Bake your cakes and allow them to cool completely.
Place the 8 inch cake on a cake board (should be the same size as your cake) and ice it smoothly. You can cut in half lengthwise and add a filling, if you like. I didn't do it.
Place one 6 inch cake on a cake board (should be the same size as your cake). Spread icing on top evenly. Place the second 6 inch cake on top of the icing and press gently to secure into place. Frost the entire cake smoothly in chocolate buttercream.
Roll out fondant and spread it over these iced cakes.
Cut off excess fondant around the base of each cake with a pizza cutter.
Use a fondant smoother to smooth out the fondant on top and the sides of the cake.
Next, place the larger 8 inch cake on a serving dish or a cake stand.
Push 5 bubble tea straws or wooden dowels around the center of the cake for support.
Spread some icing on top of the straws.
Place the tall 6 inch cake on top of this icing. Press gently to secure into place. The icing should work like "glue."
Brush melted chocolate behind each jumbo sprinkle and stick them around the cake.
For the final step, stick a braided white fondant border around the base of both your tiers. Instead of this, you can just pipe a border with white buttercream icing. Enjoy!
