- 1 ½ cups all-purpose flour
- ½ teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon fine sea salt
- ½ teaspoon ground cinnamon, divided
- 1 cup softened butter, divided
- ¾ cup granulated sugar
- ½ cup buttermilk
- ¼ cup vegetable oil
- 2 eggs
- 3 teaspoons vanilla extract, divided
- 1 ⅓ cups whole milk ricotta, divided
- ¼ cup heavy whipping cream
- 4 ¼ cups powdered sugar, divided
- ½ tablespoon lemon zest
- ¼ cup mini chocolate chips, plus more for garnish
- Preheat the oven to 350 F, line a 12-count muffin pan with muffin liners, and place a medium or large bowl in the fridge to chill.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and ¼ teaspoon cinnamon. Set aside.
- Melt ½ cup of the butter. In a large bowl, whisk together the melted butter, granulated sugar, buttermilk, vegetable oil, eggs, and 1 teaspoon vanilla extract.
- Add the dry ingredients to the wet ingredients and whisk until combined, being careful not to overmix.
- Divide the batter evenly into the prepared muffin pan, filling each well about ⅔ full. Bake in the preheated oven for 18-20 minutes until a toothpick inserted into the center comes out clean. Let the cupcakes cool completely.
- Meanwhile, place the ricotta in a fine mesh strainer over a bowl and let drain for at least 30 minutes.
- Make the cannoli cream filling. Add the heavy cream to the chilled empty bowl and beat at a high speed until stiff peaks form. Add in ¼ cup powdered sugar and beat until combined.
- In a separate bowl, combine 1 cup drained ricotta, 1 teaspoon vanilla extract, lemon zest, and the remaining ¼ teaspoon cinnamon. Gently fold in the whipped cream and chocolate chips until combined.
- Use a spoon or cupcake corer to cut out a circle in the center of each cooled cupcake, about 1 inch deep. Spoon or pipe the cannoli cream into each cupcake until each hole is filled with cream.
- To make the ricotta buttercream frosting, add the remaining ½ cup softened butter and ⅓ cup ricotta to a large bowl and beat on high with an electric mixer until combined and fluffy.
- Add in the remaining 4 cups powdered sugar and 1 teaspoon vanilla extract and beat on low until the frosting is smooth.
- Pipe frosting onto each of the filled cupcakes. Top with some additional mini chocolate chips, if desired, and serve.
