Combine butter, dried cranberries, jalapenos, cilantro, flaky salt and black pepper in a bowl. Mix with a rubber spatula until smooth and combined.
Scrape mixture into a silicone dome baking mold, pressing it firmly inside. Cover and chill until firm. Alternatively, scrape mixture onto a sheet of plastic wrap and form into a ball. Chill, rotating and shaping ball every 15-20 minutes until smooth, round and hard.
Remove from mold, let soften 20 minutes at room temperature, then serve with crackers and crusty bread.
