Creating your One Bowl Peppermint Brownies is straightforward when you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. Prepare Dry Ingredients: In a large bowl, whisk together the granulated sugar, brown sugar, cocoa powder, flour, salt, and baking powder until well combined.
3. Add Wet Ingredients: Pour in the vegetable oil, eggs, vanilla extract, and peppermint extract. Mix until the batter is smooth and fully combined.
4. Incorporate Chocolate Chips: Gently fold the semi-sweet chocolate chips into the batter, ensuring even distribution.
5. Transfer to Pan: Pour the brownie batter into the greased baking pan, spreading it evenly.
6. Add Topping: Sprinkle the crushed peppermint candies over the top of the batter for an extra festive touch.
7. Bake: Place the baking pan in the preheated oven and bake for 25-30 minutes. A toothpick inserted into the center should come out with a few moist crumbs.
8. Cool: Once baked, remove the brownies from the oven and let them cool in the pan for about 5-10 minutes.
9. Slice and Serve: After cooling, cut the brownies into squares and enjoy!
