This snickerdoodle mug cake is quick, soft, and filled with the cozy cinnamon sugar flavor of a classic snickerdoodle cookie. The mug is coated with buttery cinnamon sugar before cooking, and another sweet layer is tucked into the center of the vanilla cake for a warm, simple dessert made in minutes.
Snickerdoodles are loved for their simple, comforting combination of cinnamon and sugar. This easy snickerdoodle mug cake brings those same familiar flavors into a single-serving dessert you can make in less than 10 minutes. It is perfect when you want something sweet but do not want to bake a full batch of cookies or a whole cake.
The cake itself is a tender vanilla mug cake with a light, fluffy texture. What makes it special is the way the mug is prepared before the batter goes in. Melted butter is swirled around the inside of the mug, then cinnamon sugar is sprinkled over the butter so it clings to the bottom and sides. As the cake cooks, that coating gives every bite a sweet snickerdoodle-style finish. A second layer of cinnamon sugar is added between the batter, creating a warm, flavorful center.
This microwave mug cake is also a great recipe for beginners because it uses basic pantry ingredients and requires only a few minutes of prep. Measure carefully, mix gently, and use a large microwave-safe mug to help the cake cook evenly without overflowing.
Recipe ingredients
Ingredient notes
- Butter: Unsalted butter is used in this snickerdoodle mug cake. If you only have salted butter, leave out the pinch of salt in the cake batter.
- Milk: Whole milk gives the cake a richer texture, but skim milk, 2% milk, or non-dairy milk can also be used.
Step by step photos
1. In a small bowl, stir together the dry ingredients until evenly combined, then set the bowl aside.
2. Melt the butter in the microwave using the same mug you will cook the cake in. Once melted, carefully swirl the butter around the bottom and halfway up the sides of the mug. This helps the cinnamon sugar coating stick.
3. Pour the melted butter, milk, and vanilla into the dry ingredients. Mix just until the batter is smooth and no dry spots remain. Avoid overmixing, as this can make the mug cake dense instead of soft and tender.
4. In a separate small bowl, combine the remaining granulated sugar with the cinnamon. This mixture will be used to coat the mug, fill the center, and top the cake.
5. Sprinkle about one third of the cinnamon sugar into the buttered mug. Turn the mug as you sprinkle so the mixture coats the bottom and sides where the butter was swirled.
6. Add half of the cake batter to the mug. Sprinkle another third of the cinnamon sugar evenly over the batter, then add the remaining batter. Finish with the rest of the cinnamon sugar on top.
7. Microwave the mug cake until it is cooked through and no wet batter remains on top. You can enjoy it straight from the mug or turn it out onto a plate. Add a little extra cinnamon on top if desired.
Tips and tricks
- If your baking powder has small clumps, break them apart with your fingers, a fork, or a small whisk before adding it to the dry ingredients. Clumps are difficult to mix into the batter and can taste bitter in the finished cake.
- If the cake does not release easily from the mug, run a butter knife around the edges before turning it out onto a plate.
- Because this is a small-batch microwave cake, accurate measuring matters. A little too much flour or too little liquid can change the texture.
Recipe FAQs
Use a microwave-safe mug that holds at least 12 ounces. A larger mug gives the batter room to rise as it cooks. If you want extra protection, place the mug on a microwave-safe plate to catch any possible drips.
After microwaving for 90 seconds, check the top of the cake. It should look set and feel springy, with no wet batter remaining. You can also look along the sides for any uncooked pockets, but keep in mind that the cinnamon sugar coating may make the outside look moist.
If the cake needs more time, microwave it in 10-second increments and check again. Microwave ovens vary, so the exact cooking time may need a small adjustment.
Serve the cake warm, either directly from the mug or unmolded onto a plate. A light sprinkle of cinnamon makes a simple garnish. Whipped cream or vanilla ice cream can also be added if you want a richer dessert.

- Yield: 1 mug cake
- Category: Dessert
- Method: Microwave
- Cuisine: American
Ingredients
- 1 ½ tablespoons unsalted butter
- 3 tablespoons granulated sugar, divided
- 5 tablespoons all-purpose flour
- ½ teaspoon baking powder
- Pinch of salt
- ¼ cup milk
- ½ teaspoon vanilla extract
- ¼ teaspoon cinnamon, plus extra for garnish if desired
Instructions
1. In a small bowl, combine the flour, baking powder, salt, and 2 tablespoons of the granulated sugar. Stir well and set aside.
2. Place the butter in a large microwave-safe mug. Cover loosely with a folded paper towel to catch any spatter, then microwave on high for about 30 seconds, or until melted. Carefully swirl the melted butter around the bottom and halfway up the sides of the mug.
3. Pour the melted butter into the dry ingredients, then add the milk and vanilla extract. Mix with a fork or small whisk just until the batter is smooth and no lumps remain. Do not overmix.
4. In another small bowl, stir together the remaining 1 tablespoon granulated sugar and the cinnamon. Sprinkle about one third of this cinnamon sugar mixture over the bottom and sides of the buttered mug.
5. Pour half of the batter into the mug. Sprinkle another third of the cinnamon sugar evenly over the batter. Add the remaining batter, smooth the top if needed, and sprinkle the rest of the cinnamon sugar over the surface.
6. Microwave on high for 90 seconds. Check the cake; if wet batter remains on top, microwave in 10-second increments until cooked through. Serve warm from the mug or turn the cake out onto a plate. Garnish with extra cinnamon if desired.
Notes
If the baking powder is clumpy, break it apart before mixing it into the flour. Small pieces of unmixed baking powder can create a bitter taste.
Use a microwave-safe mug that holds at least 12 ounces so the batter has room to rise while cooking.
If the cake sticks when you try to unmold it, loosen the edges with a butter knife before turning it out.
