To make the 'Love' toppers, place the printable template onto a cookie sheet and lay a piece of wax paper on top.
Melt the chocolate in a microwave for 30 seconds or until smooth then transfer to a piping bag fitted with a round no. 2 piping tip.
Pipe the word out at least 22 times, with some extras in case of breakage.
Leave to harden for a few hours in a cool, dry place.
To make the cupcakes, preheat oven to 180C/350F/Gas 4, and line cupcake pans with 22 cupcake liners.
Sift the flour, cocoa powder, baking powder, baking soda, and salt into a large bowl.
Add the brown and white sugars to the flour mixture and stir to combine.
Add the oil, buttermilk, egg, and vanilla extract. Stir until smooth.
Scoop the batter into the cupcake liners and bake for 17-22 minutes or until an inserted toothpick comes out clean.
Remove the cupcakes from the oven and allow to cool for 5 minutes before transferring to a wire rack to cool completely.
To make the frosting, place the butter into a mixing bowl and with an electric mixer (stand or handheld) mix on medium speed for 1 minute.
Add the powdered sugar 1 cup at a time, beating to combine.
Add the cream and vanilla extract and mix on medium-high speed until smooth and combined.
Divide the frosting in half.
Mix in pink gel food coloring to one of the bowls of frosting to the desired shade of pink.
Scoop the pink frosting into one side of a large piping bag fitted with a star tip, and then scoop the white frosting onto the other side of the piping bag.
Pipe swirls on top of the cooled cupcakes.
