Ingredients

• Muffins: 1 cup (240 g) mashed ripe bananas (about 2 large), 1/2 cup (120 g) sourdough discard (unfed), 1/2 cup (100 g) granulated sugar, 1/4 cup (60 g) unsalted butter, melted, 1/4 cup (60 ml) vegetable oil, 2 large eggs, 1 tsp vanilla extract, 1 1/2 cups (190 g) all-purpose flour, 1 tsp baking powder, 1/2 tsp baking soda, 1/2 tsp salt, 1/2 tsp ground cinnamon
• Cinnamon Streusel: 1/3 cup (65 g) light brown sugar, packed, 1/4 cup (30 g) all-purpose flour, 1/2 tsp ground cinnamon, 2 tbsp (28 g) unsalted butter, melted, pinch of salt

Instructions

Step 1: Prepare the oven and muffin tin

Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease lightly.

Step 2: Mix the wet ingredients

In a large bowl, whisk together mashed bananas, sourdough discard, sugar, melted butter, oil, eggs, and vanilla until well combined.

Step 3: Combine the dry ingredients

In a separate bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.

Step 4: Fold together

Gently fold the dry ingredients into the wet mixture, mixing just until no dry spots remain (do not overmix).

Step 5: Fill the muffin cups

Divide the batter evenly among the muffin cups, filling each about 3/4 full.

Step 6: Make the streusel

For the streusel, mix brown sugar, flour, cinnamon, melted butter, and a pinch of salt in a small bowl until crumbly.

Step 7: Add the topping

Sprinkle the streusel evenly over the muffin batter.

Step 8: Bake

Bake for 20–22 minutes, or until a toothpick inserted into the center comes out clean.

Step 9: Cool

Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Zusatztipps für die Zubereitung

The key to tender muffins is avoiding overmixing—once the dry ingredients are added to the wet, fold gently just until combined. A few small lumps are perfectly fine. Use very ripe bananas with plenty of brown spots for maximum sweetness and flavor. The sourdough discard should be unfed and can come straight from the refrigerator. When making the streusel, the butter should be melted but not hot, allowing it to form those perfect crumbly clusters. For even baking, rotate the muffin tin halfway through the baking time if your oven has hot spots.

Varianten und Anpassungen

These muffins are wonderfully adaptable. For extra richness, fold in 1/2 cup of chopped walnuts or pecans to the batter before baking. Chocolate lovers can add 1/2 cup chocolate chips for a decadent twist. If you don't have sourdough discard, substitute with an equal amount of Greek yogurt or sour cream. For a dairy-free version, replace the butter with coconut oil and use a plant-based milk. You can also make mini muffins—just reduce the baking time to 12-15 minutes. If you prefer a healthier option, substitute half the all-purpose flour with whole wheat flour and reduce the sugar slightly.

Serviervorschläge

These muffins are delicious on their own, but they're even better when served warm with a pat of butter melting on top. Pair them with a hot cup of coffee or tea for a perfect breakfast or afternoon snack. They make an excellent addition to a brunch spread alongside fresh fruit and yogurt. For a more indulgent treat, split a muffin and spread with cream cheese or Nutella. They're also wonderful packed in lunchboxes or enjoyed as a post-workout snack. Store in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months—just thaw at room temperature or warm briefly in the microwave.
