What You’ll Need

- ½ medium banana (ripe works best for mashing)
- 1 ½ tablespoons peanut butter (or any nut/seed butter of choice)
- ½ tablespoon honey (or agave for a vegan option)
- 1 tablespoon milk (any type: dairy, almond, oat, etc.)
- 4 tablespoons oats (rolled or quick oats both work)
- 1 tablespoon raisins (or substitute with seeds or nuts for added crunch)
How to Make It
- In a large microwavable mug, mash the banana well with a fork until smooth.
- Add the peanut butter, milk, and honey to the mug. Stir until everything is well combined.
- Mix in the oats and raisins (or your chosen add-ins) until evenly distributed.
- Microwave for 45 seconds to 1 minute, or until the top feels firm to the touch. (Note: Timing is based on a 1200-watt microwave; adjust as needed for your appliance.)
- Let it cool slightly, then enjoy warm straight from the mug!
Toppings and Mix-Ins to Elevate Your Mug Cookie
Customize your Microwave Breakfast Cookie with fun toppings and mix-ins! Try a drizzle of chocolate syrup or a sprinkle of chia seeds for extra flavor and texture. Swap raisins for dark chocolate chips or add a pinch of cinnamon for a cozy twist. The possibilities are endless!
Perfect Pairings for Your Morning Treat
Enjoy your mug cookie with a glass of cold milk or a cup of hot coffee for a balanced breakfast. Pair it with fresh fruit like sliced strawberries or blueberries for a refreshing touch. It’s a quick and satisfying way to start your day!
Quick Tips for the Best Mug Cookie
Use a ripe banana for natural sweetness and easy mashing. If your mug is small, reduce the oats slightly to avoid overflow. For a nut-free version, swap peanut butter with sunflower seed butter. And remember, microwaves vary, so start with 45 seconds and adjust as needed!
Storing and Reheating Your Cookie
If you have leftovers (unlikely!), store them in an airtight container in the fridge for up to 2 days. Reheat in the microwave for 15-20 seconds to enjoy it warm again. For a firmer texture, let it cool completely before storing.
