty flavor in every bite.
For the pecan-pie topping, gather 1 cup granulated sugar, 1 cup light corn syrup, 3 large eggs, 1/3 cup melted unsalted butter, 1 teaspoon vanilla extract, and another 1 cup chopped pecans. The eggs help the topping set, while butter and vanilla round out its rich flavor.
- Use a 9 x 13-inch baking dish and grease it before adding the batter.
- Measure the corn syrup carefully so the topping has the right consistency.
- Keep the pecans chopped fairly small for easy slicing and balanced texture.
- If possible, use the traditional 18.25-ounce cake mix for a fuller cake layer.
Many modern cake mixes are approximately 15.25 ounces. That smaller package can still work, but the finished cake layer may be slightly thinner than the traditional version.
How to Make It Step-by-Step
Step 1: Heat your oven to 350°F and grease a 9 x 13-inch baking dish. If you want especially fragrant pecans, toast the chopped nuts briefly in a dry skillet or in a 350°F oven, then cool them completely before adding them to the batter.
Step 2: Add the butter pecan cake mix, water, vegetable oil, and 3 large eggs to a large mixing bowl. Beat until the mixture is smooth and evenly combined, then stir in 1 cup of chopped pecans without overmixing.
Step 3: Spread the batter into the prepared baking dish and smooth the surface with a spatula. Bake for approximately 30 minutes, watching for a partially set cake that has begun to firm but is not fully baked through.
Step 4: While the cake is in the oven, prepare the topping. Whisk the granulated sugar, light corn syrup, 3 eggs, melted unsalted butter, and vanilla extract in a bowl until smooth, then stir in the remaining 1 cup of chopped pecans.
Step 5: Carefully remove the partially baked cake from the oven. Spoon or pour the pecan mixture evenly over the surface, working gently so the topping does not sink in one concentrated spot.
Step 6: Return the dish to the oven and bake for another 25–30 minutes. The topping should look set around the edges while remaining only slightly loose in the center; it will continue to firm as it cools.
Step 7: Place the baking dish on a cooling rack and leave the cake undisturbed for at least 1 hour. Once cool, slice it into 12–16 squares and serve plain, with whipped cream, or with vanilla ice cream.
Pro Tips for the Best Pecan Pie Cake
Toasting the pecans is optional, but it adds a deeper roasted flavor that makes the dessert taste especially special. Spread the chopped nuts in a dry skillet over moderate heat or on a baking sheet in a 350°F oven, and cool them before mixing them into either layer.
Do not judge doneness by waiting for the center to become completely rigid. The pecan topping is supposed to be slightly loose in the middle when it leaves the oven, because residual heat and cooling will finish the setting process.
For clean slices, use a sharp knife and wipe the blade between cuts. If the cake feels too soft to portion, give it more cooling time rather than returning it to the oven, which can make the topping dry or overly firm.
When preparing the cake mix, scrape the sides of the bowl so the oil and eggs are fully incorporated. An evenly mixed batter helps the cake bake uniformly beneath the sweet pecan layer.
Serving Ideas for Any Occasion
Serve this cake at room temperature for the clearest contrast between its tender crumb and chewy topping. A spoonful of softly whipped cream adds lightness, while vanilla ice cream melts into the warm pecan flavors and makes each bite feel like a complete celebration.
For a holiday table, arrange the squares on a large platter and add a few whole pecans around the edges. You can also serve smaller pieces on a dessert buffet because the flavor is rich and satisfying without requiring a large portion.

Storage and Make-Ahead Advice
Cool the cake completely before covering it. Store it in the baking dish with a tight cover, or transfer individual squares to an airtight container.
For the best texture, serve the cake within a few days and keep it refrigerated if your kitchen is warm. Allow chilled pieces to sit briefly at room temperature before serving, or warm them gently and top with ice cream.
This is a useful make-ahead dessert because the cake needs at least one hour of cooling before slicing. Bake it earlier in the day, let it cool fully, and cut it shortly before guests arrive.

Final Thoughts
This pecan pie cake recipe delivers classic Southern comfort with an easy cake-mix method. Its soft butter-pecan base, glossy nut topping, and simple preparation make it a dependable choice whenever you want a dessert that feels homemade and festive.
