Instructions
Preheat Oven & Prepare Pan
Preheat the oven to 350°F (177°C). Line a 12×17‑inch baking sheet with parchment paper.
Time: PT5M
Temperature: 350°F
Combine Dry Ingredients
Measure 3 cups (360 g) all‑purpose flour, 1¼ teaspoons baking powder, and ½ teaspoon salt into a bowl. Whisk briefly to distribute.
Time: PT5M
Cream Butter and Cream Cheese
In the stand mixer fitted with the whisk attachment, add 1½ cups (339 g) room‑temperature unsalted butter and 8 oz (226 g) softened cream cheese. Cream on medium speed until smooth, about 3–4 minutes.
Time: PT5M
Incorporate Sugar
Add 2 cups (400 g) granulated sugar to the butter‑cream cheese mixture. Beat on high for about 2 minutes until light and fluffy.
Time: PT2M
Add Eggs and Vanilla
Crack 5 eggs into a separate bowl (no shells). Add 2 teaspoons vanilla extract. With the mixer on high, add the eggs one at a time, mixing after each addition. Scrape the bowl frequently.
Time: PT5M
Combine Wet and Dry Mixtures
With the mixer on its lowest setting, add the dry flour mixture and ½ cup milk in three alternating batches, beginning and ending with the flour. Finish mixing by hand until just combined; do not overmix.
Time: PT5M
Spread Batter & Release Bubbles
Transfer the batter to the prepared sheet. Use a spatula to spread it evenly to about ½‑inch thickness. Tap the sheet gently on the counter to pop large air bubbles.
Time: PT3M
Bake the Cake
Bake for 26 minutes, or until the top is lightly golden and the cake springs back when lightly pressed. Listen for a quiet, faint crackle; louder crackling means it needs another minute.
Time: PT26M
Temperature: 350°F
Cool & Cut the Cake
Allow the cake to cool on the rack for 10 minutes. Remove parchment, then using a sharp serrated knife, cut the cake in half horizontally, then each half into strips, and finally into 1‑ to 1¼‑inch squares.
Time: PT10M
Prepare Vanilla Buttercream
In a clean bowl, beat 1 cup (227 g) softened unsalted butter until creamy (≈2 min). Gradually add 4 cups (≈480 g) sifted powdered sugar, mixing on low. Add 4 Tbsp heavy cream, ¼ tsp salt, and 2 tsp vanilla; beat on high for 3 minutes until light and fluffy.
Time: PT10M
Assemble Cake Sandwiches
Lay half of the cake squares on a wire rack. Using a cookie scoop, spread a thin layer of buttercream on each piece, then a dollop of raspberry jam, and top with another cake square. Press gently to create a sandwich.
Time: PT10M
Freeze Sandwiches
Place the assembled sandwiches on a tray and freeze for 20 minutes to firm the filling.
Time: PT20M
Trim & Freeze Cubes
Using a sharp knife, trim any uneven edges of the frozen sandwiches. Return the trimmed cubes to the freezer until completely solid.
Time: PT5M
Make White Chocolate Fondant
Chop 8 oz white chocolate and melt it in a heatproof bowl over simmering water (double boiler) until smooth. Remove from heat. In a separate bowl, sift 3½ cups (420 g) powdered sugar. Add ⅓ cup hot water and ¼ cup light corn syrup, whisk gently, then fold the mixture into the melted chocolate until glossy and pourable.
Time: PT14M
Dip Cubes in Fondant
Using a large fork, hold each frozen cube and spoon the fondant over it, rotating to coat all sides. Tap the fork to release excess fondant. Pop any surface bubbles with a toothpick.
Time: PT10M
Set Fondant
Arrange the coated cubes on a wire rack over a baking sheet. Let them sit at room temperature for about 1 hour until the fondant firms.
Time: PT60M
Pipe Buttercream Roses
Fit a small 101‑type piping tip with a pastry bag. Fill with leftover buttercream (color as desired). Pipe a tiny rose on the center of each fondant‑coated cube, adding a leaf or two if you like.
Time: PT10M
