Brown Butter Pumpkin Oatmeal Cookies

Ingredients:

  • 1 cup (2 sticks; 230g) unsalted butter
  • 2 cups (170g) old-fashioned whole rolled oats
  • 1 and 2/3 (208g) cup all-purpose flour (spoon & leveled)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 and 1/2 teaspoons ground cinnamon
  • 1 and 1/2 teaspoons pumpkin pie spice1
  • 1 cup (200g) granulated sugar
  • 3/4 cup (150g) packed light or dark brown sugar
  • 1 egg yolk, at room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (228g) pumpkin puree (see note - not pumpkin pie filling and not the whole can)2

Brown Butter Glaze

  • 1/4 cup (60g) unsalted butter
  • 1 and 1/2 cups (180g) confectioners' sugar
  • 3 Tablespoons (45ml) milk
  • 1/4 teaspoon pure vanilla extract

Directions:

  1. Important before you begin! If topping the cookies with the brown butter icing, you can brown the butter for both the cookies AND the icing together. Once it is all browned, set 2 liquid ounces (1/4 volume cup) aside for the glaze. You can use it in step 8. The rest (about 8 liquid ounces) is for the cookies, used in step 5.
  2. Brown the butter: Slice the butter up into pieces and place in a light-colored skillet. (Light colored helps you determine when the butter begins browning.) Melt the butter over medium heat, stirring occasionally. Once melted, the butter will begin to foam. Keep stirring occasionally. After 5-8 minutes, the butter will begin browning-- you'll notice lightly browned specks begin to form at the bottom of the pan and it will have a nutty aroma. See photo above for a visual. Once browned, remove from heat immediately and allow to cool for 5 minutes.
  3. Meanwhile, whisk the oats, flour, baking soda, salt, cinnamon, and pumpkin pie spice together in a medium bowl.
  4. Preheat oven to 350°F (177°C). Line two large baking sheets with parchment paper or silicone baking mats. (Always recommended for cookies.) Set aside.
  5. Pour the slightly cooled brown butter into a large bowl. Whisk in the granulated sugar and brown sugar until combined. Whisk in the egg yolk and vanilla extract until combined, then whisk in the blotted pumpkin (see note about blotting). Slowly mix the dry ingredients into the wet ingredients until combined. The cookie dough will be thick and sticky.
  6. Using a medium cookie scoop, scoop cookie dough into balls (about 2 heaping Tbsp of dough each) and place 3 inches apart on the cookie sheet. Slightly flatten the balls out-- see picture above-- as the cookies won't spread much unless you help out first!
  7. Bake for 14-15 minutes or until lightly browned and set on the edges. Remove from the oven and allow to cool for 10 minutes on the cookie sheet before icing.
  8. Make the icing: Whisk together the 1/4 cup of brown butter you reserved for the icing, along with the remaining icing ingredients until smooth. Dip the top of each cookie into the icing.

Make ahead tip: Iced cookies stay fresh covered in the refrigerator for up to 1 week. You can make the cookie dough and chill it in the refrigerator for up to 3 days. Allow to come to room temperature then continue with step 6. Baked cookies freeze well for up to 3 months. Unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Click here for my tips and tricks on freezing cookie dough.

Recipe Notes:

Adapted from my favorite pumpkin oatmeal cookies. Aside from the brown butter and the icing, today's cookies are chewier with a little more pumpkin flavor.

Instead of icing (or in addition to!), you can add 1 heaping cup of chocolate chips to the cookie dough. Or 1 cup of chopped nuts, dried cranberries, raisins, white chocolate chips, butterscotch morsels, etc.

  1. Instead of pumpkin pie spice, you can use 1/2 teaspoon ground ginger + 1/2 teaspoon ground nutmeg + 1/4 teaspoon ground allspice + 1/4 teaspoon ground cloves.
  2. Squeeze as much of the moisture out of the pumpkin puree as you can before adding it to the cookie dough. I simply squeeze the puree with paper towels. See photo in the post for a visual. This will help produce a less cakey cookie. Less moisture is a good thing in these cookies!
