Quick answer

Whisk melted butter, sugar, eggs, cocoa, flour, and sourdough discard, portion into a mini muffin tin, and bake until the centres are just set.

Why brownie bites are useful

Sourdough discard adds moisture and a faint depth of flavour to these small brownies. Since the recipe gets its lift from the eggs and does not rely on fermentation, it is a quick option for feeding day. Mini portions also make it easier to stop baking at the fudgy stage.

Ingredients

  • 180 g sourdough discard
  • 100 g unsalted butter, melted

  2. 02
    Whisk melted butter and sugar, then mix in eggs, vanilla, and discard.
  3. 03
    Sift in cocoa, flour, and salt. Stir only until no dry patches remain.

    Cool in the tin for 10 minutes so the bites firm without drying out.

Tips for a fudgy texture

  • Do not overbake; a toothpick should show moist crumbs, not come out completely clean.
  • Use cocoa powder without added sugar so the sweetness stays balanced.
  • Let the brownies cool before judging the texture—the centres set as they rest.
  • Use chopped chocolate for small melted pockets.

Troubleshooting

Bites are dryWhy: They stayed in the oven too long or were too small.Try: Check a few minutes early and remove them when the middle is barely set.
They sink in the middleWhy: The centres were very underbaked or the eggs were not incorporated evenly.Try: Add one or two minutes and whisk the wet mixture until smooth.
Batter is too thickWhy: Discard consistency varies and the flour may have been packed.Try: Add one tablespoon of milk and mix gently.

Storage

Keep brownie bites in an airtight container at room temperature for three days or refrigerate them for up to five days. They freeze well for one month; thaw at room temperature.

Frequently asked questions

Can I bake this in a normal square tin?

Yes. Use a lined 20 cm square tin and bake for about 20–25 minutes, checking for moist crumbs in the centre.

Does the discard need to be active?

No. Fresh unfed discard from a healthy starter is perfect. It should not have mold, pink or orange streaks, or an unpleasant rotten smell.
