# What You Need:

→ For the 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

→ For the 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

→ For the 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 as needed for fondant adhesion

# Directions:

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 to 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 and smooth with hands or a fondant smoother.
11 - Trim excess fondant. Brush lightly with water where you wish to adhere 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. Arrange edible pearls as desired to create a Communion motif.
13 - Allow cake to set for 30 minutes before serving.

# Expert Advice:

01 -
  • The cake itself is impossibly tender and stays moist for days, so you're not wrestling with a crumbly base while decorating.
  • Pearl fondant transforms a simple sheet cake into something that photographs like a professional bakery creation, but feels personal and handmade.
  • It actually tastes good underneath all that elegance—no cardboard cake here, just real butter and vanilla.
02 -
  • Room temperature ingredients are not a suggestion—they're the difference between a tender, emulsified batter and a curdled, dense mess that bakes into disappointment.
  • If your fondant tears or cracks while you're smoothing it, don't panic; a small pinch of water on your fingertip will seal minor tears, and you can always cover problem spots with edible pearls.
03 -
  • Use a fondant smoother or even the flat of your hand to gently press out air bubbles and wrinkles as you drape the fondant—patient, gentle pressure works better than force.
  • The buttercream layer under the fondant isn't just decorative; it's functional, creating a barrier between the moisture in the cake and the fondant so the whole thing stays stable and doesn't get soggy.
