# What You’ll Need:

→ Sheet Cake

01 - 2.5 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 for fondant adhesion

# Directions:

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 using a stand mixer, cream together sugar and butter until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating thoroughly 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. Trim excess fondant.
11 - Brush fondant lightly with water where desired for adhesion. Dust the surface with pearl luster dust using a dry food-safe brush for a shimmering effect. Optionally brush lightly with a mixture of corn syrup and water. Arrange edible pearls to create Communion motif such as a cross, chalice, or border.
12 - Allow cake to set for 30 minutes before serving.

# Expert Advice:

01 -
  • The cake stays impossibly moist because the ratio of butter to flour is perfectly balanced—no dry crumbles, just tender layers.
  • Pearl fondant transforms a regular sheet cake into something that looks like it came from a professional bakery, but you made it yourself in your own kitchen.
  • It feeds a crowd elegantly without requiring you to bake multiple tiers or stress over intricate piping.
02 -
  • Room temperature ingredients are not optional—they're the difference between a tender, evenly textured cake and one that's dense or has tunnels running through it.
  • Don't overmix the batter once the flour goes in; mix just until you don't see streaks of flour, even if there are small lumps—overmixing develops gluten and makes the cake tough.
  • The cake must be completely cool before you apply buttercream and fondant, or both will slide right off and make you want to start over.
03 -
  • If your buttercream breaks or becomes grainy while you're making it, warm a small bowl in hot water and place your buttercream bowl inside it for a few seconds, then beat it again—the gentle heat usually brings it back together.
  • Invest in a fondant smoother tool; it costs a few dollars and eliminates the need to spend 20 minutes using your hands to smooth out wrinkles and air pockets in the fondant.
  • If you're making this cake more than a few hours before serving, wrap the unfrosted cake layers in plastic wrap and store them at room temperature or wrapped in the refrigerator; frost and decorate a few hours before guests arrive so everything looks fresh.
