1. Preheat your oven to 350°F and grease and flour a 9-inch round cake pan really well—or line the bottom with parchment paper for extra insurance.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this aside—having it ready makes everything smoother.
3. In a large mixing bowl, cream the butter and sugar together until light and fluffy—about 3-4 minutes with a mixer. This step is crucial for texture, so don’t rush it.
4. Beat in those eggs, one at a time, making sure each one is fully incorporated before adding the next. Stir in the vanilla extract, lemon zest, and lemon juice. The mixture might look slightly curdled—that’s normal!
5. Now here’s the key: gradually mix in the dry ingredients, alternating with the buttermilk, until just combined. Start and end with dry ingredients (dry, buttermilk, dry, buttermilk, dry). Mix until just combined—a few small lumps are totally fine.
6. Dice your strawberries into small pieces (about the size of chocolate chips), then pat them gently with paper towels. Gently fold in the diced strawberries until they’re evenly distributed. Don’t overmix—just fold until incorporated.
7. Pour the batter into your prepared cake pan and smooth the top with a spatula. The batter will smell absolutely incredible.
8. Bake for 30-35 minutes, but start checking at 28 minutes. You want a toothpick inserted in the center to come out clean or with just a crumb or two—not wet batter.
9. Let the cake cool in the pan for 10 minutes (it needs this time to firm up), then carefully transfer to a wire rack to cool completely.
10. Slice and serve plain, or drizzle with a lemon glaze or top with fresh strawberries for extra pretty presentation!

Notes:

• Zest the lemons before juicing them—it’s way easier that way.
• Pat those strawberries dry to prevent pink-tinged batter and soggy spots.
• Don’t overmix once you add the flour—mix until you barely see the last streak of flour disappearing.
• Every oven runs differently, so trust your toothpick test over exact timing.
• The mixture might look slightly curdled after adding lemon juice—don’t worry, it’ll come together!

Storage Tips:

• Keep covered at room temperature for up to 3 days—it stays incredibly moist thanks to the buttermilk.
• Individual wrapped slices freeze beautifully for up to 3 months.
• Don’t refrigerate unless your kitchen is really warm—it dries out the cake.
• Wait to add any glaze or toppings until right before serving for best presentation.
