Ingredients You’ll Need

No fancy stuff here—just pantry staples you probably already have. If not, a quick store run won’t kill ya.

4 tbsp all-purpose flour: The backbone of your cake. Nothing fancy, just the regular stuff.
4 tbsp granulated sugar: Sweetens the deal. Don’t skimp here; it’s dessert, not a diet.
2 tbsp unsweetened cocoa powder: Go for the good stuff, not that dusty old can from 2019.
1/8 tsp baking powder: Just a pinch to give your cake some lift.
Pinch of salt: Trust me, it makes the chocolate pop.
3 tbsp milk: Any kind works—dairy, oat, almond, whatever you’re vibing with.
2 tbsp vegetable oil: Keeps it moist (sorry, had to say it).
1/2 tsp vanilla extract: For that extra je ne sais quoi.
2 tbsp chocolate chips: The star of the gooey center. Use semi-sweet or dark, your call.
Optional: 1 tbsp water: For extra fudgy texture, but don’t overthink it.

Grab a microwave-safe mug or ramekin (about 8 oz works best). Pro tip: Spray it lightly with cooking spray to avoid a sticky disaster.

Step-by-Step Instructions

Ready to make magic? Follow these steps, and you’ll be eating lava cake faster than you can say “chocolate coma.”

Mix the dry stuff: In your mug, stir together flour, sugar, cocoa powder, baking powder, and salt with a fork. No lumps allowed—give it a good whisk like you mean it.
Add the wet stuff: Pour in the milk, vegetable oil, and vanilla extract. Stir until smooth. If it looks too thick, add that optional tablespoon of water. Don’t overmix; we’re not kneading bread here.
Drop in the chocolate chips: Sprinkle those bad boys right in the center of the batter. Don’t stir them in—they’ll sink and create that molten core we’re drooling over.
Microwave it: Pop the mug in the microwave and cook on high for 1 minute 30 seconds to 2 minutes. Every microwave is different, so keep an eye on it. The cake should rise and look set on top but still be gooey inside. Don’t overcook, or you’ll end up with a hockey puck.
Let it chill (briefly): Let the cake sit for 1–2 minutes to cool slightly. It’s hotter than your last bad date, so don’t burn your tongue.
Dig in: Grab a spoon and go to town. Optional: Top with a scoop of ice cream or a dusting of powdered sugar if you’re feeling extra.

Common Mistakes to Avoid

Even a recipe this simple has pitfalls. Here’s how to not mess it up:

Overcooking the cake: Microwaving it too long kills the gooey center. Start with 90 seconds and check. You want it slightly underdone for max lava vibes.
Using a tiny mug: If your mug’s too small, you’ll have a chocolate explosion. Use an 8 oz or larger mug to avoid a cleanup nightmare.
Skipping the chocolate chips: They’re the key to the molten center. Don’t sub them with cocoa powder— rookie move.
Not greasing the mug: Unless you want to chisel your cake out, give that mug a quick spray or wipe with oil.
Using old cocoa powder: That ancient canister in the back of your pantry? Toss it. Fresh cocoa makes a big difference.

Alternatives & Substitutions

Life happens, and sometimes you’re missing an ingredient. No stress—here’s how to make it work:

No milk? Swap in water or any non-dairy milk. Coconut milk adds a fun tropical vibe, but don’t go overboard—it’s not a piña colada.
No vegetable oil? Melted butter works, but it’ll taste richer. Margarine? Eh, I wouldn’t, but you do you.
Gluten-free? Use a 1:1 gluten-free flour blend. It’s just as tasty, promise.
No chocolate chips? Chop up a chocolate bar or use a spoonful of Nutella for that gooey center. Hazelnut-chocolate lava cake? Yes, please.
Want it extra indulgent? Stir in a pinch of instant coffee powder with the dry ingredients. It makes the chocolate flavor pop without tasting like a latte.

IMO, the chocolate chips are non-negotiable for that molten core, but if you’re out, get creative. Just don’t tell me you used raisins. We’re not that desperate.

FAQs

Can I double the recipe for two servings?

Sure, but don’t just double it in one mug—unless you want a chocolate volcano in your microwave. Make two separate mugs for best results. Same cooking time, just check both cakes.

Why did my cake turn out rubbery?

You probably overcooked it. Microwaves are sneaky like that. Next time, cut the cooking time by 15 seconds and check for that gooey center.

Can I use margarine instead of oil?

Technically, yes, but why do that to your soul? Oil or butter keeps it moist and flavorful. Margarine’s just… sad.

Can I make this vegan?

Totally! Use non-dairy milk (like almond or oat) and vegan chocolate chips. Double-check your sugar if you’re super strict—some brands aren’t vegan-friendly.

How do I know when it’s done?

The top should look set but slightly jiggly. If it’s rock-hard, you’ve gone too far. Start with 90 seconds and add 10-second bursts if needed.

Can I prep this ahead of time?

You can mix the batter and store it in the fridge for a few hours. Just add the chocolate chips right before microwaving. Fresh is best, though—don’t let it sit too long.

What if I don’t have a microwave?

Sorry, friend, this one’s microwave-only. If you’ve got an oven, try a traditional lava cake recipe. It’s more work, but worth it.
