Instructions

1. Prepare Chocolate Sponge Batter

   In a mixing bowl whisk together sifted flour, cocoa powder, baking powder, baking soda, and salt. In a separate bowl beat eggs with sugar until light, then add melted butter, milk, and melted dark chocolate. Fold dry ingredients into wet until just combined.

   Time: PT20M

2. Bake Chocolate Sponge

   Divide batter evenly into two greased 9‑inch round pans. Bake at 350°F for 25 minutes, or until a toothpick comes out clean. Rotate pans halfway for even browning.

   Time: PT25M

   Temperature: 350°F

3. Cool Sponge Layers

   Remove cakes from pans, peel parchment, and let cool completely on a cooling rack.

   Time: PT15M

4. Prepare Brownie Batter

   Melt butter and dark chocolate together. Whisk in sugar, then eggs one at a time. Fold in flour and cocoa powder until just combined.

   Time: PT15M

5. Bake Brownie Slab

   Spread batter into a greased 9‑inch pan lined with parchment. Bake at 350°F for 30 minutes. The center should be set but still slightly soft.

   Time: PT30M

   Temperature: 350°F

6. Cool Brownie

   Transfer to a cooling rack and let cool fully.

   Time: PT15M

7. Prepare Cocoa Chiffon Batter

   In a bowl whisk together flour, cocoa, sugar, and salt. In another bowl beat egg whites with cream of tartar until stiff peaks form. Fold the egg whites into the dry mixture with melted butter and a splash of milk, being careful not to deflate.

   Time: PT20M

8. Bake Cocoa Chiffon

   Pour batter into an ungreased 9‑inch round pan. Bake at 325°F for 25 minutes. The cake should spring back when touched.

   Time: PT25M

   Temperature: 325°F

9. Cool Chiffon Layer

   After 10 minutes, run a knife around the edge, then carefully invert onto a cooling rack. Let cool completely.

   Time: PT15M

10. Make Dark Chocolate Ganache

    Heat 1 cup heavy cream in a saucepan until just simmering. Remove from heat and pour over chopped dark chocolate. Let sit 2 minutes, then whisk until glossy. Keep warm (around 120°F) for later pouring.

    Time: PT15M

11. Prepare Silky Chocolate Mousse

    Whisk remaining egg whites with a pinch of salt until soft peaks form. Melt 4 oz dark chocolate and fold into the whites with 1 cup heavy cream whipped to soft peaks. Chill for 20 minutes.

    Time: PT20M

12. Make Caramel Pockets

    Combine 0.5 cup sugar, 0.25 cup corn syrup, and 0.25 cup water in a saucepan. Cook over medium heat, swirling gently, until amber color forms (about 5 minutes). Remove from heat, stir in 2 tbsp butter, then let cool slightly before spooning small dollops onto parchment and refrigerating until firm.

    Time: PT20M

13. Prepare Marshmallow Fluff Layer

    In a microwave‑safe bowl melt marshmallow fluff with 2 tbsp butter for 30 seconds, stir, then microwave another 30 seconds. Whisk until smooth and glossy.

    Time: PT15M

14. Whip Chocolate Cream

    Chill a mixing bowl and whisk. Add 1 cup chilled whipping cream, 4 oz melted dark chocolate, and 2 tbsp powdered sugar. Whip to stiff peaks.

    Time: PT10M

15. Make Cookie Butter Crunch

    Melt 2 tbsp butter, stir in 0.5 cup cookie butter and 1 cup crushed chocolate cookies until a thick paste forms. Spread thinly on parchment and refrigerate until firm, then break into shards.

    Time: PT10M

16. Assemble the 24‑Layer Tower

    On a sturdy cake board, start with a chocolate sponge layer. Spread a thin layer of mousse, then add a brownie slab, a spoonful of caramel pockets, a dollop of marshmallow fluff, a chiffon layer, a stripe of whipped chocolate cream, a handful of chocolate shards, and a piece of cookie‑butter crunch. Repeat the sequence, alternating textures, until you have built 12 layers, then mirror the stack to reach 24 layers, pressing gently to keep layers even.

    Time: PT45M

17. Pour Warm Ganache Over the Top

    Slowly drizzle the warm ganache over the assembled tower, allowing it to cascade down the sides. Let the ganache set for 5 minutes.

    Time: PT5M

18. Torch the Top for Caramelized Finish

    Using a kitchen torch, lightly torch the marshmallow fluff and caramel pockets on the top tier until golden‑brown and slightly blistered.

    Time: PT5M
