The Original Recipe
2 1/4 Cups all-purpose flour
1 tsp baking soda
2 sticks unsalted butter at room temperature
1 cup packed light brown sugar
1/2 cup granulated sugar
1 tsp salt
1 Tbsp vanilla extract
1 large egg plus 1 egg yolk
1 cup Pretzel M&M's
3 oz bittersweet chocolate, chopped
1/2 cup toffee pieces
3/4 peanut butter chips
Preheat oven to 350.
Whisk the flour & baking soda in a bowl.
Cream the butter, brown sugar and granulated sugar on low speed until incorporated then increase to high speed and beat until light and fluffy.
Add the salt, vanilla, whole egg and egg yolk to the mixer; beat until thoroughly combine. Add the Pretzel M&M's and beat for a few seconds until slightly crushed. (I have a stand up Kitchen Aid but if you are just using a hand mixer I would suggest crushing these before.)
Gradually add the flour mixture, mixing on low speed until just combined. Mix in the bittersweet chocolate, toffee pieces and peanut butter chips.
Roll heaping tablespoonfuls of dough into balls and place on baking sheets about 2" apart. Slightly flatten with your fingers.
Bake until the edges are golden brown. 11-13 minutes.
For my version I substituted 1/2 cup chocolate chips for the bittersweet chocolate, 1/2 cup chopped peanuts for the toffee, and 1/2 cup of caramel bits for the peanut butter chips. That was just the right amount of everything for me but if you like more of one thing than the other just play around. The result was delicious!
