1. Add the spelt flour, confectioners’ sugar, and vanilla custard powder to a large bowl and mix to combine. Add the butter and vanilla extract and mix in. Knead until you get a nice and smooth dough. Divide the dough into two equal portions and color one portion with a little pink food coloring. Wrap the dough (separately) in plastic wrap and place in the fridge for about 2 hours.

2. Preheat the oven to 350°F (180°C). Line a baking sheet with baking parchment and set aside. Take the dough out of the fridge and let it warm up a little.

3. Divide both dough pieces into 20 portions and shape each portion into a small ball. Cut the balls in half. Press a colored and uncolored dough piece together (at the cut edges) and roll between your hands – this should give you two-tone balls. Place them with enough space in between on the baking sheet (they spread quite a bit) and press them down with a fork. This will create a line pattern.

4. Bake the cookies for about 12-14 minutes. Remove the cookies from the oven and let cool down briefly on the baking sheet, then transfer to a wire rack and let cool down completely. Repeat with the remaining dough. Store the cookies in a tin box in a cool place.
