# What You'll Need:

→ Cake

01 - 1 3/4 cups all-purpose flour
02 - 3/4 cup unsweetened cocoa powder
03 - 2 cups granulated sugar
04 - 1 1/2 teaspoons baking powder
05 - 1/2 teaspoon baking soda
06 - 1/2 teaspoon fine sea salt
07 - 3/4 cup extra-virgin olive oil
08 - 1 cup whole milk, room temperature
09 - 3 large eggs, room temperature
10 - 2 teaspoons vanilla extract
11 - 1 cup hot brewed coffee

→ Ganache

12 - 12 oz bittersweet chocolate, finely chopped
13 - 1 cup heavy cream
14 - 2 tablespoons unsalted butter

→ Hazelnut Praline

15 - 1 cup toasted hazelnuts, skins rubbed off
16 - 3/4 cup granulated sugar
17 - Pinch of sea salt

# Method:

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 thoroughly combined.
03 - In another bowl, whisk olive oil, milk, eggs, and vanilla until smooth. Pour wet ingredients into dry and mix until just combined.
04 - Slowly add hot coffee, whisking until batter is smooth and uniform. The batter will be 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 to cool completely before assembling.
07 - Place chocolate in a heatproof bowl. Heat cream in a small saucepan until just simmering, then pour over chocolate. Let sit 2 minutes. Add butter and stir until smooth and glossy. Let cool, stirring occasionally, until thickened to spreading consistency.
08 - Line a baking sheet with parchment. 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 a third of the ganache. Top with the second cake layer and cover top and sides with remaining ganache. Decorate generously with hazelnut praline shards.

# Expert Advice:

01 -
  • The olive oil keeps the cake moist for days, unlike butter cakes that dry out
  • This looks like a bakery showstopper but uses techniques anyone can master
  • The hazelnut praline adds this incredible crunch that makes every bite exciting
02 -
  • The ganache needs time to thicken to spreading consistency, so make it first and let it cool while you bake the cakes
  • Hot coffee is non negotiable here, it properly blooms the cocoa powder in a way that room temperature liquid cannot achieve
03 -
  • Rotate the cake pans halfway through baking for even rising, especially if your oven has hot spots like mine does
  • Tap the pans gently on the counter before baking to release any large air bubbles for a more even crumb
