Trash Cookies


  • Crunch:

  • 55 grams corn flakes

  • 30 grams ready salted crisps

  • 15 grams malt powder

  • 15 grams caster sugar

  • 30 grams unsalted butter, melted

  • Cookie dough:

  • 225 grams unsalted butter

  • 250 grams soft light brown sugar

  • 100 grams caster sugar

  • 2 medium eggs

  • 1/2 teaspoon vanilla extract

  • 400 grams plain flour

  • 1 teaspoon salt

  • 1/2 teaspoon baking powder

  • 1 teaspoon bicarbonate of soda

  • 200 grams white and milk chocolate chips

  • 80 grams marshmallows, frozen


  1. In a large bowl, combine corn flakes, crisps, malt powder, sugar and melted butter and stir to crush together into smaller pieces. Spread out the mixture onto a baking tray lined with baking paper and place in a preheated oven at 170°C for 12-15 minutes to make a crunch.

  2. In a separate bowl beat together the two sugars with the butter for a good 5 minutes until paler in colour and creamy. Beat in the egg and vanilla extract.

  3. Sift over the flour, salt, baking powder and bicarbonate of soda and beat until evenly combined.

  4. Fold in the chocolate chips and cooled crunch and mix until combined. Evenly divide the dough and add 3 frozen marshmallows to the centre of each cookie. Close over the cookie dough and roll into a ball. Flatten the tops slightly. Place in the fridge until firm and chilled.

  5. Bake at 170°C for 10-15 minutes depending on the size. Don't over bake!

- These trash cookies may have a few ingredients you're not used to finding in a cookie, but don't knock it till you try it. They taste delicious. So into a bowl I'm going to add in some cornflakes. Yes, cornflakes. They add such a lovely flavor to the cookie. So what we're making here is the flavor for the cookie. We're baking this on a baking tray. It will turn into a crunch and we'll be adding this into the cookie. And it gives it such a depth. It's delicious. So up next I'm adding in some ready salted crisps. Weird, I know, but just go with it. It tastes great. And I'm adding in some malt powder and some sugar. And I'm going to bash that all together with a wooden spoon. You're just looking to break down some of those crisps and cornflakes to get some smaller bits. Finally, I'm going to pour over some melted butter and get that all evenly incorporated. That's nice and mixed. I'm gonna pour it onto a baking tray lined with some baking paper. Just give that a little spread around. And then that is ready to go into the oven for about 12 to 15 minutes until it's lovely and golden. My crunch is out of the oven. I'm going to leave that to cool completely while I get on with the rest of the cookie mixture. So into a big bowl I'm going to add in some soft light brown sugar. And I'm going to beat that together with some caster sugar and some unsalted butter. Now, I like to give that a good mix for at least five minutes to get that lovely and creamy and well mixed together. Into that I'm adding in two eggs and some vanilla extract to give it a bit of flavor. Don't forget to scrape down your bowl when making your cookies, as lots of it likes to stay up at the edges. I'm now going to sift over my dry ingredients, starting with some flour. Few more dry ingredients to add. I have some baking powder and some baking soda and a bit of salt that I'm going to sift too. Now, you can't have a cookie without some chocolate chips in there, and I'm going to be using some milk and white chocolate chips. They're going to be delicious. I'm just gonna fold those in with my spatula. And finally I'm going to fold in my cooled crunch mixture. This is going to add so much flavor and texture to these cookies. These cookies are lovely and chewy, and like crisps, they're extremely moreish. If you thought I was done with my unusual ingredients, I'm not. I'm gonna scoop some of the cookie dough up and I'm going to add three frozen marshmallows into the center. Now, that is the cherry on top for these cookies. Before placing those into the oven, I'm going to pop them in the fridge until they're nice and firm. So that is how you make my delicious and chewy trash cookies. Easy.
