Description

A chewy oatmeal cookie with a buttery crisp streusel topping. It’s a new twist on an old favorite with a hefty helping of warm fall spices.


Ingredients

Scale

Cinnamon Oatmeal Cookie Dough

  • 3/4 cup (170g) unsalted butter
  • 3/4 cup (165g) light brown sugar
  • 1/3 cup (67g) granulated sugar
  • 1 3/4 cups (210g) all-purpose flour*
  • 1 tsp baking powder
  • 1/4 tsp baking soda
  • 1 tsp ground cinnamon
  • 1/4 tsp ground cloves
  • 1/2 tsp salt
  • 1 large whole egg
  • 1 large egg yolk
  • 1 tsp vanilla
  • 2 cups (180g) Old Fashioned oatsĀ 

Streusel

  • 2 Tbs (29g) unsalted butter
  • 1/3 cup (40g) all-purpose flourĀ 
  • 2 Tbs light brown sugar
  • 2 Tbs granulated sugar
  • 1 tsp ground cinnamon
  • 1 Tbs Old Fashioned oats
  • dash of salt

Instructions

  • Preheat the oven to 350F and line a sheet pan with parchment paper.
  • Next, melt the butter for both the cookie dough and the streusel.Ā  I melt them in separate bowls so I don’t get confused.Ā  If taking butter directly from the refrigerator, put it a microwave-safe bowl and cover it with a microwave-safe plate or lid in case the butter splatters during melting.Ā  Start by putting 45 seconds on the microwave at full power and then check the butter, continuing to microwave in 20 second increments until it’s mostly melted but some light yellow hunks of butter remain.Ā  Ā Then use a fork to stir up the hunks so that the butter is creamy and smooth.Ā  Set the streusel butter aside to cool.
  • Add the 3/4 cup (170g) melted unsalted butter to a large mixing bowl or the bowl of a stand mixer.Ā  Then add in 3/4 cup (165g) light brown sugar and 1/3 cup (67g) of granulated sugar to the butter and beat for 2 minutes until smooth and the sugar has a chance to dissolve a bit.
  • In a separate medium-sized bowl, add 1 3/4 cups (210g) of all-purpose flour, 1 tsp baking powder, 1/4 tsp baking soda, 1 tsp cinnamon, 1/4 tsp cloves and 1/2 tsp salt and whisk to combine.
  • Next, add your whole egg, egg yolk and 1 tsp vanilla to the butter and sugar mixture in the mixing bowl and beat until the egg is fully incorporated, scraping down the sides of a bowl with a spatula to mix in everything evenly as needed.
  • Next add the dry ingredients to the wet and mix until the dry ingredients are fully incorporated and just the faintest bit of flour bits are still visible.Ā Ā 
  • Then add 2 cups (180g) of Old Fashioned oats and mix until everything is fully combined, then set aside to rest while you make your streusel. This short resting time helps the oats to absorb some of the moisture in the dough, making it easier to scoop.
  • To make the streusel, add 1/3 cup (40g) of all-purpose flour, 2 Tbs light brown sugar, 2 Tbs granulated sugar, 1 tsp ground cinnamon, 1 Tbs Old Fashioned oats and a dash of salt to a small bowl and stir to combine.Ā 
  • Add the dry ingredients to the 2 Tbs cooled melted butter and work them together using a fork until clumps start to form and the butter is fully incorporated.Ā  Don’t break up the clumps too much because larger bits of streusel are tasty when they bake up.
  • To assemble the cookies, using a 1.5 Tbs cookie scoop, make a dough ball, then smooth it by rolling gently between your hands. The dough will be a little sticky but still rollable.
  • Then toss the dough ball gently in the streusel to fully coat the dough ball, pressing a few larger bits of streusel into the top of the dough ball.Ā  And sprinkle on a little extra streusel before gently placing the dough ball on the parchment lined baking sheet.
  • Continue the process until you fill a sheet pan with 5-6 cookies.Ā  Make sure there’s room between each cookie to spread as they bake.
  • Put the cookies into the oven at 350F and bake for 11 to 13 minutes.Ā  The cookies will be golden in color, but still have just an ever so slightly wet look on top in the crevice areas. That’s when the cookies are done baking.Ā  Be careful not to overcook them as they will turn out dry if overbaked.
  • As soon as the cookies come out of the oven, using a large round cookie cutter, use a circular motion around each cookie to shore up the edges to make them uniformly round and help to thicken them just a bit.
  • Allow the cookies to cool on their sheet tray for 5 minutes until they’re firm enough to transfer to a cooling rack to finish cooling for at least 20 minutes before enjoying.Ā  They get chewier the longer they rest.

Notes

  • I use Gold Medal all-purpose flour for cookie baking.
