Prep & Cook Time
Prep Time: 15 minutes
Cook Time: 12 minutes
Total Time: 27 minutes
Servings: 24 mini muffins
Ingredients
- 1 cup plus 2 tbsp all-purpose flour
- 1 ½ tsp baking powder
- 1/2 tsp salt
- ⅔ cup mini semi-sweet chocolate chips (plus more for topping)
- ¼ cup unsalted butter (room temperature)
- ¼ cup granulated sugar
- ¼ cup light brown sugar
- 2 tsp orange zest
- 1 large egg (room temperature)
- 1 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 1/3 cup buttermilk (room temperature)
- ¼ cup turbinado sugar – for topping
Instructions
- Preheat your oven to 375°F (190°C). Line a 24-cup mini muffin tin with paper liners or grease thoroughly.
- In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Add ⅔ cup of the mini chocolate chips and toss to coat in the flour mixture (this helps prevent them from sinking).
- In a separate large bowl, use an electric mixer or a sturdy whisk to cream together the room-temperature butter, granulated sugar, and light brown sugar until light and fluffy, about 2 minutes.
- Beat in the orange zest, room-temperature egg, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) until fully combined and smooth.
- Divide the batter evenly among the prepared mini muffin cups, filling each about ¾ full.
- Sprinkle the tops generously with additional mini chocolate chips and the turbinado sugar.
- Bake for 10-12 minutes, or until the tops are lightly golden and a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
- Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Glaze Drizzle: For a bakery-style treat, drizzle the cooled muffins with a simple orange glaze made from powdered sugar and fresh orange juice.
- Lemon Twist: Swap the orange zest for an equal amount of lemon zest for a brighter, tangier flavor profile.
- Streusel Topping: Skip the turbinado sugar and top the batter with a quick crumble of flour, brown sugar, and cold butter before baking.
- Serve Warm with Dip: Serve warm muffins with a side of whipped mascarpone or vanilla yogurt for dipping.
Tips for Success
- Room Temperature is Key: Having your butter, egg, and buttermilk at room temperature ensures they emulsify properly, creating a smoother, more even batter and a better rise.
- Don’t Overmix: Mix the batter until the dry ingredients are *just* incorporated. Overmixing develops gluten, leading to dense, tough muffins.
- Prevent Sinking Chips: Coating the chocolate chips in the flour mixture before adding them to the wet batter helps suspend them in the batter during baking.
- Check Early: Ovens vary, so start checking for doneness at the 10-minute mark to avoid overbaking.
Storage & Reheating
Store cooled muffins in an airtight container at room temperature for up to 3 days. For longer storage, freeze them for up to 3 months. To reheat, warm a muffin in the microwave for 10-15 seconds or in a 300°F (150°C) oven for 5-8 minutes until just warmed through.
FAQ
Can I use regular-sized chocolate chips?
Yes, you can, but mini chips are recommended as they distribute more evenly in the small muffins. If using regular chips, consider chopping them slightly.
What can I use if I don’t have buttermilk?
Make a quick substitute by adding 1 teaspoon of white vinegar or lemon juice to 1/3 cup of regular milk. Let it sit for 5-10 minutes until slightly curdled before using.
My muffins didn’t dome. What happened?
This is often caused by overmixing the batter, or the oven temperature being too low. Ensure your baking powder is fresh and your oven is fully preheated.
Can I make the batter ahead of time?
It’s best to bake the muffins immediately after mixing. Letting the batter sit can cause the baking powder to activate prematurely, resulting in less rise.
Why is room-temperature butter important?
Room-temperature butter creams together with the sugars more effectively, trapping air and creating a lighter, fluffier muffin texture.
Can I use a different sugar for the topping?
Turbinado sugar is ideal for its large crystals and crunchy texture. Coarse sanding sugar is a good substitute. Regular granulated sugar will not provide the same crunch.
