It turns out that the key to getting your hands on your favorite discontinued Dairy Queen treats (like the vintage Dixie Belle Sundae) is the DQ secret menu. If your local DQ has the ingredients, they can make just about any classic treat — you just need to provide them with the recipe.

For a Dixie Belle Sundae, all you need to do is "ask for a regular hot fudge one, add butterscotch, and finish with pecans." The old-school Peanut Butter Bash, on the other hand, is created by pouring some peanut butter sauce and hot fudge into the bottom of the sundae cup, adding vanilla soft serve, and then pouring the sauce duo on the top.

Similarly, the nostalgic Jack and Jill is simply a sundae with marshmallows poured down one side of the soft serve and hot fudge down the other. Some other DQ secret menu favorites include the Peanut Butter and Jelly shake, Banana Split Blizzard, and a 1950s-style chocolate soda — which you can easily get if you know the recipe and remember your "P's" and "Q's."
