Step 1: Mix the Peanut Butter and Marshmallow Cream
In a medium-sized bowl, combine the creamy peanut butter and marshmallow cream. Use a spatula or a whisk to thoroughly mix these two ingredients until they are well incorporated. The mixture should be smooth and evenly combined, with a fluffy consistency.

Step 2: Add Vanilla Extract
Next, add the vanilla extract to the mixture. Stir well to ensure the vanilla is evenly distributed throughout the fluff. The vanilla adds a depth of flavor, making the fluff even more delicious.

Step 3: Adjust Consistency (Optional)
If you prefer a thinner consistency for your fluff, you can gradually add milk. Start with one tablespoon at a time, mixing well after each addition. Continue adding milk until you reach your desired thickness. This step is optional, depending on how you like your fluff.

Step 4: Serve and Enjoy
Your Peanut Butter Fluff is now ready to be served! You can enjoy it immediately with your favorite dippers like sliced apples, bananas, graham crackers, or even pretzels for a sweet and salty combo. If you have any leftovers, store the fluff in an airtight container in the refrigerator for up to 5 days.
