# What You'll Need:

→ Sheet Cake

01 - 3 cups all-purpose flour
02 - 2.5 teaspoons baking powder
03 - 0.5 teaspoon salt
04 - 2 cups granulated sugar
05 - 1 cup unsalted butter, softened
06 - 4 large eggs, room temperature
07 - 1 tablespoon pure vanilla extract
08 - 1.25 cups whole milk

→ Buttercream

09 - 1 cup unsalted butter, softened
10 - 4 cups powdered sugar, sifted
11 - 2 tablespoons whole milk
12 - 1 teaspoon vanilla extract
13 - Pinch of salt

→ Pearl Fondant Decoration

14 - 2 pounds white ready-to-roll fondant
15 - Pearl luster dust, food-safe
16 - Edible pearls or sugar pearls, optional
17 - 1 tablespoon light corn syrup, optional
18 - Water as needed for fondant adhesion

# Step-by-Step Directions:

01 - Preheat oven to 350°F. Grease a 12x18-inch sheet cake pan and line with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
03 - In a large bowl or stand mixer, cream together sugar and butter until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
05 - Alternately add flour mixture and milk in three additions, beginning and ending with flour. Mix until just combined without overmixing.
06 - Pour batter into prepared pan and smooth the top. Bake for 30-35 minutes until a toothpick inserted in the center comes out clean.
07 - Remove cake from oven and cool in pan for 10 minutes. Turn out onto a wire rack and cool completely.
08 - Beat butter until creamy. Gradually add powdered sugar, milk, vanilla, and salt. Beat until fluffy and smooth.
09 - Once cake is completely cool, spread a thin, even layer of buttercream over the entire surface and sides.
10 - Roll out fondant on a surface lightly dusted with powdered sugar to approximately 1/8-inch thickness. Drape fondant over cake, smoothing with hands or a fondant smoother.
11 - Trim excess fondant. Brush lightly with water where you wish to adhere edible pearls or decorations.
12 - Dust the surface with pearl luster dust using a dry food-safe brush for a shimmering effect. Lightly brush with a mixture of corn syrup and water for added shine, if desired. Arrange edible pearls as desired to create a Communion motif.
13 - Let cake set for 30 minutes before serving.

# Expert Hints:

01 -
  • The cake stays impossibly moist for days, and that buttercream layer keeps the fondant from sliding around like it has a mind of its own.
  • You'll feel like a professional pastry chef when you smooth that fondant and dust it with pearl, even if this is your first fancy cake.
  • Twenty servings means you can feed a crowd without spending all morning in the kitchen, which honestly feels like a small miracle.
02 -
  • Fondant hates humidity and warmth—if your kitchen is steamy or hot, your fondant will get sticky and refuse to cooperate, so work in a cool space and have powdered sugar nearby for dusting.
  • The buttercream layer between cake and fondant is not optional; it's your insurance policy against a dry cake and your adhesive for keeping everything in place.
  • Room temperature eggs and butter are not suggestions—cold ingredients won't blend properly and you'll end up with a grainy, separated batter that bakes unevenly.
03 -
  • If your fondant starts cracking as you drape it, don't panic—dip your fingers in water and smooth the cracks closed, then dust with powdered sugar to hide any evidence.
  • Pearl luster dust applied with a dry brush gives a more sophisticated shimmer than anything you can buy pre-decorated, and it makes guests think you went to pastry school.
