Keto Wendy’s Frosty (Copycat Recipe)
Why This Works
Heavy Cream & Almond Milk – Together, they mimic ice cream’s richness but keep carbs low. Heavy cream gives a silky, scoopable texture, while unsweetened almond milk lightens it up so it isn’t too heavy.
Keystone Pantry Allulose – Our sweetener of choice. Allulose not only provides a clean, sugar-like sweetness but also helps keep the Frosty scoopable instead of turning rock-solid when frozen.
Cocoa Powder – Unsweetened cocoa provides that classic chocolate taste. A touch of vanilla rounds out the flavor and prevents bitterness.
Collagen or Whey Protein (optional) – A scoop can add body and that “malty” mouthfeel that Wendy’s Frosty is known for.
Blending & Freezing – Instead of churning, we blend and partially freeze, which gives it that thick, almost soft-serve consistency.
Ingredients (Makes about 4 servings)
1 cup heavy cream
1 ½ cups unsweetened almond milk (or macadamia milk for extra creaminess)
Optional: 1 scoop collagen peptides or whey protein isolate
Instructions
In a mixing bowl, whisk together cocoa powder, allulose, and salt to remove clumps.
Add heavy cream, almond milk, and vanilla. Blend with a hand mixer or in a high-powered blender until smooth and slightly frothy.
Taste and adjust sweetness if needed.
Pour mixture into a shallow dish or freezer-safe container. Freeze for 30–45 minutes.
Remove from freezer, stir well, then return to freezer. Repeat every 30 minutes for 2–3 hours until the mixture reaches a thick, Frosty-like consistency.
Alternatively, run the mixture through an ice cream maker for faster results.
Serve with a spoon or straw, just like the real thing!

FAQ
Q: Can I make this dairy-free? Yes! Swap heavy cream for coconut cream, and it still turns out rich and creamy.
Q: Can I make it thicker, like soft-serve? Definitely. Blend in ½ avocado or 2 oz cream cheese for extra thickness without changing flavor.
Q: Can I store leftovers? Yes, but it will harden in the freezer. To serve again, let it thaw for 15–20 minutes, then re-blend until smooth.
Q: Why allulose instead of erythritol or stevia? Allulose prevents crystallization and keeps the Frosty creamy instead of icy. Erythritol tends to make frozen desserts gritty.
