Microwave Chocolate Lava Cake

You ever have one of those nights where you want dessert right now, but you’re not about to bake a whole cake or clean more than one bowl? Enter: Microwave Chocolate Lava Cake. It’s rich, gooey, ready in 5 minutes, and you don’t even have to put on pants to make it. Legendary.

This isn’t some sad, rubbery mug cake pretending to be something else. No, this is the real deal: soft chocolate cake on the outside, warm molten center in the middle. All made in a mug. In your microwave. In literal minutes. What a time to be alive.

Why It Slays

Let’s just break it down:

• Single serving – portion control… or make two. Up to you.
• Microwave-only – no oven, no baking drama.
• Molten center – gooey, chocolatey perfection.
• 5-minute dessert – yes, including clean-up time (unless you’re extra messy).

Oh, and no one will know it came from a microwave unless you brag about it. (Which you will. And should.)

Ingredients

• 1/4 cup semi-sweet chocolate chips or chopped chocolate
• 2 tablespoons unsalted butter
• 1 egg
• 2 tablespoons sugar
• 1 tablespoon all-purpose flour
• Optional: a pinch of salt, splash of vanilla extract

Pro Tip: You can add a piece of dark chocolate or a truffle in the center before cooking for next-level lava vibes.

Instructions

Step 1: Melt Chocolate + Butter

• In a microwave-safe mug or small bowl, combine the chocolate and butter.
• Microwave in 20-second intervals, stirring between each, until melted and smooth.

Step 2: Add the Rest

• Add the egg, sugar, flour, and optional vanilla/salt to the chocolate mixture.
• Stir until fully combined. You want a smooth, thick batter.
• (Optional: stick an extra chunk of chocolate in the center for even more gooey magic.)

Step 3: Microwave It

• Microwave on high for 45–60 seconds. It should rise slightly, look set on top, but still be a little soft in the middle.
• Less time = more lava. More time = firmer cake. Watch closely—microwaves can be chaotic.

Step 4: Let It Sit (Just for a Sec)

• Let it rest for about 30 seconds. It’s molten. You don’t want to burn your taste buds off in your enthusiasm.

Step 5: Serve & Swoon

• Top with whipped cream, a scoop of vanilla ice cream, or dust with powdered sugar.
• Then dig in and try not to cry from joy.

Common Mistakes (And How to Avoid Dessert Disasters)

1. Overcooking.
It’s a microwave cake, not a brownie. Pull it when it looks slightly underdone in the center—it’ll finish cooking as it rests.

2. Skipping the chocolate quality check.
Use the good stuff. The better the chocolate, the better the lava. Don’t go Dollar Store for this one.

3. Using the wrong mug.
Use a microwave-safe mug or ramekin. No metallics. Nothing too small—it needs room to rise without exploding like a chocolate volcano.

4. Not mixing well.
Lumpy batter = weird texture. Mix it until it’s totally smooth before you zap it.

Fun Variations to Try

• Peanut Butter Lava Cake: Drop a spoonful of peanut butter in the center before microwaving. Yes. Please.
• Salted Caramel: Add a dollop of caramel sauce inside and finish with flaky sea salt.
• Mint Chocolate: Add a drop of mint extract or a square of mint chocolate in the center.
• Mocha Lava Cake: Stir in 1/4 teaspoon of instant coffee granules for that espresso twist.

FAQ

Can I make this without eggs?
Yep—replace the egg with 2 tablespoons of milk + 1 tablespoon of oil. It won’t be as rich, but still very tasty.

How do I know when it’s done?
The top should look just set, the center should jiggle slightly, and the sides should pull away a bit. Go by look, not exact time—microwaves are all different.

Can I prep it ahead of time?
Sure—mix the batter and store it (covered) in the fridge for a few hours. Just microwave when you’re ready to impress yourself.

What size mug should I use?
At least 8 oz (standard coffee mug size) so it doesn’t overflow. Go bigger if you want breathing room.

Can I double the recipe?
Yes, but don’t cook it in the same mug—it won’t cook evenly. Make two separate cakes instead.
