Servings14 open-faced cookies or 16 sandwich cookies (with doubled cookie dough)
INGREDIENTS
Vanilla pastry cream:
- 360 g (1½ cups) whole milk
- 1 tsp vanilla bean paste (or 2 tsp vanilla extract)
- 4 US large/UK medium egg yolks

- 40 g (3 tbsp) caster/superfine sugar
- ½ tsp vanilla bean paste (or 1 tsp vanilla extract)
- 130 g (1 cup + 1 tbsp) plain gluten free flour blend (I used Doves Farm Freee plain gluten free flour that doesn’t have any xanthan gum added. You can also mix your own gluten free flour blend using this recipe. Note that for this homemade blend, 1 cup = 150g, so ideally use a kitchen scale for best results.)

- 20 g (4 tsp) whole milk, room temperature
Chocolate ganache:
- 60 g (2 oz) dark chocolate (55-70% cocoa solids), chopped
