Using a 2"/5cm rectangle cookie cutter, cut out 22 rectangle brownies and place them onto a cookie sheet.

If using Wilton tubes of frosting, attach a round no.4 piping tip to the tube of black frosting, or alternatively, squeeze the frosting into a piping bag fitted with the same size tip.

Pipe a small blob of frosting on the back of the edible eyes. Place the eye onto the brownie in the top right as shown. Pipe an outline around the candy eyeball.

Pipe a squiggly line on the side opposite of the eye to create the
‘Spine’ of the book.

Pipe a straight line next to the squiggly spine line, and then pipe a squiggly line over the straight line. Pipe half circles on the corners of the spellbook brownie, then pipe to small circles on either side of the candy eyeball.

Repeat steps to decorate the other brownie rectangles then set them aside while you make your cupcakes

To make the cupcakes, preheat the oven to 180°C/350°F/Gas 4. Line cupcake pans with 22 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 evenly divide into the cupcake liners about 3/4 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.

Scoop 1½ cups of frosting into another bowl and stir in a few drops of purple food coloring. Remember you can always add more coloring, but not take it away! Stir in the food coloring until well combined and you reach the desired shade.

Color the remaining frosting neon green.

Place 1½ cups of green frosting into one-half side of a medium piping bag fitted with a star tip (WIlton 4B) and the purple frosting into the other half. Squeeze out some of the frosting to combine the colors and set aside.

Place the remaining green frosting into a large piping bag fitted with an open star tip (Wilton 1M).

Using the bag of green frosting pipe a ring of frosting on top of each cooled cupcake and add some green sprinkles.

Using the two-tone frosting, pipe a swirl of frosting on top of the green layer.

Carefully place the ‘spell book’ brownie on the frosting of the swirled frosting. Enjoy and Run Amok!
