Ingredient Breakdown

Cream Cheese

Cream cheese provides:

• Rich flavor
• Creamy texture
• Cheesecake base
• Smooth consistency

Allowing it to soften before mixing creates the smoothest result.

Heavy Whipping Cream

Whipped cream gives the dessert:

• Airy texture
• Light consistency
• Rich flavor

Cold cream whips faster and develops better volume.

Powdered Low-Carb Sweetener

Powdered sweetener blends smoothly and prevents a grainy texture.

Popular choices include:

• Powdered erythritol
• Powdered monk fruit blend

Vanilla Extract

Vanilla creates the familiar birthday cake aroma and complements the cheesecake flavor.

Butter Extract

Although optional, butter extract provides the classic buttery cake batter flavor that makes this dessert unique.

Sugar-Free Sprinkles

Rainbow sprinkles add:

• Festive appearance
• Colorful presentation
• Light crunch

Choose sugar-free varieties if you want to keep the recipe lower in carbohydrates.

Kitchen Equipment

• Large mixing bowl
• Medium mixing bowl
• Electric hand mixer or stand mixer
• Silicone spatula
• Measuring cups
• Measuring spoons
• Dessert cups or serving glasses
• Rubber scraper

Step-by-Step Instructions

Step 1 – Prepare the Cream Cheese

Remove the cream cheese from the refrigerator about 30 minutes before beginning.

Softened cream cheese mixes much more smoothly than cold cream cheese.

Step 2 – Whip the Cream

Pour the cold heavy whipping cream into a chilled mixing bowl.

Using an electric mixer, beat on high speed for about 2–3 minutes until stiff peaks form.

Do not overwhip.

Place the whipped cream in the refrigerator while preparing the cheesecake mixture.

Step 3 – Make the Cheesecake Base

In another bowl combine:

• Softened cream cheese
• Powdered sweetener
• Sugar-free pudding mix
• Vanilla extract
• Butter extract

Beat until completely smooth.

Scrape down the sides of the bowl as needed.

The mixture should be creamy and free of lumps.

Step 4 – Fold Everything Together

Add the whipped cream to the cream cheese mixture.

Using a silicone spatula, gently fold the two mixtures together.

Continue folding until fully combined.

Avoid vigorous stirring because it removes the air from the whipped cream.

Step 5 – Add the Sprinkles

Fold most of the rainbow sprinkles into the cheesecake fluff.

Reserve a small amount for decorating the top.

Step 6 – Portion the Dessert

Divide the mixture evenly among six serving glasses or small dessert bowls.

A piping bag can also be used for an elegant presentation.

Step 7 – Garnish

Top each serving with:

• Reserved rainbow sprinkles
• Fresh berries (optional)
• Whipped cream (optional)

Step 8 – Chill

Cover the dessert cups.

Refrigerate for 30 minutes before serving.

Chilling improves both texture and flavor.
