Soft chewy cookies with white chocolate and pockets of raspberry. Sixteen cookies.
Work fast once the raspberries go in
Which the recipe flags and which is the whole difficulty here.
Frozen raspberries begin thawing the moment they meet room temperature dough. As they thaw they release juice, and that juice turns the dough wet, streaks it pink and makes scooping messy.
Fold them in last, scoop immediately, and get the tray into the oven. Having the sheet lined and the oven at temperature before you start is what makes this manageable.
If the dough does get wet, a few minutes in the fridge firms it enough to scoop.
Keep them frozen until the last moment
Half a cup.
Do not thaw them, and do not measure them out early to sit on the counter. Straight from the freezer into the bowl.
Frozen berries also hold their shape through folding. Thawed ones collapse into pulp and you lose the distinct pockets entirely.
Melted butter, not creamed
Three quarters of a cup.
This is why the cookies are chewy rather than cakey. Creaming butter with sugar builds air and gives a lighter, more cake-like crumb; melted butter skips that and gives a denser, chewier one.
It also means no mixer is needed. A bowl and a spatula covers the whole recipe.
Let it cool slightly before the egg goes in, or it starts cooking it.
An extra yolk
One whole egg plus one yolk.
Yolk is fat and emulsifier without the water that white brings. The extra one enriches the dough and adds to the chew, which is a common trick in cookies built for that texture.
Use the leftover white in something else rather than adding it.
Do not overmix
Which the method says twice, at the flour stage and again at the chocolate.
Mix until no streaks of flour remain and stop. Worked further, the gluten develops and the cookies turn tough rather than tender.
The chocolate gets folded rather than beaten in, for the same reason.
Brown sugar carries the dough
A full cup, against only a quarter cup of granulated.
Brown sugar holds moisture and it contains molasses, both of which contribute to a chewy cookie. A dough weighted the other way would be crisper and paler.
Pack it into the cup. Loosely measured brown sugar can be a third short by weight.
Twelve minutes and slightly underdone
Until the edges are golden and the centres have puffed but still look underbaked.
That is the correct read. Cookies continue setting on the hot tray after they come out, and one that looks done in the oven is dry by the time it cools.
Golden edges plus a soft centre is the pair of cues.
A one ounce scoop, two inches apart
Which gives sixteen.
Consistent size matters in a twelve minute bake, since a cookie half again as large will still be raw when its neighbours are done.
Two inches allows for spread. These are melted-butter cookies and they spread more than a creamed dough would.
Cool before eating
Which the method ends on.
Raspberry pockets are extremely hot straight from the oven, hotter than the cookie around them, since fruit holds heat. They also need a few minutes to stop being molten.
The cookie is fragile while warm too. Ten minutes on the tray is sensible.
White chocolate specifically
A cup of chips.
White chocolate is sweeter and more buttery than dark, and against tart raspberry that contrast is the point of the combination. Dark chocolate would compete with the fruit rather than balancing it.

Fresh raspberries
The recipe is built on frozen and that is deliberate. Fresh raspberries are far more fragile and collapse into the dough as you fold, streaking it and adding moisture. Freeze fresh ones solid first if that is all you have.
Storing
Three days at room temperature in an airtight container. They soften over time as the raspberry moisture migrates into the crumb.
White Chocolate Raspberry Cookies
Description
Chewy white chocolate cookies with pockets of tart raspberry, made in one bowl without a mixer.
Ingredients
Instructions
-
Preheat the oven to 350F and line a baking sheet with parchment paper. Have everything ready before you start, since the raspberries go in at the last moment.
-
In a large mixing bowl combine the slightly cooled melted butter, brown sugar and granulated sugar and mix until fully combined. Add the egg, egg yolk and vanilla and mix well.
-
In a separate bowl mix the flour, salt and baking soda. Add the dry ingredients to the wet and mix until just combined with no streaks of flour remaining. Fold in the white chocolate chips without overmixing.
-
Fold in the frozen raspberries, straight from the freezer, until evenly distributed.
-
Working quickly, use a 1 ounce cookie scoop to portion rounded dough balls, since the dough gets wet as the raspberries thaw. Place 2 inches apart on the prepared sheet and bake 12 minutes, until the edges are golden and the centres have puffed and still look slightly underdone.
-
Allow to cool before eating, as the raspberry pockets stay very hot..
Note
Work quickly once the raspberries go in, which the source flags: frozen berries begin thawing on contact with room temperature dough and their juice makes it wet and pink. Fold them in last, scoop immediately and have the tray and oven ready beforehand; if the dough does get wet, chill it a few minutes. Keep the raspberries frozen until the moment they go in, since thawed ones collapse into pulp and you lose the distinct pockets. Melted butter rather than creamed is what makes these chewy rather than cakey, and it means no mixer is needed; cool it slightly before the egg. The extra yolk adds fat without water for more chew. Do not overmix at either stage. Pull them at 12 minutes looking slightly underdone, since they set on the hot tray. Cool before eating, as raspberry pockets hold a lot of heat.
