Ingredients
- 12 tablespoons unsalted butter
- 1 1/2 cups (10.5 ounces) brown sugar
- 1 1/2 teaspoons vanilla
- 2 large eggs
- 1 1/2 cups (7.5 ounces) all-purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 30 Oreo cookies, coarsely chopped (or 2 cups other mix-in)
- 1 cup M&M's (or small pieces of other candy)
Instructions
- Preheat oven to 350 degrees F.
- Line a 9x13 baking dish or pan with foil and spray with nonstick cooking spray.
- In a large microwave-safe bowl, heat the butter in the microwave until melted.
- Remove from microwave and whisk in the sugar and vanilla.
- Then add the eggs and mix until smooth.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- Then add the dry ingredients to the wet and stir until just combined; don't overmix.
- With a rubber spatula, fold in the crushed Oreo cookies (or about 2 cups of other crushed cookies or candy).
- Scrape the batter into the prepared pan, smoothing the top with the spatula.
- Sprinkle the M&M's (or other small pieces of candy) over the top evenly and lightly press them down into the surface of the batter.
- Bake for about 30-40 minutes, or until the top is firm, cracked, and golden.
- Baking times may vary depending on the mix-ins and the type of pan.
- A toothpick inserted into the center should come out clean or have moist crumbs attached, but not gooey batter. Transfer pan to a cooling rack and allow bars to cool in the pan for at least 30 minutes.
- Then remove the bars from the pan (by lifting the foil out), cut them into bars, and serve.
