Ingredients

Equipment Needed

• •Stand mixer or hand mixer
• •Heavy-bottomed saucepan (2-quart)
• •Rimmed baking sheets
• •Wire cooling rack
• •Rounded teaspoon measure (for pressing wells)

Instructions

1. 1

   Cream butter and sugars

   In a large bowl, beat the softened butter with the powdered sugar and light brown sugar using a stand mixer or hand mixer on medium speed. Work it for a full three minutes until the mixture turns pale and fluffy, scraping down the sides twice. This step builds air into your dough, and that air gives you tender cookies. You want butter that yields to gentle pressure but still holds its shape. Too cold and it won't cream. Too soft and your cookies spread flat.

   Set your butter out two hours before baking. It should feel like firm clay, not soft like mayonnaise.
2. 2

   Add egg and flavorings

   Beat in the egg yolk, vanilla, and salt until everything comes together smooth and creamy, about thirty seconds. We use just the yolk here because it adds richness without extra moisture. The white would make these cookies puff and crack, and we want smooth little pillows with clean thumbprint wells.

3. 3

   Incorporate flour gently

   Add the flour in two additions, mixing on low speed just until the flour disappears after each. Stop the moment you see no more dry streaks. This dough should be soft but not sticky, holding together when you press it. Overwork it now and you'll have tough cookies that fight back when you bite them.

4. 4

   Chill the dough

   Wrap the dough in plastic and refrigerate for at least thirty minutes. Cold dough holds its shape better and the thumbprints stay put during baking. You can chill this overnight if you're working ahead.

   If your kitchen runs warm, chill the dough for a full hour. Louisiana summers taught me that lesson the hard way.
5. 5

   Shape the cookies

   Preheat your oven to 350°F. Line baking sheets with parchment paper. Roll the dough into one-inch balls, about a tablespoon each, and place them two inches apart on your prepared sheets. Use your thumb or the back of a rounded teaspoon measure to press a deep well into the center of each ball. Press firmly but don't go all the way through. The wells will shallow slightly during baking, so make them deeper than you think necessary.

6. 6

   Bake until set

   Bake for twelve to fourteen minutes, rotating the pan halfway through. The cookies are done when the edges turn the palest gold and the tops look dry and set, but not browned. These are shortbread cookies, and browning means you've gone too far. Remove from the oven and immediately re-press the thumbprints with your spoon if they've puffed up. Let cool on the baking sheet for five minutes, then transfer to a wire rack.

7. 7

   Make the praline filling

   While the cookies cool, melt the butter in a heavy-bottomed saucepan over medium heat. Add the dark brown sugar, cream, and salt. Stir constantly until the sugar dissolves completely, then let the mixture come to a gentle boil. Cook for two minutes without stirring, watching it bubble and deepen in color. The smell should hit you: buttery, caramelized, pure Louisiana candy shop.

   Use a heavy pan. Thin pans create hot spots that burn your sugar before the rest of it melts.
8. 8

   Finish the praline

   Remove the pan from heat and stir in the chopped pecans and vanilla. The mixture will bubble up when you add the vanilla, so keep your face back. Let the praline cool for about five minutes, stirring occasionally. It should thicken to the consistency of warm honey, thick enough to mound in the thumbprints without running over the edges.

9. 9

   Fill and top the cookies

   Spoon about a teaspoon of the warm praline filling into each thumbprint well, letting it mound slightly in the center. Work quickly before the filling sets. Press a pecan half gently into the top of each filled cookie. Let the cookies sit at room temperature until the praline firms up completely, about thirty minutes. The filling should be tacky but no longer liquid.

Chef Tips

• •Louisiana pecans have the sweetest, most buttery flavor. If you can find them, use them. Texas and Georgia pecans work fine, but there's something special about pecans from the Gulf Coast.
• •The praline filling thickens as it cools. If it gets too thick to spoon, warm it gently over low heat. If it's too thin, let it sit another minute or two.
• •Toast your chopped pecans in a dry skillet for three minutes before adding them to the praline. This extra step deepens the flavor considerably.
• •These cookies stack beautifully in tins for gift-giving. Layer them between sheets of wax paper to prevent sticking.
• •For a touch of Louisiana heat, add a tiny pinch of cayenne to the praline filling. Not enough to taste spicy, just enough to make people wonder what makes these so addictive.

Advance Preparation

• •Cookie dough can be refrigerated for up to three days before shaping and baking.
• •Shaped, unbaked cookies can be frozen on a baking sheet, then transferred to a freezer bag for up to two months. Bake directly from frozen, adding two minutes to baking time.
• •Praline filling can be made up to one week ahead and stored in an airtight container at room temperature. Warm gently before using.
• •Finished cookies keep in an airtight container at room temperature for up to one week, or frozen for up to two months.
