Kitchen Tools You’ll Need
- Microwave-safe mug
- Small bowl
- Spoon or whisk
Ingredients
- 1 tablespoon unsalted butter, melted (adds richness)
- 1 tablespoon granulated sugar (provides sweetness)
- 1/2 teaspoon cinnamon (adds warmth and flavor)
- 1/4 teaspoon vanilla extract (enhances overall flavor)
- 1 large egg yolk (or 1 tablespoon of applesauce for a vegan option) (binds ingredients)
- 3 tablespoons all-purpose flour (offers structure)
- 1/8 teaspoon baking soda (helps with leavening)
- 1 pinch salt (balances sweetness)

How to Make Easy Snickerdoodle Mug Cookie
Step 1. Begin by melting the unsalted butter in a microwave-safe mug. This should take about 10 to 15 seconds. You just want the butter to be liquid, which will help blend the ingredients together smoothly.
Step 2. Add granulated sugar and ground cinnamon to the melted butter in the mug, stirring them together until fully combined. You’ll notice the mixture becomes slightly grainy due to the sugar, and the cinnamon will provide a warm aroma.
Step 3. Pour in the vanilla extract and mix it into the butter-sugar mixture until it’s well incorporated. This will add a lovely depth of flavor, enhancing the sweetness of the cookie.
Step 4. Carefully add the egg yolk (or applesauce for a vegan alternative) to the mixture in the mug. Mix it in thoroughly to incorporate the wet and dry ingredients, ensuring the texture is consistent.
Step 5. Gradually add the all-purpose flour along with the baking soda and a pinch of salt. Stir until the mixture forms a thick batter. You want the flour to be fully combined, with no visible dry bits left, so the cookie firms up nicely during cooking.
Step 6. Finally, give the mixture a good stir to ensure everything is well blended. At this point, the batter should be smooth and thick with a slightly sticky consistency. This ensures a good texture once baked.
Step 7. Microwave the mug for about 30 to 40 seconds. Watch closely as it cooks; the batter should rise slightly and become firm but still soft in the center. You’ll know it’s done when the top looks set and is slightly puffed.

Pro Tips for Best Results
- Be careful not to overcook the mug cookie, as it can become dry. Start with the shortest time recommended and add seconds if needed.
- Use a microwave-safe mug to prevent any kitchen accidents while cooking.
- If you’re using applesauce instead of an egg yolk, make sure it’s unsweetened for the best flavor balance.
- Allow the cookie to cool slightly before eating to avoid burning your mouth.
- Experiment with different toppings, such as a sprinkle of additional cinnamon-sugar or a dollop of whipped cream.
Common Mistakes to Avoid
- Overmixing the batter: This can lead to a dense texture. Mix just until combined for a lighter cookie.
- Not watching the cooking time: Overcooking can dry out the cookie. Start with less time and add if needed.
- Using the wrong mug: A non-microwave-safe mug may crack. Always ensure your mug is labeled microwave-safe.
- Incorrect measurements: Using too much flour can make the cookie tough. Measure carefully, especially with flour.
- Using cold ingredients: Cold butter or eggs might not blend well, affecting texture. Room temperature ingredients are best.
- Skipping the salt: It enhances flavor. Omitting it might leave the cookie tasting flat.
Variations & Substitutions
Feel free to add chocolate chips or nuts to the batter for extra texture and flavor. You could also experiment with different spices, like nutmeg or ginger, for a unique twist.
Storage & Reheating
For room temperature storage, enjoy the mug cookie fresh. If you have leftovers, store them in an airtight container at room temperature for up to a day. For refrigerator storage, place it in the fridge for up to three days. The best way to reheat is to pop it in the microwave for about 10 seconds to revive its warmth and softness.
