4 Ingredient Molten Nutella Lava Mug Cake

This single serving molten Nutella lava mug cake couldn’t be easier. The recipe is just four ingredients and eggless. Hopefully you will love me and not hate me for this one.

I love molten chocolate cakes. For me, my ideal lava cake has a very light, delicate cake shell, with a hot, molten, liquid center.  This is exactly how this cake turns out. And it’s Nutella flavored, which just makes it even more amazing.

This is not your traditional molten cake. A traditional molten chocolate cake involves eggs and creating a chocolate pudding-like batter. This cake actually starts with my 4-Ingredient Nutella Mug Cake. It seems like ages ago when I shared that recipe. I owe a lot to that recipe. I probably wouldn’t have a cookbook out if it wasn’t for that recipe.

One big difference between this and my other mug cakes is that we’re baking this one. Yes, I’m really sorry. Your cake won’t be ready in one minute. But it’s worth the additional 16 1/2 minutes, I promise.

Microwave cooking is quick and easy, but it has its limitations. A true molten lava cake has such a delicate exterior which can only be achieved through a slower cooking process. I didn’t want this to just taste like an underbaked cake, or a cake with some melted chocolate squares in the middle, or a cake with a scoop of Nutella in the middle. I wanted it to really taste like the lava cakes you order for dessert at a restaurant.

And this cake really does. You bake it just until the exterior is cooked but the center isn’t quite finished. When it first comes out of the oven, it might look like a regular cake except for the darker, still slightly sunken center, but within a few minutes, the middle sinks and the edges puffs up, much like traditional lava cakes. The outside of the cake comes out a light, delicate, cake shell. When you peel away that first layer, you’re greeted to a liquid center. It’s amazing on its own or with a scoop of your favorite ice cream.


Update! Recipe now includes video. For the video, I made this in a ramekin but you can also use a mug. You can also find all my latest recipes on my new youtube channel.

5 from 2 votes


  • 4 tbsp all purpose flour
  • 1/4 tsp baking powder
  • 1/4 cup Nutella
  • 3 tbsp fat free milk


  • Preheat oven to 350°F. In an oven-safe mug (it won't rise too high, so an 8-oz is fine), add all four ingredients. Mix with a mini whisk vigorously until batter is completely mixed and smooth.
  • Place mug on a baking sheet and then place into oven. Bake for approximately 16-18 minutes (mine took exactly 17 1/2 minutes). Watch the cake carefully towards the end. You want the cake to have puffed up except the center, which should still look dark and not completely set (but no longer wet, like photo above). Let cake cool a few moments before eating. You can top with powdered sugar and eat with ice cream if desired.

  1. I actually x5 this recipe and made it as a cake for my uncle’s 50th birthday. Everyone loved it and I was just 12 so this is really delicious, simple and easy to make.

  2. I made it for my uncle’s birthday by x4 the recipe.
    Everyone loved it.
    I also made it in the microwave though I used whole milk.
    This is my go-to mug cake recipe now.

  3. I made this and it’s delicious! It is very rich so I would probably make a smaller batch but I love it! Excellent use of Nutella.

  4. Can I make this with no baking powder ?

  5. I just made this.  I didn’t feel like waiting on the oven so I cooked mine in the microwave.  Four tbsp. flour, 4 tbsp. Nutella, 1/4 tsp. baking powder and 3 tbsp. 2% milk.  Fifty seconds in my microwave and it was perfect.  While it was still warm, I spread the top with another spoonful of Nutella.  Yum!

    • glad you liked it! this was originally based off of my microwave cake version. The microwave version is great, just not quite as good at achieving that molten center.

  6. Can i make it in a muffin cup ?????  And will i have to change the oven timings and temp?! ????

  7. Can I make this on stove in cooker? And 1/4 cup rounds upto only 2-3 tbs probably?

  8. How can I make this with a gluten free flour? 

  9. I am making this for guests tonight. Can I make the batter and let it sit then put it in the oven later on? Do I leave it in the fridge or is countertop fine? 

    • I’m sorry I couldn’t answer you sooner. You can probably let it sit for a while but it may need to be restirred before going in the oven. Countertop should be fine.

  10. I made this last night because it was Father’s Day and there are only two of us – I wanted it to be as festive as I could without baking an entire cake. It works beautifully! I didn’t have oven safe mugs so I used Pyrex measuring cups. We gilded the lily and added a scoop of ice cream and a squirt of whipped cream. It’s nice to have a recipe that makes a small amount so I don’t have a whole tempting cake laying around the house.
