Makes 24. Recipe adapted from the Homemade Food Junkie blog.
Ingredients
- 125 g peanut butter
- 55 g butter at room temperature
- 80 g light brown sugar
- 1 teaspoon vanilla extract
- Between 100-300 g discarded sourdough starter1
- 1 egg
- 125 g all-purpose flour
- 0.5 teaspoons (about 3 g) baking powder
- 0.5 teaspoons (about 3 g) baking soda
- Pinch of salt
- Granulated sugar for sprinkling
You’ll also need
- Electric mixer
- One large mixing bowl
- One smaller mixing bowl
Method
- Preheat oven to 175°C.
- In a large mixing bowl, use an electric mixer to mix the peanut butter, butter, brown sugar, and vanilla extract. Beat at medium speed until light and fluffy-looking.
- Mix in the sourdough discard and egg until just combined.
- In the smaller mixing bowl, sift the flour, baking powder, baking soda, and salt until homogenised, ensuring there are no lumps.
- Add the dry ingredients to the wet ingredients in three parts. Gently fold the dry ingredients in until just combined.
- Line your baking tray with baking paper. To shape the cookies, make 2 cm balls out of the dough, lightly roll them around in granulated sugar, and place them 4 cm apart on the baking tray as they will expand during baking. Lightly press them with your fingers to make discs.
- Bake for 10 minutes until cookies are golden-brown. Remove trays from oven and let sit for 5 minutes so the cookies can harden, then move to wire racks to cool.
Footnotes
Less sourdough starter means your cookie will end up more crispy; using more starter means your cookie will be chewier. I think the texture would also vary depending on how active your starter is to begin with, so do experiment!↩︎
