Phase 1: Bake the Rich Chocolate Cake Layers
Preheat & Prep: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch or 9-inch round cake pans. Line the bottoms with parchment paper for an easy release.
Dry Ingredients Whisk: In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until thoroughly combined. Make a well in the center.
Wet Ingredients Mix: In a separate bowl, whisk together eggs, buttermilk, oil, and vanilla extract.
Combine & Conquer: Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix! Slowly pour in the hot water/coffee, mixing on low speed until the batter is smooth and fairly thin. It will look like a river of molten chocolate!
Divide & Bake: Divide the glorious batter evenly between your prepared pans. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
Cool It: Let the cakes cool in their pans for 10-15 minutes before inverting them onto a wire rack to cool completely. Wrap well once cooled if not assembling immediately.
PH 2: Create the Cool Mint Cheesecake Layer
Oven Temp Adjustment: Reduce oven temperature to 325°F (160°C). Prepare an 8-inch or 9-inch springform pan by lightly greasing it.
Cream Cheese Beatdown: In a large bowl, beat the softened cream cheese with an electric mixer on medium speed until completely smooth and lump-free – we want satin!
Sweeten the Deal: Gradually add the sugar, beating until smooth.
Eggcelent Addition: Add eggs one at a time, beating on low speed after each addition until just combined. Don’t overbeat here; it incorporates too much air.
Minty Fresh & Tangy: Stir in the sour cream, peppermint extract, and green food coloring (if using) until just blended. Gently fold in the mini chocolate chips or chopped mint candies.
Bake with Care: Pour the ethereal mint cheesecake batter into the prepared springform pan. Bake for 45-55 minutes, or until the edges are set and the center is just barely jiggly.
Slow Cool for Perfection: Turn off the oven and let the cheesecake cool in the oven with the door slightly ajar for 1 hour. This prevents cracking. Then, remove and let it cool completely on a wire rack. Once cool, cover with plastic wrap and refrigerate for at least 6 hours, or preferably overnight, until thoroughly chilled and firm. This is key for the perfect Mint Chocolate Cheesecake Cake texture.
Phase 3: Assemble Your Dream Cake & Drench in Ganache
Level Up: If your chocolate cake layers have domed tops, carefully level them with a serrated knife.
First Layer of Bliss: Place one chocolate cake layer on your serving plate or cake stand.
Cheesecake Crown: Carefully remove the mint cheesecake from the springform pan. If it’s slightly larger than your cake layer, you can gently trim it with a sharp knife (chill it well first!). Place the chilled cheesecake layer on top of the first chocolate cake layer.
Top it Off: Place the second chocolate cake layer on top of the cheesecake. Gently press down.
Ganache Glory:
Place chopped chocolate in a heatproof bowl.
Heat heavy cream in a small saucepan over medium heat until it just begins to simmer (don’t boil!).
Pour the hot cream over the chopped chocolate. Let it sit for 5 minutes to melt the chocolate.
Whisk gently until the ganache is smooth, glossy, and utterly irresistible. Let it cool slightly, until it’s thick but still pourable.
Drizzle & Drench: Pour the luscious ganache over the top of your assembled Mint Chocolate Cheesecake Cake, allowing it to drip seductively down the sides. You can spread it with an offset spatula for a smoother finish if desired.
Final Chill: Refrigerate the cake for at least 1-2 hours to allow the ganache to set before slicing and serving.
