Equipment

• One standard 12-ounce microwave-safe mug (ceramic or glass works best)

• Small mixing bowl

• Fork or small whisk

• Measuring spoons

• Spoon

Ingredients

For the Cake:

• ¼ cup all-purpose flour (30g)

• ¼ cup granulated sugar (50g)

• 2 tablespoons unsweetened cocoa powder (10g)

• ⅛ teaspoon baking powder (a tiny pinch)

• Pinch of salt

• 3 tablespoons milk (45ml)

• 2 tablespoons vegetable oil (or melted coconut oil) (30ml)

• ¼ teaspoon vanilla extract

• 1 large egg yolk (discard the white or save for another use)

For the Molten Center:

• 1 to 2 tablespoons chocolate chips (semi-sweet, milk chocolate, or dark chocolate) or a chunk of your favorite chocolate bar.

For Serving (Optional, but Highly Recommended):

• Vanilla ice cream

• A dusting of powdered sugar

• Fresh raspberries or strawberries

Instructions

Part 1: Mix the Dry Ingredients (30 Seconds)

1. Select your mug: Make sure your mug is clean and dry. It’s important that it’s microwave-safe and has enough room for the cake to rise without overflowing. A 12-ounce mug is the ideal size.

2. Combine dry ingredients: Add the flour, granulated sugar, cocoa powder, baking powder, and a tiny pinch of salt directly into the mug.

3. Whisk them together: Use a small fork or a tiny whisk to thoroughly combine all the dry ingredients, breaking up any lumps of cocoa powder or brown sugar. This ensures an even texture.

Part 2: Add the Wet Ingredients (1 Minute)

1. Create a well: Push the dry ingredients to the sides of the mug, creating a small well in the center.

2. Add the wet ingredients: Pour the milk, vegetable oil, and vanilla extract into the well.

3. Add the egg yolk: Carefully add the single egg yolk. The egg yolk is the secret to a rich, tender cake that can support the molten center. The white would make it too foamy and eggy.

4. Mix until just combined: Using your fork, whisk the wet ingredients together in the center first, then slowly incorporate the dry ingredients from the sides. Mix gently until no dry streaks of flour remain. The batter will be thick and glossy. Do not overmix! Overmixing can make the cake tough.

Part 3: Add the Molten Heart (15 Seconds)

1. Hide the chocolate: Take your chocolate chips or chocolate chunk and gently push them into the center of the batter, making sure they are fully submerged and surrounded by batter. They should sit at the very bottom of the mug, not float on top. This is what will create that beautiful, flowing center.

2. The secret for maximum flow: For an even more dramatic lava effect, you can reserve one or two chocolate chips and press them directly into the very top of the batter after you’ve buried the rest. This creates a little extra pocket of melted chocolate near the surface.

Part 4: Microwave to Perfection (1 Minute)

1. Microwave power: Place the mug in the center of your microwave. The key to a perfect lava cake is not overcooking it. Microwave on high power.

2. Timing is everything:

   • Start with 45 seconds for a very gooey, almost entirely molten center. The edges should be set and the top will look slightly moist and underdone.

   • For a more structured cake with a lava center, microwave for 60 seconds (1 minute) . The top should look set and spring back lightly when touched. A slightly undercooked look is what you’re going for.

   • If your microwave is less powerful (under 1000 watts), you may need up to 75 seconds (1 minute 15 seconds) .

3. Check for doneness: The cake will look puffed up and slightly moist on top. If the top looks completely dry and cakey, you’ve likely gone too far, and the center may have baked through. It’s always better to err on the side of less time—you can always add 5-10 seconds, but you can’t “unbake” it.

Part 5: Serve Immediately (1 Minute)

1. Cool slightly: The mug will be very hot! Use an oven mitt or a towel to carefully remove it from the microwave. Let it stand for about one minute. This allows the lava to settle slightly so it doesn’t explode everywhere when you dig in.

2. The grand finale: Place the mug on a small plate. Top with a generous scoop of vanilla ice cream—the cold against the warm cake is divine. Dust with a little powdered sugar and add a few fresh raspberries for a touch of elegance.

3. Dig in: Grab a spoon and dive straight into the center to experience that glorious, molten chocolate flow.

Recipe Notes & Tips

• Doubling the Recipe: To make two, simply double all ingredients and divide the batter between two mugs. Cook them separately, as cooking two at once can be uneven.

• No Egg Yolk? If you don’t want to use an egg yolk, you can substitute it with 1½ tablespoons of milk mixed with ½ tablespoon of melted butter. The texture will be slightly different (a bit more like a pudding cake), but it will still be delicious.

• Flourless Version: For a gluten-free option, you can omit the flour entirely! Mix ¼ cup of cocoa powder with the sugar, then add the wet ingredients. The result is an intensely rich, fudge-like chocolate pudding cake with a molten center. Reduce microwave time to 30-40 seconds.

• Flavor Variations: Get creative! Add a pinch of cinnamon or a drop of peppermint extract to the batter. You can also use caramel-filled chocolate squares, peanut butter chips, or a spoonful of Nutella for the center instead of plain chocolate.

• Safety Warning: The mug will be extremely hot after microwaving. Be careful when handling it, and be sure to warn anyone you’re serving. The melted chocolate center can also be very hot, so allow it to cool for just a minute before enjoying.
