First time finding your channel and you’re talking about iced blondies. I’ve only purchased them from my local coffee place and they mistakenly told me what they use. I make them* at home now. What I use: blondie espresso shots (Starbucks brand) whole milk and Cookie Butter syrup. It’s amazing all the time but I say it tastes like the holidays. I put the syrup first, ice, milk, espresso on top. Incase you ever want to try it at home. ❤
