In a large microwave-safe mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt until well combined and no lumps remain. A fork works well for this.
Add the milk, vegetable oil, vanilla extract, and almond extract to the mug. Stir with the fork until the batter is smooth.
Gently fold in the chocolate chips and diced strawberries, ensuring they are evenly distributed throughout the batter.
Microwave on high for 1 minute to 1 minute and 30 seconds, or until the mug cake is set and a toothpick inserted into the center comes out clean. Start with 1 minute and add 30-second increments as needed.
Let the mug cake cool for a minute or two before enjoying. This allows the flavors to meld and prevents burning your mouth.
For an extra touch of elegance, top with a dollop of whipped cream, a drizzle of melted chocolate, or a few extra fresh strawberry slices.
