Step 1: Cake Cream
Ingredients Needed
- 200g Cake Cream (Swiss Meringue Buttercream)
- 125ml Warm Water
- 227g Softened Butter

Instructions
- Add your Cake Cream and warm water to a mixer with a whisk attachment and mix at high speed.
- Whisk till thickened then add your softened butter and continue to whisk on high speed.
- It will look curdled at first but keep mixing and your mix will become smooth and thick.
Step 2: Acetate
- Measure your cake height once crumb coated allowing an extra cm.
- Mark a sheet of acetate with an edible Marker.
- Cut your acetate and make sure you have enough acetate to wrap around your cake. If not, you can sellotape two strips together
- Print off a pattern from online and place it under your acetate. Pipe a small bit of Cake Cream under the acetate in the corners to stick it down to your paper design.
- Pipe your pattern onto your acetate using your different Cake Cream Colours making sure to leave no gaps between the colours.
- Fill in your background colour carefully making sure not to smudge your design. Lift up a corner gently to make sure there are no gaps in your design.
- Cut the bottom of your paper so it is flush with your acetate.
- Carefully lift your acetate up with the paper and wrap around your cake and remove the paper. Make sure that it sits flush with the bottom of your cake.
- Use a smoother to help smooth and adhere the Cake Cream to your cake.
- Using scissors, cut away the excess so it lines up nicely.
- Using a pallet knife scrape away any excess Cake cream from the top of your acetate.
- Fill in the top of your cake with Cake cream and smooth.
- Set your cake in fridge for at least 30 minutes or until your Cake Cream is set firm then remove the acetate carefully.
- Smooth the top further if required.
Step 3: Tropical Leaves
- Use a small bit of sticky sugarpaste to remove your Sweet Stamp pieces.
- Use your Sweet Stamp Pick up pad and press down on your sweet stamp to secure it.
- Press your sweet stamp onto your cake covered in sugar paste and have fun creating your design!
- Paint in your Design using Edible art Paints and Your Sweet stamp brushes. Mix with dipping solution to dilute your paints and create a water colour effect.
- Paint in your desired background colour.
- For an added dimension, roll our some sugarpaste and emboss with your sweet stamp
- Cut around your design and paint in to match.
- Add your cut outs to your design using edible glue to stick.
Step 4: Canvas Topper
- Roll our some sugarpaste about 3mm deep. Cut out your shape for your blank canvas topper using the Blank canvas cutter.
- Wet your Blank Canvas Topper and gently pick up and lay your sugar paste on.
- Select your letters from your Sweet Stamp set and position onto your topper as desired. If you are short a letter just leave the space for it. Use your Large Pick up to press your letters and emboss your sugar paste.
- Press in any letters where you where short individually.
- Dilute Edible art paints in red and green with dipping solution and start to dab your colour on starting with red in the middle then pink and out to green.
- Using Black Edible Art Paint, carefully paint in your letters and leave to dry.
- Once dry, push into your cake.
Aaand you're done! A perfect Watermelon Cake, worth of any tropical themed party.
