Instructions
Melt butter and oil on medium-low heat. Add chocolate chips.
Whisk until fully incorporated.
Add eggs, vanilla, sugars, sourdough discard. Mix.
Add flour, cacao powder, milk powder, and cornstarch. Mix until combined and place in a parchment paper-lined baking dish. Place into oven at 350 fahrenheit.
Hint: For the fudgiest brownies, take them out of the oven when there is a subtle and firm jiggle to the center. You don't want them to be underdone, but a little jiggle will make for the fugiest brownies ever! They will finish baking in the pan outside of the oven and won't be overdone or dry. Wins all around!
Substitutions
- Butter - instead of regular unsalted butter, try a non-dairy butter like Country Crock's Plant Butter Sticks. Note: these sticks contain salt, so you might need to adjust the amount of salt you add to the recipe. Try ½ or ¾ tsp instead of 1 tsp.
- Milk powder: Feel free to omit the milk powder if you'd like to make this dairy-free.
- Flour: Try a 1:1 gluten-free flour. I haven't tried this myself, but I'm sure this would be a good substitute!
Variations
- Add chocolate chips, walnuts, peanut butter, or pecans to give these brownies a fun twist!
Equipment
- Mixing bowl or stand mixer
- 9x9 pan
- Parchment paper
Storage
Cover with cling wrap and leave on the counter for 2-3 days or in the fridge for 5-7 days.
These sourdough brownies stand up well to freezing for 6 months.
Top tip
Allow the brownies to cool fully before cutting for best results.
Use parchment paper to make it easier to remove brownies from the dish.
FAQ
Shiny tops come from high-fat contents in the batter. This is why we use melted butter, oil, melted chocolate, and more egg yolks to whites.
