🧈 Ingredients
Here are the ingredients needed to make these double chocolate chip muffins.

Ingredient Notes
- Butter - As in most of my recipes I use salted butter in these muffins. You can replace it with unsalted butter. Simply add an additional ¼ teaspoon of salt to the recipe.
- Sugar - A combination of white and brown sugar makes for a great texture and flavor!
- Cocoa - For a rich and chocolatey flavor without bitterness, I like to use Dutch-processed cocoa. I buy this organic Rodelle cocoa at Costco!
- Semisweet Chocolate - These muffins have melted chocolate in the batter and chocolate chips folded in for an extra dark and rich muffin.
- Sour Cream - Adds moisture and richness!

📃 Instructions

Step 1: In a heat-safe bowl, melt the butter and chocolate chips in the microwave in 15-second increments.

Step 2: Whisk the melted butter and chocolate chips until smooth before whisking in the brown sugar and white sugar.

Step 3: Add the eggs, vanilla, sour cream, and milk and whisk until smooth.

Step 4: In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.

Step 5: Add the dry ingredients and chocolate chips to the wet ingredients and whisk just until incorporated. Do not overmix!

Step 6: Distribute the batter between each cup in a prepared muffin tin, filling each about to the top with the batter.
Bake in a 400℉ preheated oven for 5 minutes before reducing heat to 350℉ for another 10-12 minutes or until a toothpick comes out clean. Let cool in the muffin tin for about 10 minutes before transferring to a wire rack to finish cooling.
💡 Top Tip
Be very careful not to overmix or overbake muffins. Overmixing will result in muffins that are tough and dense. Overbaking will make muffins turn out dry and crumbly. Avoid these disappointing results by mixing just until the dry ingredients are incorporated and baking just until a tester inserted into the center of a muffin comes out without any wet batter (a few moist crumbs is okay!).

❓ Recipe FAQs
Yes, you can, but be advised that the muffins may turn out slightly less moist as Greek yogurt has less fat than sour cream.
I haven't tested this recipe with gluten-free ingredients, but I would love to know how it goes if you try it!
Store fully cooled muffins at room temperature in an airtight container with a piece of paper towel on the bottom to absorb excess moisture so that the muffin tops don't become soggy. Or freeze in an airtight container or Ziplock bag for up to 4 weeks.
