To make the cake:
Preheat oven to 350 degrees F. Grease three (or two if that's all you have) 6-inch round cake pans and line the bottoms with parchment paper. (See Notes)
In the bowl of a stand mixer fitted with a paddle attachment, beat butter and sugars on high speed until pale and creamy, about 3-4 minutes. Scrape down the bowl as needed.
Add the vanilla and then the eggs and yolks one at a time, mixing after each.
In a separate bowl, combine the cake flour, baking powder, baking soda, salt and nutmeg. Add to the mixer in 3 additions, alternating with the buttermilk, scraping down the bowl as needed. Mix in the bourbon.
Divide the batter evenly between the prepared cake pans and bake until edges are golden, and the tops bounce back when gently pressed, about 25 minutes.
Let cool in the pans for 15 minutes, then carefully transfer to a wire rack to cool completely. (If using only two pans, you can bake in 2 batches, washing a pan before baking the third layer).
Wrap in plastic and chill in the fridge until ready to assemble the cake.
To make the bourbon butterscotch:
In a medium saucepan set over medium heat, add the butter, brown sugar, corn syrup and salt. Heat, stirring frequently, until butter melts, sugar dissolves, and mixture is smooth, about 5 minutes.
Add heavy cream (mixture may sputter at first) and whisk until smooth. Increase heat to medium high and bring to a boil. Simmer for about 5 minutes until thickened slightly.
Remove from heat and stir in vanilla extract and bourbon. Let cool to room temperature.
To make the Swiss meringue buttercream:
Place the egg whites and sugar in the metal bowl of a stand mixer and set over a small pot of simmering water (the bowl should not touch the water). Heat, stirring occasionally, until mixture is 160°F or hot to the touch and sugar is dissolved.
Transfer bowl to stand mixer and beat on high speed with a whisk attachment to medium peaks, about 8 minutes. Reduce mixer speed to medium low and add butter a tablespoon at a time, letting it incorporate into the meringue for few moments before adding more.
Add vanilla extract and salt and beat on high for 1-2 minutes until smooth and creamy.
Add butterscotch all at once and mix until incorporated.
To assemble the cake:
If you'd like six cake layers, carefully cut each of the three layers in half (this step is optional).
Set one cake layer on plate or cake stand. Cover with 1/2 cup buttercream for 3 layers or 1/3 cup for 6 layers. Top with another cake layer. Repeat until cake is assembled.
Use an offset spatula to frost cake with buttercream.
Chill cake for 30 minutes.
Warm up remaining butterscotch for 20-30 seconds in the microwave so that it's pourable. Use a spoon to drizzle butterscotch over the top of the cake. Serve right away or chill until ready to serve. If chilled, let cake come to room temperature for 30 minutes before slicing. Store leftovers in the fridge for 3-5 days.
