Equipment
- 1 Large Bowl
- 1 9x11 aluminum baking pan
Ingredients
- 3/4 cup melted butter 165 grams
- 3/4 cup brown sugar 134 grams
- 1/2 cup sugar 100 grams
- 1 egg
- 1 egg yolk optional, see notes
- 2 tsp vanilla 8 grams
- 1/2 cup sourdough discard 110 grams
- 2 cups flour 280 grams
- 1 tsp baking soda 6 grams
- 1 tsp salt 7 grams
- 1.5 cups chocolate chips I use a mix of mini chocolate chips and regular sized semi sweet
Instructions
- Line a 9x11 inch metal pan with parchment paper.Melt the butter in a large, microwave safe bowl for about 20 seconds at a time, stirring as you go. If the butter is very hot, let it cool for a few minutes.
- Add the brown sugar, sugar, egg, egg yolk, and vanilla to the melted butter and mix well with a spatula. Stir in the sourdough discard.
- Add the flour, baking soda, and salt to the wet ingredients and mix with spatula. Stir in the chocolate chips until just combined.
- Spread the dough evenly throughout the parchment lined pan. Cover with plastic wrap and refrigerate for at least 30 minutes.
- Preheat oven to 350 degrees F and bake the bars for 18-22 minutes, or until the edges are just slightly brown. The middle will look under baked but will firm up when cooling.
- Cool the entire pan on a wire cookie rack, then slice and enjoy! Makes 24 bars.
Notes
- For the best results measure your flour with a kitchen scale.
- An extra egg yolk makes these bars chewy and thick - omit if you must, but it does help the texture!
- Melt the butter at 15 second intervals, stirring between each time, to avoid over heating the butter.
- If the butter is very hot let it cool before adding in the eggs.
- I used sourdough discard that was about 18 hours old for this recipe. You can substitute active starter if needed, just stir it down.
- Ferment the dough for up to 72 hours in the fridge.
- To store: let the bars cool completely and transfer to an airtight container at room temperature for 3-5 days.
