# What You’ll Need:

→ Sheet Cake

01 - 3 cups all-purpose flour
02 - 2½ teaspoons baking powder
03 - ½ 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 - 1¼ 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
17 - 1 tablespoon light corn syrup
18 - Water as needed for fondant adhesion

# How-To Steps:

01 - Preheat oven to 350°F. Grease a 12x18-inch half-sheet 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, or 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 softened butter until creamy. Gradually add powdered sugar, milk, vanilla extract, 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 your 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. Optionally brush with a mixture of corn syrup and water for added shine.
13 - Arrange edible pearls as desired to create a Communion motif such as a cross, chalice, or decorative border.
14 - Allow cake to set for 30 minutes before serving.

# Expert Tips:

01 -
  • The cake stays impossibly moist for days, which means you can bake ahead without any stress.
  • Fondant transforms a simple sheet cake into something that feels like a professional bakery creation, impressing everyone who sees it.
  • The buttercream base makes the fondant stick beautifully, so you won't have any sliding or bubbling disasters.
02 -
  • Fondant hates humidity—if your kitchen is damp or it's a rainy day, work quickly and keep unused fondant wrapped in plastic until the moment you need it.
  • The buttercream layer isn't just decoration; it's essential because fondant alone slides right off cake and makes a mess, but a thin, smooth buttercream acts as its perfect anchor.
03 -
  • Always use room temperature eggs and softened butter—they cream together into something fluffy and light that cold ingredients simply cannot achieve.
  • The alternating method of adding flour and milk prevents overmixing, which is the enemy of tender cakes, so mix until ingredients are just combined and then stop, even if there are tiny streaks of flour visible.
