# What You 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, optional
17 - 1 tablespoon light corn syrup
18 - Water for fondant adhesion

# How To Make It:

01 - Preheat oven to 350°F. Grease a 12x18-inch 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 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. Dust the surface with pearl luster dust using a dry food-safe brush for a shimmering effect.
12 - Lightly brush with a mixture of corn syrup and water for added shine. Arrange edible pearls as desired to create a Communion motif such as a cross, chalice, or border.
13 - Allow cake to set for 30 minutes before serving.

# Expert Tips:

01 -
  • The cake stays impossibly moist even days later, thanks to the milk-to-flour ratio that took me three tries to get right.
  • Fondant work looks intimidating until you realize it's just patient smoothing and a little water—suddenly you're decorating like a professional.
  • This is one of those desserts that makes people gasp when they see it, then actually enjoy eating it.
02 -
  • Fondant is sensitive to humidity—if your kitchen is damp, the fondant will get sticky; if it's dry, it'll crack; room temperature around 68-72°F is the sweet spot.
  • That buttercream layer under the fondant isn't just decoration—it's insulation that keeps the cake from drying out and creates a smooth surface that makes fondant look professional.
  • Luster dust is beautiful only when applied with a completely dry brush to completely dry fondant—any moisture turns it into paint instead of shimmer.
03 -
  • Bake the cake a day ahead if possible—it's easier to work with when it's completely set, and the flavors actually deepen overnight.
  • Room temperature ingredients really do matter; take the five minutes to let everything sit out rather than rushing into mixing.
  • A fondant smoother (or even a small offset spatula) eliminates fingerprints and creates that professional finish that makes people think this came from a bakery.
