👨‍🍳 Instructions

1. 1--- Make the cookie layer ---
2. 2Line an 8" cake pan with a parchment round. Preheat the oven to 350°F.
3. 3Cream 4 ounces butter with 2 ounces granulated sugar and 4 ounces brown sugar until light and fluffy. Add 1 egg and 1 teaspoon vanilla extract and mix until combined. Add 5 ounces all-purpose flour, ½ teaspoon baking soda and ½ teaspoon salt. Add 6 ounces mini chocolate chips all at once and mix until combined
4. 4Spread the dough into the cake pan. The dough should be about 1/2" thick (if you have excess dough use it to make cookies).
5. 5Bake until the middle of the cookie puffs up a little and then collapses, about 20 minutes.
6. 6Cool completely in the pan. Flip the pan over and bang one edge of the pan a couple of times. The cookie should loosen and fall out. Set aside at room temperature until ready to assemble the cake.
7. 7--- Bake the Cake ---
8. 8Line two 8"x3" cake pans with parchment rounds or butter and flour the bottom of the pan only. Preheat the oven to 350°F.
9. 9Toss 8 ounces mini chocolate chips with 1 tablespoon water until moistened. Sprinkle 1 teaspoon all purpose flour over the chips and toss to distribute the flour. Set the chips aside while you make the cake batter.
10. 10Mix 1 recipe Vanilla Cake according to the recipe, folding the chocolate chips into the batter just before the whipped egg whites. Pour 1/3 of the batter into one pan and 2/3 of the batter into the other pan. Spread the batter evenly and bake until the cake springs back when lightly pressed, about 25 minutes depending on pan size.
11. 11Cool the cakes in the pans for 10 minutes. Run a small spatula around the cakes and remove them from the pans. Cool the cakes completely. Wrap each cake in plastic and refrigerate for 4 hours or overnight (see note 1).
12. 12--- Make the Brown Sugar Buttercream ---
13. 13Make 1 recipe Italian Meringue Buttercream according to the recipe. Mix 2 tablespoons molasses into the finished buttercream. Divide the buttercream in 1/2, reserve one 1/2 for icing the cake, use the remaining for filling.
14. 14--- Assemble the Cake ---
15. 15Make 1 recipe simple syrup (with rum) according to the recipe. Trim the sides of the cake to remove excess brown edges. Split the larger cake in two, horizontally, you will now have a total of three cake layers.
16. 16Place the chocolate chip cookie layer on a serving platter or cardboard cake circle. Spread 1 cup Dark Chocolate Ganache evenly over the cookie. Place one of the cake layers on the cookie. Brush the layer generously with rum syrup. Spread 1/2 of the buttercream reserved for the filling onto the cake layer.
17. 17Place another cake layer, sprinkle with syrup and spread with remaining filling. Top with the last cake layer and sprinkle that layer with syrup.
18. 18If the cookie base is bigger than the cake layers you can trim the cookie so its even with the cake layers.
19. 19Crumb coat the cake with a thin layer of buttercream and chill until the crumb coat is set. Ice with a final coating of buttercream, reserving a little buttercream for decoration. Pipe a border around the top edge of the cake and decorate with mini chocolate chips.
20. 20The cake will keep at room temperature for several days.
