Eloise Moon If you’ve ever pulled into a drive-thru on a hot day just to order a frosty, you know the joy of diving into that creamy, icy dessert. It’s smooth, indulgent, and just the right balance between a milkshake and soft-serve. But there’s one big catch: the original versions are loaded with refined sugar, artificial flavors, and ingredients that don’t exactly scream healthy lifestyle.
That’s where this homemade Peanut Butter Frosty comes in. It captures everything you love about the traditional treat—the thick, spoonable texture, the melt-in-your-mouth creaminess, and the sweet comfort factor—but it’s made with wholesome ingredients. Instead of sugar overload, you’ll get natural sweetness, plant-based creaminess, and the irresistible richness of peanut butter.
Whether you’re craving a late-night dessert, need a post-workout shake, or want to whip up a quick breakfast smoothie, this recipe checks every box. By the time you finish reading, you’ll not only know how to make this frosty at home but also understand why it’s healthier, how to customize it, and how to fit it into your daily routine.
What Is a Frosty and Why Add Peanut Butter?
The original frosty, invented decades ago, is something between a milkshake and soft-serve ice cream. It’s eaten with a spoon but has enough creaminess to sip through a straw. The main appeal lies in its silky consistency and subtle sweetness.
However, the classic version is made from milk, cream, sugar, and stabilizers. While delicious, it’s not exactly ideal for someone watching their sugar intake, balancing macros, or looking for nutrient-rich snacks.
By adding peanut butter into the equation, we elevate the frosty in two ways:
- Flavor boost: Peanut butter adds a nutty depth that balances sweetness beautifully.
- Nutrition upgrade: Instead of empty calories, you get protein, healthy fats, and lasting satiety.
Think of it as a dessert-meets-smoothie hybrid: indulgent enough for a sweet tooth, nourishing enough for a post-gym recharge.
Why This Recipe Works
Unlike many “healthy” dessert recipes that end up tasting bland, this frosty nails both taste and texture. Here’s why:
- Frozen bananas (or ice for low-carb) replicate the creamy body of ice cream without dairy.
- Natural peanut butter adds richness without processed oils or sugar.
- Almond milk or your milk of choice makes the blend light yet creamy.
- Vanilla extract enhances the sweet, dessert-like vibe.
- Optional protein powder or Greek yogurt makes it more filling.
The result is a silky, thick frosty that feels indulgent while nourishing your body.
Ingredients You’ll Need
This recipe makes 2 servings.
- 1 large frozen banana (or 1½ cups ice for low-sugar version)
- 3 tablespoons natural peanut butter (no added sugar or oil)
- ½ cup unsweetened almond milk (or oat, cashew, dairy—your choice)
- ½ teaspoon vanilla extract
- 1–2 tablespoons maple syrup, honey, or sugar-free sweetener (optional, adjust to taste)
- Pinch of salt (enhances peanut flavor)
- Optional: 1–2 tablespoons plain or vanilla Greek yogurt (extra creaminess)
- Optional: 1 scoop vanilla or chocolate protein powder (great for workout recovery)
Kitchen Tools You’ll Need
You don’t need fancy equipment, but a few tools make things easier:
- High-speed blender or food processor (for that silky texture)
- Measuring cups and spoons
- Spatula (to scrape the blender sides)
- Glasses or bowls for serving
- Reusable straw or spoon (depending on your frosty thickness)
Step-by-Step Instructions
- Add the base ingredients. Place the frozen banana (or ice), peanut butter, almond milk, vanilla, sweetener, and salt into your blender.
- Blend until smooth. Start low, then increase to high speed until thick and creamy. You may need to stop and scrape the sides.
- Adjust texture. If it’s too thick, add a splash more milk. If too thin, add extra ice.
- Taste test. Adjust sweetness or peanut butter as needed.
- Serve immediately. Pour into glasses or bowls. Garnish with a peanut butter drizzle, cacao nibs, or granola if desired.
Tips for Creaminess & Flavor Balance
- Use ripe bananas before freezing for natural sweetness.
- Add a pinch of sea salt to highlight the nutty flavor.
- For dairy-free creaminess, use oat milk or cashew milk.

- For a nut-free version, swap peanut butter with sunflower seed butter or tahini.
