Make slow cooker candied cinnamon pecans easily. Sweet, crunchy, and aromatic—perfect for snacking or gifting.
In a medium matte grey ceramic mixing bowl, whisk the large egg white together with the vanilla extract until the surface becomes a glossy, airy foam. Keep the whisk in the bowl when you pause — little streaks of protein foam cling to the tines and tiny bubbles form a velvety halo on top. This frothy, slightly glossy white mixture is what will help the sugar adhere to every nook of the pecan halves, so take a full minute or two to build that stable, slightly pillowy texture.

Gently fold the pecan halves into the bowl so each piece becomes tacky with the egg-white foam, then sprinkle in the granulated sugar, light brown sugar and cinnamon. Stir with a sturdy wooden spoon until the nuts are visibly covered in a grainy, cinnamon-speckled coating — some pecans will show a raw nut brown peek through, others will be fully dusted in sugar. The mixture should look intentionally messy: clusters of sugar clinging to curves and crevices, flecks of brown from the sugar, and a soft sheen from the egg. Keep the same matte grey bowl and the wooden spoon in frame to show continuity.

Spray the inside of a dark ceramic slow cooker basin and transfer the sugared pecans in an even layer. Set to low and let slow, steady heat do its work — after the first hours the sugar will begin to melt and the nuts will darken and take on a toasted amber tone. Thirty minutes before the end, add the small measure of water and fold once more; the water encourages the dissolved sugars to bloom into a glossy, toffee-like glaze that slicks over the pecan surfaces. The result in the cooker should look like overlapping pecan halves in a shallow pool of bubbling, amber sugar syrup that is turning into a sticky, crystallizing glaze. Keep a wooden spoon resting in the basin to show active handling.

Scoop the glossy, caramel-coated pecans onto a wire cooling rack set over the bright white quartz so excess syrup can drip and the sugar can recrystallize. As they cool, the coating becomes grainy-crisp in places and glassy-sticky in others, creating a pleasing contrast of matte toasted brown nut and shiny, crystallized sugar. Spread them out so individual halves are readable, with a few stray grains of sugar and a cinnamon stick or two nearby to hint at flavor. Let them cool completely until the surface is hard and crunchy, ready to snack or package as a gift.
