• Add the bisquick baking mix to a large bowl.
• In another bowl, beat well the egg to combine the yolk & white very well.
• Add the sugar to the beaten egg, mix well to combine until the sugar dissolves.
• Also add the vanilla extract to the egg sugar mixture, mix well.
• Slowly add the sugar egg mixture to the bisquick baking mix in the other bowl. Mix using a spoon until all ingredients are well mixed.
• Add the m&m candies and mix in with the rest of the ingredients.
• Now, add the oil also to the bowl and knead using your hands to form the cookie dough. The dough will be quite sticky, but that's okay we are going to chill this prepared cookie dough.
• Once the cookie dough is made, place the cookie dough in the refrigerator and chill for at least one hour.

To make the cookies:

• Preheat the oven to 350 degree Fahrenheit.
• Divide the dough into two equal halves and make equal sized cookie dough balls from the first half (keep the other half of the cookie dough refrigerated until ready to bake).
• Place the cookie dough balls in a prepared baking sheet lined with parchment paper.
• Make sure to leave enough space between the cookie dough balls since the cookies will spread as they bake.

  I recommend placing only two cookie balls in the same row to avoid the cookies sticking to each other as they bake.
• Now, gently flatten the cookie balls a bit with your palms. Make sure not to flatten a lot, but a bit of flattening the cookie balls will help the cookies bake fast without getting the m&m's melted.
• Place the baking sheet in the preheated oven and bake for about 12 minutes until the cookies are done and the edges are beginning to turn slightly brown in color.
• The m&m cookies tend to melt a bit if they are left in the oven for more than the recommended cooking time (I do this sometimes!) but they are still very delicious!
• Once the cookies are baked, transfer the cookies from the hot oven immediately to avoid further baking.
• The cookies will look too soft as soon as they are baked, but they will harden just fine once they are cooled.

  Allow the cookies to completely cool down, enjoy with a cup of tea, coffee or milk as you like!
• Follow the same above steps for the remaining half of cookie dough as well, to bake the remaining cookies.
