Bake cakes and allow them to cool completely.
While cakes are baking and cooling, prepare frosting too.
Trim domes of the cakes, if necessary so that they are flat.
Place the large 8x3 cake on a serving dish.
Use a spatula to ice the entire cake in frosting.
Roll out red fondant and spread it over the cake.
Trim edges around the base of the cake with a sharp knife or pizza cutter.
Stick 4 dowels on bubble tea straws in the center of the cake. Keep aside.
To make the top tier, place one 6x3 cake on a cake board (same size as the cake).
Use a spatula to ice the top in frosting,
Place the other 6x3 cake on top and press gently to secure both cakes tightly.
Ice the entire cake in frosting.
Roll out white fondant and spread it over the cake.
Trim edges around the base of the cake with a sharp knife or pizza cutter.
Place this cake on top of the other prepared 8x3 cake.
Roll out a blue and white strip of fondant and stick that around the center of the bottom tier with some water.
Roll out very thin blue fondant stems and branches and stick that on the top tier. Use very little water to stick, if necessary.
Make easy fondant flowers: Roll out red fondant. Use a small 1 inch petal flower cutter to cut out many little flowers. Place your flowers on a clean sponge. Use the veining tool to press the center of each flower until it leaves a tiny dent in the middle. Roll out blue fondant balls and stick them in the middle dents with little water.
Stick these flowers on the blue branches of the prepared cake with water.
Scatter some flowers along the second tier of the cake too. Enjoy
