Ingredients You’ll Need
What makes this recipe so wonderful is how a handful of simple, everyday goodies transform into something magical. Each ingredient has a job—some add creaminess, others bring depth or a whisper of sweetness, and together, they create pure frosty bliss.
- Frozen banana: Makes the shake perfectly thick and creamy while adding natural sweetness—don’t skip the freezing, it’s essential!
- Natural peanut butter: Delivers rich, nutty flavor and an irresistible velvety texture; opt for a no-sugar-added version for best results.
- Unsweetened cocoa powder: Provides that deep chocolatey essence, balancing out the banana and peanut butter.
- Unsweetened almond milk (or milk of choice): Keeps things light and dairy-free while blending everything smoothly—feel free to use oat or regular milk if you prefer.
- Vanilla extract: Just a splash heightens all the other flavors, rounding out each sip.
- Ice cubes: Helps achieve that frosty, almost soft-serve consistency for the ultimate Peanut Butter Frosty experience.
- Pinch of salt: A little goes a long way in making the chocolate and peanut butter pop!
- Optional maple syrup or honey: Adds a touch of extra sweetness if you’re in the mood for dessert-level decadence.
How to Make Peanut Butter Frosty
Step 1: Gather and Prep Your Ingredients
Check that your banana is fully frozen (always a good excuse to keep a few peeled bananas in the freezer!). Lay out the remaining ingredients to make the blending process smooth and speedy.
Step 2: Blend Everything Together
Add the frozen banana, natural peanut butter, cocoa powder, almond milk, vanilla extract, ice cubes, and a pinch of salt to your high-speed blender. Secure the lid and blend on high; you might need to pause and scrape down the sides to ensure everything is incorporated. You want a thick, creamy shake with no banana chunks left—don’t rush it!
Step 3: Taste and Adjust Sweetness
Give your Peanut Butter Frosty a little taste-test. If you want it sweeter (especially if your banana wasn’t ultra-ripe), add maple syrup or honey. Blend again for a few seconds and check the texture and flavor.
Step 4: Pour and Serve
Transfer your frosty into a chilled glass. It’s meant to be thick—serve with a wide straw or a spoon for the true frosty effect. Don’t be surprised if you find yourself scraping the glass for every last drop!
How to Serve Peanut Butter Frosty

Garnishes
You can make your Peanut Butter Frosty even more irresistible with delicious toppings. Try a sprinkle of mini chocolate chips, a dusting of cocoa powder, or a swirl of extra peanut butter on top. A little flaky sea salt adds a sophisticated touch that elevates all the flavors.
Side Dishes
While this creamy shake can easily stand alone, it’s fantastic alongside crunchy snacks like homemade granola clusters, peanut butter cookies, or crisp apple slices. These pairings provide a lovely contrast to the shake’s smooth richness.
Creative Ways to Present
For a party-ready twist, pour your Peanut Butter Frosty into small dessert cups and garnish each with a banana slice and a drizzle of chocolate syrup. Or, serve in mini mason jars for a fun, nostalgic vibe. Freezing the glasses ahead of time also keeps the frosty ultra-cold and creamy.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers (which is rare!), pour the rest into an airtight container and store it in the fridge. Keep in mind, the texture will soften a bit, but a quick stir or shake will bring it back to life as a drinkable dessert.
Freezing
For longer storage, freeze any extra Peanut Butter Frosty in a sealed container. When you’re ready to enjoy it again, let it sit at room temperature for 10–15 minutes, then stir or re-blend for that signature soft-serve consistency.
Reheating
This is one treat that’s meant to stay cold! If your frosty is too firm from the freezer, let it thaw briefly on the counter or blend with a splash of milk to restore its thick, creamy magic. Heating isn’t recommended, as it’ll lose the signature frosty experience.
FAQs
Can I use a different nut butter instead of peanut butter?
Absolutely! Almond or cashew butter work beautifully in this recipe. Each alternative brings its unique flavor, so feel free to experiment, but peanut butter delivers that classic Peanut Butter Frosty flavor that’s hard to beat.
Is there a way to make it even thicker?
Definitely—try freezing your almond milk in ice cube trays and using those instead of regular ice! You can also add a scoop of protein powder or a little extra frozen banana for a truly spoonable frosty.
Is it possible to make this without a frozen banana?
If you don’t have a frozen banana handy, substitute with a handful of ice and a tablespoon of your favorite sweetener, though the texture and natural creaminess of the Peanut Butter Frosty do benefit from the banana.
Is the Peanut Butter Frosty healthy?
This recipe is lighter than traditional milkshakes or fast-food frosties! It uses wholesome, plant-based ingredients, is naturally gluten-free, and contains healthy fats and protein—especially if you add a scoop of protein powder as suggested in the notes.
Can I double or triple the recipe?
Absolutely, especially if you have a larger blender. Just keep the ratios consistent and blend in batches if needed. The Peanut Butter Frosty is perfect for sharing with friends and family!
