Carrot cake meets cookies, a.k.a. the dessert combo of your dreams!
Position 2 racks in the upper and lower thirds of the oven and preheat to 375 degrees . Line 2 cookie sheets with parchment paper. Using an electric mixer, beat the butter and brown sugar until creamy, about 3 minutes. Mix in the eggs, vanilla and baking soda on medium speed until fluffy, scraping down the bowl as necessary. Mix in the flour on low speed. Stir in the carrots, granola and corn flakes.
Drop heaping tablespoons of dough about 2 inches apart on the prepared cookie sheets. Sprinkle with the granulated sugar and bake until golden, 15 to 20 minutes. Transfer to a rack to cool.
