can you dehydrate cheesecake?

that might be a stupid question 😭 i’m trying to make different kinds of icecream and one of the ones i’ve made is cheese cake - when i made it all i did was put cream cheese, strawberries and graham crackers into the base, mixed it and froze it. i’ve been looking at restaurant chains such as dairy queen and how they have cheesecake chunks in their blizzards — is it actual cheesecake? if so is it dehydrated? or freeze dried? also what is the difference between dehydration and freeze drying? i try and find freeze dryers and dehydrators are the things coming up😭 thanks in advance!! submitted by /u/Euphorickaspbrak
