Salt

Just a small amount balances the sweetness and makes all the flavors pop.

How to Make Homemade Fluffernutter Creamer

1. Blend

Add the half & half, sweetened condensed milk, powdered peanut butter, salt, marshmallow extract, and vanilla extract to a blender.

Blend until completely smooth and creamy.

2. Store

Pour the creamer into a bottle or airtight container.

Refrigerate for up to 2 weeks.

3. Shake Before Using

The powdered peanut butter may naturally settle over time, so give the bottle a good shake before pouring into your coffee.

Dairy-Free Option

To make this recipe dairy-free, simply substitute:

• Dairy-free half & half
• Dairy-free sweetened condensed milk (like sweetened condensed coconut milk or sweetened condensed oat milk)

The flavor stays just as creamy while remaining completely dairy-free!

Lower Sugar Option

For a lower sugar version, substitute the regular sweetened condensed milk with no sugar added sweetened condensed milk. This simple swap reduces the overall sugar while still maintaining a rich, creamy consistency.

Ways to Use Homemade Fluffernutter Creamer

This homemade creamer pairs beautifully with all kinds of coffee drinks.

Try it in:

• Iced coffee

• Iced Americanos

For the best flavor, start with 2–4 tablespoons of creamer per cup of coffee and adjust to taste.

Storage

Store your homemade coffee creamer in an airtight bottle or mason jar in the refrigerator for up to 2 weeks.

Because this recipe contains real dairy (or dairy alternatives), always keep it refrigerated and discard if it develops any off smell or texture.

Tips for the Best Homemade Creamer

• Blend until completely smooth so the powdered peanut butter fully dissolves.
• Shake well before each use, as natural settling is normal.
• Store in a glass bottle or mason jar for easy pouring.
• This creamer is delicious in both hot and iced coffee, but especially shines in cold brew where the marshmallow flavor really comes through.

Frequently Asked Questions

Can I use regular peanut butter?

I don’t recommend it. Regular peanut butter contains oils that don’t blend as smoothly into coffee creamer and can separate more easily. Powdered peanut butter creates a much smoother, more stable creamer.

How long does homemade coffee creamer last?

Stored in an airtight container in the refrigerator, this Homemade Fluffernutter Creamer will stay fresh for up to 2 weeks.

Can I freeze homemade coffee creamer?

Yes! Freeze in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator and shake well before using.

Does the peanut butter powder settle?

Yes, some settling is completely normal because of the powdered peanut butter. Simply shake the bottle well before pouring.
