Introduction
These muffins transform your sourdough discard into a sweet, tangy, and indulgent breakfast treat. The tart fresh cranberries and rich pockets of chopped white chocolate create a perfect balance of flavors. You’ll get a tender, moist muffin with a slight tang from the discard that makes it anything but ordinary.
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 375°F (190°C). Line a standard muffin tin with 12 paper liners or grease the cups well.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
- In a large bowl, combine the melted butter and sugar. Whisk vigorously for about a minute.
- Add the eggs to the butter mixture and whisk until smooth and slightly thickened.
- Whisk in the Greek yogurt, buttermilk, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) until fully combined.
- Stir in the sourdough discard until the mixture is uniform.
- Fold in the fresh cranberries and chopped white chocolate bar.
- Divide the batter evenly among the 12 muffin cups, filling them nearly to the top.
- Bake for 22-23 minutes, or until the tops are golden and a toothpick inserted into the center of a muffin comes out clean.
- Allow the muffins to cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely.
- If using, melt the white chocolate melting wafers according to package instructions and drizzle over the cooled muffins.
Variations
- Create a streusel topping by combining a few tablespoons of the batter’s dry ingredients with some cold butter and sugar before baking for a crunchy finish.
- For a decorative touch, sprinkle a few extra chopped white chocolate pieces and cranberries on top of the batter before baking.
- Serve warm muffins with a dollop of extra Greek yogurt or a light dusting of powdered sugar.
- For a deeper flavor, let the batter rest for 30 minutes before baking to allow the sourdough discard to activate slightly.
Tips for Success
- Using room temperature ingredients ensures a smooth, even batter and better rise.
- Chop the white chocolate bar into small, uneven pieces for varied pockets of sweetness throughout the muffins.
- If your cranberries are very large, consider halving them to distribute their tart flavor more evenly.
Storage & Reheating
Store muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. To reheat, warm frozen muffins in the microwave for 30-60 seconds or thaw and warm in a 300°F oven for 10 minutes.
FAQ
Can I use frozen cranberries?
Yes, frozen cranberries can be used without thawing. Just add them directly to the batter.
What if I don’t have buttermilk?
You can make a quick substitute by adding 1 teaspoon of lemon juice or white vinegar to 1/2 cup of regular milk and letting it sit for 5 minutes.
Can I use dried cranberries instead?
Dried cranberries will work, but they are sweeter and less tart. You may want to reduce the sugar slightly to balance the flavor.
My discard is very thick. Is that okay?
Yes, any consistency of sourdough discard works, from thick paste to a more liquid batter. Just stir it well into the wet ingredients.
Why are room temperature ingredients important?
Cold ingredients can cause the melted butter to solidify, creating lumps and potentially affecting the texture of the final muffins.
Can I omit the white chocolate drizzle?
Absolutely. The drizzle is purely optional for extra sweetness and decoration. The muffins are delicious without it.
