This recipe includes both UK metric and US cup measurements.
Note: Pay attention to chilling and setting times between stages to ensure good results.
Ingredients
Makes about 30–35 cookies.
For the cookies
- 250g (1 + 1/8 Cups) unsalted butter, room temperature
- 200g (1 Cup) golden caster sugar
- 1 tbsp vanilla extract
- 1 egg, beaten
- 450g (3 + 1/2 Cups) plain flour
For the royal icing
- 2 large egg whites
- 500g (4 Cups) icing sugar
- Squeeze of lemon juice
- Red food colouring gel
Essential equipment
- Electric stand mixer or hand mixer
- Spatula or wooden spoon
- Rolling pin
- 3 bowls
- 7cm cookie cutter
- Baking tray
- Piping bag (or piping bottle)
- No.3 writing nozzle
- Fork
You can use a piping bag fitted with a round nozzle, but a piping bottle can make flooding easier.
Cookie instructions – Part 1
In a stand mixer or large bowl with a hand mixer, cream the butter (250g), sugar (200g) and vanilla (1 tbsp) until light and fluffy. Add the beaten egg and mix until combined.

Tip in the flour (450g) and fold with a wooden spoon until it just comes together into a dough. Turn out onto a work surface, knead gently to form a ball, then divide into two portions.

Roll each portion between two large sheets of baking paper to about 6mm (1/4″) thick. Place both sheets in the fridge to chill for about 1 hour — chilling helps the cookies keep their shape when cut.

Royal icing instructions
In a clean bowl or mixer, beat the egg whites (2), icing sugar (500g) and a squeeze of lemon juice on high for about 5 minutes until stiff peaks form. Add cold water, a drop or two at a time, mixing between additions until the mixture loosens to soft peaks.

Spoon 3–4 heaped tablespoons of this thicker icing into a small bowl, cover tightly and reserve — this stiffer icing will be used to pipe borders.
Continue to add water, a little at a time, to the remaining icing until you reach a flooding consistency. Take 5–6 tablespoons of that flooding icing, colour it red, cover and set aside for the blood spatter. Cover the rest of the white flooding icing and set it aside too.

Cookie instructions – Part 2
Once the dough has chilled, remove from the fridge and cut as many 7cm circles as possible. Re-roll scraps to cut more cookies until the dough is used up. Chill the cut cookies for 15 minutes while you preheat the oven to 190°C (fan 180°C / 374°F).

Line a baking tray and space the chilled cookies, allowing room for slight spreading. Bake for about 10 minutes until the edges turn golden, turning the tray halfway for even colouring. Cool on the tray a minute, then transfer to a wire rack to cool completely. Repeat with remaining dough.

Decorating instructions
When cookies are completely cool, fill a piping bag with the stiffer border icing and pipe a neat edge around each cookie. Let the borders set for 15–20 minutes.

Once borders are firm, mix the white flooding icing and pour it into a piping bottle to flood the centres. Allow the flooded surface to set for 1–2 hours so it becomes firm to the touch.
For the splatter: protect your workspace and lay newspapers underneath. Stir the red flooding icing well, dip a fork into it, and flick or splatter the icing over the cookies to create random blood-spatter patterns. Work a few cookies at a time if you prefer. Let the splatter set for another 1–2 hours.

These cookies are dramatic, crunchy and lightly vanilla-scented — a perfect showstopper for Halloween. You can freeze uncooked dough in an airtight bag or tub for later use.
