Preheat your oven to 180C/160C Fan and Lightly Grease a 9″ Pie Dish – leave to the side for later.
With your stand mixer, beat the Butter and two Sugars together until light and fluffy and fully combined.
Add in the Eggs, Flour, Vanilla, Cornflour, Bicarbonate of Soda, and Salt and beat again till a cookie dough is formed. You will want to scrape down the sides to make sure its all incorporated well!
Add in 85% of your M&Ms and fold them through. Spread the cookie dough into the pie dish, and add the last of the sweets on top for decoration. You don’t have to do this, but I think it looks far nicer!
Bake in the oven for 30-35 minutes. If it looks really wobbly in the middle still, leave it in for another 5 minutes. (Some ovens can take longer!)
Remove the pie from the oven and let it cool a little. Either eat warm, or let it cool and melt some chocolate over, and sprinkle on some extra sweets (optional)
I used oodles of Chocolate M&Ms in this recipe, along with some Dark Chocolate Chips, Milk Chocolate Chips, and Milkybar Buttons, but you can use pretty much any chocolate sweet that you like. Different flavoured M&M’s would work, smarties, reeses pieces, etc!
This amazing Giant Cookie Pie will last about 2-3 days, but is best on the day of making. If you want it the day after, I suggest microwaving it for 20 seconds, then adding a scoop of ice-cream as its DELICIOUS.
I’ve never personally tried this mix as an actual cookie, but I don’t really think it’ll work too well. The mixture is too wet in my opinion… if you want a good cookie recipe, check out my Terry’s Chocolate Orange Cookies!
