  • 1 package (3.4 oz) Jell-O instant vanilla pudding mix
  • ¼ cup powdered sugar
  • 1 cup whole milk (cold)
  • ½ tub (4 oz) Cool Whip, extra creamy (thawed)

Vanilla & Chocolate Buttercream Frosting

  • ½ cup salted butter (softened at room temperature)
  • ½ cup butter-flavored shortening (room temperature)
  • 1 tsp pure vanilla powder
  • ½ tsp almond extract
  • 3 tbsp heavy whipping cream
  • 3½ – 4 cups powdered sugar

Instructions

  1. Prepare Yellow Cake: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch cake rounds and line the bottoms with parchment paper to prevent sticking.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, salt, and pure vanilla powder until well combined. Set aside.
  3. Cream Butter and Sugar: Using a stand mixer fitted with a paddle attachment, cream the unsalted butter and granulated sugar on medium-high speed until the mixture is pale and fluffy, about 3-5 minutes.
  4. Add Eggs: Reduce the mixer speed and add eggs one at a time, fully incorporating each before adding the next.
  5. Combine Dry and Wet Ingredients: Alternately add the flour mixture and whole milk to the creamed butter mixture, starting and ending with the flour mixture. Mix each addition thoroughly but avoid overmixing.
  6. Bake: Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out mostly clean.
  7. Cool Cakes: Place cakes on a wire rack to cool for a few minutes, then remove from pans and remove parchment. Allow the cakes to cool completely on the wire rack.
  8. Refrigerate Cakes: Wrap the cooled cakes tightly in plastic wrap and refrigerate until ready to level and assemble.
  9. Prepare Vanilla Custard Filling: In a medium bowl, whisk the instant pudding mix and powdered sugar until combined.
  10. Add Milk and Cool Whip: Pour in cold milk and whisk for two minutes until smooth. Fold in spoonfuls of Cool Whip until fully incorporated and lump-free.
  11. Chill Custard: Transfer custard to an airtight container and refrigerate until needed.
  12. Make Vanilla Buttercream: In a stand mixer with paddle attachment, cream together softened salted butter, shortening, and almond extract until smooth.
  13. Add Cream and Sugar: Mix in heavy whipping cream. Then, on low speed, gradually add powdered sugar and pure vanilla powder. Mix for 2-3 minutes until fluffy.
  14. Reserve Portion for Chocolate Frosting: Set aside ¼ of this vanilla buttercream in a small bowl.
  15. Adjust Vanilla Buttercream Consistency: Continue mixing remaining vanilla buttercream, adding powdered sugar or cream to reach the desired texture. Store in an airtight container.
  16. Make Chocolate Buttercream: Return reserved buttercream portion to mixer, add cacao powder, and beat until smooth and spreadable. Add cream if needed. Store separately.
  17. Prepare Ganache: Place chopped bittersweet chocolate in a medium metal bowl. Scald heavy cream by heating until it just begins to simmer, then pour over chocolate.
  18. Melt and Stir Ganache: Cover with plastic wrap and let stand for 2 minutes. Gently stir from center outward until smooth and shiny.
  19. Set Ganache: Place plastic wrap directly on ganache surface and let it cool and thicken overnight at room temperature. Do not refrigerate or stir during setting.
  20. Warm Ganache: Before using, gently stir ganache until smooth and warm slightly in microwave for 5-10 seconds to soften for dripping.
  21. Level Cakes: Use a cake leveler to trim the tops of the cakes to create flat layers.
  22. Assemble First Layer: Affix one cake layer to an 8-inch cake board with a small smear of vanilla buttercream.
  23. Pipe Frosting Border: Place cake on a turntable and pipe a border of vanilla buttercream with Wilton 2A tip around the top edge.
  24. Add Custard Swirl: Pipe a continuous swirl of vanilla custard inside the buttercream border on the first cake layer.
  25. Add Second Cake Layer: Place second cake layer on top of custard filling.
  26. Crumb Coat Cake: Use an offset spatula to coat top and sides of cake with vanilla buttercream and smooth with a pastry scraper to seal crumbs.
  27. Chill Cake: Refrigerate until firm.
  28. Apply Ganache Drip: Transfer slightly warm ganache into a squeeze bottle. Starting just above the cake edge, gently squeeze to create drip effect around the top edge. Pour remaining ganache onto center of cake and spread to edges with an offset spatula.
  29. Chill Again: Return cake to refrigerator to set ganache.
  30. Pipe Buttercream Swirls: Using Wilton 2D tip, pipe chocolate buttercream swirls on top of the ganache.
  31. Pipe Custard Swirls: Fill gaps between chocolate swirls with vanilla custard swirls using Wilton 1M tip.

Notes

  • Room temperature ingredients ensure better mixing and a lighter cake texture.
  • Do not refrigerate ganache while setting as it can cause unwanted texture changes.
  • The cake must be thoroughly chilled before applying ganache drip to prevent melting and running.
  • Adjust buttercream consistency with powdered sugar or cream to achieve desired spreadability.
  • This cake is best assembled the day before serving to allow flavors to meld.
