Ingredients

  • 115 g Unsalted butter (Soft, cut into small dice, at room temperature)
  • 100 g White sugar
  • 100 g Brown sugar
  • 1 gousse Vanilla bean (Scraped)
  • 1 unité Egg (At room temperature)
  • ½ tsp Salt
  • 200 g All-purpose flour
  • 1 tsp Baking powder
  • ½ tsp Baking soda
  • 100 g Oat flakes (Preferably large flakes)
  • 50 g Sunflower seeds
  • 50 g Pumpkin seeds
  • 30 g Flax seeds (Whole or ground)
  • 100 g Milk chocolate chips

Instructions

  1. Cream the butter and sugars

    In the mixer bowl, add the softened butter dice, white sugar, brown sugar and the seeds from the vanilla bean. Mix on medium speed until a creamy and slightly foamy texture that lightens appears.

    Time: PT5M

  2. Incorporate the egg and salt

    Add the room‑temperature egg and the salt. Mix on a slightly higher speed for one minute until the mixture is homogeneous and smooth.

    Time: PT1M

  3. Add the dry ingredients

    Fold in the flour, baking powder and baking soda. Mix on low speed until a homogeneous dough forms without over‑working.

    Time: PT2M

  4. Integrate the flakes and seeds

    Add the oat flakes, sunflower seeds, pumpkin seeds and flax seeds. Mix gently to distribute them evenly in the dough.

    Time: PT2M

  5. Incorporate the chocolate chips

    Add the milk chocolate chips and mix one last time on very low speed to prevent them from melting.

    Time: PT1M

  6. Form the dough log

    Place the dough on a sheet of cling film, spread it slightly, then shape a log about 19 cm long and 5.5 cm in diameter. Seal the ends of the film and roll the log on the work surface to obtain a regular shape.

    Time: PT5M

  7. First chill

    Wrap the log in the film and place in the refrigerator for 3 hours to firm up the dough.

    Time: PT3H

  8. Slice and shape the cookies

    Remove the film, cut the log into slices about 1 cm thick with a sharp knife. Arrange the rounds on a baking sheet, spaced apart, then flatten slightly with the palm of your hand.

    Time: PT30M

  9. Second chill (before baking)

    Place the sheet with the cookies in the refrigerator for another 30 minutes so the shapes hold during baking.

    Time: PT30M

  10. Preheat the oven

    Preheat the oven to 180 °C on convection mode.

    Time: PT10M

    Temperature: 180°C

  11. Bake

    Bake the cookies for 15 to 17 minutes, until the edges are golden but the centre remains slightly soft.

    Time: PT16M

    Temperature: 180°C

  12. Complete cooling

    Remove the cookies from the oven and let them cool completely on the sheet or on a rack before handling.

    Time: PT20M

Troubleshooting

Cookies are too flat after baking.

Chill the dough longer (at least an additional hour) and flatten the rounds slightly before baking.

Cookies remain too soft in the centre.

Extend the baking time by 2 to 3 minutes or increase the temperature to 185 °C.

The dough is too dry and doesn't hold together.

Add a tablespoon of milk or yogurt to slightly moisten the dough.
