Ingredients

For the Cake Layers:

3 1/2 cups flour
1 tsp salt
1 tsp baking powder
3/4 tsp baking soda
1 1/2 cups soft butter
1 2/3 cups sugar
3 large eggs + 2 additional egg whites, at room temperature
1 Tbsp vanilla
1 1/2 cups buttermilk, at room temperature

For the Cinnamon Swirl:

1/2 cup light or dark brown sugar
1/3 cup flour
1 Tbsp cinnamon
1/4 cup melted butter

For the Vanilla Whipped Filling:

2 cups heavy whipping cream
1/2 cup powdered sugar
1/3 cup instant vanilla pudding mix (dry)
1 Tbsp vanilla

For the Cinnamon Buttercream:

3 sticks salted butter, very soft
6 cups powdered sugar
2 to 3 tsp ground cinnamon
2 tsp vanilla
4 to 6 Tbsp half n half, vanilla coffee creamer, or more as needed

Step-by-Step Instructions

Step 1: Prep the Dry Ingredients and Cream the Butter

Preheat your oven to 350 degrees. Line and spray three 9-inch cake pans. In a bowl, whisk together the flour, salt, baking powder, and baking soda, then set it aside. In a large mixer, beat the sugar and soft butter together on high for 2 to 3 minutes until it is smooth and creamy, making sure to scrape down the sides and bottom of the bowl.

Step 2: Mix the Wet and Dry Ingredients

Beat the eggs, additional egg whites, and vanilla into the creamed butter. Do not panic if the mixture looks curdled at this stage; this is a normal reaction between the butter and the eggs. Scrape down the sides and bottom of the bowl. Mixing on low speed, slowly add the dry ingredients to the bowl. Next, slowly add the buttermilk and mix just until everything is combined. Pour the finished batter evenly into your three prepared cake pans.

Step 3: Add the Cinnamon Swirl

In a small bowl, mix the brown sugar, flour, and cinnamon together. Pour the melted butter over the dry mixture and stir just until combined. Drop small spoonfuls of the swirl mixture evenly onto each of the three unbaked cakes. Use a knife to gently swirl the mixture through the cake batter.

Step 4: Bake and Freeze the Cake Layers

Bake the cakes at 350 degrees for 23 to 26 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for about 15 to 20 minutes before removing them to finish cooling completely. Once they are completely cool, wrap the cakes securely in plastic wrap and place them in the freezer for 4 hours, or ideally overnight.

Step 5: Prepare the Vanilla Whipped Filling

Using a cold bowl or a whisk attachment, mix the heavy whipping cream, powdered sugar, dry instant vanilla pudding, and vanilla together. Scrape down the sides and bottom of the bowl, then whisk the mixture on high for about 30 to 45 seconds until it is thick. Place the finished filling into a large piping bag.

Step 6: Whip the Cinnamon Buttercream

Using a paddle attachment, beat the very soft salted butter for 5 to 6 minutes, scraping the sides and bottom every minute until the butter becomes almost white. Add 2 cups of powdered sugar and mix on low until incorporated. Add 2 more cups of powdered sugar along with the vanilla, and continue mixing on low. Finally, add the last 2 cups of powdered sugar, the cinnamon, and 2 tablespoons of your liquid (half n half or creamer), mixing on low. Add any remaining liquid just one tablespoon at a time until you reach a smooth, soft, but not runny consistency.

Step 7: Assemble and Decorate

Take the frozen cake layers out of the freezer about 20 to 30 minutes before you are ready to frost them. Pipe a line of the cinnamon buttercream around the outer edge of the first cake layer to act as a protective dam. Fill the center inside the dam with the vanilla whipped filling. Repeat this process with the second layer. Place the top cake layer on, then cover the entire cake with a thin crumb coat to seal everything in. Place the cake in the fridge for 5 to 10 minutes to set, then slowly build your final frosting layers. Garnish the top with mini snickerdoodle cookies, cinnamon sticks, and cookie crumbs.

Expert Cooking Tips

Allow your eggs, egg whites, and buttermilk to come to room temperature before mixing to ensure a smooth, evenly baked cake.
The cake batter will naturally look somewhat curdled after adding the eggs to the butter; this is expected, so just proceed with the recipe.
Chilling your mixing bowl beforehand will help the heavy cream whip up much faster and hold its shape better.
Be patient when beating the butter for the frosting; it truly needs the full 5 to 6 minutes to aerate properly and turn that beautiful pale color.
Always add the liquid to your buttercream gradually, just one tablespoon at a time, so you have total control over the final consistency.
Creating a firm buttercream dam around the edge of the cake layers is essential to prevent the softer whipped vanilla filling from bulging out of the sides.

Variations to Try

Swap the vanilla coffee creamer in the frosting for a cinnamon or caramel-flavored creamer to add another layer of depth to the buttercream.
Use toasted, chopped pecans to decorate the bottom border of the frosted cake instead of crushed cookie crumbs.
For a slightly tangier filling, fold half a block of softened cream cheese into the whipped vanilla pudding mixture.

What to Serve With Snickerdoodle Layer Cake

A steaming mug of dark roast coffee or a creamy vanilla latte to complement the warm cinnamon spices.
A tall, ice-cold glass of whole milk.
A scoop of premium vanilla bean or cinnamon ice cream served alongside a thick slice.

Storage & Reheating

Refrigerator

Because the filling is made with fresh heavy whipping cream and pudding, this cake must be stored in the refrigerator. Keep it in a tall, airtight cake dome to prevent the frosting from absorbing fridge odors. It will stay fresh and moist for up to 4 days.

Freezer

This cake is incredibly freezer-friendly. The un-frosted layers are actually meant to be wrapped in plastic and frozen before assembly. You can also freeze leftover slices of the fully decorated cake in airtight containers for up to 2 months.

Reheating

Cake is best enjoyed at room temperature. If serving from the refrigerator, let the slices sit on the counter for about 20 to 30 minutes before eating to allow the butter in the cake and frosting to soften beautifully.

Frequently Asked Questions

Why do I need to freeze the cake layers before frosting?

Wrapping the completely cooled cakes in plastic wrap and freezing them for 4 hours or overnight traps the moisture inside the crumb. Furthermore, working with firm, frozen cakes makes stacking and frosting significantly easier, reducing the chance of tearing the delicate crumb.

Why does the batter look curdled after adding the eggs?

The batter will look curdled because of the emulsion process between the high volume of fat in the butter and the water content in the eggs. Once you slowly mix in the dry ingredients, the batter will smooth out perfectly.

What exactly is a buttercream dam?

A buttercream dam is a thick ring of frosting piped directly around the outer perimeter of a cake layer. It acts as a sturdy structural wall that holds in softer fillings—like the whipped vanilla center—preventing them from leaking out when the next heavy cake layer is placed on top.

Can I use regular milk instead of half n half in the frosting?

Yes, you can substitute regular milk for the half n half or vanilla coffee creamer. Just remember to add it very slowly, one tablespoon at a time, until the frosting reaches a soft, smooth consistency.

How should I decorate the finished cake?

For a bakery-quality finish, pipe swirls of the leftover cinnamon buttercream on the top of the cake, pressing a mini snickerdoodle cookie into each swirl. You can also place whole cinnamon sticks in the center and gently press crushed snickerdoodle crumbs around the bottom edge of the cake.
