Creamy Peanut Butter Banana Soft Serve
A rich, creamy frozen dessert made by blending frozen bananas with smooth peanut butter and milk. No churning required—the frozen bananas create a naturally soft, scoopable texture that's ready to eat straight from the blender. Perfect for a quick treat on a warm day.
Steps
Before you start
- Slice and freeze bananas ahead of time (at least 4 hours, or overnight).
- Use a high-powered blender or food processor for smooth results.
- Have all ingredients at hand—the frozen bananas will start to thaw quickly once removed from the freezer.
Prepare frozen bananas
- If you haven't already, peel ripe bananas and slice them into 1-inch (2.5 cm) rounds.
- Spread them on a parchment-lined baking sheet and freeze until solid, at least 4 hours or overnight.
- Transfer to a freezer bag for storage.

Ready when: Banana slices are completely frozen solid
Tip: Use ripe bananas with yellow skin and a few brown spots—they're sweeter and creamier than greener ones.
Combine ingredients in blender
- Add the frozen banana slices to a high-powered blender.
- Pour in the cold milk, add the peanut butter, honey, and vanilla extract.
- Do not blend yet—let the ingredients sit for 1 minute to allow the frozen bananas to soften slightly, which makes blending easier.

Tip: Use a high-powered blender like a Vitamix or Ninja for the smoothest texture; a standard blender may struggle with the frozen fruit.
Blend until creamy
- Start the blender on low speed, then gradually increase to medium-high.
- Blend for 60–90 seconds, pausing to scrape down the sides with a spatula as needed, until the mixture reaches a soft-serve consistency.
- It should look thick and creamy, like ice cream, with no visible chunks of banana.

Ready when: Mixture is thick, creamy, and soft-serve consistency with no lumps
Tip: Don't overblend—once it reaches soft-serve texture, stop immediately. Over-processing will turn it too soft or liquid.
Season and serve
- Taste the soft serve and add a tiny pinch of sea salt if desired (it enhances the peanut butter flavor).
- Scoop immediately into bowls or cones and serve at once, as the mixture will begin to thaw.

Tips
- For a creamier, richer soft serve, replace half the milk with Greek yogurt or 1–2 tablespoons of heavy cream.
- Add 1 tablespoon of cocoa powder to the blender for a chocolate-peanut butter version.
- If your blender struggles, add the milk first, then the banana slices, so the liquid helps break down the frozen fruit.
- Freeze your serving bowls or glasses for 15 minutes before scooping to extend the soft-serve texture.
Make ahead
You can prepare and freeze banana slices up to 3 weeks ahead. Store in a freezer bag. Blend just before serving for the best soft-serve texture.
Storage & reheating
This soft serve is best eaten immediately. If you have leftovers, transfer to an airtight container and freeze for up to 2 hours—it will be firmer but still enjoyable. Thaw slightly (5 minutes at room temperature) before scooping if it becomes too hard.
Substitutions
- smooth peanut butter → Almond butter or sunflower seed butter. Use the same amount for a milder flavor and nut-free (if using sunflower) option.
- whole milk, cold → Oat milk, almond milk, or coconut milk. Any cold milk works; use the same amount. Coconut milk will add a subtle tropical note.
- honey → Maple syrup or agave nectar. Use the same amount for a different sweetness profile.
- vanilla extract → Cinnamon (¼ teaspoon) or omit entirely. Cinnamon pairs beautifully with peanut butter; vanilla is optional if you prefer a purer peanut-banana flavor.
