Tips for Preparing to Make These Cookies
- Chill the Dough: I HIGHLY recommend chilling the dough for at least 1 hour best results. I typically chill mine overnight and bake the next day. If chilling overnight, set out the bowl of cookie dough to thaw on the counter before trying to scoop and shape the cookies. Letting the dough come to room temperature makes this process much easier.
- Baking: I always like to slightly underbake my cookies in order to obtain a chewier texture. They will continue to cook briefly on the cookie sheet once they are pulled out of the oven.
- Don’t skip out on the additions of the egg yolk and cornstarch. They help to make a much chewier, softer cookie!
- Variations: Feel free to experiment with different flavors. Adding in chopped pecans or using dark chocolate chips would be delicious. If you love sweet and salty, topping the cookies with a light sprinkle of flaky sea salt is also delicious!
- If you don’t own a stand mixer, you can still easily make this recipe using a large bowl and an electric handheld mixer.

Step by Step Instructions
- In the bowl of a stand mixer fitted with a paddle attachment or a medium bowl, cream together softened butter and brown sugar until combined.
- Beat in the egg, egg yolk, sourdough discard, and vanilla extract until light (about 1 minute).
- Begin adding in the dry ingredients, mixing until combined.
- Add in the toffee bits and mix well.
- Add the dough to the fridge to chill for a minimum of 1 hour and up to overnight.
- Once ready to bake, preheat oven to 375 degrees F. Prepare two baking sheets by lining them with parchment paper or a silpat baking mat. Set aside.
- Using a medium sized cookie scoop, scoop out 12 equal balls of cookie dough onto each prepared cookie sheet.
- Bake in preheated oven for approximately 10-11 minutes. Take them out when they are just barely starting to turn golden brown.
- For best results, let them sit on the baking pan for 5 minutes before removing to a wire rack to cool.
- Baked cookies will store well in an airtight container for up to 5 days. Enjoy!

How to Make Buttered Maple Icing
Optional but definitely delicious, this maple glaze is the same one I use in this sourdough chocolate chip scone recipe. It comes together quickly using just a few ingredients. To make it, you will need:
- 6 tbsp butter
- 1/3 cup maple syrup
- 1 tsp vanilla extract
- good pinch of salt
- 1 1/4 cup powdered sugar
- In a small saucepan over medium heat, add in the butter and maple syrup, whisking until the butter has completely melted and combined with the syrup.
- Remove from heat and add in 1 tsp of vanilla extract, pinch salt, and powdered sugar. Whisk together until completely smooth.
- Pour the glaze over the cooled cookies. Enjoy!
Recipe FAQs & Storage Tips
Yes! These cookies can be made ahead of time and placed in the freezer until ready to bake. My method for this is to scoop out balls of cookie dough and add them to a gallon sized freezer safe bag, making sure I store the bag laying flat in the freezer. Once you are ready to bake, you can pop the cookies straight from the freezer into the oven, or set out on the counter to thaw beforehand. If you are putting them straight in the oven from the freezer, you may need to adjust your baking time to allow the frozen dough extra time to bake.
These cookies store well at room temperature on the counter for up to 3 days, or an airtight container for up to 5 days. If you haven’t heard of the bread trick, definitely try it. Simply add a small slice of bread to your container to keep your cookies extra soft!
Keep in mind that at the end of the day, it is still a cookie recipe that contains sugar and fats. However, sourdough is a great option because the long fermented grain is more easily digested and utilized. It also adds more flavor to any recipe.
