Step 1

Preheat the oven to 180ºC (gas mark 4).

Step 2

Mix the flour, sea salt and bicarbonate of soda together and set aside.

Step 3

Separately, melt the butter and mix with the brown sugar and caster sugar until fully combined. Add the eggs, one at a time, beat, then add the vanilla extract.

Step 4

Combine with the dry ingredients and fold the chocolate chips into the mixture and beat to a cookie dough consistency. Divide the mixture into small balls (around 2 tbsp-size balls) and press your thumb into the middle to create a small well. Here, you can pour in the caramel sauce, or press in a fudge or caramel sweet of choice.

Step 5

Close the dough over the filling and roll gently into a ball in your palms. Place the balls onto a greaseproof lined baking tray and bake for 12-15 minutes. During this time the balls will spread and flatten into a cookie shape. Once baked, transfer onto a cooling rack, then enjoy!
