Snickerdoodle Cake Recipe Using Cake Mix

This snickerdoodle cake starts with a box of vanilla cake mix and gets its warm cinnamon flavor from a cinnamon-sugar swirl and a soft, buttery frosting. It bakes in a 9-by-13-inch pan, so it is easy to slice and serve without stacking cake layers.

Ingredients

1 box (15.25 oz / 432 g) vanilla or white cake mix
1 cup (240 ml) whole milk
½ cup (120 ml) neutral oil, such as canola or vegetable oil
3 large eggs, at room temperature
1 teaspoon (5 ml) vanilla extract
2 teaspoons ground cinnamon, divided
⅓ cup (67 g) granulated sugar
½ cup (113 g) unsalted butter, softened
3 cups (360 g) powdered sugar, sifted if lumpy
2 tablespoons (30 ml) milk, plus more as needed
⅛ teaspoon fine salt
Optional topping: 1 tablespoon (13 g) granulated sugar mixed with ½ teaspoon ground cinnamon

Instructions

Heat the oven to 350°F (175°C). Grease a 9-by-13-inch (23-by-33-cm) baking pan; for easier lifting, line it with parchment, leaving a little overhang. Let the eggs and butter come to room temperature while you prepare the pan.
In a small bowl, stir together the ⅓ cup (67 g) granulated sugar and 1½ teaspoons of the cinnamon. Set aside. Keep the remaining ½ teaspoon cinnamon for the frosting.
Put the cake mix, milk, oil, eggs, and vanilla in a large bowl. Beat with an electric mixer on low until the dry mix is moistened, then beat on medium for about 2 minutes, scraping down the bowl once. Stop when the batter looks evenly blended; prolonged mixing can make the cake less tender. Follow the box’s directions if its specific mixing instructions differ substantially.
Spread about half of the batter evenly in the prepared pan. Sprinkle the cinnamon-sugar mixture over it, keeping most of the mixture away from the edges so it does not stick to the pan. Spoon the remaining batter over the top in several dollops and gently spread it to cover. Drag a butter knife through the batter in a few loose curves to make a light swirl; avoid over-swirling, which can blend the layers together.
Bake for 30–35 minutes, starting to check at 30 minutes. The cake is ready when the center springs back lightly and a toothpick inserted into a plain cake area comes out clean or with a few moist crumbs. Do not use a cinnamon-sugar streak as the test spot, because it can look wet even when the cake is baked. If the top is browning quickly but the center is not done, loosely cover it with foil for the remaining bake time.
Set the pan on a rack and cool the cake completely, about 45 minutes. Frosting a warm cake will melt the butter and make the topping runny. For food safety, do not leave the finished cake at room temperature longer than 2 hours.
For the frosting, beat the softened butter on medium until smooth, about 1 minute. Add the powdered sugar, remaining ½ teaspoon cinnamon, salt, and 2 tablespoons milk. Mix on low until the sugar is incorporated, then beat on medium until fluffy, 1–2 minutes. If it is too stiff to spread, add milk 1 teaspoon (5 ml) at a time; if it is too soft, mix in powdered sugar 1 tablespoon (8 g) at a time.
Spread the frosting over the cooled cake. Sprinkle with the optional cinnamon sugar, if using, then cut into 12 squares. For cleaner slices, chill the frosted cake for 15 minutes and wipe the knife between cuts.

Tips

Use a cake mix close to 15.25 ounces. Some current mixes are smaller; a smaller box can make a slightly thinner cake and may bake faster, so begin checking several minutes early.
Room-temperature eggs blend more evenly into the batter. To take the chill off quickly, place the eggs in a bowl of warm—not hot—water for 5–10 minutes.
For a less sweet topping, skip the optional cinnamon-sugar garnish and use a thin layer of frosting. You can also use a prepared cream cheese frosting, though its tangy flavor will make the cake taste less like a classic cinnamon-sugar snickerdoodle.
Do not overfill the pan or stir the cinnamon layer fully into the batter. The 9-by-13-inch pan gives the cake room to bake evenly, and a light swirl keeps a distinct cinnamon-sugar ribbon.

Serving Suggestions

Serve the cake at room temperature so the crumb is soft and the frosting spreads easily with each bite. It pairs well with coffee, black tea, or a glass of milk. For a simple dessert plate, add sliced apples or pears, or serve a square with a small scoop of vanilla ice cream. If serving it chilled, let pieces sit out for about 15 minutes before eating so the butter-based frosting softens.

Variations

Make it as cupcakes: Divide the batter among lined muffin cups, filling each about two-thirds full. Add a small pinch of cinnamon sugar between two layers of batter in each cup, then bake at 350°F (175°C) for about 18–22 minutes, checking with a toothpick. The yield depends on the size of the mix and cups; begin checking early rather than relying only on the clock.

Add a cream cheese note: Beat 4 ounces (113 g) softened cream cheese with the butter before adding the powdered sugar. The frosting will be tangier and softer; keep the cake refrigerated and let it stand briefly before serving.

Use a spice blend: Replace the cinnamon in the swirl with 1½ teaspoons cinnamon plus a pinch each of nutmeg and cardamom. The cake will taste more warmly spiced, while cinnamon remains the main flavor.

Storage and Reheating

Because the basic frosting contains butter and milk but no cream cheese, the cake can be kept covered at cool room temperature for up to 2 days. Refrigerate it in an airtight container within 2 hours if your kitchen is warm, or for longer storage; it keeps well for about 4 days in the refrigerator. If you add cream cheese to the frosting, refrigerate the cake within 2 hours and use it within 4 days.

To freeze, wrap individual unfrosted or frosted slices tightly and freeze for up to 2 months; thaw overnight in the refrigerator or for about 1 hour at room temperature. This cake is best served at room temperature, so reheating is usually unnecessary. If you prefer a warm slice, microwave one piece for 10–15 seconds, checking before adding more time. Do not leave cake out for more than 2 hours total when serving.

Frequently Asked Questions

Can I use yellow cake mix?
Yes. Yellow cake mix works well and gives the crumb a slightly richer, more buttery taste. Use the same quantities of milk, oil, eggs, and vanilla, and check the cake at the early end of the baking range.

Can I make this cake without a mixer?
Yes. Whisk the cake batter by hand until smooth and evenly combined, taking care not to overmix. For the frosting, softened butter can be beaten with a sturdy whisk or wooden spoon, but it will take more effort to make it fluffy.

Why did the cinnamon sugar sink?
A little settling is normal, but a heavy layer may sink if the batter is particularly thin or the sugar is concentrated in one thick strip. Sprinkle it evenly over the first layer, leave the edges mostly clear, and spoon the second layer of batter on gently before making a few shallow swirls.

How do I know the cake is done?
Check the center with a toothpick in a spot without visible cinnamon sugar. It should come out clean or with a few crumbs, and the center should spring back lightly. Start checking at 30 minutes because ovens and cake mixes vary.

Can I make it ahead?
Yes. Bake the cake a day ahead, cool it completely, cover the pan, and frost it the next day. You can also bake and frost it ahead, then refrigerate it; let it stand at room temperature for about 15–20 minutes before serving for a softer texture.

Can I use a different pan?
A 9-by-13-inch pan is the most reliable size for this recipe. Two 8-inch round pans may work, but the bake time will change; begin checking early and avoid filling pans more than about two-thirds full. For cupcakes, use the variation instructions and check for doneness around 18 minutes.
