Caramelized White Chocolate and Walnut Cookies

caramelized white chocolate and walnut cookies

Hello! Just dropping in here with a new cookie recipe for you all: caramelized white chocolate and walnut! These are a quick-and-easy, must-have-cookies-ASAP recipe — it uses melted butter and cold eggs, so you can whip them up on a whim.

These cookies are a variation on the triple chocolate peppermint cookies I posted in December, but here we’re highlighting caramelized white chocolate (or blonde chocolate) — some melted straight into the dough, and more folded in at the end for maximum impact. Caramelized white chocolate has been a trending flavor in the dessert world for about a decade now — while plain white chocolate tends to taste overly sweet and one-note, roasting it produces more complex and toasty flavors. You can make your own caramelized white chocolate by simply chopping up high quality white chocolate and baking it (stirring often) at a 250F until golden and toasty (see this tutorial from David Lebovitz). Or you can buy something like Valrhona Dulcey.

To complement the caramelly sweetness of the chocolate, I added toasted walnuts and a generous pinch of flaky salt. If you don’t have walnuts, I think either toasted hazelnuts or pecans would work nicely here — or even macadamia nuts if you’re a fan of the white chocolate macadamia nut pairing! And while flaky salt is normally an optional garnish, I highly HIGHLY recommend it here. It really helps balance out the cookie and veer it ever so slightly into the salty-sweet category.

After mixing the dough, just a short chill (30 minutes in the fridge, or even 10 minutes in the freezer) helps control spread and produces cookies with a thick, blondie-ish centers. If you bake them straight after mixing, the cookies will spread more and not be quite as soft overall. In the photo below, the top cookie was baked from dough that was chilled for half an hour; the bottom cookie was baked straight after mixing.

These cookies don’t brown much, so just keep an eye on them and bake just until the edges are set but the centers still look soft. They’ll continue to cook and set up on the pan. Enjoy slightly warm with a cup of black coffee (or milk)!

Baker’s notes:

  • For perfectly round cookies, use a round cookie cutter slightly larger than your cookie or even a spoon or offset spatula to nudge the cookies into shape right after baking. You must do this right when the cookies come out of the oven when they are still a bit malleable.
  • Don’t want to bake all the cookies off at once? You can keep unbaked dough balls in the fridge for up to 3 days or freeze for longer storage. For cookies chilled longer than half an hour, I find they spread best if you bring them to room temperature before baking (just pull them out while the oven is preheating).

Caramelized White Chocolate and Walnut Cookies

Makes about 15 cookies | Adapted from Baked to Order

Ingredients:

  • 113g (1/2 c) unsalted butter, cubed
  • 1/2 tsp espresso powder (optional)
  • 150g chopped caramelized white or blonde chocolate (such as Valrhona Dulcey), divided
  • 175g (1 1/3 c plus 1 Tbsp) all-purpose flour
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 3/4 tsp kosher salt (Diamond Crystal)
  • 120g granulated sugar
  • 30g light brown sugar
  • 1 large egg, cold
  • 1 large egg yolk, cold
  • 1/2 tsp vanilla extract
  • 100g walnuts, toasted and chopped
  • Flaky salt, for garnish

Method:

  1. In a small saucepan, melt the butter over low heat. You’re not trying to brown it or drive off any moisture, so don’t let it boil — pull it off when there are still a couple unmelted bits left and let the residual heat finish the job.
  2. While the butter is melting, place the espresso powder and 50g of the chopped caramelized white chocolate in a large bowl. Once the butter has melted, pour it over the espresso-chocolate mixture. Whisk until the chocolate has melted. Let cool for about 5 minutes.
  3. Whisk the sugars into the butter until smooth and combined, followed by the egg and egg yolk. Whisk in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Add the dry ingredients to the wet and fold together until just combined. When just a few streaks of flour remain, add the remaining 100g caramelized white chocolate and walnuts. Mix just until evenly distributed. Cover and chill for half an hour, or until firm but not solid.
  5. While the dough is chilling, preheat the oven to 350°F (175°C) with a rack in the middle and line two large baking sheets with parchment paper. Portion the dough into 15 ping-pong sized balls, about 50 grams each. (At this point, the dough balls can be refrigerated for up to 3 days or frozen for longer storage. For best results, bring dough to room temperature before baking — see notes above.) Place the cookies on the prepared baking sheets about 2½ inches apart and sprinkle the tops generously with flaky salt.
  6. Bake the cookies one sheet at a time until the edges are set but the centers are still soft and barely set, 10-11 minutes (the cookies will not brown much). Rotate the sheet in the oven halfway through baking. Cool the cookies on the baking sheets for about 5 minutes, then transfer to a wire rack to cool completely. Store leftovers in an airtight container for up to 3 days.

Linzer cookies

Linzer cookies are one of those classic Christmas cookies I’d never gotten around to making until recently. I love sandwich cookies, but to be honest they can be time-consuming with all the chilling / rolling / stamping / filling. I recommend making them on an afternoon when you don’t have a ton of other baking to do; just throw on your favorite tunes and enjoy the process.

A couple notes:
  • This dough contains a high proportion of nuts, which makes it very delicious but also extremely delicate. I found it easiest to roll between pieces of plastic and chill overnight before cutting and baking. I also recommend using simple cookie cutter shapes (i.e. circles and squares) for best results (I used this set).
  • Linzers are traditionally made with almonds and raspberry jam; I used walnuts because I had a lot on hand and filled them with the ends of jam jars I always have lurking around in the fridge.
  • You can bake these cookies several days in advance (store them at room temperature in an airtight container), but I recommend filling them on the day you plan to serve them as the cookies will gradually soften once they’re filled.
  • If you don’t want to bother rerolling the scraps, you can shape leftover dough into thumbprint cookies instead. Just roll into balls, indent with your thumb or the back of a wooden spoon, and bake until golden. Fill indents with jam once cooled.

Linzer Cookies

Makes about thirty 2-1/2″ sandwich cookies

Ingredients:

  • 105g (scant 1 c) toasted walnuts, chopped
  • 75g granulated sugar
  • 75g light brown sugar
  • 1 teaspoon kosher salt (Diamond Crystal)
  • 281g all purpose flour
  • 225g unsalted butter, cold and cubed
  • 1 large egg plus 1 large egg yolk, cold
  • 2 teaspoons pure vanilla extract
  • 1/2 – 3/4 c jam or preserves
  • Icing sugar, for dusting

Method:

  1. In the bowl of a food processor, combine the walnuts, sugars, and salt. Pulse together until the nuts are finely ground and the mixture is the texture of damp sand.
  2. Add the flour and pulse to combine.
  3. Scatter the butter cubes over the top and pulse until the butter is well incorporated, with no large pieces remaining. Scrape down the sides of the food processor a couple times during this process.
  4. Whisk together the egg, egg yolk, and vanilla. Add to the flour mixture and pulse just until a dough starts to form.
  5. Transfer about half of the dough to a piece of plastic wrap. Pat into a square about an inch thick. Place another piece of plastic wrap on top and roll the dough to about 3/16″. Lift and replace the top piece of plastic occasionally to avoid creases in the dough. Repeat with other half of dough. Slide one sheet of dough onto a baking sheet (still sandwiched between pieces of plastic) and slide the second sheet of dough on top. Refrigerate until cold, about 3 hours or up to 24.
  6. When ready to bake, preheat the oven to 350F and line two large baking sheets with parchment paper. Remove one sheet of dough from the fridge. Peel off the top piece of plastic, invert the dough onto one of the parchment-lined baking sheets, and peel off the other piece of plastic. Use a 2 1/2″ round cookie cutter to punch out as many rounds as possible. Remove the excess dough and set aside. Repeat with the second sheet of dough. Use a small round or other decorative cutter to punch out the centers of half the circles. Reroll and repeat process with dough scraps until you’ve used up all the dough (follow rolling process in step 5, chilling as necessary). If the dough is still firm, proceed straight to baking; otherwise, chill first until firm, about 15 minutes.
  7. Bake sheets one at a time for about 15 minutes, or until cookies are just barely golden on the edges. Cool cookies on the sheet for 5 minutes before transferring to a wire rack to cool completely.
  8. Sift icing sugar over the cookies with the center cutouts. Using a small spoon or offset spatula, spread about a teaspoon of jam on the flat sides of the bottom cookies. Top each with a sugared cookie. Serve immediately, or store in an airtight container between layers of parchment or wax paper until serving. I recommend filling cookies the day you plan to serve them (see notes above).
