Use cornstarch as you would flour when making dough. Dust your work surface, hands, rolling pin, and cutters. Line a cookie sheet or tray with parchment paper or a non-stick baking mat.
Knead the white fondant in your hands to make it soft and pliable and roll to ¼"/0.5cm thick.
Using a 2"/5cm round cookie cutter, cut out 48 white circles to create Minnie's ears.
TIP! Always make extra fondant decorations as backup!
Place the white circles onto the prepared cookie sheet.
Leave the white circles to dry overnight.
To decorate the ears after they have dried, place the leaf stencil on top of each of the white circles and use the two different shades of green edible marker to color on the leaves. You can do this free hand if you have the artistic confidence to do so!
To make the cupcakes, preheat the oven to 180C/350F/Gas 4. Line cupcake pans with 24 cupcake liners and set aside.
Using an electric handheld or stand mixer, place the cake mix, butter, milk, and eggs into a large bowl and mix until combined and smooth.
Use an ice cream scoop to divide the cupcake batter between the liners - about three-quarters full.
Bake for 20 minutes or until an inserted toothpick comes out clean.
Leave to cool in the pan for about 5 minutes before transferring to a wire rack to cool completely before decorating.
To make the frosting, use an electric stand or handheld mixer and add the butter, powdered sugar, cream, and vanilla to the bowl.
Beat on medium speed until creamy and smooth and stiff peaks form.
Transfer 2 cups of frosting into a large piping bag fitted with a star tip. Set aside.
Pour all of the different colored sprinkles into a bowl and stir to mix.
Use a medium ice cream scoop to place a scoop of frosting on top of each cooled cupcake and use an angled spatula or knife to smooth and flatten slightly into a thick disc.
Dip and roll the frosted cupcakes into the sprinkles to cover.
Using the prepared frosting bag, pipe a swirl of frosting on top of the sprinkles layer.
Place the ears on either side of the frosting swirl.
Place a large flower in the center of the ears.
Place two leaves behind the large flower and some smaller flowers in front and behind to create a floral headpiece (instead of Minnie's usual bow!).
Enjoy and Have a Tropical Day!
