Preheat oven to 300 degrees F and line a cupcake pan with paper cupcake liners.
Beat the Neufchatel (or cream cheese) on low speed or by hand until smooth.
Add the yogurt and vanilla, and mix well.
Add eggs one at a time, mixing to combine after adding each.
Add the whey powder and stevia, and mix well.
Spoon batter into the cupcake liners.
Place the cupcake tin in a larger pan (a ½ sheet pan works well) for the water bath. Also get a few cups of hot water ready.
Place the pans in the oven, and pour the hot water into the sheet pan. Close the oven door.
Bake for 30-40 minutes, just until the centers are set. (This range accounts for ovens that don’t hold 300 very well.)
Let the mini cheesecakes cool in the pan for ~ 10 minutes, then have them cool completely on a wire rack. Refrigerate the cheesecakes in an airtight container for 2-3 hours until completely chilled and set.
Notes
Ingredient SubstitutionsNeufchatel Cheese: Substitute with full-fat cream cheese if Neufchatel is hard to find.Stevia Powder: Use a granulated sweetener like erythritol or coconut sugar, or a natural liquid sweetener like agave or maple syrup, if preferred. (Coconut sugar and agave are low glycemic, which can be a better choice than refined sugar for most people.)
Vanilla Extract: Add a splash of lemon juice or almond extract for a flavor twist.
Recipe VariationsChocolate Chips: Sprinkle sugar free mini chocolate chips on top before baking for a fun twist.Lemon Zest: Add lemon zest and a splash of lemon juice for a light lemon flavor.
Peanut Butter: Swirl a teaspoon of warmed peanut butter into each cheesecake before baking.Graham Cracker Crust: Add a graham cracker crust by mixing graham cracker crumbs with melted butter and pressing them into the muffin liners before adding the filling. (Gluten free graham crackers work just as well here.)
Storage InfoStore mini protein cheesecakes in an airtight container in the refrigerator for up to 5 days. For longer storage, wrap each mini cheesecake in plastic wrap and store in an airtight container in the freezer for up to 3 months.
