Tennessee Mountain Stack Cake is a traditional Southern dessert made with thin cookie-like cake layers stacked with a rich spiced dried apple filling. The layers are firm when baked but soften beautifully as the apple mixture absorbs into them overnight, creating a moist, flavorful cake with deep molasses and spice notes. This heritage recipe is often prepared for gatherings and celebrations because it makes a large cake perfect for sharing.
Why You’ll Love This Recipe
This cake has a unique texture and flavor that stands out from ordinary layer cakes. The thin baked layers absorb the apple filling over time, resulting in a tender and deeply flavored dessert.
The combination of molasses, cinnamon, nutmeg, and dried apples creates a warm and comforting taste. It also keeps well in the refrigerator, allowing the flavors to develop even more after a day of resting.
Another reason to love this cake is its rustic charm. Each layer is handmade, rolled out like a cookie dough, and baked individually. The final stacked result is impressive, making it perfect for holidays, family gatherings, or special occasions.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
6 ounces unsalted butter (1 1/2 sticks), softened
10 ounces (1 1/4 cups) superfine granulated sugar
3/4 cup molasses
2 large eggs
1/2 cup buttermilk
For the Dried Apple Filling
8 to 12 cups dried apples
2 pounds (4 cups) superfine granulated sugar
2 teaspoons ground cinnamon
2 teaspoons ground nutmeg
2 tablespoons molasses
3 cups water
For Serving
confectioners’ sugar for dusting
Directions
Preheat the oven to 350°F (175°C) and place the oven rack in the middle position.
In a medium bowl, whisk together the flour, salt, baking soda, baking powder, and cinnamon until evenly combined. Set the mixture aside.
In the bowl of a stand mixer fitted with the paddle attachment, combine the softened butter and superfine sugar. Mix on medium speed until the mixture becomes moist and grainy.
Add the molasses and scrape down the sides of the bowl with a spatula to ensure everything is fully incorporated.
Add the eggs one at a time, mixing on low speed after each addition. Scrape the bottom and sides of the bowl to keep the batter smooth.
Gradually add the buttermilk and the dry ingredient mixture alternately, about one quarter at a time. Mix on low speed and scrape the bowl as needed. The finished dough should resemble a stiff, soft cookie dough.
Shape the dough into a ball, wrap it tightly in plastic wrap, and refrigerate for 30 minutes.
After chilling, divide the dough into 6 to 8 equal portions. Place each portion on a round sheet of parchment paper slightly larger than a 9-inch cake pan.
Roll each portion into a thin circle. Place a 9-inch cake pan over the rolled dough and trim around the edges to form even discs.
Transfer the parchment with the dough discs onto baking sheets. Bake for about 10 minutes or until the surface appears dry and a skewer inserted in the center comes out clean.
Slide the baked discs off the baking sheets and allow them to cool completely on a flat surface.
To make the apple filling, combine the dried apples, sugar, cinnamon, nutmeg, molasses, and water in a large heavy saucepan. Bring the mixture to a gentle simmer.
Once softened, transfer the mixture to a food processor and pulse until it becomes a thick apple paste.
To assemble the cake, place one cake layer on a serving plate and spread about 1 cup of apple filling evenly over the surface.
Continue stacking layers and spreading filling between each one until all layers are used. Do not spread apple filling on the top layer.
Wrap the entire cake tightly and refrigerate for up to 24 hours. This resting time allows the apple filling to soften the layers.
Before serving, dust the top with confectioners’ sugar.
Spiced Apple Stack Cake
Add 1/2 teaspoon ground cloves and 1/2 teaspoon allspice to the apple filling for a deeper spice flavor.
Walnut Apple Stack Cake
Stir 1 cup finely chopped walnuts into the apple filling for added texture and nutty flavor.
Brown Sugar Filling
Replace half of the granulated sugar in the filling with light brown sugar for a richer caramel-like taste.
Apple Butter Version
Mix 1 cup of apple butter into the filling for a more concentrated apple flavor.
Thinner Layer Cake
Divide the dough into 8 to 10 layers instead of 6 to create a taller cake with more apple filling between layers.
Storage/Reheating
Refrigerator
Wrap the cake tightly with plastic wrap or foil and store it in the refrigerator for up to 5 days.
Freezer
The cake can be frozen for up to 2 months. Wrap it tightly in plastic wrap and then in foil before freezing. Thaw overnight in the refrigerator before serving.
Serving Tip
This cake is traditionally served chilled or slightly cool. It does not require reheating.
FAQs
Why must the cake rest overnight?
The resting time allows the apple filling to soften the firm cake layers, turning them moist and tender.
Can I use fresh apples instead of dried apples?
Dried apples are essential because they create a thicker filling that gradually softens the cake layers.
How many layers should the cake have?
Traditional stack cakes usually have between 6 and 8 layers, but some bakers make up to 10 thinner layers.
Can I make the layers ahead of time?
Yes. The baked layers can be stored in an airtight container at room temperature for up to 2 days before assembling the cake.
What type of molasses works best?
Regular unsulphured molasses is ideal because it provides a rich flavor without overpowering bitterness.
Can I make this cake without a stand mixer?
Yes. You can cream the butter and sugar using a hand mixer or even mix by hand with a sturdy spoon.
Why is my dough so stiff?
The dough is supposed to be firm so it can be rolled thinly like cookie dough without sticking.
Can I freeze the apple filling?
Yes. The filling can be frozen for up to 2 months in an airtight container and thawed before using.
Why don’t we put filling on the top layer?
Traditionally the top is left plain and dusted with confectioners’ sugar to highlight the layered structure.
How do I know when the cake layers are done baking?
The surface should look dry and a skewer inserted in the center should come out clean.
