This cake is the answer when you want homemade flavor without measuring several dry ingredients or waiting for a complicated batter to come together. A boxed yellow or butter cake mix provides a reliable base, while melted butter, eggs, sugar, and vanilla turn it into a rich dessert with the character of a classic butter cake.
The crumb is denser than a typical fluffy layer cake, but it is not heavy or dry. Each slice has a buttery center, golden edges, and enough sweetness to stand on its own without frosting.
It is also wonderfully flexible. Bake it in a Bundt pan for a pretty centerpiece or choose a 9 x 13-inch pan when you want easy cutting and serving at a gathering.

Ingredients You’ll Need
The ingredient list is short, but each item has an important role in the texture and flavor. Choose a standard yellow or butter cake mix weighing 15.25 to 16.25 ounces, and check the package before mixing so you know you have the correct size.
- Cake mix: This is the convenient foundation of the cake and gives it a consistent crumb.
- Unsalted butter: One cup, or 226 grams, supplies the deep buttery flavor and moist texture.
- Eggs: Four large eggs add structure, richness, and color. Room-temperature eggs blend more easily.
- Granulated sugar: One cup, or 200 grams, adds sweetness and supports the golden crust.
- Vanilla: One teaspoon rounds out the buttery flavor.
- Salt: Add 1/4 teaspoon if the cake mix is low in sodium; otherwise, it can be left out.
- Pan coating: Use butter or baking spray plus a little flour to help the cake release cleanly.
Because this formula uses butter rather than the oil or water sometimes called for on a cake-mix box, follow this recipe rather than the package directions. The added sugar is intentional and creates the sweet, rich profile associated with this style of cake.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C). Prepare a 10-inch Bundt pan by coating every groove with butter or baking spray, dusting it with flour, and tapping out the excess; if using a 9 x 13-inch pan, grease it thoroughly. Careful pan preparation matters because the batter is rich and needs a well-coated surface for easy release.
Step 2: Melt the unsalted butter, then set it aside for several minutes so it becomes warm rather than hot. Hot butter can affect the eggs when they are combined, while slightly cooled butter helps the ingredients emulsify into a smooth mixture.
Step 3: Add the four eggs, granulated sugar, vanilla extract, and cooled melted butter to a large mixing bowl. Beat until the mixture is blended and glossy, with the eggs and butter evenly incorporated.
Step 4: Add the yellow or butter cake mix and the optional 1/4 teaspoon salt. Mix just until no dry pockets remain and the batter looks smooth; prolonged beating can make the finished cake less tender.
Step 5: Scrape the batter into the prepared pan and spread it evenly. A spatula helps push the thick mixture into the Bundt grooves and smooth the top so the cake bakes at an even rate.
Step 6: Bake the cake at 350°F (175°C). A Bundt cake typically needs 40 to 50 minutes, while a 9 x 13-inch cake usually needs about 35 to 42 minutes.
Step 7: Test the center with a toothpick near the end of the baking time. Remove the cake when the top is golden and the toothpick comes out clean or with a few moist crumbs, rather than wet batter.
Step 8: Let the cake cool in the pan for about 15 minutes. Invert a Bundt cake onto a cooling rack and allow it to cool completely before slicing, since turning it out while very hot may cause cracking.
Pro Tips for the Best Butter Cake
Room-temperature eggs are one of the easiest ways to improve the batter. Cold eggs can make melted butter firm up into little pieces, but warmer eggs combine with the butter and sugar more smoothly.
Pay special attention to the center tube of a Bundt pan. Butter or spray it thoroughly, then dust the entire interior with flour, making sure flour reaches the narrow ridges and corners.
Do not overmix after adding the cake mix. Stop as soon as the batter is smooth, because extended mixing can develop the flour portion of the mix and produce a tougher crumb.
Use the toothpick test as a guide, but also look at the cake itself. A finished cake should have a golden top and edges that look set, while a few moist crumbs on the tester are welcome for a tender result.

Serving Ideas and Variations
This cake is flavorful enough to serve plain, but a simple presentation can make it feel party-ready. Place the cooled cake on a platter and add a light dusting of powdered sugar just before serving.
Fresh berries, sliced peaches, or lightly sweetened whipped cream bring a pleasant contrast to the dense crumb. A small scoop of vanilla ice cream also melts beautifully against a warm slice.
For a holiday spread, arrange thin slices beside other festive desserts such as this colorful Christmas cake. The neutral vanilla-butter flavor makes this cake a useful companion to brighter, fruitier, or spiced desserts.
You can also serve the cake as a simple afternoon treat with coffee or tea. Since the recipe yields 12 to 16 servings, it is a practical choice when several guests are expected.
Storage and Make-Ahead Advice
Let the cake cool completely before covering it. Store it at room temperature in an airtight container or under a cake cover, where it will remain enjoyable for several days.
Keep slices covered so the exposed crumb does not dry out. If desired, cut only what you plan to serve and leave the remaining cake whole, since a whole cake retains moisture better than many individual slices.
The cake is convenient to make ahead for a gathering because it needs about 15 minutes of preparation, 35 to 42 minutes in a 9 x 13-inch pan or 40 to 50 minutes in a Bundt pan, and about 15 minutes of cooling in the pan before the final cooling period.
