Peanut butter often keeps its smooth texture, but if it's not closed properly, it can occasionally dry up and become dense. Fortunately,

all you have to do is heat it up.

Heating peanut butter can soften and thin it out without changing its flavor in any way. You can either heat it up on the stove or pop it in the microwave.

In a small pan, heat the peanut butter over low heat, stirring regularly, until it softens, or microwave on

high for 20 seconds, adding extra

10-second intervals if needed.
