Apple Mug Cake (Gluten Free, Paleo, Nut Free Option) Recipe
Introduction
This Apple Mug Cake is a quick and delicious treat that’s both gluten-free and paleo-friendly. Perfect for when you want a warm, comforting dessert in minutes without any fuss. Plus, there’s a nut-free option to suit different dietary needs.

Ingredients
- 3 tablespoons finely ground almond flour (or sunflower seed flour or Otto’s cassava flour as a 1:1 nut-free replacement)
- ½ teaspoon ground cinnamon
- ⅛ teaspoon baking soda (or scant ½ teaspoon baking powder; use baking powder with sunflower seed flour to prevent green coloring)
- ⅛ teaspoon Diamond Crystal kosher salt
- 1 tablespoon applesauce
- 2 teaspoons honey (or 2½ teaspoons maple syrup)
- 1 teaspoon avocado oil (or melted refined coconut oil or ghee)
- ⅛ teaspoon vanilla extract
- 1 large egg
Instructions
- Step 1: In a microwave-safe mug, combine the almond flour (or chosen flour), ground cinnamon, baking soda (or powder), and kosher salt. Mix well to evenly distribute the dry ingredients.
- Step 2: Add the applesauce, honey (or maple syrup), avocado oil (or coconut oil/ghee), vanilla extract, and the large egg to the mug. Stir thoroughly until you get a smooth batter without lumps.
- Step 3: Microwave the mug cake on high for about 60 to 90 seconds, checking at 60 seconds by inserting a toothpick—if it comes out clean, the cake is done; if not, microwave in 10-second intervals.
- Step 4: Let the mug cake cool for a minute or two before enjoying it straight from the mug or turning out onto a plate.
Tips & Variations
- Use baking powder instead of baking soda if making the nut-free version with sunflower seed flour to avoid the cake turning green.
- For extra flavor, add a pinch of nutmeg or a handful of chopped apples before microwaving.
- If you prefer a sweeter cake, increase the honey or maple syrup by half a teaspoon.
- Swap the avocado oil with melted ghee for a buttery taste that stays paleo-friendly.
Storage
This mug cake is best enjoyed fresh but can be stored covered in the refrigerator for up to 2 days. Reheat gently in the microwave for about 20 seconds before serving to warm it back up without drying out.

FAQs
Can I make this apple mug cake vegan?
This recipe calls for an egg which is key for structure; however, you can try replacing it with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and see how the texture turns out, though it may be slightly different.
What if I don’t have applesauce?
If you don’t have applesauce, mashed banana can be a good substitute in equal amounts, adding natural sweetness and moisture.

Ingredients
Dry Ingredients
- 3 tablespoons finely ground almond flour or 3 tablespoons sunflower seed flour or Otto’s cassava flour (1:1 nut-free replacement)
- ½ teaspoon ground cinnamon
- ⅛ teaspoon baking soda or ½ teaspoon baking powder (use baking powder if using sunflower seed flour to prevent green color)
- ⅛ teaspoon Diamond Crystal kosher salt
Wet Ingredients
- 1 tablespoon applesauce
- 2 teaspoons honey or 2½ teaspoons maple syrup
- 1 teaspoon avocado oil or melted refined coconut oil or ghee
- ⅛ teaspoon vanilla extract
- 1 large egg
Instructions
- Prepare the Mug: Lightly grease a microwave-safe mug with avocado oil or melted coconut oil to prevent sticking.
- Mix Dry Ingredients: In a small bowl, combine the almond flour (or chosen substitute), ground cinnamon, baking soda or baking powder, and kosher salt. Stir well to evenly distribute the leavening agent and spices.
- Combine Wet Ingredients: In another bowl, whisk together the applesauce, honey or maple syrup, avocado oil or melted coconut oil/ghee, vanilla extract, and the large egg until smooth and well incorporated.
- Combine Wet and Dry Mixtures: Pour the wet ingredients into the dry ingredients and stir gently until just combined, being careful not to overmix to ensure a tender cake.
- Microwave Cooking: Pour the batter into the prepared mug and microwave on high for about 60 to 90 seconds, or until the cake has risen and a toothpick inserted into the center comes out clean. Microwaves vary, so start with 60 seconds and add more time if needed in 10-second increments.
- Cool and Serve: Let the mug cake cool for a minute or two after microwaving, then enjoy straight from the mug or tip out onto a plate. Optionally, serve with a sprinkle of cinnamon or a spoonful of yogurt.
Notes
- Use baking powder if using sunflower seed flour to prevent the cake from turning green.
- Adjust cooking time based on your microwave’s power to avoid overcooking or undercooking.
- This recipe can be customized with your favorite spices or add-ins like chopped nuts or dried fruit.
- For a vegan alternative, substitute the egg with a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water, let sit for 5 minutes) and use maple syrup as the sweetener.
