- 1/4 cup vegetable oil (or melted butter for richer flavor)

How to Make Candy Bar Brownie Mix Cookies
Get ready for an explosion of chocolatey goodness that’s astonishingly easy to achieve! These Candy Bar Brownie Mix Cookies boast an intensely rich brownie-like texture with delightfully chewy edges and a gooey, molten center, studded with pockets of your favorite candy bar pieces. The preparation is incredibly straightforward, making them a perfect project for beginners or busy bakers. You can have these delightful cookies ready to bake in under 15 minutes, with a total time of about 25-35 minutes from start to finish, depending on your oven.
Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats to prevent sticking and ensure easy cleanup. This step is crucial for evenly baked cookies.
- Combine Dry Ingredients (from the mix): In a large mixing bowl, empty the contents of the brownie mix box. Do not add the ingredients listed on the brownie mix box for preparing brownies (like the extra eggs or oil for a cake-like texture). We are using the dry brownie mix as our primary flavor and texture base for the cookies.
- Add Wet Ingredients: To the bowl with the brownie mix, add the vegetable oil (or melted butter), the two large eggs, and the vanilla extract.
- Mix the Dough: Using a wooden spoon or a sturdy spatula, mix the ingredients together until just combined. Be careful not to overmix. The dough will be very thick and fudgy, similar to brownie batter. It might seem a little sticky, which is exactly what we want for a chewy cookie.
- Fold in Candy Bar Pieces: Gently fold in the chopped candy bar pieces. Distribute them as evenly as possible throughout the dough. Some pieces might melt slightly into the dough, creating delightful pockets of flavor.
- Scoop the Cookies: Drop rounded tablespoons of the dough onto the prepared baking sheets. You can use a cookie scoop for uniform size, or two spoons. Leave about 2 inches between cookies as they will spread slightly during baking.
- Bake to Perfection: Bake for 10-14 minutes, or until the edges are set and slightly firm, and the centers still look a little soft and underbaked. The key to fudgy cookies is to not overbake them. They will continue to set up as they cool on the baking sheet.
- Cool and Enjoy: Let the cookies cool on the baking sheets for about 5-10 minutes before transferring them to a wire rack to cool completely. This allows them to firm up and prevents them from breaking.

Storing and Reheating Tips
Storing:
- Room Temperature: Once completely cooled, store Candy Bar Brownie Mix Cookies in an airtight container at room temperature for up to 3-4 days. Placing a slice of bread in the container can help keep them soft and chewy.
- Refrigeration: For longer storage, you can refrigerate the cookies in an airtight container for up to a week. They may become a bit firmer, but the flavor will remain intact.
- Freezing Dough: You can freeze cookie dough balls before baking. Roll the dough into balls, place them on a parchment-lined baking sheet, and freeze until solid. Then, transfer the frozen dough balls to a freezer-safe bag or container for up to 2-3 months. Bake from frozen, adding a few extra minutes to the baking time.
- Freezing Baked Cookies: Baked and cooled cookies can also be frozen. Wrap them individually or in small batches in plastic wrap, then place them in a freezer-safe bag or container for up to 2-3 months.
Reheating:
- Room Temperature: If cookies have become slightly firm from refrigeration, simply let them sit at room temperature for about 15-30 minutes to soften.
- Oven/Toaster Oven: For a warm, gooey treat, reheat individual cookies in a preheated oven or toaster oven at 300°F (150°C) for 2-4 minutes, just until warmed through and slightly softened.
- Microwave: Reheating in the microwave is the quickest option, but be cautious not to overdo it, as it can make them tough. Microwave one cookie at a time for 10-15 second intervals until just warmed.
