15 - 1 and 1/2 cups heavy cream
16 - 3 and 1/2 Tablespoons light corn syrup
17 - 1 teaspoon vanilla extract
18 - 16 Tablespoons unsalted butter, at room temperature
19 - 1/8 teaspoon fine sea salt

# Instructions:

01 - Preheat oven to 350°F. Spray two 9-inch round baking pans with non-stick spray. Line bottoms with parchment paper rounds and spray again
02 - In a large bowl, sift together flour, cocoa powder, baking soda, baking powder, and salt; set aside
03 - Beat butter until smooth, about 1 minute. Gradually add both sugars and beat until light and fluffy, about 4 minutes
04 - Add eggs and egg yolk one at a time, beating well after each addition. Add vanilla extract and beat until combined
05 - In a measuring cup, combine oil and sour cream
06 - On lowest speed, add flour mixture in three additions, alternating with sour cream mixture in two additions, mixing until just combined
07 - Pour in hot coffee, let sit 30 seconds, then gently stir with rubber spatula until evenly combined
08 - Divide batter between pans (about 850 grams per pan) and smooth tops. Bake for 38-45 minutes until toothpick inserted comes out clean or with few moist crumbs
09 - Cool cakes in pans on wire rack for 20 minutes, then invert onto rack to cool completely, about 1 hour
10 - Finely chop chocolate and place in bowl of stand mixer with whisk attachment
11 - Heat cream and corn syrup until just short of boiling. Pour over chopped chocolate and let sit 2 minutes
12 - Gently stir until chocolate is melted and mixture is smooth and glossy. Stir in vanilla
13 - Beat in butter 1 tablespoon at a time, ensuring each addition is incorporated before adding more. Beat in salt
14 - Refrigerate frosting, loosely covered, for about 1 hour until firm enough to spread
15 - Trim domed tops of cakes, then slice each cake in half horizontally to create 4 even layers. Save trimmings for decoration
16 - Place one layer on cake stand. Spread 1/2 cup frosting on top, add next layer, and repeat until all layers are stacked
17 - Spread remaining frosting over top and sides of cake
18 - Crumble reserved cake scraps and gently press around sides of cake
19 - Allow cake to set for 20 minutes before slicing. Store in refrigerator up to 5 days, bringing to room temperature before serving

# Notes:

01 - The cake is intensely rich and moist yet dense in texture
02 - Frosting can be made up to 24 hours ahead and stored in refrigerator
03 - Coffee enhances the chocolate flavor without making the cake taste like coffee
