Ingredients You’ll Need

Gathering the right ingredients is key to getting that perfect balance of fudgy, gooey, and nutty flavors. Each component plays a special role in bringing this Peanut Butter Chocolate Lava Cake to life, whether it’s providing tenderness, richness, or that irresistible molten texture.

• 4 oz semi-sweet chocolate: Choose good quality chocolate to ensure a deep, luscious chocolate flavor that’s not too sweet.
• 2 tbsp unsalted butter: Adds a silky smooth texture and helps melt everything together perfectly.
• 2 tbsp peanut butter: Go for creamy peanut butter for the best molten center that’s nutty and smooth.
• 1/4 cup all-purpose flour: Just enough to hold the cake together while keeping it light and tender.
• 1/4 cup granulated sugar: Adds sweetness without overpowering the chocolate and peanut butter combination.
• 1/8 tsp salt: A pinch to enhance the depth of flavors and balance the sweetness.
• 1 large egg: Binds the ingredients and lends a fluffy structure to the cake’s edges.
• 1/2 tsp vanilla extract: Enhances all the flavors and adds a warm, aromatic note.
• Optional powdered sugar or ice cream: For serving, to add an extra touch of sweetness or creaminess.

How to Make Peanut Butter Chocolate Lava Cake

Step 1: Preheat and Prepare Ramekins

Start by preheating your oven to 425 degrees Fahrenheit (220 Celsius). While the oven warms up, generously grease two small ramekins with butter or non-stick spray, then lightly dust them with flour or cocoa powder. This ensures your Peanut Butter Chocolate Lava Cake will release cleanly once baked, preserving its beautiful shape and molten center.

Step 2: Melt Chocolate and Butter

Place the semi-sweet chocolate and butter in a microwave-safe bowl. Heat them in 20-second bursts, stirring in between to blend everything until smooth and silky. This step is crucial for a glossy, rich base. Then, stir in the peanut butter so it melds into the chocolate mixture, creating that wonderful nutty lava core.

Step 3: Mix Wet Ingredients

In a separate bowl, whisk the egg, granulated sugar, and vanilla extract until the mixture is smooth and slightly pale. This aerates the batter and helps give your lava cake a light, tender crumb on the outside while keeping the center wonderfully soft.

Step 4: Combine All Ingredients

Pour your chocolate-peanut butter mix into the egg mixture and fold gently until combined. Then add the flour and salt, folding just until no streaks remain. Be careful not to overmix — you want a batter that’s silky but still fluffy enough to produce those delightful set edges around the molten center.

Step 5: Bake the Cakes

Divide the batter evenly between the prepared ramekins and bake for 10 to 12 minutes. The edges should be set and cakey, while the center remains slightly soft and jiggles when you gently shake the ramekin. This balance is what makes the Peanut Butter Chocolate Lava Cake so magical — a firm exterior hugging a molten, decadent heart.

Step 6: Serve While Warm

Let the cakes cool for 1 to 2 minutes before carefully inverting each onto a dessert plate. This short resting time allows the lava cake to hold shape but still be warm enough to ooze that luscious peanut butter chocolate filling once cut or broken into.

How to Serve Peanut Butter Chocolate Lava Cake

Garnishes

A light dusting of powdered sugar adds a delicate sweetness and pretty contrast to the rich chocolate tones. Or, for an extra indulgent experience, serve your Peanut Butter Chocolate Lava Cake with a scoop of vanilla or coffee ice cream. The cold creaminess alongside the hot molten center is simply unforgettable.

Side Dishes

Sometimes a simple dessert benefits from a little something on the side. Fresh raspberries or sliced strawberries lend a bright, tart counterpoint that cuts through the richness. A small bowl of whipped cream or caramel sauce can also elevate the dessert to restaurant quality.

Creative Ways to Present

For special occasions, drizzle some melted chocolate or peanut butter sauce over the top. You can also sprinkle with chopped roasted peanuts or a pinch of sea salt for texture and flavor contrast. Serving the Peanut Butter Chocolate Lava Cake in mini cast iron skillets or pretty glass ramekins adds rustic charm and lets you personalize the size according to your crowd.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator. While the molten lava experience will be less gooey, the cake will still taste delicious for up to two days.

Freezing

Peanut Butter Chocolate Lava Cake can be frozen before baking. Simply prepare the batter in the ramekins, cover tightly with plastic wrap and aluminum foil, and freeze for up to one month. When ready, bake straight from frozen; add a couple extra minutes to the baking time for best results.

Reheating

To enjoy the molten center again, gently reheat the cake in a microwave for about 20-30 seconds or until warm but not overcooked. Watch it closely so the center stays soft and gooey — that’s the true joy of this dessert!

FAQs

Can I use crunchy peanut butter instead of creamy?

Yes, but creamy peanut butter melts more smoothly and creates a better molten center. Crunchy ones may cause a slightly textural surprise, which can be delightful if you enjoy the crunch.

What if I don’t have ramekins?

You can use small oven-safe mugs or custard cups as a substitute. Just make sure they are heatproof and greased well to avoid sticking.

Can this recipe be made gluten-free?

Absolutely! Substitute the all-purpose flour with a gluten-free flour blend that measures cup for cup, and you’ll still get delicious results.

Is it possible to make this vegan?

Making this recipe completely vegan is tricky because of the egg, but you can try substituting with a flax egg and vegan butter, plus dairy-free chocolate and peanut butter. The texture may vary but the flavor will still be delicious.

How do I know when the cakes are done?

The edges should be set and look firm, while the center should remain soft and slightly jiggly when you gently shake the ramekin. Do not overbake or the molten center will be lost.
