Ingredient List (for 12 large muffins)

• ½ cup unsalted butter (≈115 g), softened
• 1½ cups white sugar
• 2 tsp vanilla extract
• 2 large eggs
• 1 cup milk (or plant-based alternative)
• ¾ cup sourdough discard or active starter
• 4 tsp baking powder
• 3 cups all-purpose flour

For the cinnamon sugar filling + topping

• 1½ cups brown sugar
• 5 Tbsp flour
• 4 tsp ground cinnamon
• 6 Tbsp butter, melted

Vanilla glaze

• ⅔ cup powdered sugar
• 1 tsp vanilla extract
• ½-1 Tbsp milk

Instructions

1. Preheat & Prep Liners
   Preheat your oven to 350°F (175°C). Use large bakery-style paper muffin liners (tulip style if possible) in muffin tin. The liners help muffins rise tall and hold their shape.
2. Make the Cinnamon Sugar Mixture
   In a bowl, whisk together brown sugar, flour, and ground cinnamon. Pour in melted butter and mix until crumbly and saturated. Set aside. This will be used for filling and on top.
3. Prepare the Muffin Batter
   In another large mixing bowl, cream softened butter and white sugar until light and fluffy. Add vanilla extract, eggs, milk, and sourdough starter/discard. Mix until combined. Then sift in baking powder and flour; stir gently until just combined. Over mixing can make muffins tough.
4. Layer Batter + Filling
   Spoon batter into muffin liners, filling to about halfway. Add a portion of cinnamon sugar mixture into each. Top with more batter until near top. Finally, crumble and press the rest of cinnamon sugar mixture onto each muffin top. Ensures gooey sugar center and crunchy top.
5. Bake
   Bake for 25-30 minutes at 350°F (175°C), until muffin tops are golden brown and a toothpick inserted in the center comes out clean. Avoid over-baking to prevent dryness.
6. Make the Glaze & Cool
   While muffins cool, whisk powdered sugar, vanilla extract and milk (start with ½ Tbsp milk, then add more until glaze is desired consistency). Once muffins are slightly cooled but still warm, drizzle glaze over top. Let set.

Serving Suggestions

• Serve warm with a cup of coffee or tea. The sugar glaze pairs especially well with light roast coffee.
• For brunch, pair with fresh fruit (berries, sliced peaches) to balance richness.
• Add a dollop of whipped cream or crème fraîche (or coconut whipped cream) on top.
• Also great with a scoop of vanilla ice cream when cooled for dessert.

Expert Tips for Best Muffins

• Use room temperature ingredients (butter, eggs, milk) so batter mixes evenly and bakes uniformly.
• Don’t skimp on the bakery-style liners tall liners allow batter to rise high without spilling.
• Measure flour by weight if possible. Spoon & level method avoids packing too much flour, which could make muffins dry.
• Resting the batter a few minutes before baking helps cinnamon sugar filling settle but avoids sugar sinking.
• Use sourdough starter/discard that is fresh, active, not overly sour (for better flavour balance).

Storage & Shelf Life

• Store muffins in airtight container at room temperature for up to 3 days. Warm briefly before eating.
• They’re best eaten within the first day for texture and moisture.
• You can freeze individual muffins once fully cooled. Wrap in cling film + foil, freeze. Thaw at room temp or warm in oven.

Frequently Asked Questions (FAQ)

Q: Can I use sourdough discard instead of active starter?
A: Yes. This recipe is explicitly designed to work with either sourdough discard or active sourdough starter. The flavor might be slightly milder if using discard, but the texture remains buttery and moist.

Q: What if I don’t have bakery-style/tulip muffin liners?
A: Use regular muffin liners or lightly grease muffin tin. Muffins won’t rise as tall, and edges might bake differently. For regular liners, bake smaller muffins (≈24 muffins) and reduce baking time to ~15-20 minutes.

Q: Can I use a plant-based alternative for butter or milk?
A: Yes. Use solid plant-based butter or margarine and a plant milk (almond, oat, soy) for a dairy-free version. Texture will vary slightly.

Q: How do I prevent the bottom of muffins from being soggy or sticking?
A: Ensure muffin tin is properly lined or greased. Don’t over-fill liners. Bake on middle rack. Use liners that are strong/good quality so they can release heat properly.
