Chefadora AI has the answer - timers, swaps, step-by-step help.
In a large microwave-safe mug, whisk flour, sugar, baking powder, and cornstarch until combined.
Stir in melted butter, oil, yogurt, lemon juice, orange juice, and vanilla extract until smooth.
Fold in lemon and orange zest for that bright citrus aroma.
Cook in the microwave for 75–90 seconds, depending on your microwave’s power. The cake should rise and set but remain soft.
Let it sit for 1 minute before frosting or serving.
Mix cream cheese, powdered sugar, and citrus juices until creamy. Spread over cooled cake and garnish with extra zest (optional).
Try powdered sugar dusting, lemon glaze, caramel drizzle, or whipped cream as toppings.
Pair with fresh berries, vanilla ice cream, or a cup of coffee/tea for serving.
Use oat flour instead of all-purpose flour for a healthier option.
Honey or maple syrup can be used instead of sugar for a natural sweetener.
Coconut yogurt can be used for a dairy-free option.
Can I use bottled lemon/orange juice instead of fresh?
Can I use bottled lemon/orange juice instead of fresh?
Fresh is best for flavor, but bottled works in a pinch. Just avoid juices with added sugar or preservatives.
Can I make this mug cake without a microwave?
Yes! You can bake it in an oven-safe ramekin at 350°F (175°C) for about 12–15 minutes.
Can I double this recipe?
Yes — just use two mugs or a larger microwave-safe bowl. Cooking time may increase slightly.
Can I make this mug cake vegan?
Absolutely. Replace butter with vegan butter, yogurt with plant-based yogurt, and you’ll have a vegan-friendly version.
How do I store leftovers?
How do I store leftovers?
This mug cake is best enjoyed fresh, but you can refrigerate it (covered) for up to 24 hours. Reheat for 15–20 seconds before serving.
How do I know when the mug cake is done?
The top should look set but springy to the touch. Insert a toothpick — it should come out mostly clean.
Can I add mix-ins like chocolate chips or nuts?
Definitely! White chocolate chips, chopped almonds, or even dried cranberries pair wonderfully with citrus flavors.
Why did my mug cake turn rubbery?
This usually happens when it’s microwaved too long. Try reducing the cook time by 10–15 seconds.
Can I skip the frosting?
Yes! The cake is delicious on its own. You can also dust with powdered sugar or drizzle a quick lemon glaze.
