This High-Protein Birthday Cake Cheesecake is my cottage cheese cheesecake turned into birthday cake. The filling combines low-fat cream cheese, nonfat cottage cheese, eggs, and casein protein powder with cake batter flavoring and rainbow sprinkles.
Everything except the sprinkles goes into the food processor. Once the batter is completely smooth, fold the sprinkles in by hand and bake it low at 325°F for 60–65 minutes.
The most important part is not overbaking it. Pull it when the edges are set but the middle still has a wobble, then turn the oven off and leave the cheesecake inside for another 20 minutes with the door cracked open. That gradual cooling gives the center time to finish setting without drying out.

Why You’ll Love This Recipe
- It actually tastes like birthday cake. Cake batter flavoring and rainbow sprinkles give it more than plain vanilla flavor.
- The cottage cheese blends completely into the filling. Once smooth, there are no curds scattered through the cheesecake.
- Two scoops of casein add more protein. This version uses casein rather than relying only on dairy and eggs.
- No crust or water bath required. The cheesecake goes straight into a lined springform pan and uses a gradual cooling period.
- Easy batter. The food processor does almost all of the work.
Ingredients
- 2 (8-ounce) blocks low-fat cream cheese, softened
- 2 cups nonfat cottage cheese
- 4 large eggs
- 2 scoops casein protein powder
- 1 cup granulated cup-for-cup sugar alternative
- 2 teaspoons cake batter flavoring
- ½ teaspoon salt
- About ⅓ cup rainbow sprinkles
- Cooking spray, for the pan
Ingredient Notes
Low-Fat Cream Cheese: This keeps the cheesecake tasting like cheesecake instead of turning it into a baked cottage cheese dessert. Let it soften before blending.
Nonfat Cottage Cheese: This adds dairy and protein without another two blocks of cream cheese. Blend until no curds remain.
Casein Protein Powder: This cheesecake was tested with two scoops of casein. Casein thickens differently from whey, so straight whey may not bake the same way.
Cake Batter Flavoring: This gives the filling its recognizable birthday-cake flavor. Plain vanilla will not taste quite the same.
Sugar Alternative: Use a granulated cup-for-cup replacement, not a concentrated sweetener measured at one full cup.
Rainbow Sprinkles: Fold these in after blending so they stay visible instead of smearing through the batter.
Why This Birthday Cake Protein Cheesecake Works
The cottage cheese is fully blended with the cream cheese before baking, creating a smooth cheesecake batter. The casein goes directly into the moisture-rich dairy and egg base, and the lower 325°F oven temperature keeps the cheesecake from baking too aggressively.
The cheesecake is ready to start cooling when the outside looks set but the center still moves when the pan is gently shaken. That wobble is intentional; waiting until the middle is completely firm risks overbaking.
Equipment
- 9-Inch Springform Pan: The removable side makes it easier to release a chilled cheesecake.
- Food Processor: The easiest way to get the cottage cheese completely smooth.
- Silicone Spatula: Useful for scraping the food processor and folding in the sprinkles.
You’ll also need parchment paper for the bottom of the pan.

High-Protein Birthday Cake Cheesecake Step-by-Step Instructions
- Prep the pan: Preheat the oven to 325°F. Line the bottom of a 9-inch springform pan with parchment paper and lightly spray the sides with cooking spray.
- Add the cheesecake ingredients: Add the softened cream cheese, cottage cheese, eggs, casein protein powder, sugar alternative, cake batter flavoring, and salt to a food processor.
- Blend until completely smooth: Process until no cottage cheese curds or dry protein powder remain, scraping the sides and bottom as needed.
- Fold in the sprinkles: Remove the blade and gently fold in about ⅓ cup rainbow sprinkles with a spatula. Do not blend them.
- Fill the springform pan: Pour the batter into the prepared pan and smooth the top.
- Bake for 60–65 minutes: Bake at 325°F until the edges are set and the middle is still wobbly when the pan is gently moved.
- Cool slowly in the oven: Turn the oven off, crack the door slightly, and leave the cheesecake inside for 20 minutes.
- Cool completely: Remove the cheesecake from the oven and let it cool completely.
- Chill before slicing: Refrigerate until cold and firm, then release the springform pan and slice.
Expert Tips
- Blend longer than you think you need to. Visible cottage cheese curds can remain noticeable once baked.
- Fold the sprinkles in last. They only need enough mixing to distribute them.
- Watch the cheesecake, not just the clock. Set edges and a wobbly center matter more than one exact minute.
- Don’t bake out the wobble. The center continues to set during the 20-minute oven cool and as it chills.
- Chill before cutting. Cold cheesecake slices more cleanly.
Substitutions
Suggested substitutions: Results can vary by brand or product, and small adjustments to moisture, timing, or texture may be needed.
- Casein protein powder: Casein is the tested protein powder. Straight whey has not been tested.
- Sugar alternative: Another granulated cup-for-cup substitute should be the closest swap.
- Rainbow sprinkles: Similar baking sprinkles in different colors can change the look.
- Low-fat cream cheese and nonfat cottage cheese: Other fat levels may change texture and nutrition.
Frequently Asked Questions
Can you taste the cottage cheese?
The goal is for it to disappear into the cheesecake. Blend until the filling is completely smooth.
Can I use whey protein instead of casein?
This recipe was tested with casein. Whey behaves differently when baked, so the tested version is the safest starting point.
How do I know when the cheesecake is done?
The edges should look set and the middle should still wobble without looking like raw liquid batter.
Do I need a water bath?
No. This recipe bakes directly in the springform pan at 325°F and uses a gradual oven-cooling step.
Can I use vanilla instead of cake batter flavoring?
You could make a vanilla cheesecake, but it would not have the same birthday-cake flavor.
Why did my cheesecake crack?
Overbaking or cooling too aggressively can make cracking more likely. Pull it while the center still wobbles and use the 20-minute oven cool.
Storage
Keep the cheesecake refrigerated once cooled. Store slices covered or in an airtight container. Freezing this specific version has not been tested, so the sprinkle color and texture may change after thawing. Serve chilled.
