Directions

Step 1

Preheat the oven to 325 degrees F.

Step 2

Grease a 12x17-inch half sheet pan, then line it with parchment paper. The pan size is imperative: this batter won’t fit into anything smaller. Likewise, the cake would be too thin if baked in larger pans.

Step 3

Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the 1 1/2 cups of the butter on high speed until smooth and creamy, about 2 minutes.

Step 4

Scrape down the sides and up the bottom of the bowl with a rubber spatula.

Step 5

Add the cream cheese and beat on high speed until completely smooth and combined, about 1 minute.

Step 6

Add the 2 cups of the granulated sugar and beat on high speed until combined, about 1 minute.

Step 7

Add the sour cream and vanilla and beat on high speed until combined and creamy.

Step 8

Scrape down the sides and up the bottom of the bowl with a rubber spatula.

Step 9

On low speed, beat the eggs into the cream mixture, 1 at a time, allowing each egg to fully mix in before adding the next. Be careful not to overmix after the eggs have been added.

Step 10

Once the 6th egg is combined into the mixture, stop the mixer and add the cake flour, baking powder, and salt.

Step 11

Beat on medium speed until just combined, being careful again not to overmix.

Step 12

Fold in the lemon juice.

Step 13

Using a rubber spatula or sturdy whisk, give the batter a final turn to make sure there are no lumps at the bottom of the bowl. The batter should be thick and creamy.

Step 14

Pour or spoon batter evenly into the prepared pan.

Step 15

Carefully bang the pan on the counter once or twice to bring up any air bubbles.

Step 16

Bake until a toothpick inserted into the center comes out completely clean, about 25-30 minutes.

Step 17

Remove the cake from the oven and allow it to cool inside the pan. The cake will shrink down from the sides.

Step 18

Once cool, invert the cake onto a cutting board or on the counter with the long side facing you.

Step 19

With a sharp knife or pizza cutter, slice the cake in half horizontally.

Step 20

Cut each long rectangle into 3 smaller rectangles. You should have 6 rectangles.

Step 21

Very carefully and slowly slice each in half, as if you were making a 1 layer cake a 2 layer cake. You should now have 12 very thin rectangles.

Step 22

With a handheld or stand mixer fitted with a paddle attachment, beat the 3/4 cup of the butter on medium speed until creamy, about 2 minutes.

Step 23

Add the confectioners’ sugar, heavy cream, and vanilla extract.

Step 24

Beat the mixture on low speed for 30 seconds.

Step 25

Increase the mixing speed to high speed and beat for 3 full minutes.

Step 26

Add up to 1/4 cup more confectioners’ sugar if the frosting is too thin or another tablespoon of heavy cream if the frosting is too thick. Add salt to taste if the frosting is too sweet.

Step 27

With a sharp knife, trim the ends off the cake rectangles that touched the pan. They’re a little harder and uneven, which would create lopsided petit fours.

Step 28

Spread the vanilla buttercream in a thick even layer on 4 of the rectangles.

Step 29

Spread both the lemon curd and raspberry jam on 4 of the rectangles. The remaining 4 rectangles are plain because they are the tops. Go a little lighter on the raspberry jam and lemon curd compared to the vanilla buttercream. If there’s too much, it creates a big mess when cutting the petit fours.

Step 30

Place the lemon curd and raspberry jam rectangles on top of the vanilla buttercream rectangles.

Step 31

Layer the plain rectangles on top.

Step 32

Loosely cover each rectangle and chill in the refrigerator for at least 2 hours or freeze for 1 hour. They must be chilled before cutting into tiny petit fours.

Step 33

Once cold, slice each cake rectangle into 12 little squares.

Step 34

Arrange the squares on a baking sheet and chill in the refrigerator or freezer as you melt the white chocolate.

Step 35

Melt the white chocolate and oil together in a double boiler or in the microwave in 20 second increments, stopping and stirring after each until smooth and melted. If it seems too thick, add another drop of oil to thin out.

Step 36

Spoon or drizzle the white chocolate mixture over the petit fours.

Step 37

Top with the garnishes of your choice.

Step 38

Cover and store the petit fours in the refrigerator for up to 5 days, or serve immediately!
