Boozy Chocolate Skull Cake with Strawberry Jello Brain and Red Velvet blood sauce - A gruesome yet delicious Halloween Cake! Melt the white chocolate skull to reveal the secret jello brain hidden inside! This cake requires 2 days to make since you need refrigeration time as well. PLEASE first read the recipe in full, so you can plan ahead.
Preheat oven to 300°F. Brush the skull pan generously with melted butter and dust it with black cocoa powder. Make sure to butter and dust the whole skull pan. Set aside until the cake batter is ready.
Place the melted butter, oil, sugar, eggs, milk and vanilla extract in a large bowl. Whisk until everything is mixed together well. If you used dutch cocoa, add a few drops of black food coloring to make the cake darker in color. Set aside.
In a separate bowl, sift the black cocoa, flour, baking powder together. Add the salt and mix until well combined.
Divide the cake batter into the two prepared skull pan cavities (about ¾ of the way up in each pan). Bake in preheated oven for 45 - 55 minutes, until an inserted toothpick comes out clean.
Remove the cake from the oven and let it cool down slightly. Turn the cake out on to a cooling rack while it’s still warm and let it cool down completely.
Trim the tops of the cake to remove the top crust. Crumble the crust into cake crumbs and mix it with 1 - 2 tbsp of ganache or frosting to make cake pop dough. This will be used to shape the cake base and the skull cap crown.
Place the sugar, water and vanilla in a pan. Heat over medium high heat and stir to dissolve the water. Bring it to a boil and boil for about a minute or two. Remove from the heat and let the syrup cool down. Stir in the bourbon. Pour the syrup into a squeeze bottle, so that it'll be easier to use.
Allow the ganache to cool down until it's thick enough to spread. Use immediately, or reheat gently if it set hard again.
Stir until the candy melts are completely melted, and slightly cooled down.
Add the popping candy and gently stir to mix it in.
Coat the top of a balloon with the white candy melts - like how you'd create a candy bowl.
Let the chocolate set completely. Then loosen the balloon from the edges of the “white chocolate bowl”, and cut a hole in the balloon to deflate it. Carefully remove the balloon. Use a hot knife to trim the edges of the white chocolate bowl (skull cap) to create a smooth edge. Set aside until needed.
Mix the jello with the hot water and whisk until the gelatin and sugar have dissolved. Add the strawberry pieces, cold water and evaporated milk. Whisk to combine and pour the mix into a flat dish. Refrigerate until set.
Once the jello has set, cut it into 1 - 2 inch cubes. Set aside until needed.
Evenly coat the cake halves with the bourbon syrup. Be generous and make sure to coat each half with the syrup on all sides. You will probably use about half of the sugar syrup recipe (maybe a little more). Let the cakes completely absorb the syrup.
Place the back part of the skull on a cake board. Spread a thin layer of chocolate ganache and stick the front (face) part of the skull onto the base. Use a skewer to hold the two halves together. Place the cake in the freezer for about an hour just to harden up the ganache and to make sure the cake is set together.
While the cake is being chilled, form a base (to support the skull so that the front of the skull is facing forward) with the cake scraps.
Once the cake has set, stick the “cake base” behind the skull using chocolate ganache. You can shape and/or trim the cake scraps to fit properly. Refrigerate or freeze until set. Do not freeze the cake, as the next step is to cut the cake to shape it.
Refrigerate for about 30 min - 1 hour, just until the cake scraps harden and set. Make the chocolate ganache during this time.
DAY TWO, WHITE CHOCOLATE GANACHE - place the chilled cake on a cake rack and then place the rack over a cake tray (to catch the white chocolate ganache that drips down). Pour or spread the white chocolate ganache over the cake. Use an offset spatula to spread the white chocolate so that it coats the cake all over. Once the cake is completely coated (it doesn’t have to be neat), keep it in the fridge for a couple of hours to let the white chocolate set. Once the chocolate layer has set, you can use a small spatula, gloved hands (or use plastic wrap), and other fondant tools to shape the white chocolate layer on the cake. Using a sharp point, carve in some teeth on the skull. The cake is now done and should be kept in the fridge until you are ready to serve.
Place the cut up jello pieces carefully inside the skull cavity. They will slip, so carefully place them on top of each other (you may not need all the jello).
Cover the jello layer with the popping candy white chocolate skull cap. Warm up the red velvet sauce over medium heat white stirring (to avoid clumping and scrambling). The custard should be steaming, but not boiling.
Serve the cake on a cake tray with the steaming red velvet custard sauce. Pour the sauce immediately over the skull cap, and listen for the crackling of the skull cap as it dissolves and activates the popping candy. The skull cap will melt away to expose the strawberry jello “brain” and the skull will have “bloody” red velvet custard dripping down.
Slice the cake and serve with the jello and custard. Enjoy!
