Making the Easy Cannoli Cake Recipe with Chocolate Ganache can be broken down into several simple steps:

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

2. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, and salt until well combined.

3. Combine Wet Ingredients: In another bowl, mix the milk, vegetable oil, eggs, and vanilla extract. Whisk until smooth.

4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until the batter is smooth and free of lumps.

5. Bake the Cakes: Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.

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

7. Prepare the Cannoli Filling: In a medium bowl, combine the ricotta cheese, powdered sugar, vanilla extract, cinnamon, and mini chocolate chips. Mix until smooth and well incorporated.

8. Make the Chocolate Ganache: In a small saucepan over medium heat, bring the heavy cream to a simmer. Remove from heat and add the chopped chocolate. Let sit for a minute, then stir until smooth and glossy.

9. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving platter. Spread a generous layer of the cannoli filling on top. Repeat with the second layer and add the third layer on top.

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

11. Garnish: Sprinkle mini chocolate chips on top and dust with powdered sugar if desired.

12. Chill: Allow the cake to chill in the refrigerator for at least 30 minutes before serving to set the ganache.
