Introduction
These muffins transform your sourdough discard into a bakery-worthy treat, perfectly balancing tangy, tart, and sweet. You get bursts of fresh cranberries and rich pockets of melted white chocolate in every tender bite. It’s the ultimate way to use your discard without any sourdough flavor dominating the delicious result.
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 12-cup standard 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, whisk the melted butter and granulated sugar together until combined.
- Add the eggs one at a time, whisking well after each addition. Then whisk in the Greek yogurt, buttermilk, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) until smooth.
- Stir the sourdough discard into the wet ingredients until fully incorporated.
- Fold in the fresh cranberries and chopped white chocolate bar pieces.
- Divide the batter evenly among the 12 prepared muffin cups, filling them nearly to the top.
- Bake for 20-23 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
- Allow muffins to cool in the pan 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. Drizzle over the cooled muffins before serving.
Variations
- Jumbo Muffins: Divide the batter into 6-8 jumbo muffin cups and increase bake time by 5-10 minutes.
- Muffin Tops: Spread the batter into a greased muffin top pan for a crispy, bakery-style treat with a shorter bake time (start checking at 15 minutes).
- Streusel Topping: Skip the chocolate drizzle and add a crunchy top by sprinkling a mix of 1/4 cup flour, 1/4 cup brown sugar, and 2 tbsp cold butter rubbed together before baking.
- Individual Loaves: Bake the batter in greased mini loaf pans for a fun, shareable gift.
Tips for Success
- Ensure your buttermilk, yogurt, and eggs are at room temperature to create a smooth, evenly combined batter that rises beautifully.
- Chop the white chocolate bar into small, varied pieces (some fine shards, some chunks) for better distribution and pockets of melted chocolate.
- Fold the batter gently and only until combined. Overmixing leads to dense, tough muffins.
- For easy cranberry distribution and to prevent them from sinking, toss the fresh cranberries in a tablespoon of the measured flour before folding them in.
Storage & Reheating
Store completely cooled muffins in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. For longer storage, freeze them for up to 3 months. Reheat muffins in a 300°F oven for 5-10 minutes or in the microwave for 15-20 seconds to restore a soft, fresh-baked texture.
FAQ
I don’t have buttermilk. What can I use? Make a quick substitute by adding 1/2 tablespoon of white vinegar or lemon juice to a 1/2 cup measuring cup, then filling it the rest of the way with regular milk. Let it sit for 5 minutes before using.
My discard is very thick. Is that okay? Yes, the recipe accounts for various discard consistencies. Just be sure to stir it into the wet ingredients thoroughly until no lumps remain.
Can I use dried cranberries instead of fresh? You can, but the flavor and texture will be different—much sweeter and chewier. If using dried, reduce the amount to 1 cup and consider soaking them in hot water for 10 minutes, then draining, to plump them up.
Why are my muffins dense or gummy? This is usually due to overmixing the batter or using expired baking powder/soda. Ensure your leaveners are fresh and fold the dry ingredients in just until combined.
Can I use all white chocolate wafers instead of a chopped bar? The chopped bar provides irregular, melty pockets, while wafers are designed to hold their shape. For the mix-in, a chopped bar is recommended, but you can use all wafers chopped up if needed.
