Add 1 ½ cups of the flour to the mixing bowl. Sprinkle the baking powder and salt over top of the flour.
2 ½ cups all-purpose flour, 2 ½ teaspoons baking powder, ½ teaspoon salt
Mix just until the flour is incorporated.
With the mixer on low, add milk.
¾ cup milk
Add remaining cup of flour and mix just until incorporated. I often stop mixing and use my silicone spatula to finish folding the flour into the batter.
Add batter to a 9x13 inch cake pan sprayed with a nonstick spray.
Bake in a preheated 350°F oven for 30-35 minutes until the cake is fully cooked.
Remove from oven and allow cake to cool slightly.
Lemon Curd
Place egg yolks, lemon juice, lemon zest and sugar in a bowl of a double boiler or in a metal bowl. Whisk together.
4 egg yolks, ½ cup granulated sugar, 1 zest from 2 lemons, ⅓ cup lemon juice
Place over a pot with a small amount of simmering water. Make certain the bowl is not touching the water. Whisk mixture until it begins to thicken.
Remove from heat and whisk in butter a few cubes at a time making certain it is fully incorporated before adding additional butter.
4 tablespoons salted butter
Whipped Cream
Whip cream together until soft peaks are formed. Add sugar and stir.
2 cups heavy whipping cream, 2 tablespoons granulated sugar
Assembling the Cake
Poke holes in cake using the round handle of a wooden spoon.
Spread lemon curd over the top of the cake.
Add whipped cream and cover surface of cake.
Refrigerate, uncovered for at least 3 hours before serving. If serving beyond 3-4 hours, cover with plastic wrap and keep in refrigerator
Notes
When making the cake, use room-temperature ingredients.
Use the fluff and scoop method when measuring flour to help prevent over-compacting the flour.
Stop and scrape down the sides of the mixing bowl to make certain everything is well-mixed.
Once you add the flour, don't overmix. Stir just until everything comes together.
Keep holes in cake about 2-3 inches apart. Too close and your cake may not hold together when serving.
If you like a sweeter whipped cream, add additional sugar.
It is okay if the cake is still warm when you add the lemon curd and the whipped cream.
If your curd has lumps, press it through a fine-meshed sieve to remove the lumps.
Cake can be refrigerated for up to 4-5 days.
Nutritional value is figure with the cake cut into 12 pieces.
