In a bowl, mix flour, cocoa, sugar, soda and salt, then pour in water, oil, vinegar and essence until completely combined.

Grease and flour a half sphere mold, pour batter, and bake on preheated 350 F for 25-30 mins.

Meanwhile, place marshmallow in a large bowl, add in water. Microwave for 2.5 mins total, at 30 secs intervals. Each time, take out, stir, and back to microwave, and repeat steps.

Dump lightly icing sugar on clean flat surface.

Once marshmallow melted, pour on top of icing sugar. Knead until you form a nice pliable dough (you won’t use the whole bag of icing sugar, there will be leftover).

Wrap and let rest at room temperature while cake baking and cooling.

Unmold cake as soon as baked, and let cool completely at room temperature.

Next, let’s work on the chocolate smash.

Melt white candy melts at 30 secs intervals in microwave, pour into the mold (am using tier cake mold). Make sure center is hollow. For easier, instead pour chocolate, you can brush the melted chocolate onto the mold instead. This is for top tier.

For middle tier, do the same, but with blue candy melts.

For bottom tier, use the white chocolate melt again. If by now the melted chocolate is kinda harden in the bowl, use microwave to remelt it.

You may add vegetable shortening, when needed, for making the melted chocolate smoother.

Let harden chocolate in the fridge.

You can use homemade or store bought buttercream, or Nutella, jam, honey, etc for the cake. You can slice the cake into layers or leave it as is.

As for this one, I brushed the cake with jam/jelly, no layers. Place cake on a cake board that is the same size as the cake.

Roll flat the marshmallow fondant, and cover the cake and the cake board with it. Set aside.

Brush round styrofoam all over, with vegetable shortening.

With leftover marshmallow fondant, reknead, the reroll flat, then cover the styrofoam.

Stack the half sphere cake on top of styrofoam, by pushing through a cake dowel.

Place small gifts next to BB8, unmold chocolate tier, and carefully hide the gifts under the chocolate tier. Decorate tier as well.
