This Healthy 5-Minute Instant Oatmeal Mug Cake recipe is quick and easy to make. With six simple ingredients—including One Degree’s new flavored Instant Oatmeals—it’s just as good for dessert as it is for a quick breakfast or an afternoon snack. The generous single-serving portion makes this a quick and comforting snack to make for yourself after a long day. And to make the end of a long day shorter, this recipe requires minimal cleanup; all you need is a mug, a blender, and a spoon!

You can use your favorite non-dairy milk, fresh, dried, or frozen fruits, nuts, seeds, and a scoop of plant-based protein powder to make whatever flavor your tastebuds desire. This recipe is totally customizable, simple, and kid-friendly.

This Instant Oatmeal Mug Cake recipe creates a great opportunity to get kids into cooking at an early age. Kids of all ages can help in the kitchen—even the littlest can help with this one by peeling the banana or pushing the buttons on the blender and microwave. And it’s a fun and safe make-it-yourself snack for older kids, too. So easy in fact, they could whip up a few extra portions to share a sweet surprise with you and the people they love.

Not a fan of chocolate? Substitute one of our other sprouted Instant Oatmeals to change the flavor entirely. Try using our Sprouted Apple Cinnamon Instant Oatmeal and garnish the dish with chunks of fresh apple and a dash of cinnamon or brown sugar.

Gluten-free Instant Oatmeal Mug Cake Recipe with One Degree Organics Sprouted Cacao Nib Instant Oatmeal


2/3 cups One Degree Organics Instant Oats (any flavor)
1 banana, peeled
1 tsp maple syrup or honey
2/3 cup non-dairy milk
1 tsp baking powder

Optional: 1 scoop of plant-based protein powder


Add all ingredients into blender and blend until smooth and mixed well.

Grease a microwave safe mug or ramekin with your go-to oil or some melted vegan butter.

Pour mixture into mug or ramekin.

Microwave for 1–3 minutes on high, until cake is fluffy and cooked through. (Test for doneness with a toothpick).

This recipe makes 2 servings (or one very generous portion!).


Double up on the chocolate flavor with our Sprouted Cacao Nib Instant Oatmeal and add semi-sweet chocolate chunks before microwaving. Garnish with freshly sliced strawberries or raspberries.

This recipe is portioned for one large mug or ramekin but scales up easily to feed more (just double or triple the recipe).

Because not all mugs or ramekins are the same size, make sure you do not put too much of the mixture in yours before cooking, so it does not overflow as it expands during the short microwave cook time. (We used a 10–12 ounce ramekin and poured in half of the mixture to make one satisfying snack-sized portion).

Don’t microwave? Bake your Instant Oatmeal Mug Cake in the oven. To make this recipe without a microwave, use an oven-safe ramekin instead of a mug and bake at 350 degrees F for 15–25 minutes. (Cake is cooked when fluffy and a toothpick poked in the center comes out clean).
