Ingredients Method

Ingredients

  

• For the crust: 2 cups Cinnamon Toast Crunch cereal, finely crushed
• 3 tablespoons light brown sugar
• 1 teaspoon ground cinnamon
• 4 tablespoons unsalted butter, melted (or light butter)
• Pinch of salt
• For the filling: 12 ounces reduced-fat cream cheese (Neufchâtel), softened to room temperature
• 1 3/4 cups plain nonfat Greek yogurt
• 2 large eggs, room temperature
• 1/2 cup vanilla whey or casein protein powder
• 1/2 cup granulated sweetener of choice (e.g., allulose, erythritol) or regular sugar
• 1/4 cup light brown sugar, packed
• 2 teaspoons pure vanilla extract
• 1 1/2 teaspoons ground cinnamon
• 1 tablespoon cornstarch
• 1/4 teaspoon fine salt
• Optional toppings: Light whipped topping or vanilla Greek yogurt
• Extra crushed Cinnamon Toast Crunch
• Cinnamon sugar dusting

Method

 

1. Prep the pan: Line the bottom of a 9-inch springform pan with parchment and lightly grease the sides. Preheat the oven to 325°F (163°C).
2. Make the crust: Stir crushed cereal, brown sugar, cinnamon, melted butter, and a pinch of salt until the mixture looks like wet sand. Press evenly into the pan, going slightly up the sides.
3. Parbake the crust: Bake for 8 minutes, then let it cool while you prepare the filling. Drop the oven to 300°F (149°C) to bake the cheesecake gently.
4. Beat the cream cheese: In a large bowl, beat the softened cream cheese until smooth, about 1 minute. Scrape the sides of the bowl.
5. Add yogurt and sweeteners: Mix in the Greek yogurt, granulated sweetener (or sugar), and brown sugar until creamy and well combined.
6. Add eggs and flavor: Beat in the eggs one at a time on low speed. Stir in vanilla, cinnamon, cornstarch, and salt. Finally, whisk in the protein powder just until no dry streaks remain. Do not overmix.
7. Fill the pan: Pour the batter over the cooled crust. Tap the pan gently on the counter to release any air bubbles.
8. Bake low and slow: Bake at 300°F for 45–55 minutes. The edges should be set and the center should have a slight wobble. Avoid opening the oven early.
9. Cool gradually: Turn off the oven, crack the door, and let the cheesecake sit inside for 30 minutes. This helps prevent cracks.
10. Chill completely: Move the pan to a rack to cool to room temperature, then cover and refrigerate for at least 6 hours, preferably overnight.
11. Finish and serve: Run a thin knife around the edge before releasing the springform. Add a light swirl of whipped topping or a spoonful of vanilla yogurt, then sprinkle with crushed cereal and a pinch of cinnamon sugar. Slice with a hot, clean knife for neat edges.

Why This Recipe Works

• High protein, real dessert vibes: Greek yogurt, reduced-fat cream cheese, and protein powder create a rich filling without relying on heavy cream.
• Flavor that tastes like the cereal: Cinnamon, a touch of brown sugar, and crushed Cinnamon Toast Crunch keep the taste familiar and nostalgic.
• Balanced sweetness: A mix of brown sugar and a zero-calorie sweetener keeps it sweet but not cloying. You can use all sugar if you prefer.
• No complicated water bath: This recipe bakes in a standard springform pan with a simple low-and-slow method to prevent cracks.
• Great make-ahead dessert: Cheesecake sets best overnight, so it’s perfect for prepping in advance.

How to Make It

1. Prep the pan: Line the bottom of a 9-inch springform pan with parchment and lightly grease the sides.

   Preheat the oven to 325°F (163°C).

2. Make the crust: Stir crushed cereal, brown sugar, cinnamon, melted butter, and a pinch of salt until the mixture looks like wet sand. Press evenly into the pan, going slightly up the sides.

Storage Instructions

• Refrigerator: Store covered for up to 5 days. Keep toppings off until serving so the cereal stays crunchy.
• Freezer: Freeze slices on a sheet pan until firm, then wrap individually and store for up to 2 months. Thaw overnight in the fridge.
• Make-ahead tip: Bake a day before you need it.

  Cheesecake tastes better after it sets for at least 12 hours.

Health Benefits

• High-quality protein: Greek yogurt, cream cheese, and protein powder team up to support muscle repair and keep you fuller longer.
• Lower fat than classic cheesecake: Using reduced-fat cream cheese and yogurt cuts saturated fat while keeping a creamy texture.
• Portion-friendly dessert: Because it’s rich in protein, a smaller slice feels more satisfying than a typical sugary treat.
• Flexible sweeteners: You can reduce added sugar by using allulose or erythritol without sacrificing taste.

Common Mistakes to Avoid

• Overmixing the batter: Too much air leads to cracking. Mix on low and stop when ingredients look smooth and combined.
• Skipping room-temperature ingredients: Cold cream cheese won’t blend well and can leave lumps.
• Baking too hot: High heat makes the top puff and crack. Keep it at 300°F and be patient.
• Rushing the cool-down: Sudden temperature changes can split the surface.

  Follow the slow cool and chill steps.

• Adding cereal toppings too early: They’ll get soggy. Add just before serving.

Recipe Variations

• Protein boost: Swap vanilla protein for cinnamon roll–flavored protein powder for an extra cinnamon punch. If your protein is very sweet, reduce added sweetener slightly.
• Gluten-free option: Use a gluten-free cinnamon cereal or a mix of gluten-free graham-style crumbs and cinnamon.
• No-bake version: Skip the eggs and cornstarch.

  Use the same crust but chill it. For the filling, beat 12 oz cream cheese, 1 1/2 cups Greek yogurt, 1/2 cup protein powder, 1/2 cup sweetener, vanilla, cinnamon, and a splash of milk until thick. Fold in 1 packet of bloomed gelatin (optional for firmness).

  Chill 6–8 hours.

• Swirl add-ins: Before baking, swirl 2–3 tablespoons of sugar-free cinnamon syrup or a light caramel sauce into the batter with a knife.
• Mini cheesecakes: Press crust into a lined muffin tin, add filling, and bake at 300°F for 16–20 minutes. Great for portion control.
• Apple cinnamon twist: Fold in 1/2 cup finely diced, sautéed apples (cooled) for a fall-inspired version.

FAQ

Can I make this without protein powder?

Yes. Replace the 1/2 cup protein powder with 1/4 cup additional Greek yogurt and 1 tablespoon more cornstarch.

The flavor will be slightly different, but the texture stays creamy.

What kind of protein powder works best?

Whey or a whey-casein blend works well because it blends smoothly. Plant-based powders can work, but start with 1/3 cup and add a splash of milk if the batter seems too thick.

How do I prevent cracks without a water bath?

Bake at a low temperature, don’t overmix, avoid opening the oven early, and follow the gradual cool-down. A thin line crack is normal and won’t affect taste.

Is Cinnamon Toast Crunch the only cereal that works?

No.

Any cinnamon-flavored crunchy cereal or cinnamon grahams will do. Adjust sugar slightly if your cereal is less sweet.

Can I use full-fat cream cheese?

Absolutely. Full-fat will be richer and slightly denser.

Keep all other measurements the same and monitor bake time near the 45-minute mark.

How do I know when it’s done?

The edges should look set, and the center should jiggle like Jell-O when you gently shake the pan. If it ripples like liquid, give it 5–10 more minutes.

What’s the best way to slice clean pieces?

Use a sharp knife dipped in hot water and wiped dry between cuts. Move slowly and avoid dragging crumbs across the top.
