My #1 favorite is only available in Santa Cruz, CA, where I only get to go once a year. It's at Marianne's Ice Cream... Alice B. Toklas Fudge Brownie. Always need a double-scoop of that one!
Also love Baskin-Robbins Cherries Jubilee, as well as Peanut Butter & Chocolate.
Oh yes, and at Cold Stone Creamery, I love to get Sweet Cream ice cream with black cherries and blackberries mixed in. Yum!
