That rich, nutty flavor instantly transports me back to happy childhood days, and this Keto Peanut Butter Dessert captures all that comforting charm without the sugar. It’s a dreamy, creamy no-bake delight that feels incredibly indulgent, yet fits beautifully into a keto lifestyle.

I remember my grandmother, bless her heart, always had a little something sweet tucked away. She’d say, “Sara, a day without a little treat is a day half-lived!” While her treats were often baked, she taught me the joy of simple ingredients and how a little patience can create something truly special, a lesson I carried into experimenting with healthier options like this.

This recipe is wonderfully straightforward, making it perfect for busy weeknights or when you need an impressive dish for unexpected guests. It’s a delightful way to satisfy those sweet cravings, and my top tip for any no-bake wonder is to give it ample chilling time—that’s where the magic truly happens, allowing all those lovely flavors to meld.

Prep Time 15 minutes
Total Time 15 minutes
Servings: 4 bowls
Course: Dessert, Soup
Cuisine: American

Ingredients
  

For the Peanut Butter Soup
  • 1/2 cup creamy peanut butter unsweetened, no sugar added
  • 1 can full-fat coconut milk 13.5 oz, unsweetened, or 1.5 cups heavy cream
  • 1/4 cup erythritol or monk fruit sweetener blend adjust to taste
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 1/4 cup unsweetened almond milk or water, for thinning, adjust as needed
Optional Garnish
  • 2 tbsp sugar-free chocolate chips
  • 1/2 tsp coconut oil for melting chocolate

Equipment

  • High-speed blender
  • Whisk
  • Large Mixing Bowl
  • Small Saucepan (optional)
  • Serving bowls

Method
 

Prepare the Soup Base
  1. In a high-speed blender, combine the unsweetened creamy peanut butter, full-fat coconut milk (or heavy cream), erythritol or monk fruit sweetener, vanilla extract, and salt.
  2. Blend on high speed until the mixture is completely smooth and creamy. Stop and scrape down the sides of the blender with a spatula as needed to ensure all ingredients are well incorporated.
  3. Taste the mixture and adjust sweetener if desired. If the soup is too thick for your preference, add the unsweetened almond milk (or water) one tablespoon at a time, blending briefly after each addition, until the desired pourable consistency is reached.
Chill and Garnish
  1. Pour the blended soup into a large bowl or pitcher. Cover it tightly and refrigerate for at least 2-3 hours, or preferably overnight, to allow the soup to chill thoroughly and for the flavors to deepen and meld. Chilling is essential for the best texture and taste.
  2. If using the optional chocolate garnish, gently melt the sugar-free chocolate chips with the coconut oil in a small microwave-safe bowl in 15-second intervals, stirring after each, or in a small saucepan over very low heat until smooth. Let the melted chocolate cool slightly so it’s not too hot when drizzling.
  3. Before serving, give the chilled soup a gentle whisk to ensure it’s well combined. Divide evenly into four serving bowls. Drizzle with the melted chocolate, if desired, and serve immediately.

Notes

For an extra rich soup, you can add 2 ounces of softened cream cheese to the blender with the other ingredients. Ensure your peanut butter is truly unsweetened and contains no added oils or sugars for the best keto results. Store leftovers in an airtight container in the refrigerator for up to 3-4 days.

Pro Tips for Making This Keto Peanut Butter Dessert

Getting that perfect, creamy consistency for your Keto Peanut Butter Dessert is key to its dreaminess.


  • Blending for Bliss: Ensure all your ingredients for the soup base are at room temperature before blending. This helps them combine more smoothly, preventing any lumps and giving you that wonderfully silky texture. A powerful blender or food processor will make this step effortless.



  • My Secret Trick: I always make sure to chill this dessert for at least 4 hours, or even better, overnight. That extended chilling time isn’t just for firmness; it allows the flavors to truly marry and deepen, making every spoonful an even more luxurious experience.



  • Sweetness to Your Liking: Taste your mixture before chilling and adjust the sweetener if needed. Different brands of erythritol or monk fruit blends can vary in potency, so a quick taste test ensures your dessert is perfectly tailored to your palate.



  • Perfect Portions: If you’re aiming for a “bar-like” presentation for this thick, creamy dessert, consider pouring it into a lined square dish for chilling. Once firm, you can easily cut it into neat squares before garnishing.


Fun Variations for Keto Peanut Butter Dessert

One of the joys of baking is getting creative, and this Keto Peanut Butter Dessert is wonderfully adaptable. Here are a few ways to make it your own!

Chocolate Swirl Sensation

For all the chocoholics out there, like my dear friend Sarah who absolutely adores chocolate, melt some sugar-free chocolate chips with a touch of coconut oil and swirl it into the base before chilling. The marbling effect is beautiful, and the chocolate-peanut butter combination is simply divine.

Nutty Crunch Topping

If you miss a bit of crunch, consider sprinkling some chopped keto-friendly nuts like pecans or walnuts on top before the final chill. This adds a lovely textural contrast to the smooth, creamy Keto Peanut Butter Dessert.

Berry Burst Brightness

A touch of fruit can really lighten things up! My sister always asks me to serve her portion with a few fresh raspberries or a light drizzle of sugar-free raspberry sauce. The tartness is a wonderful counterpoint to the richness.

What to Serve With Keto Peanut Butter Dessert

For a simple and quick serving idea, a sprinkle of extra sugar-free chocolate chips over the top adds a delightful burst of flavor and a pretty finish. In the cooler months, my mom always insists on pairing it with a steaming mug of her homemade sugar-free hot cocoa – it’s pure comfort! Alternatively, a brisk cup of black coffee or unsweetened almond milk can provide a lovely balance to its richness, making for a truly satisfying end to any meal.
