We have made cookies in the past but this was a new recipe so it counts here.
The recipe came from allrecipes.co.uk but we used smarties instead of chocolate chips.
I have reproduced the recipe here for convenience:
250g plain flour
1/2 teaspoon bicarbonate of soda
1/2 teaspoon salt
170g unsalted butter, melted
200g dark brown soft sugar
100g caster sugar
1 tablespoon vanilla extract
1 egg yolk
325g chocolate chips (or smarties etc.)
(tweaked slightly from the original)
Preheat the oven to 170 C / Gas mark 3. Grease baking trays or line with parchment.
Sift together the flour, bicarb and salt; set aside.
In a medium bowl, cream together the melted butter, brown sugar and caster sugar until well blended. Beat in the vanilla, egg and egg yolk until light and creamy. Mix in the sifted ingredients until just blended. Stir in the chocolate chips by hand using a wooden spoon.
Drop cookie dough onto the prepared baking trays, with each cookie around 1-2 tablespoons of dough (for smaller cookies, reduce baking time slightly). Do not flatten the dough. Cookies should be about 8cm apart.
Bake for 20 to 25 minutes in the preheated oven, or until the edges are lightly toasted. Cool on baking trays for a few minutes before transferring to wire racks to cool completely.
