FAQs

What kind of cocoa powder should I use?

Use unsweetened natural cocoa powder for the best flavor and texture in this recipe.

Can I use chocolate chips instead of chunks?

Yes, chocolate chips work just as well and will still provide a delicious chocolate bite.

How can I make these muffins more moist?

Ensure you don’t overbake the muffins and use whole milk and oil as directed for moisture.

Can I use buttermilk instead of regular milk?

Yes, buttermilk can add a tangy richness and tender texture to the muffins.

How do I know when the muffins are done baking?

Insert a toothpick into the center; if it comes out clean or with a few moist crumbs, they’re done.

Can I make this recipe gluten-free?

Yes, use a 1:1 gluten-free flour blend designed for baking to substitute the all-purpose flour.

What’s the best way to mix the batter?

Should the eggs be at room temperature?
