Chocolate Strawberry Mug Cake Recipe
This is the core recipe you can trust. After you make it once, you can explore the variations later in the post.
Ingredients (1 Mug Cake)
You will need 4 tablespoons of all-purpose flour, 2 tablespoons of unsweetened cocoa powder, 2 to 3 tablespoons of sugar depending on how sweet you like it, 1/4 teaspoon baking powder, and a pinch of salt. For the wet ingredients, you will need 4 tablespoons milk, 2 tablespoons neutral oil or 2 tablespoons melted butter, and 1/4 teaspoon vanilla extract. For the mix-ins, you will need 3 to 4 tablespoons chopped strawberries and 1 to 2 tablespoons chocolate chips. If you want extra strawberry flavor, you can add 1 teaspoon of strawberry jam.
What You’ll Need (Tools + One Smart Tip)
You do not need much, but the few things you choose do matter. Mug cakes cook fast, and that means small details can make a big difference in texture.
Use a microwave-safe mug that holds at least 12 ounces, and 16 ounces is even better. This gives the batter room to rise without spilling over the top. A wider mug also helps the cake cook more evenly. If your mug is very tall and narrow, the center can stay undercooked while the edges get tough.
You will also want a spoon or small whisk for mixing, and a measuring spoon set. If you have measuring cups, great. If not, you can still do this with tablespoons, as long as you measure with care.
Best Mug Size and Why It Matters
A mug cake rises as it cooks. If the mug is too small, it can bubble up and overflow. That makes a mess and also throws off the cooking time. A larger mug gives you a cleaner cook, better texture, and less stress. Aim to fill the mug no more than halfway with batter. That simple rule prevents most mug cake disasters.
Microwave Power: The Hidden Key
Microwaves are not all the same. Some are stronger than others. A stronger microwave cooks faster, and a weaker one needs more time. That is why mug cake timing is always a range. The goal is not to blast it for one long time. The goal is to cook it in a way that keeps it soft.
A smart method is to start with a base cook time, then finish with short bursts. This helps you avoid overcooking, which is the biggest reason mug cakes turn dry or rubbery.
Recipe Method (Step by Step and in Complete Detail)
This section is written so you can follow it in your kitchen without confusion. Read it once, then cook along with it. Mug cakes move fast, so it helps to have the steps clear in your mind before you start.
Step 1: Choose the Right Mug and Prep It
Start with a microwave-safe mug that holds at least 12 ounces. If you are not sure, choose the biggest mug you have. Lightly grease the inside with a tiny bit of oil or butter. This is optional, but it makes the cake easier to eat from the sides and helps prevent sticking if you plan to tip it out onto a plate. Set the mug on a microwave-safe plate. That plate is your safety net in case the cake rises high and drips a little.
Step 2: Mix the Dry Ingredients Thoroughly
Add the flour, cocoa powder, sugar, baking powder, and salt directly into the mug. Use your spoon to mix slowly and thoroughly. Scrape the bottom and the corners. Cocoa powder loves to hide in dry pockets, and flour can cling to the edges. Keep mixing until the color looks even, with no pale flour streaks and no cocoa lumps. This dry mix step is more important than it sounds because an uneven mix can give you bitter cocoa bites in one spot and bland flour bites in another.
Step 3: Add the Wet Ingredients and Stir Until Smooth
Pour in the milk, oil or melted butter, and vanilla. Stir slowly at first so the dry ingredients do not puff up and fly out. Then stir with purpose. You want a smooth batter that looks glossy and thick, like a loose brownie batter. Keep scraping the bottom as you mix because flour can settle there and turn into a dry clump that never blends. If your batter looks too thick to stir, add 1 more tablespoon of milk. Different flours and cocoa powders can absorb liquid differently, and a small splash is sometimes needed.
Try not to overmix once the batter is smooth. Overmixing can make the cake a little tough. The goal is smooth and combined, not heavily beaten.
Step 4: Add Strawberries and Chocolate Without Crushing Them
Now add the chopped strawberries and chocolate chips. If you are using strawberry jam, add it now too. Fold them in gently. Folding means you stir just enough to spread them through the batter, without mashing the strawberries into a wet puree. Small strawberry pieces are ideal because they soften during cooking and give you sweet pockets without flooding the batter with juice. Save a few strawberry pieces and a few chocolate chips to sprinkle on top. This makes the mug cake look better and gives you a melty, fruity top layer.
Step 5: Set Your Microwave Timing the Smart Way
Place the mug on the plate into the microwave. Cook on high power for 60 seconds first. Then stop and check. You are looking for a cake that has risen and looks set around the edges but still slightly soft in the center. If the surface still looks wet and raw, cook for 15 seconds more. Check again. Keep going in 10 to 15 second bursts until it looks mostly set.
For many microwaves, the total time is about 70 to 95 seconds. Strong microwaves may finish closer to 60 to 75 seconds. Weaker microwaves may take closer to 90 to 110 seconds. The exact number is less important than the look and feel. The cake should not look like liquid batter, but it also should not look dried out.
A helpful test is the gentle touch test. Carefully touch the top with a fingertip. If it feels sticky and wet, it needs more time. If it feels springy and set, it is done. If it feels firm and dry, it likely went a little too long. That is why short bursts work so well.
Step 6: Let It Rest Before You Dig In
When the microwave stops, let the mug cake rest for at least 1 minute. This is not just waiting for it to cool. The cake continues to cook slightly from the heat trapped inside the mug. That rest time helps the center finish setting without extra microwave time, and it keeps the texture softer.
After resting, add your toppings and enjoy it warm. Mug cakes taste best fresh, right out of the microwave, when the chocolate is still melty and the strawberries are warm and jammy.
Flavor Variations You’ll Actually Want to Make
Once you master the base recipe, these variations keep things exciting without making the method complicated.
Chocolate-Covered Strawberry Style
To get that chocolate-dipped strawberry feel, add a few extra chocolate chips on top before microwaving. When the cake finishes, the top chocolate will be glossy and melted. Add a few fresh strawberry slices after cooking for a bright, fresh finish.
Fudgy Center Version
For a softer, richer center, reduce the cooking time. Start with 60 seconds, then add only 10-second bursts until the edges are set and the center is still a little soft. You can also press a small square of chocolate into the middle of the batter before cooking. When you spoon into it, you get a warm chocolate pocket.
Eggless and Vegan-Friendly Option
This base recipe already works without eggs, which is one reason it is so convenient. To make it vegan, use a non-dairy milk and choose dairy-free chocolate chips. Use oil instead of butter. The texture stays tender and the flavor still feels rich.
Strawberries and Cream Style
After the cake rests, add a spoon of whipped cream or a spoon of thick yogurt. The cool cream against warm chocolate is a simple pleasure. You can also add a small swirl of strawberry jam on top for extra fruit flavor.
Serving Ideas and Toppings
A mug cake is delicious on its own, but toppings turn it into a real dessert moment. Keep it simple and choose one or two toppings so the flavors stay balanced.
A classic topping is whipped cream. It melts slightly into the warm cake and tastes like strawberries and cream. Ice cream is another favorite, especially vanilla or strawberry. If you want something lighter, dust a little powdered sugar over the top and add a few fresh strawberry slices. For more chocolate, drizzle melted chocolate or sprinkle extra chips right after cooking so they soften from the heat.
If you are making this for a special night, serve the mug cake on a small plate with a few fresh strawberries on the side. It looks thoughtful, but it takes almost no extra work.
Storage and Make-Ahead Tips
Mug cakes are best eaten right away. They are designed for a fresh texture and warm flavor. Still, you can prepare smartly so you can make them even faster later.
If you must save a cooked mug cake, cover it and store it at room temperature for a short time, or in the fridge for up to a day. Reheat gently in the microwave for 10 to 15 seconds. Do not reheat for a long time, or it will turn dry.
A better idea is make-ahead dry mix. Combine the flour, cocoa powder, sugar, baking powder, and salt in a small jar or bag. When you want dessert, pour the mix into a mug, add the wet ingredients, then stir in strawberries and chocolate. This makes weeknight desserts feel effortless.
Troubleshooting: Fix Common Mug Cake Problems
If your first mug cake is not perfect, do not worry. Mug cakes are fast, so it is easy to adjust and try again. Here are the most common issues and how to fix them.
My Mug Cake Overflowed
Overflow usually means the mug was too small or the cook time was too long. Use a larger mug next time and fill it no more than halfway with batter. Also, cook in shorter bursts, especially near the end.
It’s Dry or Rubbery
This is almost always overcooking. Reduce the total time and rely on the rest period. Add a tablespoon of chocolate chips for extra moisture and richness. You can also switch to oil if you used butter, since oil tends to keep mug cakes softer.
Raw Middle, Cooked Edges
This often happens when the microwave is very strong or the mug is narrow and tall. Use a wider mug if possible. Try cooking on a slightly lower power setting and increase the time. Short bursts at the end help a lot.
The Chocolate Flavor Feels Weak
Use unsweetened cocoa powder with a strong chocolate taste, and do not skip the pinch of salt. Add chocolate chips or chopped chocolate to boost richness. You can also replace 1 tablespoon of milk with 1 tablespoon of cooled coffee if you like the flavor. Coffee makes chocolate taste deeper, and it does not make the cake taste like coffee when used in a small amount.
FAQs
Mug cakes are simple, but small questions matter because the cooking time is short and the portion is small. These answers will help you feel confident.
How long do you microwave a chocolate strawberry mug cake?
Most mug cakes like this take about 70 to 95 seconds total, but it depends on your microwave. Start with 60 seconds, then finish with 10 to 15 second bursts until the edges are set and the center is only slightly soft. Always let it rest for one minute before eating because it keeps cooking a little from the heat.
What microwave strength is this recipe written for?
This method works for most home microwaves because it uses a timing range and short bursts. If your microwave is very strong, it may finish sooner. If it is weaker, it may need more time. The best guide is how the cake looks, not a single exact number.
Can I use frozen strawberries?
Yes, but thaw them first and pat them dry. Frozen fruit releases water, and that extra water can make the batter thin and the cake gummy. Small chopped pieces work best.
Can I make it without eggs?
Yes. This recipe does not use eggs, and it still rises nicely because of baking powder. The texture is tender and rich, especially with chocolate chips mixed in.
Can I bake this in the oven instead?
You can, but mug cakes are designed for microwave speed. If you want to use the oven, pour the batter into a small oven-safe ramekin and bake at 350°F (175°C) until set, usually around 12 to 16 minutes. The texture will be more like a traditional cake, but it will not be as fast.
What’s the best cocoa powder to use?
Use unsweetened cocoa powder. If you have cocoa that tastes richer and darker, it will make the mug cake taste better. If your cocoa tastes mild, add chocolate chips to boost the chocolate flavor.
Conclusion: One Mug, Big Reward
Chocolate strawberry mug cakes are the kind of dessert that makes a regular day feel better. They are fast, warm, and full of comfort, and they still feel special because of that chocolate-and-berry combo. Try it once, then play with the variations until you find your favorite version.
