In a large bowl, cream the butter, oil and sugars until well combined.
Add the eggs, one at a time, beating until fluffy.
Next, in a separate bowl add the flour, baking powder, baking soda, and stir to mix well. Add to the wet ingredients, and continue mixing just until it is well combined.
Stir in peppermint crunch pieces, chocolate chips, peppermint and vanilla extract. Mix well.
Using a small cookie scoop or tablespoon, form balls with the dough and place onto a cookie sheet. Optionally, slightly flatten each ball of dough with the bottom of a glass or the palm of your hand. Bake at 350 degrees for 7-8 minutes, until lightly golden on top. Remove to a wire rack to cool. Enjoy!
