Creating the Easy Cannoli Cake Recipe with Chocolate Ganache is a simple process if you follow these steps carefully:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

2. Prepare the Cake Batter: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, and salt. In another bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until well combined. Gradually add the wet ingredients to the dry ingredients, stirring until smooth.

3. Bake the Cakes: Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

4. Cool the Cakes: Remove the cakes from the oven and allow them to cool in the pans for about 10 minutes. Then, carefully transfer them to wire racks to cool completely.

5. Make the Cannoli Filling: In a mixing bowl, combine the ricotta cheese, powdered sugar, vanilla extract, and cinnamon (if using). Mix until smooth and creamy. Gently fold in the mini chocolate chips.

6. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving platter. Spread the cannoli filling evenly over the top. Place the second cake layer on top of the filling.

7. Prepare the Chocolate Ganache: In a small saucepan, heat the heavy cream over medium heat until it begins to simmer. Remove from heat and add the chocolate chips. Stir until the chocolate is melted and the mixture is smooth. Let it cool slightly before pouring it over the top of the assembled cake.

8. Finish with Ganache: Pour the chocolate ganache over the top of the cake, allowing it to drip down the sides for a beautiful finish.
