Oat milk in the fridge and a jar of peanut butter were basically begging for this. Peanut Butter Oat Milk Ice Cream is oat milk, creamy peanut butter, maple syrup, and vanilla, frozen overnight and spun in the Ninja Creami into a soft, dairy-free scoop that tastes like a frozen peanut butter cup minus the chocolate. My son, who eats peanut butter on everything, declared it the best thing I've made all summer. Use the smooth no-stir peanut butter, because the natural kind that separates can freeze unevenly and leave you with oily streaks.
How it spins
Tip: freeze the pint on a level shelf for a full 24 hours. If the first spin looks crumbly, add a splash of milk and run Re-spin.
Ingredients
- Oat Milk1.25 cup
- Creamy Peanut Butter3 tbsp
- Maple Syrup3 tbsp
- Vanilla Extract0.5 tsp
- Chopped Peanutsoptional2 tbsp
Directions
- 1Blend the oat milk, peanut butter, maple syrup, and vanilla until completely smooth.
- 2Pour into a Creami pint, staying under the fill line.
- 3Freeze flat for roughly 24 hours.
- 4Run the ICE CREAM preset.
- 5Add a tablespoon or two of oat milk and Re-spin if the texture is crumbly.
- 6Make a hole in the center, add the chopped peanuts as a mix-in, and run the Mix-In program; then serve.
Tips
- Freeze your peanut butter mixture completely solid for the full 16-24 hours - a partially frozen pint will spin into mush instead of creamy ice cream.
- If your first spin comes out too icy or crumbly, add just a splash of oat milk and re-spin using the Ice Cream setting to get that smooth texture.
- Warm your peanut butter slightly before mixing it into the oat milk so it blends smoothly without lumps that won't freeze evenly.
Variations
- Swirl in 2-3 tablespoons of chocolate syrup or cocoa powder mixed with a bit of maple syrup before freezing for a chocolate-peanut butter version.
- Use almond butter or sunflower seed butter instead of peanut butter if you need a nut-free option, keeping the same amounts of maple syrup and vanilla.
- Add 1-2 tablespoons of honey or agave alongside the maple syrup for extra sweetness and a slightly different flavor depth.
FAQ
- Can I use natural peanut butter with the oil on top?
- You can, but it's trickier - the oil may separate unevenly as it freezes, creating inconsistent texture when spun. Creamy peanut butter with added stabilizers freezes more reliably and spins smoother.
- My pint came out crumbly instead of creamy. What went wrong?
- The mixture either didn't freeze solid enough, or your freezer is too cold and icy. Add a splash of oat milk and re-spin on the Ice Cream setting, or let the pint sit at room temperature for 2-3 minutes before spinning again.
- How long can I keep a frozen pint in the freezer?
- Your pint will stay good for up to 2 weeks frozen, though the longer it sits the icier it may become. You can re-spin it with a small splash of oat milk to restore the texture anytime.
- Can I make this lighter or lower in calories?
- Use a light or low-fat peanut butter and reduce the peanut butter amount to 1/2 cup while keeping the maple syrup at 3-4 tablespoons, then spin on the Lite Ice Cream setting for a fluffier, airier result.
