Step-by-Step Instructions
- Preheat the oven to 375°F (190°C). Line a muffin tin with 9-10 muffin liners and set aside.
- Make the Cinnamon Crumb Topping:
- In a small bowl, whisk together the flour, sugar, and cinnamon.
- Pour in the melted butter and stir with a fork until the mixture becomes crumbly.
- Place the topping in the fridge to chill while you prepare the muffin batter.
- Prepare the Blueberry Muffin Batter:
- In a medium bowl, whisk together the sugar, egg, yogurt, oil, milk, and vanilla until well combined.
- In a separate large bowl, stir together the flour, baking powder, and salt.
- Add the dry ingredients to the wet ingredients and whisk until just combined. Do not overmix—lumps are okay.
- Gently fold in the blueberries.
- Assemble the Muffins:
- Evenly distribute the batter among the prepared muffin liners, filling them almost to the top.
- Remove the cinnamon crumb topping from the fridge and break it into small chunks with a fork.
- Sprinkle about 1 generous tablespoon of crumb topping over each muffin.
- Bake the Muffins: Place the muffin tin in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
- Cool and Serve: Remove the muffins from the oven and let them cool in the tin for 5-10 minutes before transferring to a wire rack. Enjoy warm or at room temperature.
- Storage: Store the muffins in an airtight container for up to 3 days. For longer storage, freeze in an airtight container for up to 8 weeks.
Perfect Pairings: Serving Suggestions
These blueberry muffins are delicious on their own, but they shine even brighter with a few thoughtful pairings. Serve them warm with a dollop of whipped cream or a drizzle of honey for a touch of sweetness. For a breakfast treat, pair them with a hot cup of coffee or a refreshing glass of orange juice. They also make a delightful dessert alongside a scoop of vanilla ice cream.
Keep Them Fresh: Storage and Reheating Tips
Store your muffins in an airtight container at room temperature for up to 3 days. To keep them moist, place a slice of bread in the container—it helps retain freshness. For longer storage, freeze them in a freezer-safe bag for up to 8 weeks. When ready to enjoy, thaw at room temperature or reheat in the microwave for 10-15 seconds for that just-baked warmth.
Mix It Up: Recipe Variations
Feel free to get creative with this versatile recipe! Swap the blueberries for raspberries, chopped strawberries, or even chocolate chips. For a nutty twist, add chopped walnuts or pecans to the batter. If you’re feeling adventurous, try a lemon zest or orange zest infusion for a citrusy kick. The possibilities are endless!
Time-Saving Hacks for Busy Bakers
Short on time? Prep the cinnamon crumb topping the night before and store it in the fridge. You can also measure out the dry ingredients in advance and keep them in a sealed container. If using frozen blueberries, toss them in a bit of flour before folding them into the batter to prevent bleeding and save time on cleanup.
Essential Equipment for Muffin Success
To make these muffins effortlessly, you’ll need a standard 12-cup muffin tin and muffin liners for easy removal. A whisk and mixing bowls are key for combining ingredients, while a fork works perfectly for creating the crumb topping. Don’t forget a toothpick to test for doneness—it’s the baker’s best friend!
