Ingredients for 2 ingredient cake with cake mix and pie filling

Two ingredients, one mug, and 90 seconds to dessert heaven—no baking skills needed.

The cake mix is the star here—any flavor works, but vanilla or chocolate are foolproof. Check the box for water requirements—some mixes need 1/2 cup, others 3/4. The pie filling can be any flavor you like, but apple or cherry pair best with vanilla cake mix. I always grab the canned filling from Trader Joe's or Walmart—they're budget-friendly and taste fresh. For the mug, any microwave-safe ceramic or glass mug works, but a 12-16 oz size gives you the perfect single-serving portion. If you're feeling fancy, use a ramekin dish for a slightly more elegant presentation.

No egg? No problem—this recipe works fine without it, but adding one makes the cake slightly denser. Milk instead of water adds richness, but water keeps it light. Running short on pie filling? Jam or jelly works in a pinch, though it won't have the same gooey texture. The oil is optional but helps prevent sticking—just a light coat on the inside of the mug. For extra indulgence, stir in 1 tbsp chocolate chips or crushed cookies before microwaving. If you're making this for a crowd, double the ingredients and use a larger microwave-safe bowl for a mini cake.

This cake is best served immediately, but if you must wait, cover loosely with plastic wrap and microwave for 10-15 seconds to reheat. The mug can go straight in the microwave—no preheating needed. For a make-ahead option, mix the cake batter and pie filling in the mug, cover tightly, and refrigerate for up to 24 hours. When ready to bake, microwave as directed. Leftovers? There are none—this disappears faster than you can say 'dessert.' Store any uneaten batter in the fridge for up to 2 days, but honestly, you won't have any left.

Step-by-step instructions for microwave mug cake

Here's how to create a perfectly moist, filling-filled cake in under two minutes.

Start by greasing the inside of the microwave-safe mug with 1 tablespoon vegetable oil. Use a paper towel to rub the oil evenly around the entire interior—this prevents sticking and ensures easy removal. I like to use a clean paper towel to wipe away any excess oil that drips down the sides, keeping the cake clean and professional-looking.

Next, pour ½ cup water into the mug. This liquid is crucial for activating the cake mix and creating a tender crumb. If you're using milk instead of water for extra richness, now's the time to add it. The water (or milk) should cover the bottom of the mug completely—this helps distribute the oil evenly and creates a proper batter consistency.

Add 1 box boxed cake mix to the mug and stir vigorously with a fork or wooden spoon for 30 seconds. You want to break up all the dry lumps completely—this ensures even baking and prevents dry spots in your cake. The batter should be thick but pourable, like heavy pancake batter. If it's too thick, add 1 teaspoon more water and stir again.

Now comes the optional but recommended step: crack 1 whole large egg directly into the mug and mix it in. The egg acts as a binder, giving your cake extra structure and preventing it from crumbling. If you're skipping the egg (like I sometimes do for a lighter texture), make sure to stir the batter extra well to compensate for the missing binding agent. The batter should now be smooth with no visible dry spots.

Spoon ½ cup canned pie filling into the center of the mug. I like to make a small well in the middle of the batter to contain the filling—this creates a clean, professional-looking layer when you microwave it. Press down gently on the pie filling with a spoon to compact it slightly, which helps it blend better with the cake during baking. The filling should be visible through the batter, creating that beautiful swirled effect.

For best results, use a pie filling that's at room temperature. If yours is refrigerated, let it sit at room temperature for 5 minutes before using. Cold filling can cause uneven baking or create a watery layer in your cake. The filling should be thick enough to hold its shape when spooned but still spreadable enough to mix partially with the cake during cooking.

Place the mug in the microwave and cook on high power for 60 seconds. This initial cooking time ensures the outer layer of cake sets up while keeping the center moist. After the first minute, carefully remove the mug and give the cake a quick stir with a fork—this helps blend the pie filling into the cake for that signature swirled effect. The cake should be mostly set but still slightly jiggly in the center.

Return the mug to the microwave and cook for another 30 seconds. You're looking for a cake that's fully set but still warm and moist in the center. A toothpick inserted into the center should come out with a few moist crumbs but no wet batter. If the cake looks underdone, cook for 10-second intervals until fully set. Overcooking will make the cake dry, so it's better to slightly undercook it and let it finish setting while you prepare your optional milk topping.

Let the cake cool in the mug for 1 minute—this allows it to set completely and makes it easier to remove. While it cools, drizzle 1 tablespoon whole milk over the top for extra richness and a beautiful presentation. The milk will create a glossy finish and enhance the cake's flavor. For a more decadent touch, you can also sprinkle a pinch of powdered sugar or a dusting of cinnamon on top.

Run a butter knife around the edge of the mug to loosen the cake, then invert it onto a plate. The cake should release cleanly if you've greased the mug properly. Serve immediately while warm, cutting into wedges with a sharp knife. The contrast of warm cake with the cool pie filling creates the perfect texture combination. This cake is best enjoyed fresh from the microwave—it loses its moisture and texture as it cools completely.

Creative variations of these flavors

Flavor Combos

Pair vanilla cake mix with apple or cherry pie filling for a classic, comforting combo. The mild sweetness of vanilla lets the fruity flavors shine through beautifully. For chocolate lovers, use chocolate cake mix with blueberry or raspberry pie filling—the tartness cuts through the richness perfectly. 🍎

Spiced Variations

Add ½ teaspoon cinnamon or ¼ teaspoon pumpkin pie spice to your batter for warmth. Stir it in after mixing the cake mix and before adding the pie filling. For a boozy twist, drizzle 1 teaspoon bourbon or vanilla extract over the top after microwaving. The alcohol enhances the fruity notes while adding depth.

Protein Twist

Boost this dessert with 1 scoop vanilla protein powder mixed into the cake batter. Use ½ cup water instead of milk to keep it light, then top with ½ cup Greek yogurt instead of milk. This turns your treat into a post-workout recovery dessert with 15 grams of protein per serving. The yogurt adds creaminess without overpowering the pie filling.

Seasonal Swaps

In fall, use pumpkin pie filling with vanilla cake mix and sprinkle with pecans before microwaving. For spring, try strawberry pie filling with lemon cake mix—add 1 teaspoon lemon zest to the batter for brightness. Winter calls for cranberry pie filling with spiced cake mix, while summer works well with mango or peach pie filling for tropical vibes.

Dairy-Free Options

Replace milk with unsweetened almond milk or oat milk for a dairy-free version. Use ½ cup coconut yogurt instead of milk for topping, and ensure your cake mix is labeled dairy-free. For extra richness, stir 1 tablespoon coconut oil into the batter instead of vegetable oil. The coconut pairs beautifully with tropical pie fillings like pineapple or mango.

Make-Ahead Mix-Ins

Prep ahead by mixing the cake batter and pie filling in the mug, then refrigerate for up to 24 hours. Before microwaving, add ¼ cup mini chocolate chips or crushed graham crackers for texture. For a breakfast twist, stir in 1 tablespoon peanut butter with the pie filling—it adds protein and nutty contrast to sweet flavors. Store mix-ins in airtight containers in the fridge for up to 1 week.
