1 large egg
1/3 cup granulated sugar
1/3 cup packed light brown sugar
3/4 teaspoon baking soda
3/8 scant teaspoon kosher salt
1/2 teaspoon vanilla extract
1/2 cup peanut butter (4.8 ounces on a scale)
3 tablespoons unsalted butter, melted
2 1/2 tablespoons all-purpose flour
1 1/2 cups quick-cooking or old-fashioned (not instant) oats
1/4 cup semisweet chocolate or peanut butter chips
1/4 cup mini candy-coated chocolates (M&M’s)
1/3 cup chopped, lightly salted peanuts
- Preheat oven to 250 degrees. Line a large (about 18-by-13-inch), rimmed, heavy-duty baking sheet with parchment paper.
- In a mixing bowl, stir together the egg, both types of sugar, baking soda, salt and vanilla. Stir in the peanut butter and butter. When mixed, add flour and stir until blended. Lastly, stir in the oats, chips, candies and peanuts.
- Empty onto the baking sheet and divide dough into two sections.
- Dampen fingers and press each section down to make it as thin as possible. You could make one big slab, but making two gives you more edge pieces and more crunch.
- Bake for 45 minutes. Remove from the oven and slide parchment onto a cutting board. With a pizza cutter, cut the slabs into multiple uneven pieces—but do not separate cut pieces, as the cookies will still be rather crumbly at this point. Return parchment paper with cookies to baking sheet.
- Return to the oven and bake for another 15 to 20 minutes. Let cool for about 10 minutes on baking sheet and carefully transfer to a wire rack to cool completely. Cookies should crisp as they cool.

Cook’s Tip: If you have some thicker pieces that aren’t crunchy once cooled, throw them back in the 250-degree oven for another 10 to 15 minutes, then let cool. The thinner you press the slabs, the better chance you have of getting crunchy bark.
