Tools You’ll Need
9-inch round cake pans (one or more)
Large mixing bowl
Electric mixer or sturdy whisk
Fine mesh sifter
Measuring cups and spoons
Wire racks or clean kitchen towels
4-quart saucepan
Wooden spoon or heat-safe spatula
Ingredients
Cake Batter
1 cup shortening
4 large eggs
3 cups plain flour
2 tablespoons baking powder
2 1/2 cups whole milk
1 tablespoon vanilla flavoring
1 tablespoon butter flavoring
2 cups sugar
Cooked Chocolate Icing
3 cups sugar
6 tablespoons cocoa powder
1 cup butter
1 can evaporated milk
Step-by-Step Instructions
Prepare the Batter
Sift the flour and baking powder together and set aside.
In a large bowl, cream the shortening and sugar until light and fluffy. This step matters more than it seems, as it gives the cake its delicate texture.
Add the eggs one at a time, beating well after each addition.
Add the flour mixture alternately with the milk, beating until fully blended and smooth.
Stir in the vanilla flavoring and butter flavoring until evenly incorporated.
Prepare the Pans
Use shortening to grease 9-inch cake pans, then lightly sprinkle with flour. You may also use a baking spray with flour.
Wash and dry the pans between each layer to prevent buildup, which can affect baking and browning.
Bake the LayersPreheat the oven to 375°F (190°C).
Spread about 1/2 cup of batter evenly into each prepared pan, creating a very thin layer.
Bake until lightly browned. The layers bake quickly, so keep a close eye on them.
Remove from the oven and place on wire racks or clean towels to cool slightly. You may begin assembling the cake as layers come out, if desired.
Cooked Chocolate Frosting
Make the Frosting First
Melt the butter in a 4-quart saucepan over medium heat.
Add the sugar, cocoa powder, and evaporated milk. Stir until well combined.
Bring the mixture to a rolling boil, then reduce the heat and cook for exactly 2 minutes, stirring constantly. This step requires focus and steady hands.
Remove from heat and allow the frosting to cool. The frosting will be thin, which is exactly what you want for spreading between many layers.
Assemble the Cake
Place the first cake layer on your serving plate.
Spread a generous amount of frosting over the top.
Continue stacking layers, frosting each one, until all layers are assembled.
Spread frosting over the top and sides of the cake, allowing it to naturally settle into the layers.
Tips for Success
Keep layers thin and even for the classic texture.
Do not overbake the layers; light browning is enough.
Stir the frosting constantly while cooking to avoid scorching.
Assemble the cake while layers are slightly warm for easier spreading.
Variations and Additions
Add a pinch of salt to the frosting to deepen the chocolate flavor.
Use dark cocoa powder for a more intense chocolate taste.
Replace part of the milk with buttermilk for a subtle tang.
Storage and Reheating
Store the cake covered at room temperature for up to 2 days.
For longer storage, refrigerate for up to 5 days and bring to room temperature before serving.
This cake does not require reheating and is best enjoyed at room temperature.

Frequently Asked Questions
Why is the frosting cooked on the stovetop?
Cooking the frosting creates a smooth, rich texture that soaks gently into the thin layers, which is essential for this style of cake.
Can I bake multiple layers at once?
Yes, if you have multiple pans, but always wash and prepare them again before each bake cycle.
Is this the same as a 14 layer chocolate cake?
Yes. Some versions count 14 layers, others 15, depending on batter portions. The method and spirit remain the same.
Does the frosting thicken as it cools?
It thickens slightly but stays spreadable. Its thin consistency is intentional.
This 15 Layer Chocolate Cake is not trendy, fast, or flashy. It is steady, confident, and deeply satisfying. A cake that proves tradition, when respected, never loses its power.
