Just an idea; while at Dairy Queen this week I saw a new Blizzard flavor, strawberry with golden Oreos and I'm thinking that that might make for a good filling. A twist on cookies and cream. Maybe a strawberry buttercream with the crushed cookies. Now that I think of it DQ makes a lot of good Blizzards that could work, the Thin Mint one? Mmmm.
I agree! That sounds yummy!
