Ingredients
- 3 tbsp wheat flour
- 1 tbsp granulated sugar
- 1 tbsp unsalted butter
- 1 large egg
- ½ medium apple (e.g., Granny Smith or Fuji)
- 1 tsp fresh lemon juice
- ¼ tsp baking powder
- ¼ tsp ground cinnamon
- Pinch of salt
Note: The original recipe also mentions 1 tbsp milk in the mixing step; you can add it if you prefer a slightly richer batter, though it's optional. For high-quality tools that make measuring a breeze, check our best glass mixing bowls and best oil sprayer for greasing the mug.
Step-by-Step Instructions
- Prepare your mug and workspace. Choose a large microwave-safe mug—at least 350 ml capacity—to allow room for rising. Do all mixing in a separate bowl to ensure a smooth batter. Best wall oven microwave combos with air fryer can also handle mug cakes with extra features.
- Mix dry ingredients. In a clean, dry bowl, sift together the wheat flour, baking powder, ground cinnamon, and salt. Stir with a whisk or fork to combine. For precision, a best planetary mixer can handle larger batches later.
- Prepare the apple. Wash, peel, and core half an apple. Grate it on the large holes of a box grater. Immediately toss with the lemon juice to prevent browning. Set aside. If you prefer a finer texture, a best food processor for nut butter can also grate apples quickly.
- Melt butter and beat egg-sugar mixture. Place the butter in a small microwave-safe bowl and melt on high for 20–30 seconds. In another bowl, whisk the egg and sugar until light and fluffy—an immersion blender or hand mixer works fastest. For best results, try a non-toxic immersion blender for efficient whisking.
- Combine wet and dry ingredients. Allow melted butter to cool slightly, then stir it (and optional milk) into the egg-sugar mixture. Add the grated apple and mix. Gradually fold in the dry ingredients until just combined—do not overmix. Work quickly to keep the batter airy. A best espresso machine under 2000 isn't needed here, but a steady hand is.
- Fill the mug. Pour the batter into the prepared mug, filling no more than two-thirds full to allow for rising. If the batter reaches the rim, transfer to a larger mug or bowl to prevent overflow during cooking. Always use microwave-safe ceramic or glass mugs.
- Microwave the cake. Place the mug in the center of the microwave and cook on high (800W) for 2 minutes. Cooking time may vary by microwave wattage—start with 1 minute 30 seconds if unsure, then add time in 10-second increments. The cake is done when a toothpick inserted in the center comes out clean. For consistent results, a best refrigerant leak detector isn't relevant, but a reliable microwave is—see our microwave pressure cooker guide for more.
- Finish and serve. Carefully remove the hot mug (use an oven mitt). Let cool for 1–2 minutes. Dust with powdered sugar, drizzle with jam, condensed milk, or caramel sauce. Enjoy straight from the mug! For a pairing idea, try with a glass of best organic vodka or a sweet wine from our best sweet wine list.
Tips for the Perfect Mug Cake

Frequently Asked Questions
Can I make this mug cake without a microwave?
Yes, you can bake it in a preheated oven at 180°C (350°F) for 12–15 minutes in an oven-safe mug or ramekin. The texture will be slightly different but equally delicious.
Why did my mug cake turn out rubbery?
Overmixing the batter can develop gluten, leading to a tough texture. Mix only until the dry ingredients are incorporated. Also, avoid overcooking—test at 1 minute 45 seconds if your microwave is powerful.
Can I scale this recipe for two or more people?
Absolutely. Simply double the ingredients and divide the batter into two mugs. Increase microwave time by about 30 seconds to 1 minute, checking doneness with a toothpick.
Is this recipe suitable for kids?
Yes, kids love it! The recipe uses basic ingredients and is low in sugar compared to many store-bought desserts. Supervise when using the microwave. For fruit-forward alternatives, see our total bowel release health guide.
What can I use instead of wheat flour?
Oat flour, almond flour, or a gluten-free all-purpose blend work well. Note that almond flour may yield a denser cake. Adjust liquid if needed.
How do I store leftover mug cake?
This dessert is best enjoyed fresh, but you can store it in the refrigerator for up to 24 hours. Reheat in the microwave for 15–20 seconds. For longer storage, freeze the batter in a sealed container for up to a month.
Can I use a different type of apple?
Yes, but choose firm, moderately sweet apples like Honeycrisp, Braeburn, or Pink Lady. Softer apples like McIntosh may break down too much. For more fruit ideas, check our best castor oil (unrelated but part of the link set).
Why is milk mentioned in the steps but not in ingredients?
The original recipe may have an omission. Adding 1 tablespoon of milk (dairy or plant-based) can make the cake slightly moister. It's optional; the cake works perfectly without it.
