Sourdough Peppermint Brownies

| |

Nothing says Christmas time quite like peppermint and chocolate in my opinion! These peppermint brownies are so delicious and will be the center of attention at your next Holiday party!

My favorite candy bar is the peppermint patty. I will never turn one down, ha ha. These brownies pay homage to that candy bar but are much healthier since I’m using freshly milled flour and wholesome ingredients. I add a bit of sourdough starter to mine for the flavor, however, you can omit this if you wish.

I always try to make some special treats for the Christmas season. And, as much as we enjoy sweets, we realize we need to make them as natural and wholesome as possible. Freshly milled flour and raw sugar give these brownies a lot of nutrition without sacrificing the taste.

You can serve these brownies to your guests without worrying they will think they are “healthy”. These are so delicious and make the perfect dessert for your holiday parties!

Of course if you want to use store bought flour, you definitely can. You can do a long ferment with the sourdough as well if you wish. I just did the quick version.

For this recipe you will need:

  1. Flour
  2. Cocoa
  3. Sugar
  4. Eggs
  5. Baking soda
  6. Baking powder
  7. Salt
  8. Peppermint extract
  9. Vanilla extract.
  10. Sourdough starter

Preheat the oven to 350 degrees F.

In a large mixing bowl add the flour, cocoa, sugar, baking powder, baking soda, and salt. Mix well.

In a separate bowl, add eggs, vanilla, peppermint extract, and sourdough starter. Mix well.

If you want to do a long ferment, add the flour, cocoa, and sourdough starter, and eggs to the mixing bowl and mix well. Cover and allow to sit out for an hour then move to the fridge overnight, up to 24 hours.

Add to dry ingredients and mix well.

Add to an 8.5×8.5 baking dish that has been sprayed with oil and dusted with flour.

Bake for 20-25 minutes.

    These brownies were so fun to bake at Christmas time. I am always looking for ways to use my sourdough starter to minimize discard.

  2. I am making the brownies – the batter is really dry – I added about 3 T of water – was there supposed to be some oil in the recipe? Looking forward to trying these – finally a recipe with no butter! Thank you.

    1. I didn’t add the oil since there was 3 eggs. I would just add enough water to make it the right consistency. Every flour is different as far as how it absorbs liquids.

      1. Thank you – the mixture you poured into your bowl was super moist – they are really tasty! Thank you so much for your recipes & instructions!
