Why You’ll Love These Frozen Peanut Butter Cups

  • Diet-friendly dessert – These treats are perfect for Weight Watchers and anyone watching their calories – they give you that peanut butter cup satisfaction without the guilt.
  • 3-ingredient simplicity – With just whipped topping, powdered peanut butter, and optional chocolate syrup, you won’t need to run to the store for fancy ingredients.
  • No baking required – Just mix, freeze, and enjoy – no need to turn on the oven or deal with melting chocolate.
  • Customizable sweetness – You can adjust the amount of chocolate syrup or skip it entirely, making these treats perfectly suited to your taste preferences.

What Kind of Powdered Peanut Butter Should I Use?

Powdered peanut butter (also called peanut butter powder) comes in several brands, with PB2 and PBfit being the most common ones you’ll find at the grocery store. Both regular and chocolate-flavored versions will work in this recipe, though the regular variety gives you more control over the final flavor. The main difference between brands usually comes down to sugar content – some have added sugar while others are sugar-free, so check the label if you’re watching your sugar intake. Just make sure you’re using powdered peanut butter and not regular peanut butter, as the powder mixes much better with the whipped topping and helps maintain the right texture.

Options for Substitutions

Looking to make these treats but need to switch things up? Here are some helpful swaps:

  • Fat-free whipped topping: You can use light whipped topping instead of fat-free, though it will change the points value. Another option is making your own using light coconut cream (chilled and whipped) – just note this will add a slight coconut flavor.
  • Powdered peanut butter: This is a key ingredient for keeping the points low, but if you’re not concerned about points, regular peanut butter can work – use 1 tablespoon instead of 2. You could also try almond butter powder for a different nutty flavor.
  • Sugar-free chocolate syrup: Since this is optional, you can skip it entirely. You could also use sugar-free caramel syrup, or crushed sugar-free chocolate chips for some crunch. If points aren’t a concern, regular chocolate syrup works too.

Watch Out for These Mistakes While Making

The biggest challenge when making frozen peanut butter cups is not properly mixing the powdered peanut butter – make sure to blend it thoroughly with the whipped topping to avoid any dry, powdery patches in your treats.

Temperature control is crucial here – working too slowly with the whipped topping can cause it to become too soft and lose its structure, so keep your mixing time brief and have your molds ready before you start combining ingredients.

A common error is overfilling the molds or cups – fill them only about 3/4 full to allow for proper freezing and easy removal, and make sure to tap the filled cups gently on the counter to remove any air bubbles that could create holes in your finished treats.

For the smoothest results, freeze these cups for at least 2 hours before attempting to remove them from the molds, and let them sit at room temperature for just 1-2 minutes before serving to achieve the perfect texture.

What to Serve With Frozen Peanut Butter Cups?

These lightened-up frozen treats are perfect on their own, but they’re also great as part of a dessert spread! I like to serve them alongside a cup of hot coffee or unsweetened tea, since the warm drinks create a nice temperature contrast with the frozen cups. For a fun dessert party, try setting up a little sundae bar where people can add fresh banana slices, a few chopped nuts, or even a small drizzle of sugar-free caramel sauce to their peanut butter cups. If you’re keeping things Weight Watchers friendly, some fresh berries on the side add natural sweetness without extra points.

Storage Instructions

Keep Frozen: These peanut butter cups need to stay in the freezer to maintain their shape and texture. Place them in a freezer-safe container, and they’ll be good for up to 2 months. I like to separate layers with parchment paper to prevent them from sticking together.

Prepare Ahead: These treats are perfect for making in big batches! You can easily double or triple the recipe and keep them stocked in your freezer for whenever those sweet cravings hit. They’re ready to enjoy straight from the freezer – no thawing needed.

Serve: Take them out of the freezer about 1-2 minutes before eating to let them soften just slightly – they taste best when they’re still pretty firm but not rock-hard. Once they start to warm up too much, they’ll begin to lose their shape, so it’s best to keep them frozen until right before serving.

Ingredients

  • 1 tub fat-free whipped topping
  • 2 tablespoons powdered peanut butter
  • Sugar-free chocolate syrup (optional)

Step 1: Mix the Cool Whip and PB2 Powder

Start by adding one container of fat-free Cool Whip and 2 tablespoons of PB2 powder into a large bowl.

Mix thoroughly until the powder is fully incorporated into the Cool Whip, ensuring there are no clumps and the mixture is smooth.

Step 2: Prepare and Fill Cupcake Liners

Take seven cupcake liners and place them in a cupcake pan or on a baking sheet to keep them stable.

Divide the Cool Whip mixture equally among the seven liners, filling them with the mixture.

For an optional touch, add a swirl of calorie-free chocolate syrup on top of each cup for added flavor and decoration.

Step 3: Freeze and Serve

Place the filled cupcake liners in the freezer for 4-5 hours, allowing them to fully harden into delicious Weight Watchers peanut butter cups.

Once frozen, enjoy them straight from the freezer for a cold treat, or let them thaw for a few minutes for a slightly softer consistency.

Enjoy!
