Pre-heat oven to 350F (180C). Grease and flour or spray a 9½-10 inch bundt pan (24cm).
In a medium bowl whisk together the flour, baking powder and salt.
In the bowl of a stand mixer with the flat beaters or a large bowl with beaters beat together the eggs, yolk and sugar for 2 minutes, add the melted butter and vanilla, beat to combine. Beat in the ricotta, add the zest and milk, beat to combine.
Add the dry ingredients and combine. Transfer the batter to the prepared pan and bake for approximately 50-55 minutes, test for doneness with a toothpick, if it's dry or a few crumbs attached it's done. Let cool in pan then move to a serving plate. Dust with powdered sugar before serving. Enjoy!
Notes
For room temperature remove the ingredients 45-60 minutes from the fridge before using.To make homemade cake/pastry flour - for every cup of all purpose flour, remove two tablespoons and replace with two tablespoons of corn starch. Be sure to sift the flour and cornstarch together a couple of times, this way it is sure to be properly combined and lump free. Cake flour in cakes will give you a very tender texture and fine crumb, it will also help the cake to rise.Instead of making a lemon ricotta bundt cake, prepare batter as directed and divide the batter into two round 8 inch/20cm cake pans that have been lined with parchment paper and greased.Since this cake includes ricotta cheese, it should be stored in the refrigerator. Store in an airtight container for 5-7 days and bring to room temperature before serving or serve chilled! To freeze, cool the cake completely then wrap in plastic wrap, then foil to prevent freezer burn. Store it in an airtight container or freezer bag for 2-3 months.
