I love the round sprinkles! But after extensive Googling, I've not been able to locate anything similar. Any advice?

CALLEBAUT Chocolate Dark Crispearls, 1 LB
by Callebaut on Amazon... there's also a milk chocolate version

The "sprinkles" look like Valhrona Pearls to me. They have them at Sur La Table.

It looks like 'chocolate pearls' were used instead of 'sprinkles.' These can be found at any cake supply store. I know I have seen them at Sur la Table, Williams Sonoma & possibly Whole Foods. Yes, Michael's craft store sells them too (I think.) Wilton is one company that makes them.

Do you mean sixlets - something like these: https://www.shorecakesupply.com/product/sixlet-chocolate-candies/ ? If so, I've found them in the baking aisle of grocery stores regularly, Michael's (yes the crafting store), or other websites should have them. Happy anniversary!
