Wet Ingredients
- 8 Tbsp Butter, softened (120 grams)
- 1 cup Brown sugar (144 grams)
- 2 Eggs (about 100 grams)
- 2 Bananas, mashed
- 1¼ tsp Vanilla (7 grams)
Dry Ingredients
- 1¼ cups All purpose flour (168 grams)
- 1 tsp Baking powder (5 grams)
- ¾ tsp Salt (4 grams)
Streusel Topping
- ¼ cup All purpose flour (38 grams)
- ¼ cup Brown sugar (38 grams)
- 3 Tbsp Butter, cold and cut into cubes (38 grams)
- ⅓ cup Walnuts (38 grams)
- 1 pinch Salt
Optional Add-ons
- ¼ cup sourdough discard (leave out if you don’t have a sourdough starter)
- Prepare the streusel topping: In a small bowl, mix the cold cubed butter, ¼ cup all purpose flour, ¼ cup brown sugar, ⅓ cup walnuts, and a pinch of salt using your fingers. Incorporate until small clumps form. Cover and refrigerate the mixture until ready to top the muffins.
- Preheat the oven: Set your oven to 350°F (175°C) and allow it to preheat fully for even baking.
- Cream butter and sugar: In a large bowl or stand mixer, beat together the 8 Tbsp softened butter and 1 cup brown sugar using a handheld or stand mixer for about 2 minutes until the mixture is combined and fluffy.
- Add eggs and vanilla: Crack in the 2 eggs and add 1¼ tsp vanilla extract. Mix gently until just combined to avoid over-beating.
- Incorporate dry ingredients: In a separate bowl, whisk together 1¼ cups all purpose flour, 1 tsp baking powder, and ¾ tsp salt. Slowly fold these dry ingredients into the wet mixture with a rubber spatula, mixing gently to prevent over-mixing the batter.
- Add sourdough discard: If using, gently fold in the ¼ cup sourdough discard with the spatula until incorporated evenly.
- Add mashed bananas: Gently fold in the mashed bananas into the batter, again being careful to not over-mix to keep the muffins tender.
- Prepare muffin tins: Cut parchment paper squares taller than your muffin insert to create liners, or use regular muffin papers. Place liners into muffin tins. This recipe makes 7 regular-sized muffins or 6 jumbo muffins.
- Fill muffin cups: Spoon the batter into the muffin liners, filling each about two-thirds full. Then evenly sprinkle the chilled streusel topping on each muffin.
- Bake the muffins: Place the muffin tin in the middle rack of the preheated oven. Bake at 350°F (175°C) for 28-30 minutes, or until a toothpick inserted in the center comes out clean.
- Cool and serve: Allow the muffins to cool in the tin for a few minutes before transferring to a cooling rack. Serve warm or at room temperature.
- Storage: Store muffins in an airtight container at room temperature for up to two days. For longer storage, individually wrap each muffin in plastic wrap and freeze for up to one month.
Notes
- Using a kitchen scale to weigh ingredients ensures accuracy and consistent results, but measuring cups can be used as well.
- Do not over-mix the batter as it can make the muffins tough instead of tender and moist.
- The optional sourdough discard adds a subtle tang and improves texture but can be omitted if unavailable.
- Make sure the butter for the streusel topping is cold to create the perfect crumbly texture.
- Using parchment paper liners taller than the muffin tins helps hold the batter and streusel topping neatly.
