If you have a friend who loves flowers, then you might consider making a birthday cake shaped like a flower vase and filling it with faux flowers for her birthday. While you will need a three-dimensional cake pan to pull off this project, the rest of the materials are basic and may already be in your kitchen. Be creative as you decorate the cake; consider using a colour diverse colour palette of icings and faux flowers. Keep in mind your friend's favourite colours and flowers.
Wash the cube cake pan thoroughly with soap and water and allow it to dry.
Prepare your cake mix as directed by its packaging in a mixing bowl and stir until smooth.
Pour your batter into the non-stick cube-shaped pan and bake it according to the package's instructions.
Remove your cake from the oven and allow it to cool. Once the cake is cool, carefully turn it over onto a cake stand and ice it according to your selected colour palette.
Wash the plastic stems of the flowers thoroughly with soap and water.
Insert the clean flower stems into the top of the cake in your preferred arrangement; you may need to snip long stems with wire cutters. The final product gives the illusion of a cube flower vase filled with flowers.
