Key Ingredients for Mug Cake de Avena
- 1/3 cup rolled oats (old-fashioned work best)
- 1 large egg
- 2 tablespoons milk (any type)
- 1 tablespoon honey or maple syrup
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon baking powder
- Pinch of salt
- 1/4 teaspoon cinnamon (optional)
- 1 tablespoon mini chocolate chips or berries (optional)

Step-by-Step Instructions
Step 1: Prepare Your Mug Choose a microwave-safe mug that holds at least 12 ounces. Lightly grease it with butter or cooking spray to prevent sticking.
Step 2: Mix Dry Ingredients Add the oats, baking powder, salt, and cinnamon (if using) to your mug. Stir everything together with a fork to combine evenly.
Step 3: Add Wet Ingredients Crack the egg directly into the mug and whisk it well with the dry ingredients. Add the milk, honey, and vanilla extract. Mix until you have a smooth batter with no lumps.
Step 4: Add Optional Mix-ins If you’re using chocolate chips or berries, fold them in gently. Don’t overmix at this stage.
Step 5: Microwave Place the mug in the microwave and cook for 90 seconds. The cake should rise and look set on top. If it needs more time, microwave in 15-second intervals.
Step 6: Cool and Enjoy Let the mug cake cool for 1-2 minutes before eating – it will be very hot! Add your favorite toppings and enjoy immediately.

Top Tips for Perfecting Mug Cake de Avena
Don’t Overmix the Batter
Stir just until the ingredients are combined. Overmixing can make your mug cake tough and dense instead of fluffy and tender.
Choose the Right Oats
Old-fashioned rolled oats work best for texture. Quick oats will work in a pinch but may make the cake slightly mushy. Avoid steel-cut oats as they won’t cook properly in the microwave.

Watch Your Microwave Power
Microwave power varies significantly. Start with 90 seconds and adjust from there. High-powered microwaves may need only 75 seconds, while lower-powered ones might need up to 2 minutes.
Ingredient Substitutions
- No eggs? Use 1/4 cup applesauce or mashed banana
- Dairy-free? Any plant milk works great
- No honey? Try maple syrup, agave, or even sugar
- Want it sweeter? Add a tablespoon of your favorite jam
Common Mistakes to Avoid
Never use a mug smaller than 12 ounces – the cake will overflow. Also, don’t skip the pinch of salt; it enhances all the other flavors.
Storing and Reheating Tips
Immediate Consumption: This mug cake de avena is best enjoyed fresh and warm right after cooking. The texture and flavor are at their peak when served immediately.
Storing Leftovers: If you have leftovers (though unlikely!), cover the mug with plastic wrap and refrigerate for up to 2 days. The texture will change slightly but it’s still delicious.
Reheating Instructions: To reheat, microwave for 20-30 seconds. You can also enjoy it cold – it tastes like a dense, sweet oat bar.
Make-Ahead Option: Mix all dry ingredients in several mugs ahead of time. Store covered at room temperature for up to a week. When ready to eat, just add the wet ingredients and microwave.
Freezing: While not recommended, you can freeze the cooked cake for up to 1 month. Thaw overnight in the refrigerator and reheat before serving.

Frequently Asked Questions
Can I make this mug cake de avena without eggs?
Yes! Replace the egg with 1/4 cup of applesauce, mashed banana, or a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes).
Why did my mug cake turn out rubbery?
This usually happens from overcooking or using too much liquid. Start with less microwave time and adjust as needed. Also, make sure you’re using the right oat-to-liquid ratio.
Can I use instant oats instead of rolled oats?
Instant oats will work but may create a mushier texture. If using instant oats, reduce the milk slightly and watch the cooking time carefully.
How can I make this mug cake de avena vegan?
Use a flax egg or applesauce instead of the regular egg, and choose plant-based milk. Maple syrup works perfectly as a vegan sweetener.
Can I double this recipe?
Absolutely! Use a larger, microwave-safe bowl and increase the cooking time to 2-3 minutes, checking every 30 seconds after the first 90 seconds.
What’s the best mug size to use?
A 12-16 ounce mug works perfectly. The cake needs room to rise, so don’t use anything smaller than 12 ounces or it will overflow.
Can I add protein powder to this recipe?
Yes! Replace 2 tablespoons of oats with 1 scoop of vanilla protein powder. You might need to add an extra tablespoon of milk to maintain the right consistency.
Why didn’t my cake rise properly?
Make sure your baking powder is fresh (replace every 6 months). Also, don’t overmix the batter, and ensure you’re using enough liquid to create steam for rising.
