These Brown Butter Espresso Oatmeal Chocolate Chunk Cookies are a cozy, bakery-style twist on a classic oatmeal cookie. Nutty brown butter creates a deep, toasty flavor, espresso enhances the chocolate, and old-fashioned oats keep each cookie soft and chewy in the center with lightly crisp edges.
Add butter to a saucepan, heat over medium-high heat stirring constantly for 5-7 minutes until the butter starts to brown. Scrape any brown bits off the bottom. Remove butter from the heat before it burns, you want it to have a dark amber color and nutty smell. Allow to cool slightly and transfer to a large mixing bowl.
1 cup Unsalted butter
To the butter, add in the espresso powder and stir to begin dissolving, Then add in the brown sugar, granulated sugar, eggs, and vanilla. Whisk to combine.
1 cup Granulated Sugar, 1 cup Light brown sugar, 2 whole Eggs, 1 tbsp Vanilla, 1 tbsp Instant Espresso Powder
To the wet ingredients, mix in the dry ingredients until fully combined. Fold in the oats and chocolate chunks. Cover dough and allow to chill for 25 minutes.
2 1/2 cup All purpose flour , 1 tsp Baking powder, 1 tsp Baking Soda, 1 tsp Salt, 2 tsp Ground Cinnamon , 1 1/2 cups Old fashioned oats, 6 ounces Semi-sweet or dark chocolate chunks
After chilling, line a sheet pan with parchment paper and preheat oven to 350 degrees F. Use a portion scoop or spoon to scoop even amounts of dough, about 2 ounces per cookie. Form into a ball and place onto the prepared baking sheets spacing about 2-3" apart. Repeat with remaining cookie dough.
If desired, press extra chocolate chunks into the tops of the cookies before baking, this created those bakery style chocolate puddles!
Bake at 350 for 9-11 minutes until golden brown, cookies will still be soft in the middle. Allow to cool for a few minutes on the cookie sheet before transferring to a cooling rack. Sprinkle with sea salt if desired and enjoy!
Notes
Brown the butter fully: Let it turn golden for the deepest flavor.
Do not overmix: Stir until the flour disappears to keep the bars soft.
Watch the bake time: Pull them when the center looks set. They continue to set up as they cool. This ensures your cookies are chewy!
Use chocolate chunks: Larger pieces melt into gooey puddles! Chopped dark chocolate works well too.
Adjust espresso to taste: we dissolves this into the brown butter for extra flavor. Add more if you want a bolder flavor, instant coffee can work in a pinch but might leave some texture behind.
