Three different gluten free mug cakes.


Gluten free Mug Cakes are fast, easy and delicious. They’re cooked in the microwave and are ideal for any occasion when you need a quick dessert. Whether it’s a special day at school, visiting friends or those large family gatherings where no food choices feel safe; mug cakes might be the answer.

This recipe uses one egg and serves one or two people. The cooked cake will fill a 16-ounce mug or the batter can be divided into two smaller mugs and baked together at the same time.

A Mug Cake Party

You’ll have to make a few mug cakes to find your favourite mugs and the serving size that’s right for you. Have a Mug Cake Party and invite a friend.

In a 90-minute virtual cooking class we figured out the right microwave settings in every kitchen, tried different mug sizes and shapes, plus we made three different mug cakes. Everyone tasted all three cakes, determined the right serving size and had fun with different garnishes.

You can organize a simple Mug Cake Party like this at home. Now that we all know several ways to connect virtually you could even host a party with far away family or friends. Send them the link to this post and they’ll have all the recipes.

Travel Like A Celiac

Celiacs know how to transport food and these mug cakes are ideal for travel. The cake can be mixed up at home and taken in a 2-cup Mason jar. For over night trips or if you don’t want to fully mix the batter in advance take the dry ingredients in a large jar for baking and mix the wet ingredients in a smaller jar. It really is a piece of cake!

The key is getting the right microwave setting wherever you go so you can cook your cake perfectly every time. Here’s a general guide for determining the setting.

  • Fill a 1-cup liquid measuring cup with tap water. Microwave as follows and watch to see when it reaches a boil. That should be about the time it takes to cook your mug cake. If it boils before the time then decrease the length of time you’ll cook your cake. Each time you do a test be sure to start with water right out of the tap (not hot water).
  • As a general guide if your microwave is 1000 watts or less, cook on full power for 2-3 minutes.
  • If your microwave is > 1000 watts cook on power setting 7 or 8 for about 2 minutes.

5 Fun Ideas For Over-The-Top Mug Cakes

In a recent Kids Cooking Class I asked the kids what over-the-top meant to them. It can be hard being a gluten free kid living in a gluten-filled world. To make up for the inevitable disappointments when there are no safe food choices for you, remember your over-the-top mug cakes.

So I asked them to think about creating an over-the-top dessert! Here are five fun ideas to do just that with your gluten free mug cake.

  1. Chocolate Mug Cake – Top with ice cream, caramel sauce, fresh berries and an Oreo cookie to finish it off. (I know some kid is going to want pretzel sticks stuck in that scoop of ice cream.)
  2. Double Chocolate Mug Cake – Top with a generous amount of whipped cream, more mini chocolate chips and sauce (chocolate, raspberry or caramel).
  3. Triple Chocolate Mug Cake – Before baking in the microwave lay a piece of chocolate (or a caramel filled piece of chocolate) on top of the cake batter. Bake and cool as usual. Top with chocolate ice cream, drizzle with shaved chocolate or chocolate sprinkles.
  4. Love Cake – Pile on loads of whipped cream, drizzle with raspberry sauce and decorate with heart shaped sprinkles plus a heart shaped sugar cookie to top it off.
  5. Funfetti Mug Cake Sundae – Top with your favourite ice cream, whipped cream, extra confetti sprinkles and a maraschino cherry on top.

Printables – 3 Recipes for Gluten Free Mug Cakes

I love to print new recipes and post them inside any cupboard door to inspire me to try something new.

It’s All About The Flour

I often write about gluten free flour and after ten years of cooking gluten free I’m still learning about flour. I talk about the New Basics for Gluten Free Bakers, the essentials for anyone new to quickly learn to bake successfully. Once your recipes work you can improve from there.

If you’re interested take a look at my post, 11 Gluten Free Flour Recipes. I don’t use 11 different flour blends but readers tell me this table helps them with flour substitutions and seeing ways they might combine different flours and starches.

I also have a Downloadable Gluten Free Flour Guide covering the differences of some of the flours and starches, what percentages work best in a flour blend and how best to use them.

Gluten Free Mug Cakes: Funfetti, Chocolate and Lemon-Blueberry

Gluten free mug cakes are fast, easy and delicious. They cook in the microwave, can be lavishly garnished and are perfect for any occasion.
Author: Cinde Little
Course: Dessert
Keyword: gluten free mug cakes
Servings: 2


  • ¼ cup gluten free flour (I use my EGFG flour blend*)
  • 2 Tbsp sugar
  • ½ baking powder
  • 1 egg
  • 2 Tbsp vegetable oil
  • 1 Tbsp milk (or dairy free milk)
  • ¼ tsp vanilla extract
  • 2 tsp confetti sprinkles
  • GARNISH - whipped cream and more sprinkles
  •  *EGFG flour blend: 300g sweet rice flour, 300g potato starch, 200g sorghum flour, 200g millet flour (makes ~8 cups)


  • In a separate bowl mix dry ingredients together. Set aside.
  • In a 1-cup measuring cup mix wet ingredients until thoroughly combined.
  • Add wet ingredients to dry. Stir until no flour is visible.
  • Transfer to greased mug. Bake in microwave for 1½ - 2 minutes**. Time will vary based on microwave wattage. (see notes)
  • Let cake cool for 2 minutes. Garnish as desired and serve.


**Microwave settings - Find the wattage of your microwave on a label around the door. Adjust cooking time and power level to determine the best settings to bake a mug cake. I bake mine in a 1200 watt microwave at power level 7 for 2 minutes. (It is possible to burn a cake in the microwave. If your microwave is 1200 watts or higher use a setting less than full power.) 
Batter can be divided into 2 smaller mugs or Mason jars and baked at the same time.
Cooked cake can be transferred to 2 mugs or plates if serving 2.
Mug Cake Variations:
Chocolate Mug Cake - Add 1 Tbsp cocoa powder to the dry mix. Replace 2 tsp sprinkles with 2 tsp mini chocolate chips.
Lemon-Blueberry Mug Cake - Replace 1 Tbsp milk with 1 Tbsp lemon juice. Replace 2 tsp sprinkles with 2 tsp small blueberries.
