Ingredients for Peanut Butter Fluff
To make this keto-friendly, creamy dessert, you’ll need the following ingredients:
- 1/2 cup heavy whipping cream – Provides a light and airy texture when whipped, balancing the creaminess of the peanut butter.
- 4 ounces cream cheese, softened – Softened cream cheese adds a smooth, velvety base to the dessert, making it extra decadent.
- 3 tablespoons all-natural peanut butter – Choose a natural, unsweetened peanut butter for best results, which adds a rich nutty flavor.
- 1/4 cup keto-friendly sweetener (such as Lakanto) – A low-carb sweetener like erythritol, monk fruit, or stevia will add sweetness without impacting your macros.
- 1/2 teaspoon vanilla extract – Enhances the flavor profile with a subtle warmth.
- Lily’s chocolate chips – These sugar-free chocolate chips add a delightful topping and a bit of crunch.
Instructions for Making Peanut Butter Fluff
Step 1: Prep the Heavy Whipping Cream
Begin by pouring the heavy whipping cream into a medium mixing bowl. Place the bowl in the refrigerator while preparing the other ingredients. Chilling the cream beforehand makes it easier to whip into soft peaks and helps it achieve a stable, fluffy texture.
Step 2: Blend Cream Cheese and Peanut Butter
In a large mixing bowl, combine the softened cream cheese, peanut butter, sweetener, and vanilla extract. Using a hand mixer or stand mixer, blend until smooth. Be sure to scrape the sides of the bowl occasionally to ensure all ingredients are fully incorporated. The mixture should be creamy and free of lumps for the best results.
Step 3: Whip the Heavy Cream
Remove the heavy whipping cream from the refrigerator. Use a hand mixer or stand mixer to whip the cream on medium-high speed until soft peaks form, which should take about 2-3 minutes. You’ll know it’s ready when the cream holds its shape but still has a gentle, soft fold.
Step 4: Combine the Mixtures
Gently fold the whipped cream into the peanut butter mixture, using a spatula to blend carefully. Folding helps retain the airiness of the whipped cream, creating a fluffy, mousse-like texture. Continue to fold until you achieve a well-mixed, smooth consistency, but be careful not to over-mix, as this can cause the fluff to become too dense.
Step 5: Garnish with Chocolate Chips
Spoon the Peanut Butter Fluff into small dessert bowls or glasses, then sprinkle Lily’s chocolate chips on top. These sugar-free chocolate chips add a touch of chocolatey flavor and a bit of texture, perfectly complementing the creamy fluff.
Step 6: Serve and Enjoy
Serve the fluff immediately for a soft and creamy texture, or refrigerate for an hour or two if you prefer a firmer consistency. Either way, this dessert is deliciously satisfying and can be enjoyed at any time of the day.
Tips for Making the Best Peanut Butter Fluff
- Chill the Mixing Bowl and Whisk – Cold tools help the heavy cream whip faster and maintain a stable consistency. Consider chilling your mixing bowl and whisk attachments for a few minutes before whipping the cream.
- Choose the Right Peanut Butter – For the creamiest texture, use a smooth, natural peanut butter without added sugars or oils. This will keep the recipe keto-friendly while providing a rich, nutty flavor.
- Sweeten to Taste – Depending on your taste preferences, you can adjust the amount of sweetener. Some keto-friendly sweeteners like monk fruit or erythritol can taste less sweet than sugar, so feel free to increase or reduce the amount slightly as needed.
- Make It in Advance – Peanut Butter Fluff can be made ahead and stored in the refrigerator for up to 3 days. The flavor will deepen as it chills, making it even more delicious.
- Experiment with Toppings – Try adding a sprinkle of sea salt for a sweet-salty twist, or top with chopped nuts, sugar-free chocolate shavings, or even a dash of cinnamon.
