Step by Step Guide: How I Bake This Sheet Cake
I always start with prepping the ingredients. My trick? I zest the lemon directly into the sugar bowl first it infuses the sugar with oils and gives a more fragrant punch when mixing.
Ingredients
2½ cups all purpose flour
1 cup sugar
1 tbsp baking powder
½ tsp salt
1 cup milk
½ cup butter (softened)
3 eggs
2 tbsp lemon juice
1 tbsp lemon zest
1 tsp vanilla extract
Instructions
Prep the oven and pan
Preheat your oven to 350°F (175°C).
Grease a 9×13 inch sheet pan or line it with parchment for easier cleanup.
Mix the dry ingredients
In a medium bowl, whisk together the flour, baking powder, and salt.
Set aside it’s important these are fully blended to avoid uneven rising.
Cream the wet ingredients
In a large bowl, beat the softened butter with sugar until light and fluffy about 2 minutes using a hand mixer.
Add eggs one at a time, mixing well after each. Don’t rush this step, eggs bring the structure.
Stir in the milk, lemon juice, lemon zest, and vanilla extract. The batter may look slightly curdled don’t worry, it’s the lemon reacting to the dairy and it smooths out when you add the flour.
Bring it all together
Gradually add the dry mix into the wet mix, stirring until just combined. Overmixing can toughen the cake, so stop once no dry streaks remain.
Bake it
Pour the batter into your prepared pan and spread evenly.
Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean.
Let the cake cool in the pan for at least 10 minutes before slicing.
Chef’s Real Life Prep Notes
Here’s the truth the first time I baked this sheet cake, I got distracted prepping glaze for another dessert. I accidentally left the batter sitting out for 15 minutes before baking. The cake still came out soft and golden. That’s when I knew this recipe was forgiving.
