In a large bowl, blend your cream cheese until smooth. Add sugar and beat until well incorporated. Add the vanilla, lemon juice and zest, yogurt, and egg. Blend until well combined. Scrap the sides of the mixing bowl with a rubber spatula to ensure all of the filling is incorporated and well mixed.
Next, evenly divide the filling into the muffin holes. The batter will not rise much, so you can fill them close to the top. Next, bake the mini cheesecakes in the preheated oven for about 18-20 minutes or until the mini cheesecakes are set on the edges and still a bit wobbly in the middle. Do not over bake.
Remove the mini cheesecakes from the oven and let cool on the counter for about 45 minutes. Then, place the mini cheesecakes in the refrigerator and let them and cool for at least 1.5 hours.
Once the cheesecakes are cooled, top them with homemade whipped cream and assorted berries or your favorite toppings. Then, enjoy!
