How to Make Easy Chocolate Muffins

These come together in minutes and they're so easy! You'll wonder why you didn't think of this before!

1. Preheat oven to 350°F. Line a muffin tin with cupcake liners.
2. Mix the batter: In a large bowl, combine cake mix, eggs, melted butter, and milk. Stir until smooth.
3. Add chocolate chips: Fold in the mini chocolate chips.
4. Make the streusel: In a small bowl, mix brown sugar, flour, and cocoa powder. Cut in cold butter with a fork until crumbly.
5. Fill muffin cups: Scoop batter into liners, filling almost to the top for bakery-style muffins.
6. Add streusel topping: Sprinkle chocolate streusel generously over each muffin.
7. Bake: Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool and enjoy: Let cool slightly before serving.

Tips for Bakery-Style Muffins

• Fill cups nearly full for tall muffin tops
• Add a few extra chocolate chips on top before baking
• Use liners for easy removal
• Don’t overmix

Storage

Store in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. Muffins can also be frozen.

What to Expect from these Muffins

First of all, how have I not tried this before? I have a double dark chocolate espresso muffin recipe on this site but it's a from-scratch version. Why haven't I turned a chocolate cake mix into a muffin before tonight? I honestly don't know, but I'm glad the idea finally came to me!

I'm taking these to my grandkids tomorrow and I feel sure they will love them. I hope you do, too.

Thanks for stopping by!

👩‍🍳 About the Baker

If there’s one thing I’ve learned in the kitchen, it’s this: you don’t have to start from scratch to make something truly special.

At Out of the Box Baking, I’m all about taking simple ingredients—like a basic cake mix—and turning them into something that feels homemade, bakery-style, and completely worth sharing.

I didn’t set out to become a “cake mix baker,” but somewhere along the way I realized that with a few thoughtful tweaks, you can create rich, delicious recipes without the fuss. That’s where the magic happens.

And honestly? That’s how most of my recipes come together. I use what I have, make a few adjustments, and trust the process.

If you’re the kind of baker who wants great results without overcomplicating things, you’re in the right place.
