Chocolate Bar Cookies

Golden on the edges and chewy in the middle, these soft baked Chocolate Bar Cookies are made using a selection box of Cadbury’s Heroes!

Chunks of Double Decker, Fudge, Creme Egg, Dairy Milk, Eclairs, Twirl, Wispa, Crunchie and Dairy Milk Caramel are dotted throughout the cookies. There’s a surprise in every bite! If you’re not a fan of Cadbury’s Heroes, you could instead use a selection box of Celebrations, Quality Street or just chop up your favourite chocolate bar 😊

How to make Chocolate Bar Cookies

Baking cookies couldn’t be easier! Just a few simple steps and you will have the most delicious, irresistible cookies.

  1. Make the cookie dough. My recipe uses melted butter, two types of sugar and an extra egg yolk for added richness and chewiness. This one-bowl method for the cookie dough will take no more than 5-10 mins, tops!
  2. Add the chopped chocolate bars. You’ll then chop up the chocolate bars and fold them into the dough.
  3. Chill the dough. This step cannot be skipped! Cover the bowl with clingfilm and put in the fridge to chill for at least 4 hours or overnight. This will develop the flavours and improve the texture.
  4. Roll the dough into balls. Use 2 tablespoons per cookie ball, roll into a ball using the palms of your hands and place on a baking tray.
  5. (under)Bake. 10-12 mins at 180°C is all these cookies need. You want the middle to be soft and underbaked and the outside edge slightly golden.

Chocolate Bar Cookies recipe (makes 10-12)


  • 160g unsalted butter
  • 100g white caster sugar
  • 150g soft light brown sugar
  • 1 teaspoon vanilla extract
  • 1 medium egg + 1 medium egg yolk, at room temperature
  • 250g self-raising flour
  • 200g Cadbury’s Heroes


  1. Melt the butter in 20-second blasts in the microwave until it turns to liquid.
  2. Add the light brown and caster sugar and mix together with a wooden spoon.
  3. Now add the vanilla extract, whole egg and egg yolk, and mix together until fully combined.
  4. Add the flour and fold together until the mixture forms a cookie dough.
  5. Chop the Cadbury’s Heroes into small chunks. Add to the cookie dough and fold together.
  6. Cover the bowl with clingfilm and place in the fridge to chill for a minimum of 4 hours, or overnight for best results.
  7. Preheat your oven to 180°C / 350°F and line two baking trays with greaseproof paper.
  8. Take the cookie dough out of the fridge and leave at room temperature for 10 minutes.
  9. Take two heaped tablespoons of cookie dough and use your hands to roll it into a ball. Place on the baking tray and do not flatten. Repeat this step until all the cookie dough has been used up.
  10. Leave about 8-10cm between each cookie ball so they have enough room to spread out. You may have to bake the cookies in batches.
  11. Bake for 10-12 minutes, until the cookies are lightly browned on the edges and the middle is still soft. Cool for 10 minutes on the baking tray, then transfer to a cooling rack.

Your Chocolate Bar Cookies will keep at room temperature, in an airtight container, for up to 3 days.

  1. These cookies are hands down some of the best I’ve ever tasted! A perfect balance of chewiness, and a gooey, chocolatey centre, with an added treat of guessing which of the “heroes” has found its way into your cookie!
