Chocolate chip cookies are great, but these Smarties Cookies have a little nostalgic charm to them that makes them extra special and perfect for anyone's birthday. You only have to chill the dough for 20 minutes before baking, which is also such a win!

Why This Recipe Works
These cookies are made from a cookie dough that is filled with both colorful Smarties and dark chocolate chips. The addition of the dark chocolate helps balance out the sweetness of these cookies.

Key Ingredients
To make these colourful smarties cookies, you will need the simple ingredients listed below. Remember always to use fresh room temperature ingredients when baking.

Unsalted butter - Use melted unsalted butter for this recipe.
Sugar - This recipe uses a combination of white granulated sugar and demerara sugar.
Cake flour - Choose cake flour, all-purpose flour, or plain flour for this recipe.
Dark chocolate - I used roughly chopped Lindt 75% dark chocolate for this recipe. I recommend doing the same or using dark chocolate chips instead.
Smarties - these colourful candies are the star of the show, so be sure to find some! Otherwise, M&M's will also work in this recipe.
See the recipe card for full information on ingredients and quantities.
Variations
I love using both milk and dark chocolate in cookie recipes to balance out the sweetness. You can do the same or use a combination of Smarties and milk chocolate chips for a sweeter cookie. You can also choose to use just Smarties if you prefer.
How to Make Smartie Cookies
STEP 1: Preheat the oven. Preheat the oven to 200°C (350°F) and line two large baking trays with parchment paper.

STEP 2: Combine butter and sugars. To a large mixing bowl, add the melted butter and both sugars. Stir together using a wooden spoon.

STEP 3: Add egg and vanilla. Add the egg and vanilla to the creamed mixture and mix again until well combined.

STEP 4: Sift dry ingredients. In a bowl, sift together the baking soda, salt, and flour. Add the flour mixture to the cookie dough batter and mix with a wooden spoon until a homogeneous dough forms.

STEP 5: Add chocolate chips. Add the roughly chopped dark chocolate and whole Smarties to the dough. Mix through. Chill the cookie batter in the fridge for 20 minutes.

STEP 6: Portion. Portion the dough into eight large cookies using an ice cream scoop. Place the cookies onto parchment-lined baking sheets, giving generous spacing between the cookie dough balls.

STEP 7: Bake. Bake one tray of cookies at a time in the center of the oven for about 8 minutes, or until the cookies are a light golden brown, their edges are crisp, and they have spread slightly. Remove the cookies from the oven, sprinkle them with a bit of sea salt, and press in some extra Smarties while the cookies are still warm. Allow the baked cookies to cool on a wire rack. Serve and enjoy!
Hint: Cookies hardly ever bake round on their own, so to get that perfect round shape, use a small bowl or chef's ring to help shape the cookies. Place the bowl or ring over the cookie as soon as it comes out of the oven and create a circular motion around the cookie to reshape it into a circle.

Storage
These cookies are best eaten soon after baking, once they have cooled slightly. This is when they are fresh and crisp with molten chocolate chips!
If you have any leftover cookies, store them in an airtight container at room temperature for about a week. If the cookies have softened, crisp them up in an air fryer or the oven for a few minutes.
You can choose to freeze the cookie dough before or after baking the cookies. To do this, first portion out the cookies, then wrap each portion in plastic wrap or place them in resealable freezer bags and freeze them for up to three months. For raw cookies, bring the dough to room temperature before baking.
Expert Tips
For the perfect soft chocolate chip cookies, follow my top tips below

- Use room temperature ingredients.
- Choose quality chocolate chips and chocolate bars for the best-tasting cookies.
Smartie Cookies FAQs
The eggs I use weigh 56 grams. If you're unsure if you have the same eggs, weigh the ones you have and adjust the amount accordingly.
I always recommend using a kitchen scale rather than cups when baking. This way, you can ensure you've measured correctly and that your baked goodies come out perfectly.
You want to bake these cookies in a hot oven for a short period. This way, they will crisp on the outside while remaining gooey on the inside. Bake four cookies at a time, and make sure you use an oven thermometer to test the actual oven temperature. If the oven is too hot, the cookies will burn on the bottom. Adjust the temperature and baking time for the second batch as needed.
