Ingredients Method

Ingredients
  

  • Cream cheese: 16 oz (two 8-oz blocks), softened to room temperature.
  • Plain Greek yogurt: 1 cup (2% or 0% both work; 2% gives a creamier texture).
  • Natural peanut butter: 1/2 cup, well-stirred (use a no-sugar-added brand for best control).
  • Whey or casein protein powder: 1/2 cup vanilla or unflavored. Whey keeps it lighter; casein yields a denser, custard-like texture.
  • Eggs: 3 large, at room temperature.
  • Sweetener: 1/3–1/2 cup granulated sugar or a zero-calorie sweetener like allulose or erythritol. Adjust to taste.
  • Vanilla extract: 1 teaspoon.
  • Salt: 1/4 teaspoon to balance the sweetness.
  • Milk: 2–4 tablespoons (dairy or unsweetened almond milk) to loosen the batter if needed.
  • Optional add-ins: 2 tablespoons mini chocolate chips or chopped peanuts for texture.
  • For the crust (optional): 1 1/2 cups graham cracker crumbs (or almond flour for gluten-free)
  • 3 tablespoons melted butter (or coconut oil)
  • 1 tablespoon sweetener
  • Pinch of salt
  • Pan: 8- or 9-inch springform pan (or a 9-inch deep pie dish).

Method
 

  1. Bring ingredients to room temp. Set out cream cheese, eggs, and yogurt for at least 30–45 minutes. This helps the batter blend smoothly and prevents lumps.
  2. Prep the pan and oven. Heat the oven to 325°F (163°C). Line the bottom of a springform pan with parchment and lightly grease the sides. Wrap the outside with foil if you plan to use a water bath.
  3. Make the crust (optional). Stir crumbs, melted butter, sweetener, and salt until the texture resembles wet sand. Press firmly into the pan in an even layer. Bake 8–10 minutes, then cool while you mix the filling.
  4. Beat the cream cheese. In a large bowl, beat softened cream cheese on medium speed for 1–2 minutes until very smooth. Scrape the bowl to avoid lumps.
  5. Add peanut butter and sweetener. Mix in peanut butter, sweetener, vanilla, and salt. Beat until fully combined and creamy.
  6. Blend in Greek yogurt and protein powder. Add yogurt and protein powder. Start on low speed, then move to medium until the batter is silky. If it feels too thick, mix in 2–4 tablespoons of milk, 1 tablespoon at a time, just to loosen.
  7. Add eggs last. Beat in eggs one at a time on low speed until just combined. Avoid overmixing to keep the texture tender and prevent cracks.
  8. Pour and smooth. Pour the batter over the crust (or into a prepared pan without crust). Tap the pan gently on the counter to pop air bubbles. Sprinkle any optional add-ins on top or fold them in.
  9. Choose your bake method. Water bath (most crack-proof): Place the pan in a larger roasting pan. Pour hot water around it to reach halfway up the sides. Bake 40–55 minutes at 325°F until the edges are set and the center has a slight wobble.
  10. No water bath: Bake 45–60 minutes at 300–325°F. If the top browns too fast, tent lightly with foil.
  11. Cool gradually. Turn off the oven, crack the door, and let the cheesecake sit for 30 minutes. Then remove and cool to room temperature. This slow cool helps avoid surface cracks.
  12. Chill before slicing. Cover and refrigerate at least 6 hours, ideally overnight. The flavor deepens and the texture firms up.
  13. Slice and serve. Warm a sharp knife under hot water and wipe between cuts for clean slices. Top with a drizzle of melted peanut butter, Greek yogurt “whip,” shaved dark chocolate, or crushed peanuts.
