1-First, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to set up your baking space.

2-In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, creating a solid base.

3-Beat in the egg one at a time, then mix in the vanilla extract to blend everything well and add flavor depth.

4-In another bowl, whisk together the flour, baking powder, baking soda, and salt, then slowly add this to the wet mixture to avoid lumps and ensure even texture.

5-Fold in the 1 1/2 cups of candy-coated chocolates and chocolate chips gently so they spread out without breaking.

6-Scoop rounded tablespoons of dough onto the baking sheet, leaving about 2 inches between each for proper spreading.

7-Bake in the oven for 10-12 minutes until the edges turn golden but the centers stay soft for that gooey feel.

8-Finally, let the cookies cool on the sheet for 5 minutes before moving them to a wire rack. For vegan or gluten-free versions, use the substitutes from the ingredients section to keep the texture spot on.
