1. Preheat oven to 180c/350f, and line three baking trays with parchment paper.
  2. Sieve flour into a large mixing bowl, and then add the sugar, cacao powder, salt and baking powder. Combine.
  3. In a separate mixing bowl, whisk together the vanilla extract, peanut butter, coconut oil and butter/vegan spread.
  4. Add the wet ingredients into the dry, and combine until a ball of dough is formed. I recommend using your hands for this step.
  5. If you have time, place the dough in the fridge for 30 minutes.
  6. Sprinkle some flour onto your work surface, and using a rolling pin, very gently roll the dough mixture out until flat. It needs to be about 5mm thick.
  7. Using a gingerbread man cookie cutter, create approximately 16-18 cookies.
  8. Gently place the cookies onto the lined baking trays, and bake in the oven for 15-18 minutes.
  9. Whilst the cookies are cooling, add your icing to a piping bag and cut a small hole in the bottom.
  10. Start with adding the eyes to the cookies, and letting them dry. Add eyeballs with black edible pen or chia seeds.
  11. Then decorate with multiple lines to make them look like Halloween mummies.
