My favorite ice cream flavor has always been peanut butter. There's just something about it. However, I don't always have the time to whip up a batch of homemade ice cream.

That's why I came up with this keto-friendly ice cream topping for peanut butter lovers just like me. It's a quick and easy way to get the flavor into store bought low-carb ice cream. I don't even bother heating up the leftovers.

I just mix a little bit of this luscious keto peanut butter sauce into sugar-free vanilla ice cream to satisfy my craving. In the summer, it's just what I need for an after work snack. I feel like I'm treating myself at an ice cream shop.

If you love peanut butter too, you are going to love this peanut butter ice cream topping!

📋 Ingredients

You only need 3 simple ingredients to make the sauce! The recipe calls for natural peanut butter, sweetener, and water. That's it!

Almond milk can be used to thin out the sauce and make it a little creamier. A little salt may be needed too if you use an unsalted peanut butter.

🔪 Instructions

This peanut butter sauce recipe is super simple. You just make a simple syrup on the stove top. Then stir in the creamy peanut butter.

Here's more details on the steps:

• Combine sweetener and water in a medium saucepan over high heat and boil for a minute.

• Remove sweetened water from heat and stir in the natural peanut butter until a desired consistency is reached. Add more water or almond milk as needed.

That's all there is to making a homemade peanut butter sauce for ice cream! I do find that stirring in a dash of salt gives it a better flavor.

🍽️ Serving suggestions

This is the perfect sauce to serve warm over any kind of ice cream. It makes the perfect peanut butter sundae. I like to swirl it in so that the yummy flavor is in every bite.

It's a great addition to my keto frozen custard and dairy-free chocolate ice cream recipes. Sometimes, I'll swirl the sauce into my homemade ice cream before it freezes.

You can even use it to make peanut butter cup ice cream sundaes! Just top keto vanilla ice cream with the peanut butter sauce and sugar free hot fudge sauce. Then top with sprinkle on chopped low-carb peanut butter cups and garnish with keto whipped cream.

🥫 Storage and reheating

Although it can be left out at room temperature, it's best to store the peanut butter sauce in the refrigerator. If you do use almond milk to thin out the sauce, you'll definitely want to keep it chilled.

To heat up the cold sauce, just place two tablespoons in a small microwaveable bowl and microwave on high for about 20 seconds. You can also reheat it on the stove if you prefer.

📒 Thinning the sauce

If you need to thin out the peanut butter topping, simply stir in a little water or almond milk into the warm sauce. You can also use heavy cream if you'd like the peanut butter sauce to be a little creamier.

💭 Tips and variations

You can use the recipe with any nut or seed butter to easily change the flavor. Sunflower seed butter is a great option for those with a peanut allergy.

The sweetener can also be cut back and seasonings added to make this more of a Thai-inspired peanut sauce. Just add in a little tamari (or coconut aminos for soy free), garlic, and a little lemon or lime juice. A dash of red pepper flakes can be added to spice it up.
