Cook Lemon Buttermilk Cupcakes Like This

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners to prepare for baking.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, cornmeal, baking powder, baking soda, and kosher salt. Set aside.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, beat the room temperature butter and granulated sugar together using an electric mixer until the mixture is light and fluffy, about 3-4 minutes.
Step 4: Add the Eggs and Flavorings
Add the eggs and egg yolk one at a time, mixing well after each addition. Then, mix in the lemon zest, lemon juice, and vanilla extract until fully incorporated.
Step 5: Combine Wet and Dry Ingredients
Alternate adding the dry ingredient mixture and the buttermilk to the butter mixture. Start with a third of the dry ingredients, mix until just combined, then add half of the buttermilk. Continue this process until all ingredients are combined, making sure not to overmix.
Step 6: Fill the Cupcake Liners
Spoon the batter into the prepared cupcake liners, filling each about two-thirds full to allow room for rising.
Step 7: Bake
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
Step 8: Cool the Cupcakes
Once baked, remove the cupcakes from the oven and let them cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
Step 9: Prepare the Glaze
In a small bowl, mix the sifted powdered sugar with the lemon juice until smooth. If desired, add food coloring to achieve the perfect shade.
Step 10: Glaze the Cupcakes
Once the cupcakes are completely cool, drizzle the glaze over the tops or dip them into the glaze for a more immersive lemon experience!
In-Season Flavor Ideas

- Incorporate a hint of lavender for a unique floral flavor.
- Use lime juice and zest instead of lemon for a different citrus profile.

Flavor Logic
The bright citrus flavor of lemon beautifully balances the richness of butter and sugar, creating a cupcake that is both refreshing and indulgent. Buttermilk adds tenderness to the crumb, making each bite melt in your mouth. The cornmeal adds a subtle texture that contrasts with the smoothness of the cupcake while enhancing the overall flavor profile. Together, these ingredients create a harmonious blend that delights the palate.

To store your Lemon Buttermilk Cupcakes, keep them in an airtight container at room temperature for up to three days.

Lemon Buttermilk Cupcakes FAQs
Can I substitute the buttermilk in this recipe?
Yes! If you don’t have buttermilk on hand, you can make a substitute by mixing 1/2 cup of milk with 1/2 tablespoon of vinegar or lemon juice. Let it sit for 5 minutes before using it in the recipe.
Can I make these cupcakes ahead of time?
Absolutely! These cupcakes can be baked a day in advance. Just store them in an airtight container at room temperature, and glaze them right before serving for the best texture.
