"A Valentine's treat for your partner, friends or family"

With Valentine's Day coming up, we thought we'd give you a recipe that's perfect to make as a present for your partner, crush, friends or family! You could even just make these as a delicious treat for yourself because self-care is the best kind of care.


These cookies can be personalised with words to suit the recipient and are a great way to send a sweet message to someone. 


For the cookies

  • 250g Unsalted Butter

  • 140g Icing Sugar

  • 1 Egg Yolk

  • 1 tsp Vanilla Extract

  • 375g Plain Flour

For the icing

  • 1 Egg White

  • 225g Icing Sugar

  • Food Colouring


  • Mixing Bowl

  • Wooden Spoon

  • Rolling Pin 

  • Round Cookie Cutter

    • or the rim of a glass

  • Palette Knife 

  • Baking Tray

  • Cooling Rack

  • Electric Whisk

  • Piping Bag

  • Small Bowls

  • Optional: Heart Cookie Cutter

  1. Preheat your oven to 190 degrees Celsius

  2. Using a wooden spoon, mix together the butter (cubed), icing sugar, egg yolk and vanilla extract. Mix until it's all combined and creamy. 

  3. Keep mixing while you add the flour, a bit at a time until it combines to form a dough.

  4. Wrap the dough in clingfilm and chill in the fridge for 30 minutes.

  5. Put a light dusting of flour on your worktop and roll out the dough (about 1/2cm thick).

  6. Using your round cookie cutter (or glass rim), cut out as many circles as you can and transfer them to your baking tray, using a palette knife to release them from the worktop so they keep their shape.

  7. Re-roll the remaining dough and repeat until you run out of dough.

  8. Pop your cookies in the preheated oven for 10-12 minutes, until lightly golden.

  9. Carefully transfer your cookies to a cooling rack, using a palette knife or spatula.

  10. While you wait for them to cool,  put the egg white and icing sugar in a bowl and mix with an electric whisk until glossy, white and thick. It should be between the consistency of toothpaste and shampoo- if you find it's too thick, add 1/2 tsp of cold water at a time until you reach the perfect consistency

  11. Split your icing equally into the number of colours you'd like. We used the classic Love Heart colours; purple, green, orange, yellow, pink and white, plus a dark pink for the writing. 

  12. Add small drops of your food colouring (gel works the best as it doesn't change the consistency) and mix until fully combined. 

  13. Spoon your first base colour into your piping bag, with the smallest nozzle. 

  14. Start by piping a circle, close to the edge of your cookie. This acts as your barrier, so you can flood the middle with icing. 

  15. To flood the cookie with icing, squeeze out a big blob of icing into the centre and use the piping bag tip to gently push the icing towards the edge. Keep doing this until the cookie is filled with icing.

  16. Ice the rest of your cookies and leave to set. To check if they have set, gently press on the icing- if they have set, a dry film would have formed on the surface. Once they have set, you are ready to pipe your design. 

  17. You can either pipe the heart free hand, or if you have a heart shaped cookie cutter of the right size, press it lightly into the icing base and follow the outline.

  18. Pipe words into the middle of the heart, some examples are:

    • Love

    • BFF

    • Bae

    • Kiss

    • Hug

    • Yours

    • Mine

    • Fab

    • Hot Lips

  19. Leave the icing to set.

  20. ENJOY!
