# What You 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

# How To Make It:

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 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, 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. For added shine, lightly brush with a mixture of corn syrup and water if desired. Arrange edible pearls as desired to create a Communion motif such as a cross, chalice, or border.
13 - Let cake set for 30 minutes before serving.

# Expert Tips:

01 -
  • The cake stays impossibly moist for days, which means you can bake it ahead without stress eating away your celebration morning.
  • Fondant does the heavy lifting visually—your kitchen effort feels like you conjured magic, but it's really just patient smoothing and a little shimmer.
  • This isn't a recipe that demands perfection; subtle imperfections in the fondant drape actually look more elegant and honest.
02 -
  • Fondant hates humidity like I hate waiting rooms; if your kitchen is steamy or rainy, it will weep and stick to itself, so work in the coolest, driest part of your day.
  • Don't try to apply fondant to a warm cake—it will slide around and tear, no matter how gentle you are; this is the one rule I learned by failing spectacularly.
03 -
  • Keep a small spray bottle of water nearby when applying fondant; the tiniest mist helps it stick to itself without making everything soggy.
  • Buy extra fondant and luster dust so you can practice rolling and dusting on a scrap before you commit to the actual cake.
