Ingredients

• 4 Tbsp all‑purpose flour (or gluten‑free blend)
• 4 Tbsp granulated sugar (or coconut sugar)
• 2 Tbsp unsweetened cocoa powder
• 1 tsp espresso powder (optional, boosts chocolate depth)
• 1 egg large (or ¼ cup unsweetened applesauce for vegan)
• 3 Tbsp milk (dairy or almond/ oat)
• 3 Tbsp melted butter (or coconut oil)
• ½ tsp vanilla extract
• ¼ tsp baking powder
• Pinch of sea salt
• 2 Tbsp semi‑sweet chocolate chips (for the molten core)

How to Make the Mug Cake

1. Gather your tools. You’ll need a large (12‑oz) microwave‑safe mug, a small whisk or fork, and a microwave set to high power.
2. Combine dry ingredients. In the mug, whisk together flour, sugar, cocoa powder, espresso powder, baking powder, and a pinch of salt until there are no lumps.
3. Add the wet base. Crack the egg into the mug (or add applesauce for a vegan version) and stir in milk, melted butter, and vanilla extract. Mix until a smooth batter forms; the batter should be thick but pourable.
4. Insert the chocolate core. Drop the chocolate chips into the center of the batter, gently pushing them a little below the surface. This ensures a molten center when cooked.
5. Microwave the cake. Place the mug in the microwave and cook on high for 60‑75 seconds. Start with 60 seconds; if the top is still wet, add 10‑second intervals. The cake should rise, and the edges will look set while the centre remains slightly jiggly.
6. Check for doneness. The surface should be firm to the touch, but a gentle wobble in the middle is perfect—it will become a silky lava when you cut into it.
7. Let it rest. Allow the mug cake to sit for 30 seconds; it continues to cook slightly from residual heat.
8. Serve & enjoy. Run a thin knife around the edge, then invert the mug onto a plate (optional) or simply dig in with a spoon. Top with a dusting of powdered sugar, a scoop of vanilla ice cream, or a drizzle of caramel if desired.

Pro Tips & Tricks

• Don’t over‑cook. Microwaves vary; over‑cooking turns the lava into a dry cake. Aim for a slightly under‑done centre.
• Use a silicone mug. Silicone resists heat better than ceramic, reducing the risk of cracking.
• Room‑temperature butter. Melted butter should be warm, not hot, to avoid cooking the egg prematurely.
• Flavor boost. Add a pinch of cayenne or a few drops of orange zest for an unexpected twist.
• Make it extra gooey. Increase chocolate chips to 3 Tbsp or insert a small square of chocolate bar in the centre.

Variations & Substitutions

Storage & Reheating

If you need to make the batter ahead of time, store it in an airtight container in the refrigerator for up to 24 hours. Give it a quick stir before microwaving. Cooked mug cakes are best enjoyed fresh; however, you can refrigerate leftovers for up to 48 hours. To reheat, microwave on medium power for 20‑30 seconds. The lava may become less fluid, so consider adding a fresh drizzle of chocolate sauce before serving.
