🧾 Mug Cake Ingredients
You probably already have everything you need for this chocolate mug cake. Here’s what to grab:

- Flour: I use all-purpose flour for this easy chocolate mug cake recipe, but self-rising or cake flour works too.
- Sugar: Granulated sugar adds sweetness and balances the cocoa powder’s bitterness, boosting the flavor.
- Baking Powder: This helps the cake rise and become fluffy.
- Cocoa Powder: Unsweetened cocoa powder gives the cake its rich chocolate flavor and dark color.
- Milk: I use room-temperature whole milk to keep the cake moist and tender, and to blend the dry ingredients smoothly.
- Vegetable Oil: It adds moisture and keeps the cake from drying out, while letting the chocolate flavor shine.
- Chocolate: I like dark chocolate for extra gooey bursts of flavor throughout the cake.

💭Tips for Recipe Success
Use a Microwave-Safe Mug: Pick a mug that's big enough to handle the cake rising without overflowing.
Mix Well: Combine the dry ingredients first to evenly spread the baking powder and cocoa powder before adding the wet stuff. This helps the cake rise evenly.
Smooth Batter: Stir everything together until the batter is smooth and lump-free for even cooking.
Adjust Time: Microwaves vary, so start with 1 minute and 20 seconds. If needed, add extra time in 10-second bursts, keeping an eye on it.
Rest Time: Let the cake cool for 1-2 minutes before digging in. This helps it set and makes it easier to enjoy.
