What Ingredients You Will Need

This recipe relies on straightforward ingredients that come together to create a rich, gooey dessert with minimal effort. Most are pantry staples, and substitutions are easy if you want to tweak it.

• All-purpose flour – 4 tablespoons (about 30 g), the base for the cake’s structure
• Cocoa powder – 2 tablespoons (unsweetened, for that deep chocolate flavor)
• Sugar – 3 tablespoons (granulated or fine sugar works fine)
• Baking powder – 1/4 teaspoon (helps the cake rise just enough)
• Milk – 3 tablespoons (whole milk preferred for richness, but any milk or dairy-free milk will do)
• Vegetable oil – 2 tablespoons (neutral flavor, but melted butter works if you want extra richness)
• Vanilla extract – 1/4 teaspoon (adds depth to the flavor)
• Salted caramel sauce – 2 tablespoons (I love the brand Trader Joe’s or homemade if you’re feeling fancy)
• Chocolate chips or chunks – 2 tablespoons (semi-sweet or dark chocolate, depending on your preference)
• A pinch of salt (balances the sweetness and enhances the salted caramel)

Substitutions: Use almond flour for a gluten-free twist, and swap dairy milk with oat or coconut milk if you prefer dairy-free. For the salted caramel, you can substitute with dulce de leche or a thick honey drizzle, but the saltiness is what really makes this cake sing.

Equipment Needed

• Microwave-safe mug: Around 12 ounces capacity to prevent overflow. I learned the hard way that smaller mugs make a mess!
• Measuring spoons and cups: Precision matters for baking, even in mug cakes.
• Mixing spoon or small whisk: For combining ingredients smoothly.
• Microwave: Obviously essential. If you don’t have one, a toaster oven or conventional oven can work, but the cooking times will differ.

For budget-friendly options, I’ve used simple ceramic mugs from thrift stores that handle microwave heat well. Avoid metal or mugs with metallic paint. Also, if you want to get fancy, a small silicone spatula helps scrape the mug clean and can double as a cute tasting spoon.

Preparation Method

1. Mix the dry ingredients: In your microwave-safe mug, combine 4 tablespoons (30 g) of all-purpose flour, 2 tablespoons of unsweetened cocoa powder, 3 tablespoons of sugar, 1/4 teaspoon baking powder, and a pinch of salt. Stir well to blend, ensuring no lumps remain. This usually takes about 1 minute.
2. Add the wet ingredients: Pour in 3 tablespoons (45 ml) of milk, 2 tablespoons (30 ml) of vegetable oil, and 1/4 teaspoon of vanilla extract. Stir gently until you get a smooth batter with no dry patches. The batter should be thick but pourable.
3. Prepare the lava center: Spoon 2 tablespoons of salted caramel sauce into the middle of the batter in the mug. Using the back of a spoon, gently push the caramel down just a bit but don’t mix it in. Sprinkle 2 tablespoons of chocolate chips over the top to add extra melty pockets.
4. Microwave carefully: Place the mug in the microwave and cook on high for 60 to 70 seconds. Microwave powers vary, so start with 60 seconds and add 5-second bursts if needed. The edges should be set but the center slightly jiggly — that’s your molten lava.
5. Let it rest: Allow the mug cake to cool for 1-2 minutes. This helps the lava center thicken slightly but stay gooey. Don’t skip this step, or you’ll burn your tongue (been there!).
6. Enjoy immediately: Grab a spoon, and when you cut into the cake, the salted caramel lava should ooze out like a warm, silky river of yum.

Pro tip: If the cake looks dry or overcooked, your microwave probably runs hot. Try reducing the time by 5 seconds next time and keep an eye on that jiggle. Also, a mug with straight sides works better for even cooking than a wide bowl.

Cooking Tips & Techniques

Let me share a few nuggets I’ve picked up along the way to make your decadent salted caramel chocolate lava mug cake foolproof:

• Don’t overmix your batter: Stir just enough to combine. Overmixing can make the cake tough or rubbery.
• Use good quality cocoa powder: It makes a world of difference in flavor. I’m a fan of Valrhona or Hershey’s Special Dark for that rich chocolate punch.
• Watch your microwave time closely: Microwave ovens vary wildly, so test in short increments. The perfect mug cake is all about slightly undercooking the center for that lava effect.
• Salted caramel is your secret weapon: The salt cuts through the sweetness and adds complexity. If you’re using store-bought, taste-test it first to avoid overly sweet or runny caramel.
• Multitasking tip: While the cake cooks, prep your toppings or cold milk glass so you’re ready to enjoy the moment.
• Mess alert: Some mug cakes expand during cooking, so place your mug on a microwave-safe plate to catch any overflow. Learned this the messy way once!

Variations & Adaptations

Want to switch things up or accommodate dietary needs? Here are some tasty twists I’ve tried and loved:

• Peanut Butter Lava: Replace the salted caramel with a tablespoon of creamy peanut butter for a nutty surprise inside.
• Vegan Version: Use almond or oat milk, swap oil for melted coconut oil, and choose dairy-free chocolate chips and caramel. It’s just as indulgent!
• Spiced Chocolate: Add a pinch of cinnamon or cayenne pepper to the batter for a subtle warmth that pairs beautifully with the caramel.
• Berry Bliss: Drop a few fresh or frozen raspberries on top before microwaving for a tart contrast.
• Gluten-Free: Use a gluten-free flour blend equal to 4 tablespoons. Make sure your cocoa powder is gluten-free certified.

My personal favorite variation is adding a sprinkle of flaky sea salt on top after cooking—it gives that extra crunch and a pop of saltiness that makes each bite unforgettable.

Serving & Storage Suggestions

This decadent salted caramel chocolate lava mug cake is best enjoyed warm and fresh, straight from the mug. The molten center is the star, and it starts to set as it cools.

Pair it with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent treat. A cold glass of milk or a cup of coffee complements the rich chocolate beautifully.

If you have leftovers (rare, but it happens!), cover the mug tightly with plastic wrap and store in the refrigerator for up to 24 hours. Reheat in 15-second bursts in the microwave, checking frequently to avoid overcooking.

Flavors deepen after resting a bit, but the lava center will firm up, so fresh is best. If you want to prep this ahead, keep the batter ready in the mug (without cooking) and refrigerate for up to a day, then microwave when ready.
