It’s a common misconception to think all baked treats are unhealthy. Yes, many treats on store shelves, bought in bakeries, and in premade mix form are riddled with additives and excessive sugar. But you can make a heathier baked good at home using wholesome ingredients.

That’s one of the main reasons I started my sourdough starter. It adds gut health to our food as well as combines well with many other wholesome ingredients.

I’m always using my sourdough starter to try something new or whip up our favorite treats. This past year we’ve been loving cinnamon rolls, brownies, scones, cookies, and even Danishes. They always taste amazing and I feel good serving them to those I love. So let’s dive in to one of our recent favorites, this sourdough brownie recipe!

Sourdough Brownies Recipe Inspiration

Over the past year I would come across sourdough brownie recipes every now and then while browsing on Pinterest. But I never thought of creating one of my own until a recent visit to my dentist.

While getting my biannual cleaning my dental hygienist began chatting about her sourdough starter. Long story short we got on the subject of sourdough brownies.

She said her boyfriend thinks sourdough brownies are the best brownies he’s ever had. After hearing how delicious they were I got inspired to go home and create my own recipe. A version for me and my family to treasure.

Helpful Tips

Cut After Cooled: Wait 5-10 minutes after you pull the brownies out of the oven to cut into them. It ensures a clean cut so they’re not a mess.

Stir Only To Combine: Don’t overmix the batter, just stir to combine.

Get Eggs to Room Temperature: Let your eggs sit 30 minutes on the counter before using them so they can come to room temperature. This allows your brownies to bake evenly (cold eggs can take longer for the batter to bake)

Ingredients

  • 8 Tbsp butter
  • 1 cup semi-sweet chocolate chips
  • 1/4 cup pure cane sugar
  • 2 eggs
  • 1 tsp pure vanilla extract
  • 1/2 cup sourdough starter (fed or discard)
  • 1 Tbsp cocoa powder
  • 1/2 cup all-purpose flour
  • 1 tsp salt
  • extra 1/4 cup semisweet chocolate chips (to stir in batter)

Recipe FAQ

Is it unsafe for eggs to sit out on the counter for 30 minutes?

Eggs are safe to sit out for 2 hours or 1 hour if the temperature is above 90 outside (tip from Southern Living)

How long do eggs need to sit out to come to room temperature?

It takes about 30 minutes for them to get to room temperature. If you’re running short on time, you can put them in a bowl of warm water (not hot) for 10 minutes.

Do I have to let my eggs come to room temperature before baking brownies?

You don’t have to but it’s a recommended best practice. I used to be the same way, I never wanted to let them sit out but I researched a little and it really does make a difference. The cold egg causes the batter to take longer to bake.

Can you make these sourdough brownies long ferment?

Yes, but you don’t have to. Just cover the batter and pop it into the fridge overnight or up to 24 hours. This long ferment will develop a stronger sourdough flavor and creates easier digestion when you eat them.

Is it best to use fed sourdough starter or sourdough discard for brownies?

You can use either one! It doesn’t really matter.

How can I make my brownies more fudgy?

Adding more fat, like butter, than flour will create a fudgy brownie instead of a cake-like consistency.

What can I do with a lot of sourdough starter?

Oh boy you can do tons! You can make these brownies, artisan bread, same day bread, dinner rolls, waffles, pancakes, and more.

How do I know when brownies are done?

Sourdough brownies will be set around the edges but look slightly underbaked in the center when ready. Once you pull them out of the oven they’ll finish baking in the pan while cooling. This is why you need to let them cool before cutting.

What type of flour is best for brownies?

An all-purpose flour is best when baking brownies because it gives them a light texture. I prefer the unbleached organic type.

What kind of cocoa powder is best for brownies?

I like using regular cocoa powder made by Hershey’s for brownies. I’ve tested a few other brands but they don’t have the same chocolatey flavor.

Do you have to use brown sugar in brownies?

Some recipes do but mine doesn’t. Brown sugar can make the brownies more fudgy but it also makes them much more sugary.

Do I have to use parchment paper for brownies?

That’s a personal opinion. Many people do but some don’t. If I have some on hand I’ll use it for easy cleanup and ease of moving the brownies. But when I don’t I just grease the pan with butter.

Can I freeze fresh baked brownies?

You’ll want to let the brownies cool to room temperature before freezing them.

How do you make a sourdough starter?

I’m glad you asked! I’ve got the perfect starter recipe here on Plum Branch Home. If you’d like extra assistance with the process or feel overwhelmed checkout my free DIY sourdough starter course. I walk you through each step day by day in your email.

Can I put pecan pieces in this brownie recipe?

Yes, you can add pecan pieces to this brownie recipe. Just stir them in with the rest of your ingredients.

Should I just leave the brownies in the pan and put them in the fridge once they cool off?

I always put them in an airtight container once cooled but you can also keep them in the pan and cover with wrap. They’ll last about 2-3 days on the counter or a week in the fridge.

    Great Brownie recipe!! Just the right sweetness and richness.
    I didn’t have the semisweet chocolate chips so I used the milk chocolate ones. I just used less cane sugar. Turned out so delicious!
    I’ll be making these again and again!!

    1. Thank you so much!! I’m so happy you loved them and great idea for how you substituted the semisweet chocolate chips 😊
