Marshmallow Fluff
Marshmallow fluff (crème) weighs 200g per cup. A spreadable version of marshmallow made from egg whites, sugar syrup, and vanilla — the base of fluffernutter sandwiches, fudge, and the classic Whoopie pie filling. Substitutes for 4 cups mini marshmallows in any melted application (about 7g fluff per marshmallow). Doesn't melt as cleanly as marshmallows — work it briefly into warm mixtures rather than expecting it to dissolve. Stays soft and spreadable at room temperature for months.

03 // WHY IT MATTERS
If your cookies spread, your bread is gummy, or your cake sinks — flour weight is usually why.
A scooped cup of flour can weigh anywhere from 125g to 180g. That's a 44% range — enough to wreck a cake.
Modern recipes use the spoon-and-level method: fluff the flour, spoon it into a dry measuring cup without packing, then sweep flat with a knife.
The scoop method — pushing the cup directly into the bag — packs in 40-50% more flour.
