Key Ingredients:

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Heavy Whipping Cream

Heavy whipping cream provides the airy, cloud-like structure of the dessert. Consequently, it whips up quickly to form stable, velvety peaks. Furthermore, full-fat coconut cream makes a great dairy-free swap.

Cream Cheese

Softened cream cheese adds rich tanginess and body to the mixture. Therefore, it prevents the whipped cream from deflating quickly. Make sure it stays at room temperature for smooth blending.

Fresh Blueberries

Fresh blueberries deliver bright color, juicy texture, and natural berry flavor. Next, gently fold them in to keep the fluff light. Furthermore, frozen berries work well when thawed and drained thoroughly.

Powdered Erythritol

Powdered erythritol provides smooth sweetness without adding unwanted net carbs. As a result, it dissolves easily into the fat base without any gritty texture.

Lemon Zest

Lemon zest adds a pop of bright citrus aroma to cut through the heavy cream. Consequently, it enhances the natural blueberry flavor remarkably well.

How to Make Keto Blueberry Fluff

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Beat softened cream cheese and powdered sweetener in a large bowl using a hand mixer on medium speed for 2 minutes until completely smooth and fluffy.
2. Pour cold heavy whipping cream into the mixture gradually while continuing to beat for 3 to 4 minutes until stiff, firm peaks form.
3. Gently fold fresh blueberries and bright lemon zest into the cream using a silicone spatula for 30 seconds until evenly distributed.
4. Chill the bowl in the refrigerator for at least 30 minutes at 38°F (3°C) until firm, cold, and ready to serve.

Pro Tip: Ensure your heavy whipping cream stays icy cold right up until mixing to achieve maximum volume and firm peaks.

Common Mistakes to Avoid:

• Using cold cream cheese: Cold cream cheese leaves small lumps throughout your smooth dessert fold.
• Over-whipping the heavy cream: Over-mixing turns your velvety whip into dense, sweet butter.
• Using wet berries: Excess water thins out the fluffy texture, making the mix runny.

Required Equipment:

• Hand mixer — blends cream cheese smoothly and whips heavy cream efficiently.
• Large mixing bowl — provides ample room for whipping without splashing liquid ingredients.
• Silicone spatula — folds delicate blueberries gently into whipped cream without crushing them.

Caleb's Recipe Tips

• Chill your bowl: Place your metal mixing bowl in the freezer for 10 minutes beforehand to whip cream faster.
• Use powdered sweetener: Granulated sweeteners leave a gritty texture, so choose finely powdered options instead.
• Mash a few berries: Lightly mash a quarter cup of blueberries before folding to yield a vibrant purple color.
• Add vanilla extract: A splash of pure vanilla extract enhances the berry notes significantly.

Storage Instructions

Store leftover blueberry fluff in an airtight container inside the refrigerator for up to 4 days. However, avoid freezing this dessert because freezing breaks the emulsion and ruins the delicate, fluffy texture. Serve chilled directly from the fridge.
