Peanut Butter Chocolate Lava Cakes
Peanut butter and chocolate are one of the most delicious flavor combinations. Peanut Butter Chocolate Lava Cakes bring the two together for a delectable, molten lava, chocolate dessert.

I love to use the word lava when it comes to these cakes because that’s exactly what you get when you cut into the warm cake, a flow of molten peanut butter and chocolate lava. My mouth is watering as I type this.
Lava Cakes Sweetness
Where this may look like an over indulgent dessert, this is surprisingly low in sugar. In addition, I used half the amount of butter I usually use and replaced it with healthier peanut oil.
Peanuts have a triple feature in this recipe, peanut oil, peanut butter and chopped peanuts so I don’t feel guilty when I need a little sweet fix once in a while.

These mini chocolate cakes with peanut butter filling, make for a fun dessert if you’re entertaining because they come with a wow factor when your guest cut into them. They can be prepared ahead and then only take 10 minutes to bake.
You do want to serve them a few minutes out of the oven, for that lava flow. It’s all about the lava. You may want to make 2 per person, just in case.
Peanut Butter Chocolate Lava Cakes

Warm peanut butter oozes from a chocolate lava cake for a delicious, individual dessert.
Ingredients
- Non-stick cooking spray
- 2 tablespoons unsweetened cocoa powder
- 4 tablespoons 1/2 stick unsalted butter
- 2 tablespoons peanut oil
- 4 ounces (115 grams) 70% dark chocolate
- 2 whole, large eggs, room temperature
- 1/2 cup (100 grams) granulated sugar
- 1/3 cup (46 grams) all-purpose flour
- 1 teaspoon instant espresso powder
- 4 tablespoons creamy peanut butter
- 1/2 cup peanuts, chopped
Instructions
- Preheat oven to 400°F/200°C.
- Spray four, 5 ounce ramekins with non-stick spray. Dust with cocoa powder and tap over the sink to discard any excess. Place them on a baking sheet and set aside.
- Fill a pan with water and heat until low simmer. Set a heatproof bowl on top of the pan (make sure bowl does not touch water). Add the butter, peanut oil and chocolate to the bowl and stir until melted, turn off the heat.
- To a mixing bowl or stand mixer add the eggs, egg yolks and sugar. Beat on low speed for 1 minute then faster speed for 2 minutes until pale and fluffy.
- Pour the melted butter and chocolate slowly into the egg mix while whisking. Add the flour and in small batches, whisking in-between additions, until well combined. Whisk in the espresso powder until blended.
- Fill a ramekin 1/3 full of chocolate mix, add a tablespoon of peanut butter on top, then cover with more chocolate mix. Repeat with all ramekins.
- Place all the ramekins onto a baking sheet and bake in the center of the oven for 10 minutes until the edges look cooked and the centers are sunken and look moist. Remove from oven and allow to cool for 10 minutes in the ramekins.
- To remove from the mold, run a knife around the edge and turn onto a serving plate. Serve immediately with chopped peanuts.

We made these last night and they were tasty! I was a bit confused about where to add in the oil as it wasnt mentioned in the directions, so I put it in with the chocolate. And was also unsure about the peanut butter. It says 4 tablespoons plus 2 tablespoons. But in the directions it only mentions the 4 tablespoons. I did give two of them extra peanut butter as we like peanut butter as a curious experiment, but found that 1 tablespoon was definitely plenty. We love peanut butter and chocolate too, and we had fun making them. I love that it doesnt make a lot of dessert and is relatively simple.
Hi Ashley, thank you so much for the positive feedback. I did just convert to new recipe software and found that some of the recipes did not convert correctly and added text where it shouldn’t be. I’ve edited the recipe to be correct now, I hope you make them again ๐
oh how I wish I could have a bite it looks amazing.
Oh my! This is my idea of HEAVEN, Janette. I’ve always wanted to try making these. You’re right that it’s a really fun thing to have your guests cut into them and all the ‘lava’ runs out!

Oh wow look at that lava cake. It really represents well what it is and I bet it tastes smashing as a dessert for a special Sunday evening. I think my mother in law would be the first to finish it all up. ๐
You do realise you didn’t have to write a thing for this post, just the recipe and that first photo would have done it. That gorgeous lava flowing first photo won me over completely!! Such a wonderful looking recipe and I love the look of those Georgia peanuts as well.
Lava cakes make me weak in the knees – when they are made with peanut butter + chocolate they have double the power. These look incredible – the outside is perfect and such a gooey center! You are spot on “Peanut butter and chocolate are one of the most delicious flavor combinations” ever!
I definitely agree that peanut butter and chocolate are a delicious flavor combination. This cake looks delicious! Love that molten center. Can’t wait to try it!
