I love a delicious fresh peach cake, but in the heat of the summer, the thought of turning on the oven stops me in my tracks. So, instead, I’ve started to make this peach mug cake instead! It’s the perfect serving for one person and it’s ready in minutes, with no oven required!
Why Make a Peach Mug Cake
A peach mug cake is a single-serving easy dessert that you can quickly prepare and cook in a microwave using a mug or other microwave-safe cup.
It’s a convenient and delicious way to enjoy the flavors of a fresh peach cake without the need for turning on your conventional oven, or making an entire large cake if you’re only serving a smaller group.
This personal-sized cake is one of my favorite ways to use juicy peaches during the hot summer peach season when I’m not cooking for a crowd!
Key Features of a Peach Mug Cake
- Quick and Easy Preparation: You can make a peach mug cake in just a few minutes, making it perfect for a quick dessert or snack!
- Simple Ingredients: The recipe uses pantry staples such as flour, sugar, baking powder, milk, and butter, along with the addition of diced peaches. Fresh, canned, or even frozen peaches can be used (though I prefer fresh here)
- Minimal Cleanup: Since the cake is mixed and cooked in the same mug, there are very few dishes to wash afterward!
- Customizable: You can easily customize the recipe by adding spices like cinnamon or nutmeg, or by topping the cake with whipped cream, ice cream, or a drizzle of caramel sauce

Peach Mug Cake Ingredients
- ¼ cup all purpose flour
- 2 Tbsp brown sugar
- ⅛ tsp ground cinnamon
- ½ tsp baking powder
- ⅛ tsp salt
- 3 Tbsp milk (I use 2%)
- 1 Tbsp butter, melted
- ½ tsp vanilla extract
- ½ fresh peach, peeled, pitted, and diced
Ingredient Tips and Substitutions
- You can swap in gluten free flour or whole wheat flour (cooking times can vary slightly, and expect a slightly denser texture) for the all purpose flour. Alternatively, use about ⅓ cup of cake mix (yellow or butter) in place of the flour, sugar, and baking powder
- Instead of brown sugar, you can use granulated or honey. If you like really sweet cakes or your peaches are underripe, you can add up to 1 Tbsp extra
- Non-dairy milk (like almond milk) and vegan butter can be swapped in if preferred
- You can also use about ¼ cup of canned or frozen (defrosted) peaches. Canned do not require pre-cooking like the others
- While optional, you may want some extra fresh peach slices for topping, or ice cream or whipped cream with a sprinkle of cinnamon are good choices too
How to Make a Peach Mug Cake
- To a microwave-safe mug (preferably 10-ounces or larger) add the diced peaches, brown sugar, and cinnamon
- Place in the microwave and cook on high (full power) for 30-45 seconds, or until the peaches soften slightly (remove when they start to bubble)
- Remove the mug, then add the remaining ingredients and stir until just combined (do not overmix or your cake will be tough)
- Return to the microwave and cook on high for 45 seconds to 1 minute. Add additional time in 15-second increments as needed, until the center is just set. It may appear wet, but should not actually be wet to the touch
- Serve immediately, with a scoop of vanilla ice cream, whipped cream, or fresh peach slices if desired

Recipe FAQs
Can I Use Canned Peaches Instead Of Fresh Peaches?
Yes, you can use canned peaches. Make sure to drain them well before adding them to the batter.
Fresh peaches will provide the best flavor and texture, but canned peaches are a convenient alternative.
How Long Does It Take To Cook A Peach Mug Cake?
A peach mug cake typically takes about 1 ½ to 2 minutes to cook in the microwave, including about 30-45 seconds to cook the peaches.
Cooking times can vary depending on the wattage of your microwave, so start with the lowest end of cooking time, and then add additional time in small increments.
Can I Make This Mug Cake Gluten Free?
Yes, you can make a gluten free version by substituting the all purpose flour with a gluten free flour blend.
For best results, ensure the blend includes xanthan gum or a similar binder to maintain the cake’s structure.
Is It Possible To Make A Vegan Peach Mug Cake?
Absolutely! You can replace the milk with a non-dairy alternative like almond or soy milk, and use vegetable oil or melted coconut oil instead of butter.
Ensure all other ingredients are labeled as vegan-friendly, as often there are additives used during processing that make naturally vegan products no longer safe.
How Do I Know When The Mug Cake Is Done?
The mug cake is done when it has risen and is firm to the touch. You can also insert a toothpick into the center; if it comes out clean, the cake is ready.
Avoid overcooking as it can become dry.
What Is The Best Way To Serve A Peach Mug Cake?
The peach mug cake can be enjoyed warm directly from the mug.
For an extra treat, top it with a scoop of vanilla ice cream, whipped cream, or a drizzle of caramel sauce.
Can I Make Multiple Mug Cakes At Once?
Yes, you can prepare multiple mug cakes, but it’s best to cook them one at a time in the microwave to ensure even cooking.
You can mix the batter in separate mugs and microwave them individually.
Peach Mug Cake Recipe Pro Tips
- I made my mug cake in a 1000W microwave. Times will vary for other wattages and based on the size of your mugs, so adjust up and down as needed. I did both the peaches and the cake for 45 seconds each, and that was perfect for me!
- Check your cake frequently near the end of cooking, as overcooking can lead to a rubbery cake
- The peach flavor is not overly strong in this cake. If you want a more prominent flavor, consider adding a full peach, or use some peach juice or nectar in place of some of the milk
Storage and Reheating of Mug Cakes
- Mug cakes are truly best enjoyed fresh. However, you can store your peach mug cake for up to 24 hours in the refrigerator
- To reheat a mug cake, microwave for 20-30 seconds to warm through (keep it to a minimum to reduce how much it dries the cake out)
- If you want to save time, you can make the peach mixture in advance and store that up to a day ahead. Measure out all dry ingredients and store separately as well. Then, you can just combine, add wet ingredients, and cook for a time-saving option!

I was originally looking for a sourdough peach mug cake, but I found yours and tweaked it to more closely resemble what I was craving! I added SD discard in addition to the flour, less butter, no brown sugar, but instead replaced it with allulose, and kefir in place of the milk. It was so good that I am writing the recipe down so I don’t forget my tweaks!
Thank you for your inspiration!
I’m so glad to hear that this base recipe worked so well! I love hearing creative applications like this, and I’m so glad you mentioned your modifications since I’m sure it can help others in the future too. It’s such a quick and easy summer dessert option, and I’m sure the peach flavor pairs so well with sourdough discard too, what a great use for it!
I would use 1T brown sugar next time instead of 2T. It was very good! Just don’t want it overly sweet.
Yeah a lot definitely depends on your personal taste and how sweet your peaches are. Glad you enjoyed it and already have some recipe adjustments in mind for next time!
