Main Ingredients to Make this Vegan Mug Brownie

Almond butter: Almond butter is a nutritious alternative to traditional butter. It adds a rich, nutty flavor and a creamy texture to the brownie batter. Plus, it’s a good source of healthy fats, protein, and fiber. It makes these a healthier option for those who are looking for a more wholesome treat. If you have a nut allergy or prefer a different type of nut butter, you can easily substitute it! Peanut butter, cashew butter, tahini or sunflower seed butter would all be good options!

Coconut sugar: Coconut sugar is a natural sweetener that is derived from the sap of coconut palm trees. It has a lower glycemic index compared to regular sugar. That means it may have a less significant impact on blood sugar levels. Coconut sugar also adds a rich, caramel-like flavor to the brownie batter, giving it a unique taste profile. If you don’t have coconut sugar, you can substitute it with brown sugar no problemo.

Maple syrup: Maple syrup is a delicious natural sweetener that adds a deep, rich sweetness to the brownies. It also adds moisture to the batter, helping to keep the brownies soft and fudgey. Maple syrup is a good source of antioxidants and minerals, making it a healthier option compared to processed sugars. If you don’t have maple syrup, you can use other liquid sweeteners like honey or agave nectar..

Cocoa: Cocoa powder is an essential ingredient in brownies, as it provides the rich, chocolatey flavor that we all love. It also adds depth and complexity to the overall taste of the brownies. Look for high-quality, unsweetened cocoa powder for the best flavor. If you prefer a sweeter brownie, you can use sweetened cocoa powder.

How to Make a Brownie in the Microwave

Mix. Combine the almond butter, coconut sugar, maple syrup, cocoa powder, baking powder, and a pinch of salt. Use a whisk or a rubber spatula to mix the ingredients until incorporated. Make sure to scrape the sides and bottom of the bowl to ensure all the ingredients are fully incorporated.

Dish. Spoon the brownie batter into a microwave safe bowl or baking dish. Spread it evenly to create a smooth layer.

Microwave it. Place the bowl or dish with the brownie batter into the microwave and cook on high heat for 40 seconds. Cooking times may vary depending on the wattage of your microwave. Keep an eye on the brownie as it cooks to avoid overcooking. When done, the brownie may still be gooey in the center, which is what makes it delicious!

Chip it. Sprinkle a few extra chocolate chips on top of the hot brownie. Allow them to melt slightly and create a gooey, chocolatey topping. You can also add a sprinkle of flaky salt on top for a sweet and salty vibe.

Cool. Let the brownie sit for about a minute to cool slightly and set before digging in. This will allow the brownie to firm up slightly and make it easier to handle. The waiting time can be a challenge, but it’s worth it for that perfect texture!

Tips for a Successful Vegan Mug Brownie

Use a microwave-safe bowl or baking dish: Avoid using metal or non-microwave-safe containers. They can cause sparks or other safety hazards in the microwave.

Watch the cooking time: Cooking times can vary depending on the wattage of your microwave. Keep a close eye on the brownie as it cooks. It’s better to slightly undercook the brownie in the microwave, as it will continue to cook and firm up as it cools.

Let it rest: Once the brownie is cooked, resist the temptation to dig in right away! Let it sit for about a minute to cool slightly and set. This will help the brownie firm up slightly and make it easier to handle.

Customize with toppings: Feel free to get creative with toppings! Sprinkle some extra chocolate chips, nuts, or flaky salt on top of the hot brownie. You can also drizzle some melted chocolate, caramel, or peanut butter for an extra indulgent touch.

Variations on this Vegan Mug Brownie

Nutella swirl.

Drop spoonfuls of Nutella or any other hazelnut chocolate spread on top of the batter. Use a toothpick or a skewer to swirl the Nutella into the batter for a marbled effect.

Mint chocolate chip.

Add a few drops of peppermint extract to the brownie batter for a refreshing twist. Stir in some mini chocolate chips or chop up some chocolate mints and fold them into the batter before microwaving.

Nutty crunch.

Add chopped walnuts, pecans, or almonds, to the brownie batter for added crunch and texture.

Shredded coconut.

Stir in some shredded coconut or sprinkle it on top of the brownie for an almond joy inspired brownie.

Salted caramel.

Drizzle some salted caramel sauce on top of the brownie before microwaving for a heavenly sweet and salty combination.

Espresso or coffee.

Add a teaspoon of instant coffee or espresso powder to the brownie batter for a hint of coffee flavor.

How to Store & Reheat

Ideally, you eat the brownie immediately and you eat the whole thing. You can also prep the brownie batter and store it until a later time when you’re ready to microwave it.

If you do have leftover mug brownie, allow the brownie to cool completely in the microwave-safe mug or bowl.

Once cooled, cover the mug or bowl tightly with plastic wrap or transfer the brownie to an airtight container.

Store the brownie in the refrigerator for up to 2-3 days. Or, pop it in the freezer for up to 1 month, depending on your preference and desired freshness.

To reheat a microwave mug brownie, you have a few options:

1. Microwave. Remove the plastic wrap or transfer the brownie from the airtight container back to a microwave-safe mug or bowl. Microwave the brownie on medium power in short intervals, such as 10-15 seconds at a time. Stop microwaving once the brownie is warmed to your liking. Be careful not to overheat, as it may result in an overcooked or dried-out brownie.
2. Oven. If you prefer to use the oven, preheat your oven to 350°F (175°C). Transfer the brownie from the airtight container to an oven-safe dish or oven-safe mug. Bake it in the preheated oven for about 5-10 minutes, or until warmed through.
3. Eat it cold. Alternatively, you can also enjoy the mug brownie cold, straight from the refrigerator. It will have a fudgey and chilled texture, which can be quite delicious and refreshing on a hot day.
