Preheat oven to 350°. Line baking sheets with parchment paper.
In a large bowl, beat butter and sugars with a mixer at medium speed until creamy. Add egg and egg yolk, one at a time, beating well after each addition. Beat in bourbon.
In another large bowl, stir together oats, flour, salt, baking soda, baking powder, cinnamon, and ground red pepper. Gradually add oat mixture to butter mixture, beating until smooth. Beat in pecans and white chocolate. Drop mixture by heaping tablespoonfuls 2 inches apart onto prepared pans.
Bake until golden brown, about 11 minutes. Let cool on pans for 2 minutes. Remove from pans, and let cool completely on wire rack.
