Ingredients with Measurements

• 1 1/3 cups heavy cream
• 2/3 cup unsweetened almond milk
• 1/3 cup erythritol sweetener
• 1/3 cup allulose (or xylitol)
• 6 tbsp unsweetened cocoa powder (Dutch-process preferred)
• 2 tbsp vodka (optional, keeps ice cream soft)
• 1 tsp vanilla extract
• 1/4 tsp xanthan gum
• A pinch of salt
• 1/2 cup natural, unsweetened peanut butter
• 1/2 tbsp butter

Detailed Step-by-Step Directions

1. Simmer the base: In a medium saucepan, whisk together heavy cream, almond milk, erythritol, allulose, and cocoa powder. Heat over medium-low until it reaches a gentle simmer. Cook for 5–10 minutes, stirring occasionally, until the mixture thickens slightly (it will coat the back of a spoon).
2. Flavor and thicken: Remove from heat. Stir in vanilla, salt, and vodka (if using). Sprinkle xanthan gum evenly over the surface, then whisk vigorously for about 30 seconds to avoid lumps. The texture should be silky smooth.
3. Chill completely: Let the chocolate base cool to room temperature, then cover and refrigerate for at least 2 hours (or overnight) until fully cold. This step is crucial for a creamy churn.
4. Churn it up: Pour the chilled mixture into your ice cream maker and churn according to the manufacturer’s instructions—usually 20–25 minutes. It will look like soft-serve.
5. Make the peanut butter swirl: While churning, combine peanut butter and butter in a small microwave-safe bowl. Heat in 15-second bursts, stirring between each, until smooth and drizzle-able. (Or use a small saucepan over low heat.)
6. Layer and swirl: Spoon half of the churned ice cream into a freezer-safe container. Drizzle half the melted peanut butter over it. Add the remaining ice cream, then top with the rest of the peanut butter. Gently swirl with a butter knife or skewer—don’t overmix, you want distinct ribbons.
7. Freeze to firm: Cover the container and freeze for 3–4 hours until scoopable. Scoop and enjoy your Keto Chocolate Peanut Butter Ice Cream!

Different Ways to Serve & Present

• Classic sundae: Top with sugar-free whipped cream, a sprinkle of cacao nibs, and a few keto-friendly chocolate chips.
• Peanut butter cup crunch: Crush a low-carb peanut butter cup and press it onto the surface of the ice cream before serving.
• Waffle bowl magic: Serve in a keto waffle bowl made with almond flour for extra texture.
• Shake it up: Blend 2 scoops of ice cream with 1/2 cup unsweetened almond milk for a thick, frosty milkshake.
• Ice cream sandwiches: Sandwich a scoop between two keto chocolate cookies—heavenly.

How to Store & How Long It Lasts

Store your Keto Chocolate Peanut Butter Ice Cream in an airtight, freezer-safe container. Press a piece of parchment paper or plastic wrap directly onto the surface of the ice cream before sealing—this prevents ice crystals from forming. When stored properly, it stays fresh and creamy for up to 3 weeks. For the best texture, let the ice cream sit at room temperature for 5–10 minutes before scooping. If you store it longer, it may become too hard, but a quick blast in the microwave (10 seconds) will soften it right up. Just don’t leave it out too long—keto ice cream melts faster than regular ice cream!

FAQs

1. Can I use a different sweetener?

Yes, but the texture may change. Allulose and erythritol work best together. Swapping both for allulose will create a softer, more scoopable ice cream. Using only erythritol may make it a bit grainy or hard.

2. Do I have to add vodka?

No, it’s optional. Vodka lowers the freezing point, which keeps the ice cream soft without affecting flavor. You can omit it or substitute with 1 tsp of vegetable glycerin.

3. Why did my ice cream turn out icy?

Icy texture usually means the base wasn’t chilled enough before churning, or it wasn’t stored airtight. Make sure you chill for at least 2 hours and press plastic wrap onto the surface.

4. Can I make this dairy-free?

Swap heavy cream for full-fat coconut cream (chilled) and use a dairy-free butter substitute. The flavor will shift slightly, but it’s still deliciously creamy.

5. Is peanut butter keto-friendly?

Yes, as long as it’s natural, unsweetened peanut butter with no added sugar. Check the label—ingredients should only be peanuts and salt.

6. Can I skip the xanthan gum?

You can, but the ice cream will be more prone to iciness. Xanthan gum helps stabilize the mixture. You can substitute with 1/2 tsp of guar gum or 1 tbsp of unflavored gelatin (bloomed).

7. How do I make this without an ice cream maker?

Pour the chilled base into a shallow dish, freeze for 1 hour, then stir vigorously with a fork. Repeat every 30 minutes for 3–4 hours until creamy. It won’t be as smooth, but it works.

8. Can I add mix-ins like chocolate chips?

Absolutely! Fold in sugar-free chocolate chips or chopped keto peanut butter cups after churning, just before the swirl step.

9. My peanut butter swirl is too thick—what should I do?

Add a teaspoon of coconut oil or extra butter to thin it out before drizzling. It should be runny enough to swirl easily but not watery.

10. How do I know if my ice cream is done churning?

When the volume has increased by about half and the mixture looks like soft-serve ice cream, it’s ready. A spoonful should hold its shape but still be fluffy.
