Car Cookies

adapted from Baking Bites
Cookies baked in your car!
Servings 30


  • 1/2 cup 8 Tbsp unsalted butter, softened
  • 1/2 cup light brown sugar lightly packed
  • 1/4 cup vanilla sugar
  • 1 large egg room temperature
  • 1/2 tsp vanilla extract
  • 1/2 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp fine sea salt
  • 1 1/2 cups all purpose flour
  • 1/3 cup mini chocolate chips
  • 1/3 cup Heath bar baking bits


  • In the bowl of a stand mixer, cream the butter and sugars until light and fluffy (about 3 minutes). Add the egg and then the vanilla extract. Distribute around the bowl the baking soda, baking powder, sea salt, and flour. Mix until fully incorporated. Remove bowl from mixer and stir in the chocolate chips and Heath bar bits.
  • Cut 2 pieces of wax paper. Divide the dough in half and on each piece of wax paper, roll out a log of cookie dough about 2″ thick. Wrap and freeze for 2-3 hours.
  • When you have a REALLY hot day (like 100 degrees Fahrenheit), park your car in the sun with the dashboard facing the sun. Line cookie sheets with parchment paper and cut the cookie logs into 1/4″ slices, placing the slices about an inch or two apart on the sheets (they won’t really spread anyway). Put the cookie sheets on your dashboard with pot holders or a towel underneath to protect the dashboard. Close the car up tight and STAY OUT. Just like opening the oven during baking is a no-no, so is opening your doors or windows. Let it be.
  • Leave the cookies for 2 1/2-3 1/2 hours. I know it’s a lot to ask, but it’ll be worth it in the end. They will be firmed up but they will not brown. The centers will hold together but not be firm (unless you want crispy cookies). I put mine in a bit early (10:15AM) so I left them out there for 3 3/4 hours. They were still a bit doughy straight from the car, but they finished up beautifully after sitting out to cool.
  • You can bake just one sheet and save some dough for the next heat wave. The dough will keep in the freezer for up to 3 months. Or you can bake them in your oven at 350 degrees Fahrenheit for 8-10 minutes.
