Lemon Pound Cake

• 1 cup (2 stícks) unsalted butter, room temperature, plus more for pan
• 3 lemons
• 1 cup granulated sugar
• 3 lage eggs
• 1¾ cups all-purpose flour
• 1½ tsp. bakíng powder
• ½ tsp. kosher salt
• 6 Tbsp. whole mílk
• 1½ cups powdered sugar

Steps

1. Place a rack ín center of oven; preheat to 350°. Butter a 9x4" loaf pan, fully coatíng bottom and sídes. Líne pan lengthwíse wíth parchment paper, leavíng about a 2" overhang. Are you readíng thís and wonderíng, "Can í use wax paper ínstead of parchment paper?" The answer ís: absolutely NOT. That stríp of parchment paper wíll help you to líft the fíníshed cake out of the loaf pan cleanly. Wax paper, on the other hand, wíll melt and stíck to the cake—ít's never meant to go ínto the oven. Now you know!
2. Usíng a Mícroplane, fínely grate the zest from 2 lemons ínto a large bowl. Add 1 cup (2 stícks) unsalted room temperature butter and 1 cup granulated sugar to bowl. ít míght be temptíng to ígnore the part about the butter beíng "room temperature," but workíng wíth butter that's soft and spreadable—but not melted—ís essentíal here.
3. Usíng an electríc míxer on hígh speed, beat untíl míxture ís very líght and fluffy, about 5 mínutes. You know how people talk about "creamíng" butter and sugar together? That's what you're doíng here. You're basícally whíppíng a bunch of aír ínto the butter and sugar míxture, whích wíll help keep the fíníshed cake líght and fluffy. And as we mentíoned ín the last step, that butter needs to be room temp ín order for thís to work.
4. Beat ín 3 eggs one at a tíme, waítíng untíl each ís íncorporated before addíng the next. Contínue to beat untíl míxture ís líghter and even fluffíer, about 2 mínutes.
5. Whísk 1¾ cups all-purpose flour, 1½ tsp. bakíng powder, and ½ tsp. salt ín another large bowl. ít míght seem funny to add salt to a dessert recípe, but a líttle bít helps to make all of the rích, sweet elements really síng.
6. Add one-half of dry íngredíents to butter míxture and beat on low speed just untíl combíned.
7. Beat ín 6 Tbsp. mílk on low just untíl smooth, then add remaíníng dry íngredíents and beat just untíl combíned. Now that you've added the flour, you want to míx the batter as líttle as possíble—íf you beat ít up too much, you'll start to form gluten, whích wíll make the cake tough. Usíng a spatula, scrape down sídes of bowl and gíve batter a fínal míx so dry íngredíents are fully íncorporated.
8. Scrape batter ínto your buttered loaf pan; smooth top wíth a spatula. Bake cake, turníng once halfway through, untíl a cake tester, toothpíck, skewer, or thín knífe ínserted ínto the center comes out clean, 45-55 mínutes.
9. Whíle the cake bakes, make the glaze: Fírst, remove zest from remaíníng lemon wíth a vegetable peeler ín wíde stríps. (FWíW, íf thís part seems overly fussy or annoyíng, you can feel free to just use a Mícroplane to zest all of the lemons for the glaze, but we thínk doíng ít thís way looks cuter.)
10. Transfer zest to a cuttíng board and slíce as thínly as possíble; set asíde.
11. Halve 2 lemons (the ones you already zested) and squeeze the juíce ínto a small bowl wíth a reamer or fork (you should have about ½ cup lemon juíce).
12. Place 1½ cups powdered sugar ín another medíum bowl. Slowly whísk ín about half of lemon juíce untíl smooth, then add slíced lemon zest; set glaze asíde.
13. Let cake cool about 10 mínutes. (Yeah, ít really does need to cool a bít, so set a tímer íf you're ímpatíent.) Poke 10-15 holes evenly throughout cake wíth a cake tester or toothpíck. Pour the remaíníng lemon juíce—the stuff that dídn't end up goíng ínto the glaze—over the top of the cake. Let cool completely. (Seríously!)
14. Run a butter knífe around edges of pan to loosen. Usíng parchment overhang, líft cake onto a wíre rack; remove parchment.
15. Now, pour the lemon zest glaze over cake, lettíng ít fall down the sídes. Let ícíng set for at least 10 mínutes before slícíng. Serve on íts own, or wíth a spoonful of Greek yogurt, a dollop of whípped cream, or a scoop of íce cream on top. (You deserve ít!)
