There is nothing better than the smell of brown butter in the kitchen. These cookies combine that nutty flavor with fresh, juicy peaches for a treat that feels like summer in every single bite.

My family loves these because they are soft, chewy, and just a little bit fancy thanks to the icing. Try to use firm peaches so they hold their shape well while the cookies bake.

🧺 Ingredients

1/2 cup unsalted butter
1 cup packed light brown sugar
1/2 cup granulated sugar
1 large egg
1 teaspoon vanilla extract
1 1/2 cups old fashioned rolled oats
1 cup all purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 cup fresh peaches, finely diced
2 tablespoons peach jam
1 cup powdered sugar for the icing
1 tablespoon brown butter for the icing
1 tablespoon milk for the icing

👩‍🍳Instructions

1
Place the butter in a small saucepan over medium heat. Cook it until it turns golden brown and smells nutty, then remove it from the heat and let it cool.
2
In a large bowl, whisk together the cooled brown butter, brown sugar, and granulated sugar until well combined.
3
Add the egg and vanilla extract to the butter mixture and stir until smooth.
4
Mix in the flour, baking soda, and salt. Gently fold in the oats, diced peaches, and peach jam.
5
Chill the dough in the refrigerator for about 30 minutes to make it easier to scoop.
6
Preheat your oven to 350 degrees Fahrenheit and line a baking sheet with parchment paper.
7
Scoop rounded tablespoons of dough onto the baking sheet and bake for 10 to 12 minutes until the edges are golden.
8
While the cookies cool, whisk together the powdered sugar, a tablespoon of brown butter, and the milk to make the icing.
9
Drizzle the icing over the cooled cookies before serving.

💡 Tips

Store these cookies in an airtight container at room temperature for up to three days. If you want to keep them longer, you can freeze the unbaked dough balls and bake them fresh whenever a craving hits.
