The Best Sourdough Discard Triple Chocolate Loaf (Super Moist & Fudgy)

If you bake sourdough at home, you probably hate throwing away discard. Good news — this Sourdough Discard Triple Chocolate Loaf is one of the most delicious ways to use it!

This cake is:

• Deeply chocolatey

• Incredibly moist

• Slightly fudgy like brownies

• Soft for days

• Perfect with tea or coffee

The sourdough discard doesn’t make the cake sour — instead it enhances the chocolate flavor and gives a rich bakery-style texture you simply can’t get from a regular chocolate cake.

Once you try it, this will become your favorite discard recipe.

Why You’ll Love This Recipe

Unlike dry chocolate loaf cakes, this one stays soft for 4–5 days because sourdough naturally improves moisture retention.

What makes it special:

• Cocoa powder = chocolate flavor

• Melted chocolate = richness

• Chocolate chips = melty pockets
  ➡️ That’s why it’s called triple chocolate

And the sourdough discard acts like buttermilk, creating a tender crumb.

Ingredients

Dry Ingredients

• 1 ¼ cups (160g) all-purpose flour

• ½ cup (50g) cocoa powder

• 1 tsp baking powder

• ½ tsp baking soda

• ½ tsp salt

• ¾ cup (150g) sugar

Wet Ingredients

• ½ cup (120g) sourdough discard (unfed)

• 2 eggs (room temperature)

• ½ cup (120ml) oil

• ½ cup (120ml) milk

• 1 tsp vanilla extract

• 100g melted dark chocolate

Chocolate Add-Ins

• ½ cup chocolate chips

• ¼ cup white or milk chocolate chips (optional)

Step-by-Step Instructions

1. Prepare the Oven

Preheat oven to 170°C / 340°F
Line a loaf pan with parchment paper.

2. Mix the Wet Ingredients

In a large bowl whisk:
eggs + sugar + oil until smooth and glossy.

Add:
milk + vanilla + sourdough discard + melted chocolate

Mix until fully combined.

3. Combine the Dry Ingredients

In another bowl whisk together:
flour, cocoa powder, baking powder, baking soda and salt.

4. Make the Batter

Add dry ingredients into wet mixture.

Gently fold until just combined.
Do not overmix — this keeps the cake soft.

Fold in chocolate chips.

The batter will be thick. That’s normal.

5. Bake

Pour into prepared loaf pan.

Bake for 45–60 minutes

A toothpick should come out with moist crumbs, not wet batter.

6. Cooling (Very Important)

Let cool in pan 15 minutes
Then transfer to rack and cool completely

➡️ The loaf becomes fudgier as it rests!

Optional Chocolate Ganache (Highly Recommended)

Heat 80 ml cream and pour over 80 g chocolate.
Stir until smooth and pour over cooled loaf.

Instant bakery-style finish ✨

Usually overmixing or underbaking.
