Prep & Cook Time
Prep Time: 5 minutes
Cook Time: 23 minutes
Total Time: 28 minutes
Servings: 12 muffins
Ingredients
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup melted butter (salted)
- 1 cup granulated sugar
- 2 large eggs (room temperature)
- 1/2 cup full-fat Greek yogurt (room temperature)
- 1/2 cup buttermilk (room temperature (see note))
- 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 1 cup sourdough discard
- 1 1/2 cups fresh cranberries
- 4 ounces white chocolate bar (chopped)
- 4 ounces white chocolate melting wafers (optional, for drizzling over muffins)
Instructions
- Preheat your oven to 425°F (220°C). Line a standard 12-cup muffin tin with paper liners or grease it thoroughly.
- In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
- In a large mixing bowl, combine the melted butter and granulated sugar. Whisk vigorously for about one minute until well blended.
- Add the room-temperature eggs one at a time, whisking well after each addition until the mixture is smooth and slightly pale.
- Whisk in the Greek yogurt, buttermilk, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) until the wet ingredients are fully combined.
- Stir in the sourdough discard until just incorporated into the wet mixture.
- Gently fold in the fresh cranberries and chopped white chocolate bar until just evenly distributed throughout the batter.
- Divide the batter evenly among the 12 prepared muffin cups, filling each to the top.
- Place the muffin tin in the preheated oven and immediately reduce the oven temperature to 400°F (200°C). Bake for 18-23 minutes, or until the tops are golden and a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs (avoid testing directly into melted chocolate).
- Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
- If using, melt the white chocolate melting wafers according to package instructions. Drizzle the melted chocolate over the cooled muffins.
Variations
- For a streusel topping, combine 1/4 cup each of flour, brown sugar, and cold cubed butter with a pinch of cinnamon before baking.
- Make mini muffins for a party by reducing the bake time to 12-15 minutes.
- Create a citrus twist by adding the zest of one orange to the wet ingredients for a bright flavor boost.
- Serve them warm as a dessert by splitting a muffin and topping it with a scoop of vanilla ice cream.
Tips for Success
- Ensure your buttermilk, yogurt, and eggs are truly at room temperature to help the batter combine smoothly and rise evenly.
- Tossing the cranberries in a tablespoon of the measured flour before folding them in can help prevent them from sinking to the bottom.
- The initial high oven heat helps create a nice domed top on the muffins, so be sure not to skip the temperature reduction step.
Storage & Reheating
Store cooled muffins in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. To reheat, warm a muffin in the microwave for 15-20 seconds or in a 300°F oven for 5-10 minutes until just heated through.
FAQ
Can I use frozen cranberries?
Yes, you can use frozen cranberries without thawing them. There’s no need to adjust the bake time.
My discard is very thick. Is that okay?
Yes, sourdough discard can vary in hydration. As long as you measure it by volume (1 cup), any standard consistency will work in this recipe.
What can I use if I don’t have buttermilk?
You can make a quick buttermilk substitute by adding 1 1/2 teaspoons of white vinegar or lemon juice to 1/2 cup of regular milk. Let it sit for 5 minutes before using.
Can I make these muffins ahead of time?
Absolutely. The batter can be prepared, portioned into the muffin tin, covered, and refrigerated overnight. Bake directly from the fridge in the morning, adding 1-2 extra minutes to the bake time if needed.
Why did my muffins turn out dense?
This is usually due to overmixing the batter, which develops the gluten in the flour. Fold the dry ingredients in gently and stop as soon as no flour streaks remain.
Can I omit the white chocolate?
Yes, you can leave it out. The muffins will be more tart from the cranberries, so you may want to increase the sugar slightly if you prefer a sweeter result.
