Ice cream (regardless of brand) will not contain gluten, unless one of the add ins contains gluten (e.g. cookie pieces, brownie chunks) which are usually rather obvious things that outside of ice cream would normally be expected to contain gluten unless explicitly labeled "gluten free".
According to the company that makes the ice cream you asked about, the birthday cake flavor ice cream is NOT gluten free. Any flavor that includes gluten-laden ingredients in the title or pieces of the stated items such as cookies, cake pieces, pie crust pieces, graham cracker pieces, ice cream cone pieces, or anything that contains wheat, rye, barley (malted), or oats, etc., are not gluten free. Best to stick to flavors that do not contain these items or that are specifically labeled gluten free on the package.
Toffee and hundreds and thousands. ( sprinkles)
The ice cream itself is gluten free. But you have to be careful of toppings (no cookies, no graham cracker crust, no malts) and cross contamination. If you want a Blizzard, ask them to wash the blender apparatus first, or stick to sundaes/ice cream products that don't have to touch other implements. Most chains will have an allergen chart on their website to let you know which products are safe. If you have questions, be sure to ask the manager at your local store.
