# Steps to Follow:
01 - Preheat oven to 350°F. Grease and line two 9-inch round cake pans with parchment paper.
02 - In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt until well combined.
03 - In another bowl, whisk olive oil, milk, eggs, and vanilla extract until smooth. Pour wet ingredients into dry mixture and stir until just combined.
04 - Slowly add hot brewed coffee while whisking continuously until batter is smooth and thin.
05 - Divide batter evenly between prepared pans. Bake 35 to 40 minutes, or until a toothpick inserted in the center comes out mostly clean.
06 - Cool cakes in pans for 10 minutes, then turn out onto wire racks and cool completely.
07 - Place chopped chocolate in a heatproof bowl. Heat heavy cream in a saucepan until just simmering, then pour over chocolate. Let sit 2 minutes. Add butter and stir until smooth and glossy. Cool while stirring occasionally until thickened to spreading consistency.
08 - Line a baking sheet with parchment paper. In a small saucepan, heat sugar over medium heat, swirling until melted and amber in color. Remove from heat, stir in hazelnuts and salt, then quickly spread onto prepared sheet. Cool completely, then break into shards or chop coarsely.
09 - Place one cake layer on a serving plate. Spread with one-third of the ganache. Top with second cake layer and cover top and sides with remaining ganache. Decorate generously with hazelnut praline shards.
