gooey oat bars

Bake Sale Winning-est Gooey Oat Bars


From Smitten Kitchen Every Day, these bars are heaven to me: good with morning coffee, great with afternoon espresso, friendly for adults and children alike.


For the crust:

  • 1 3/4 cups (230g) all-purpose flour
  • 1/2 teaspoon fine sea salt or table salt
  • 3/4 cup plus 2 tablespoons (200g) cold unsalted butter
  • 1/3 cup (65g) granulated sugar

For the topping/filling:

  • 1/2 cup (115g)  unsalted butter
  • 1/2 cup (100g) granulated sugar
  • 3/4 cup (145g) dark brown sugar
  • 1/4 teaspoon fine sea salt or table salt
  • 3 large eggs
  • 1 1/2 teaspoons vanilla
  • 1 1/3 cups (105g) rolled oats
  • 1/2 cup finely shredded unsweetened coconut
  • 1 1/2 cups chocolate chips (I like a dark chocolate chip, 63% cacao or so), chopped white or dark chocolate, candy bars, dried fruit, or a mix thereof (with the dried fruit, a mix with chocolate is best or the sweetness of the fruit will be overwhelming)
  • powdered sugar, to finish


  1. Prepare your pan: Heat the oven to 350ºF. Line the bottom of a 9-by-13-inch baking pan with parchment paper (if using a cake pan, hang the parchment over the sides so the bars are easier to remove). Lightly coat the sides with nonstick spray.
  2. Make the crust: Combine the flour, salt and sugar in the bowl of a food processor. Cut the butter into chunks, and add it to the bowl, then run the machine until the mixture forms large clumps—that’s right, just keep running it; it might take another 30 seconds for it to come together, but it will. Transfer the dough clumps to the prepared baking pan and press them evenly across the bottom and 1/4 inch up the sides. Bake for 15 to 20 minutes, until very pale golden.
  3. Meanwhile, prepare the filling: Melt your butter in a medium saucepan over medium heat. Continue to cook the butter, stirring frequently, until golden brown bits form at the bottom, about 5 minutes. Remove from the heat and stir in the sugars and salt. Let cool for 5 to 10 minutes, then whisk in the eggs, one at a time, and the vanilla, and stir in the oats, coconut, and chocolate, fruit, and/or candy. Pour over the parbaked crust, spreading evenly.
  4. Bake the bars: Bake for 15 to 20 minutes, until the top is firm and golden and the bars are set or, at most, barely jiggle if shimmied. The bars are much easier to cut cleanly from the fridge, but they are gooiest when warm. Dust with powdered sugar before serving or selling for the prettiest finish.
  5. Do ahead: Store in the fridge for many days.
