Ingredients

• 3 ripe bananas, mashed

• 1/2 cup brown sugar
• 2 eggs
• 1 Tbsp melted butter
• 1/4 cup Greek yogurt
• 1/2 cup sourdough discard or active starter
• 2 tsp vanilla extract

How to Make Sourdough Banana Muffins

Step 1: Preheat the Oven

Preheat your oven to 425°F. Line or grease your muffin tin. I love to use these cupcake papers as it really elevates the look and feel of the muffins.

Step 2: Mix the Wet Ingredients

In a large bowl, mash the bananas until smooth.

Add the coconut sugar, brown sugar, eggs, melted butter, Greek yogurt, sourdough discard, and vanilla. Whisk until fully combined.

Step 3: Add the Dry Ingredients

Add the flour, baking soda, and salt.

Gently stir until just combined. Be careful not to overmix—this keeps your muffins soft and fluffy.

Step 4: Scoop the Batter

Using a 4 Tbsp cookie scoop, divide the batter evenly into your muffin tin.

If you’d like, sprinkle chocolate chips on top.

Step 5: Bake

Bake at 425°F for 5 minutes, then reduce the oven temperature to 375°F and continue baking for 12–15 minutes.

The muffins are done when the tops are golden and a toothpick comes out clean.

Pro Tips for Perfect Muffins

• Don’t overmix the batter – this is key for soft muffins
• Start at a higher temperature – this helps create tall, bakery-style tops
• Use very ripe bananas for the best natural sweetness
• Let muffins cool slightly before removing from the pan

Substitutions & Variations

• No coconut sugar? → Use all brown sugar
• No Greek yogurt? → Substitute sour cream
• Want extra texture? → Add chopped walnuts or pecans
• Love chocolate? → Turn these into chocolate chip banana muffins

How to Store & Freeze

• Store at room temperature in an airtight container for 2–3 days
• Refrigerate for up to 5 days
• Freeze for up to 3 months

To freeze, let muffins cool completely and store in a freezer-safe bag. Reheat in the microwave for a quick, easy snack.

Serving Ideas

• Warm with a little butter
• Paired with your morning coffee
• Packed into lunchboxes for an easy snack
• Served fresh out of the oven for a cozy weekend treat
