How to Make Blueberry and White Chocolate Muffins
Be sure to see the recipe card for the full list of ingredients and detailed recipe instructions.
Combine the dry ingredients in a large mixing bowl.
Combine the melted butter with the sour cream, buttermilk, eggs, vanilla bean paste and vanilla extract. Whisk until well combined.
Pour the wet ingredients into the dry ingredients. Mix until just combined. Gently fold in the white chocolate chunks and frozen berries.
Line your 12-cup muffin pan with muffin liners. Scoop muffin batter into each muffin cup. Fill to the top. Add a scoop of white chocolate streusel to the tops of the muffins.
Bake muffins at 425° for 5 minutes. Lower the oven temperature to 375° and bake for 16-18 minutes more. Serve these dreamy homemade muffins with a warm mug of coffee and enjoy.
Hint: The streusel can get a little messy and sometimes drip onto your oven while the muffins are baking. Be sure to put a large baking sheet underneath your muffins pan while the muffins are baking.
Amanda's Muffin Baking Tips
Bake at a Higher Temperature for the First Five Minutes: To guarantee big, fluffy, bakery-style muffins, bake the muffins for five minutes at a higher temperature - 425°. Then lower the temperature for the rest of the baking time to 375°.
Toss Your Berries in Flour: Even though you have frozen the berries, they will quickly become soft again. Toss the berries in a tablespoon of flour before adding the berries to the muffin batter. This will prevent the blueberries from breaking apart and from sinking to the bottom of the muffins or making your muffins soggy.
Use Muffin Papers or Grease Your Muffin Pan: Muffins sticking to the pan? Try using paper liners or greasing your muffin tin. If you choose to grease your pan, be sure to use plenty of cooking spray or butter to grease your muffin pan.
How to Store Muffins
Leftover muffins should be stored in the refrigerator in an airtight container for 2-3 days. You can also freeze the muffins in an air tight container for up to 2 months. If you freeze baked muffins, I recommend wrapping each one individually in parchment paper and then storing in a freezer bags or container.
Blueberry and White Chocolate Muffins FAQs
Yes! Frozen blueberries work for this recipe. Because frozen berries can become wet, they can make your muffins mushy. To avoid this, toss the frozen berries in a tablespoon of flour before adding them to your muffin batter.
I like baking muffins at two different temperatures. Starting muffins at a higher temperature (425°) gets the batter to rise quickly and helps create a taller muffin top. After five minutes at 425°, lower the oven temperature to 375° and bake for an additional 16-18 minutes. You will have tall, fluffy muffins with a perfectly tender texture.
I like using a chopped up white chocolate bar for this recipe. White chocolate chips will also work. Use high-quality chocolate like Lindt or Ghirardelli for better flavor.
Insert a toothpick into the center-if it comes out clean or with a few crumbs, they're ready.
