140gSmartiesplus a few extra to press on top of the dough before baking.
Instructions
Heat your oven to 160°C fan, or 180°C conventional. Line two baking trays with baking paper.
Place the chilled butter in the Thermomix and blend for 12 sec/speed 5 until smooth and workable. Scrape down the sides of the bowl with a spatula.
Add the brown and white sugar, then mix for 20 sec/speed 4. Scrape the bowl thoroughly, then mix again for 15 sec/speed 4 until smooth.
Add the egg and vanilla, then mix for 15 sec/speed 3. Scrape down the bowl, then mix again for 15 sec/speed 3.
Add the flour, bicarbonate of soda and salt. Mix for 10 sec/speed 4, scrape the bowl well, then mix again for 3 sec/speed 4.
Fold the Smarties through by hand using a spatula so they stay whole. Tip: Transfer the dough to a regular mixing bowl for easier scooping and shaping, with the blades safely out of the way.
Shape the dough into walnut-sized balls and arrange them on the trays, leaving about 5 cm between each one. Press 2-3 extra Smarties on top. If the dough feels too soft to handle, place it in the fridge for 20 minutes to chill.
Bake one tray at a time for 12–14 minutes, until the edges are lightly golden and the centres remain soft. Keep the second tray in the fridge while the first one bakes.
Allow the cookies to cool on the trays for 5 minutes, then carefully lift them with a spatula onto a wire rack. They will firm up as they cool.
Notes
Tip: A few Smarties pressed on top may crack as they bake. If you want completely crack-free Smarties, skip adding them before baking and press them in as soon as the cookies come out of the oven while they are still soft.Storage: Store in an airtight container for up to 5 days. Freeze baked cookies for up to 2 months and thaw at room temperature. Unbaked dough balls can also be frozen and baked from frozen, adding 1–2 minutes to the bake time.
