Prepare your cupcake casings.

Preheat oven to 170°Celsius.

Beat butter and both sugars till light and fluffy. Add eggs, one at a time, beating well after each addition.

Sift the flour, cocoa powder, baking powder and salt. Fold in the sifted ingredients into the creamed mixture alternately with milk, starting and ending with flour.

Add in the vanilla extract and mix well.

Pour batter into baking cups or cupcake liners until they are about two thirds full.

Bake the chocolate cupcakes for 15 to 20 minutes or until a toothpick inserted in the center of the cupcakes comes out without any wet batter sticking to it.

Remove the cupcakes from oven and let them cool completely before decorating.

To make the buttercream, cream the shortening and powdered sugar until light and fluffy.

Add milk if the buttercream is too stiff.

Level the top of the cupcakes (if domed) with a serrated knife.

Apply a thin layer of green icing with a palette knife. Make sure the cupcakes are well covered with a smooth coat of green buttercream.

To pipe the flowers, hold the piping bag fitted with tip number 104.

Place the tip at the edge of the cupcake and gently squeeze your piping bag to let the icing out.

Release the pressure on the piping bag and pull the piping tip towards the center of the cupcake to make the first petal.

For the second petal, turn the cupcake to 90 degrees, and pipe another petal in a similar manner to the first petal.

Repeat the process on the left and right of the first two petals. That should make 4 petals.

Repeat the process for the next 4 petals, by piping one petal in between each of the earlier piped petals.

Finally, finish off the petals piping by filling up one petal each in between all the petals that are already on the cupcake. That completes the daisy petals.

For the flower center, pipe some yellow icing in a circular motion with round tip number 5.

Lift the piping tip and encircle the yellow buttercream center with tiny dots of yellow icing to complete the decoration.

Repeat for all the cupcakes to complete the buttercream daisy cupcakes.
