Method
 

Make the Pie Crust (if homemade)
  1. In a bowl, combine 220 g (1 ¾ cups) flour and ½ tsp salt. Cut in 150 g (⅔ cup) cold butter until crumbly. Add 2–3 Tbsp ice water until dough just comes together. Shape into a disk, wrap, and chill for 30 minutes.
  2. If using store-bought crust, let it soften for 10–15 minutes before rolling later.
Make the Apple Pie Filling
  1. Melt 40 g (3 Tbsp) butter in a wide skillet over medium-low heat. Add 90 g (scant ½ cup) brown sugar, 1 ¼ tsp cinnamon, ¼ tsp nutmeg, and ¼ tsp salt. Stir until glossy and bubbling (about 2 minutes).
  2. In a small bowl, whisk 15 g (1 ½ Tbsp) cornstarch and 10 g (1 Tbsp) flour into 90 ml (⅓ cup + 1 Tbsp) apple cider until smooth, then pour into the pan. Stir until thickened (less than 1 minute).
  3. Add 3 medium diced apples (≈ 480–500 g) and cook 5 minutes, tossing gently until apples are tender on the edges but still slightly crisp inside.
  4. Spread onto a plate and cool completely before layering.
Make the Cinnamon Cake Layers
  1. Preheat oven to 350°F (177°C). Grease and line two 6-inch round pans with parchment.
  2. Whisk 220 g (1 ¾ cups + 1 Tbsp) flour, 1 ½ tsp baking powder, ¼ tsp baking soda, ¾ tsp salt, 1 ¾ tsp cinnamon, ⅛ tsp nutmeg, and ⅛ tsp allspice; set aside.
  3. In a mixer, cream 150 g (⅔ cup) butter, 200 g (1 cup) sugar, and 65 g (⅓ cup) brown sugar until light and fluffy (2–3 minutes).
  4. Add 2 eggs one at a time, then 1 ½ tsp vanilla.
  5. Alternate adding dry ingredients with 160 ml (⅔ cup) buttermilk, beginning and ending with dry.
  6. Fold in 100 g (about ⅔ medium apple) finely diced apple.
  7. Divide evenly between pans and bake 35-38 minutes until a toothpick comes out clean.
  8. Cool 10 minutes, then transfer to racks to cool completely.
Roll and Bake the Pie Crust Shapes
  1. Roll chilled dough to ⅛-inch thick. Cut small apples or rustic shards.
  2. Brush with 1 egg + 1 Tbsp water and bake at 375°F (190°C) for 10–15 minutes until golden and crisp.
Make the Cinnamon Buttercream
  1. Beat 450 g (2 cups) butter until smooth and fluffy (2–3 minutes).
  2. Gradually add 300 g (2 ⅔ cups) powdered sugar, beating between additions.
  3. Mix in 2 tsp vanilla, 1 Tbsp cinnamon, and a pinch of salt.
  4. Beat on high 3–4 minutes until light and airy.
Assemble and Decorate
  1. Level and slice each cake layer in half for 4 thinner layers total.
  2. Place one layer on a board. Pipe a ring of buttercream around the edge and spoon in apple filling. Repeat for all layers, finishing with cake on top.
  3. Chill 30 minutes, then frost the entire cake with remaining buttercream.
  4. Decorate with pie-crust apples or shards.
Tips & Tricks
  1. Chill before stacking: Cool the cake and apple filling completely before assembling to prevent slipping.
  2. Even layers: Weigh your batter before baking for uniform thickness.
  3. Stronger flavor: Bake the cake a day ahead — the spices deepen overnight.
  4. Buttercream barrier: Pipe a sturdy dam to keep the apple filling contained.

Notes

Storage & Make-Ahead

At room temperature:
Keeps up to 3 days covered in a cake carrier or under a dome in a cool kitchen.
Refrigerated:
Up to 5 days — bring to room temp 1–2 hours before serving so the buttercream softens again.
Freezing:
Unfrosted cake layers can be wrapped well and frozen up to 2 months. Thaw overnight in the fridge before assembling.
Make-ahead timeline:
  • Day 1: Bake cake layers + make apple filling (store filling in fridge once cooled).
  • Day 2: Make buttercream, assemble, and decorate.
Avoid sogginess:
Always cool the apple filling completely before layering — any warmth will melt the buttercream and soften the cake.
