📖 Instructions

1. Preheat your oven to 350°F (175°C). Seriously, don't skip this step! It helps the cake bake evenly from the start. Grease and flour a 9-inch bundt pan, or a 9x5 inch loaf pan, or a 8x8 inch square baking dish. Make sure every crevice is coated; it's the worst when your beautiful cake sticks!
2. In a large mixing bowl, zest your lemons. You want about 1 tablespoon of finely grated zest. Don't press too hard, or you'll get the bitter white pith. Then, squeeze out 1/4 cup of fresh lemon juice from those zested lemons. Set both aside.
3. In another medium bowl, whisk together your dry ingredients: 1 1/2 cups (190g) all-purpose flour, 1 1/2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/4 teaspoon salt. Sifting isn't strictly necessary, but it helps ensure a lighter texture, so if you have a sifter, go for it!
4. In the large bowl with the lemon zest, add 1 cup (200g) granulated sugar. Use your fingers to rub the lemon zest into the sugar. This step is super important as it releases the lemon oils and infuses the sugar with incredible aroma and flavor. You'll actually smell the difference!
5. To the lemon sugar, add 1/2 cup (113g) unsalted butter, softened to room temperature. Beat with an electric mixer on medium speed for about 3-4 minutes, until the mixture is light, fluffy, and pale yellow. Scrape down the sides of the bowl often.
6. Beat in 2 large eggs, one at a time. Make sure each egg is fully incorporated before adding the next. The batter might look a little curdled at this point, but don't fret; it'll come together. Add 1 teaspoon of pure vanilla extract now.
7. With the mixer on low speed, gradually add about one-third of the dry ingredient mixture to the wet ingredients. Mix just until combined. Then, add half of the 1 cup (240g) plain Greek yogurt (full-fat works best for moisture!), mix just until smooth. Repeat with another third of the dry ingredients, then the remaining yogurt, and finally the last third of the dry ingredients. Remember, mix only until just combined; overmixing can lead to a tough cake.
8. Gently fold in the 1/4 cup fresh lemon juice you set aside earlier. Don't be too aggressive; just incorporate it until no streaks remain. The batter should be smooth and luscious.
9. Pour the cake batter into your prepared pan. Use a spatula to smooth the top. Give the pan a gentle tap on the counter a few times to release any large air bubbles.
10. Bake for 35-45 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. If using a bundt pan, it might take a bit longer, up to 50-60 minutes. Keep an eye on it! Oven temperatures vary, so your bake time might differ slightly.
11. Once baked, remove the cake from the oven and let it cool in the pan on a wire rack for about 10-15 minutes. This cooling time in the pan helps the cake firm up and prevents it from breaking when you invert it.
12. After cooling slightly, carefully invert the cake onto the wire rack to cool completely. If you’re making a simple lemon glaze (totally recommended!), prepare it while the cake cools. Just whisk together 1 cup powdered sugar with 2-3 tablespoons of fresh lemon juice until smooth. Drizzle it over the completely cooled cake. Slice and enjoy your light, lemony masterpiece!
13. Store any leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. It actually tastes even better the next day, you know? The flavors really get a chance to meld.
