Dekuyper Thrilla Vanilla
Choose the product options first
Just as with the original, this clone of the unique vanilla liqueur from DeKuyper can be mixed with cola over ice, or with 1 part vanilla liqueur to 2 parts raspberry liqueur for another tasty tipple. Also try splashing some of it into the shaker with your favorite vodka for a sweet vanilla-tini.
