Use your measuring cups but first spray them with Pam to let the peanut butter slide out easily.

fill a measuring cup with cold water to the maximum of the cup minus the amount of peanut butter you need...I.e. For 1/2 cup, fill a two cup measuring cup with 1-1/2 cups water, drop peanut butter in until water gets to 2 cup line....drain and use the peanut butter...voila, perfect measure

Put water in measuring cup. Displace water by adding pb until it equals the amount calls for. Discard water

I just pack it into the measuring cup and allow a little extra for voids in the packing. Most recipes are robust enough that the measurement needn't be exact. As a fan of Alton Brown, he nearly always advocates measuring by weight. You just need to weigh one well-packed cup so that you can use that number in the future. If you don't have one, small electronic kitchen scales can be had for less than ten bucks. I love mine.

Oil your measuring cup first so it slides out easily.

Wet the measuring cup with water, then add the peanut butter. It will come out of the cup easier than without it. The best way is with an adjustable measuring cup like this: https://www.lehmans.com/product/15510/measuring?utm_medium=shoppingengine&utm_source=googlebase&utm_campaign=1029130&zmam=32933335&zmas=1&zmac=1&zmap=1029130&partner_id=bcbgoog&utm_source=google&utm_medium=cpc&utm_campaign=NB_PLA_AllProducts_GOOG&utm_term=shopping&utm_content=sh0dHZdsM_dc|pcrid|54869971724|pkw||pmt||&&gclid=EAIaIQobChMI2-z7_Lj61gIVE7nACh2I4wr3EAQYAyABEgIXrvD_BwE

Scoop into a measuring cup that is for solids, not liquids. Press it down, level it off with the back of a knife.

I just eyeball it cuz you can never have too much peanut butter! yum
