Cake Instructions

  • *Note* It's very important that all your ingredients are room temp or even a little warm (eggs, milk, butter etc) Or your cake batter could curdle and result in a fallen cake.
    Pre-heat oven to 335ºF. Prep two 8"x2" cake pans or three 6"x2" cake pans with cake goop or other preferred pan release.
  • Combine your flour, baking powder & salt and set aside
    Combine your milk, oil and vanilla extract and set aside. 
  • Place butter into the bowl of your stand mixer and cream until smooth. Sprinkle in your sugar with the paddle attachment and mix on medium until mixture is light and fluffy and white.
  • Add in egg whites one at a time (roughly) and let fully combine after each addition before adding the next. 
  • Add in 1/3 of your dry ingredients and let combine. Add in 1/2 of your liquids, then dry, then liquids and the rest of your dry. Let mix until just combined. 
  • Fold in your confetti or jimmy sprinkles. Don't over mix. 
  • Add batter into prepared cake pans. sprinkle more sprinkles on top of the cake batter if desired. bake at 335 degrees F for 30-35 minutes or until a toothpick comes out clean when poked in the center. 
  • Let cool ten minutes then turn out cakes onto a cooling rack. Wrap warm and place into the freezer to flash chill. This locks in the moisture. Once cool but not frozen you can then trim off the brown edges of your cakes and frost as desired. 

Water Ganache Instructions

  • Melt chocolate in microwave or in a glass bowl over a pot of simmering water (bane marie) and add in water. Whisk until combined. Add food coloring if desired. Let cool to 90 degrees (Should feel slightly cool to the touch but still liquid) and drip over your frosted and chilled cake. 

Easy Buttercream Instructions

  • Place egg whites and powdered sugar in a mixing bowl with the whisk attachment. Whisk to combine. Add in butter in small chunks then vanilla and salt. Whip on high until light and fluffy and white. Optional: switch to the paddle attachment and mix on low for 15-20 minutes until all air bubbles are gone. 
  • Optional: switch to paddle attachment and let mix on low for 15 minutes to get all the air bubbles out. Frost cake as desired.
