Start with the anti-clump base
In a medium bowl, whisk together the butter powder and cornstarch until completely smooth and lump-free.
Add the sugars
Add the turbinado sugar and brown sugar. Use your fingers or a fork to break up any brown sugar clumps before mixing further.
Flavor + balance
Sprinkle in the fine sea salt and vanilla powder.
Whisk thoroughly
Whisk for a full 30–45 seconds, lifting and turning the mixture until color and texture are evenly distributed throughout.
Jar it up
Funnel the sprinkles into a clean, completely dry half-pint mason jar.
Tap the jar gently on the counter to settle, then seal tightly.
