There is something mighty comforting about a simple dessert that starts with a humble box of yellow cake mix and turns into a warm, vanilla-scented treat fit for National Vanilla Cupcake Day or any ordinary evening that needs brightening. This kind of casserole dessert has the same practical spirit many of us grew up with in Midwestern kitchens: a handful of pantry staples, one baking dish, and a sweet finish that fills the house with a bakery smell without a lot of fuss.

Serve this warm with a scoop of vanilla ice cream, a spoonful of whipped topping, or a drizzle of warm cream if you want to dress it up a bit. Fresh berries on the side are lovely for a little color and tartness, and a cup of coffee or cold milk makes it taste just right after supper or at a church potluck table.

5-Ingredient Oven Baked Vanilla Cake Mix Dessert

Ingredients

1 box (15.25 ounces) dry yellow cake mix

1 can (21 ounces) vanilla pudding or custard filling
1 cup milk
1/2 cup unsalted butter, melted
2 large eggs

Directions

1. Preheat the oven to 350°F and lightly butter or spray an 8x8-inch oven-safe glass casserole dish.

2. Pour the dry yellow cake mix powder evenly into the prepared casserole dish, then spoon the vanilla pudding or custard filling over the top in small dollops.

3. In a bowl, whisk together the milk, melted butter, and eggs until smooth, then pour this mixture evenly over the cake mix and pudding layer.

4. Use a spoon or spatula to gently spread and nudge everything together so the dry mix is moistened, but do not overmix. A few uneven spots are just fine.

5. Bake for 35 to 40 minutes, until the top is golden, the center is set, and the edges are lightly browned. Let it rest for 10 minutes before serving.

6. Spoon into bowls or cut into squares and serve warm, plain or with vanilla ice cream if you like.

Variations & Tips

Berry Topped: Scatter a cup of fresh or frozen blueberries or raspberries over the pudding layer before adding the milk mixture. That little burst of fruit gives the dessert a cobbler-like charm and balances the sweetness nicely.

Extra Vanilla Flavor: If you happen to have it on hand, stir 1 teaspoon of vanilla extract into the milk mixture. It is not necessary, but it does deepen that bakery-style vanilla taste for a special occasion dessert.

Texture Tip: Do not beat the mixture too much once the liquid goes into the dish. This dessert is at its best when it bakes up a little rustic, with tender soft spots and a lightly crisp golden top.

Make It Richer: Swap part of the milk for half-and-half if you want a more custardy result. That is especially nice when serving it warm with a scoop of ice cream on a chilly evening.

Pan Size Note: An 8x8-inch dish gives a thicker dessert, while a 9x9-inch dish will bake a bit faster and make slightly thinner squares. Start checking the center a few minutes early if using the larger pan.
