Preheat the oven to 375°F. Line 2 baking sheets with parchment paper.
In the bowl of a stand mixer fitted with the paddle attachment, add the butter, light brown sugar, and peppermint extract. Mix on low until combined and there’s no butter chunks.
Next, add the pumpkin and dry ingredients: flour, cocoa powder, baking powder, and sea salt in that order. Mix on low until combined into a smooth dough.
Chop 1 bag of Lake Champlain Organic Dark Chocolate Peppermint Snack Bites into small pieces.
Add the chocolate peppermint pieces and mini chocolate chips to the cookie dough and mix to combine completely.
Using your hands, or a cookie scoop, form the dough into 12 balls and place on the prepared baking sheets. Space them evenly apart, there will be 6 cookies per sheet.
Bake for 15 to 17 minutes or until the tops and edges are dry.
Sprinkle with flaky sea salt immediately after coming out of the oven (optional). Allow the cookies to cool completely on the baking sheets.
Store in an airtight container for up to 7 days.
