Exact Ingredients List
The Snickerdoodle mug cake needs just a few simple ingredients. You’ll mix dry and wet ingredients for the cake, then make a quick cinnamon-sugar topping.
For The Mug Cake
For the cake part, you’ll need:
- 6 tablespoons all-purpose flour
- 1/4 teaspoon baking powder
- A pinch of salt
- 1 1/2 tablespoons granulated sugar
- 1/4 teaspoon ground cinnamon
- 1/4 cup milk, room temperature
- 2 tablespoons unsalted butter, melted and cooled a bit
- 1/2 teaspoon pure vanilla extract
Make sure your milk is at room temp and your melted butter has cooled slightly. This helps everything mix better.
For The Cinnamon Sugar Topping
The yummy topping is super easy. You just need:
- 1 tablespoon granulated sugar
- 1/4 teaspoon ground cinnamon
Mix these two ingredients in a small bowl. You’ll sprinkle this between layers of cake batter and on top. It gives your mug cake that classic snickerdoodle taste and a nice crunchy top.

Instructions
Mix the dry ingredients in a small bowl. Add 6 tablespoons flour, 1/4 teaspoon baking powder, a pinch of salt, 1 1/2 tablespoons sugar, and 1/4 teaspoon cinnamon. Stir until well combined.
Pour in 1/4 cup milk, 2 tablespoons melted butter, and 1/2 teaspoon vanilla. Mix gently until the batter is smooth. Don’t overmix!
Grab a big microwave-safe mug (14 ounces or larger). Spoon some batter into the bottom. Make the topping by mixing 1 tablespoon sugar with 1/4 teaspoon cinnamon.
Sprinkle some topping over the batter. Keep layering batter and topping until you use it all up. End with topping on top for a yummy crust.
Microwave on high for 1 minute. Check if it’s done – it should be puffy and set. If needed, cook for 30 more seconds. Be careful not to overcook!
Let your mug cake cool for 2-3 minutes. It’ll be super hot! Then dig in and enjoy your warm, cinnamon-y treat. Yum!

Possible Substitutes List
You can swap out some ingredients in this Snickerdoodle mug cake recipe if needed. Here are some easy substitutes:
- All-purpose flour: Use whole wheat flour or gluten-free flour mix
- Milk: Try almond milk, soy milk, or coconut milk
- Butter: Replace with coconut oil or vegetable oil
- Vanilla extract: Use almond extract for a nutty twist
For the sugar, you have options too:
- White sugar: Brown sugar or coconut sugar work well

Don’t have baking powder? Mix 1/8 teaspoon baking soda with 1/4 teaspoon vinegar or lemon juice.
Remember, these swaps might change the taste and texture a bit. But they’ll still give you a yummy mug cake in no time!
How To Make It Diabetes-Friendly
To make this snickerdoodle mug cake more diabetes-friendly, you can try a few simple swaps. Replace the all-purpose flour with almond flour or coconut flour. These low-carb options will help keep blood sugar levels steady.
Instead of regular sugar, use a sugar substitute like stevia or erythritol. These sweeteners won’t spike your blood glucose. For the milk, choose unsweetened almond milk or another low-carb alternative.
Here’s a quick list of diabetes-friendly substitutions:
- Almond flour instead of all-purpose flour
- Stevia or erythritol instead of sugar
- Unsweetened almond milk instead of regular milk
When making the topping, mix cinnamon with a sprinkle of your chosen sugar substitute. This gives you the classic snickerdoodle taste without the extra carbs.
Remember to adjust cooking times slightly. Low-carb flours may need an extra 15-30 seconds in the microwave. Keep an eye on your mug cake to avoid overcooking.
By making these changes, you can enjoy a tasty treat that’s kinder to your blood sugar levels. Always check with your doctor about including sweets in your diet, even when they’re made with diabetic-friendly ingredients.
Tips, Tricks & Storing
Use a big mug for this cake. Pick one that holds at least 14 ounces. This stops the batter from spilling over while cooking.
Don’t overmix the batter. Stir just until you can’t see any dry spots. Too much mixing can make your cake tough.
Watch the cake closely as it cooks. Start checking at 1 minute. It’s done when the top looks dry and set. The cooking time may change based on your microwave’s power.
Try adding extras to your cake. A spoonful of cream cheese or a dollop of peanut butter in the middle can be yummy.
Make the batter ahead of time if you want. Keep it in the fridge for up to a day. Just give it a quick stir before cooking.
Sadly, this cake is best eaten right away. It can get dry if you try to store it. If you must save it, wrap it tight and eat within a day.
For a fun twist, top your warm cake with a scoop of vanilla ice cream. The mix of warm and cold is super tasty!
