Ingredients

This recipe makes about 2 ½ cups of dip (serves 8–10 people).

Base Ingredients:

• 1 cup creamy peanut butter
• 1 cup marshmallow fluff
• 4 oz cream cheese, softened
• ½ cup powdered sugar
• ½ teaspoon vanilla extract
• 2–3 tablespoons milk (as needed for consistency)

Optional Add-Ins:

• ¼ cup mini chocolate chips
• 2 tablespoons cocoa powder (for chocolate version)
• ¼ cup crushed peanuts
• 2 tablespoons caramel sauce
• Pinch of salt (for salted peanut butter flavor)

Step 1: Soften Ingredients

Make sure your cream cheese is fully softened to room temperature. This ensures a smooth, lump-free dip.

If your peanut butter is stiff, microwave it for 10–15 seconds to loosen slightly.

Step 2: Beat the Base

In a mixing bowl, beat together:

• Cream cheese
• Peanut butter

Mix until completely smooth and creamy.

This step creates the rich base and prevents lumps later.

Step 3: Add Marshmallow Fluff

Add the marshmallow fluff and vanilla extract.

Beat again until fully incorporated.

The mixture should start looking light and fluffy.

Step 4: Sweeten and Adjust Texture

Add powdered sugar and mix until smooth.

If the dip feels too thick, add milk one tablespoon at a time until it reaches your desired consistency.

You want it thick enough to hold shape but soft enough for easy dipping.

Step 5: Fold in Extras (Optional)

Now’s the time to customize:

• Fold in mini chocolate chips
• Stir in crushed peanuts for crunch
• Swirl in caramel sauce
• Add cocoa powder for a chocolate peanut butter version

Keep it simple or load it up—it’s flexible.
