Pop your oven to 350°F (175°C) and line two pans with some parchment paper.
02 -
Dump the frozen raspberries onto a board and chop them fine. Leave them nearby for later.
03 -
Toss the lemon zest and white sugar in a bowl. Rub them together with your hands to really get that citrus smell going.
04 -
Add soft butter and brown sugar to the bowl. Mix it up on medium-high so it gets light and creamy for about 3 or 4 minutes.
05 -
Crack in the yolk, splash in the vanilla, pour in lemon juice. Mix just until it starts coming together. Don’t overdo it.
06 -
Add salt, baking soda, baking powder, and flour to the bowl. Stir by hand until you still see a bit of flour—stop! That keeps cookies tender.
07 -
Drop the chopped raspberries in now, stir just enough to spread them out. Don’t stir too much or the color gets wild.
08 -
Scoop up big blobs—about three tablespoons each—plop five onto each tray. Hit them with a sprinkle of flaked salt.
09 -
Slide trays in for 12 to 15 minutes. When edges start to brown, pull the trays. Let them chill on the tray so they firm up a bit.
