How to Store and Freeze Brownie in a Mug

Freezer: Although best enjoyed fresh, you can freeze a cooled brownie in a mug for up to 1 month. Wrap tightly in plastic wrap and then place in a freezer bag for protection against freezer burn.

Brownie in a Mug Recipe FAQs
How do I choose the right flour for my brownie in a mug?
Absolutely! All-purpose flour works well, but if you’re looking to make a gluten-free version, I recommend substituting it with almond flour. Just be aware that almond flour might make the brownie slightly denser, so you might want to reduce the amount slightly or add a bit more liquid.
What's the best way to store my brownie in a mug leftovers?
Very! While brownies are best enjoyed fresh, if you have leftovers, store your brownie in a mug in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy it again, reheat it in the microwave for about 10 to 15 seconds to bring back that delicious gooey texture.
Can I freeze my brownie in a mug?
For sure! To freeze, let the brownie cool completely, then wrap it tightly in plastic wrap and place it in a freezer bag to protect it from freezer burn. It can last in the freezer for up to 1 month. When you’re ready to savor it, thaw it in the fridge overnight, and give it a quick zap in the microwave for about 20 to 30 seconds to warm it up.
What should I do if my brownie in a mug overflows in the microwave?
Don’t worry, it happens! To prevent overflow, make sure you’re using a larger mug, ideally one that holds at least 12 ounces. Additionally, keep a close eye on it while it’s microwaving. If it starts to rise too much, turn the microwave off for a moment and let it settle before continuing.
Is this brownie in a mug safe for my allergies?
Great question! If you’re cooking for someone with allergies, you can easily adapt the recipe. Use gluten-free flour for those with gluten sensitivities, and substitute sugar with a sugar alternative if necessary. Just be sure to check the packaging for cross-contamination warnings.
Can I make this brownie in a mug lactose-free?
Absolutely! To enjoy a lactose-free brownie, simply substitute the vegetable oil for melted coconut oil and skip the chocolate chips if they’re dairy-based. There are plenty of dairy-free chocolate chip options available if you want that extra chocolatey goodness!
