What Ingredients You Will Need

This recipe uses simple, everyday ingredients to make a delicious oatmeal muffin in a mug. Most of these are pantry staples, which means you can whip this up on a whim whenever the craving strikes.

• Quick oats: 3 tablespoons (rolled oats work too, but the texture will be slightly chewier).
• All-purpose flour: 2 tablespoons (or use almond flour for a gluten-free version).
• Baking powder: ½ teaspoon (helps the muffin rise).
• Ground cinnamon: ¼ teaspoon (for that warming flavor).
• Salt: A pinch (enhances the sweetness).
• Milk: 2 tablespoons (any kind works—dairy, almond, or oat milk).
• Maple syrup: 1 tablespoon (you can substitute with honey or agave syrup).
• Vanilla extract: ½ teaspoon (adds depth to the flavor).
• Optional mix-ins: Chocolate chips, raisins, chopped nuts, or fresh berries (about 1 tablespoon).

Feel free to play around with the ingredients to suit your dietary needs or flavor preferences. For example, you can swap the maple syrup for stevia or add a dash of nutmeg for extra spice.

Equipment Needed

One of the best things about this recipe is the minimal equipment required. Here’s everything you’ll need:

• Mug: A microwave-safe mug, ideally 12-16 ounces to avoid overflow.
• Fork or small whisk: Perfect for mixing the ingredients right in the mug.
• Microwave: This recipe is designed for quick cooking in the microwave.

If you don’t have a microwave, you can use a small oven-safe ramekin and bake it at 350°F (175°C) for about 12-15 minutes. Just make sure your mug or dish is suitable for the method you’re using!

Preparation Method

1. Start with the dry ingredients: In your mug, combine 3 tablespoons of quick oats, 2 tablespoons of all-purpose flour, ½ teaspoon of baking powder, ¼ teaspoon of ground cinnamon, and a pinch of salt. Stir until evenly mixed.
2. Add the wet ingredients: Stir in 2 tablespoons of milk, 1 tablespoon of maple syrup, and ½ teaspoon of vanilla extract. Mix until a thick batter forms.
3. Customize it: If you’re adding mix-ins like chocolate chips or dried fruit, fold them into the batter. Keep the total mix-ins to about 1 tablespoon.
4. Microwave time: Place the mug in the microwave and cook on high for 1½ to 2 minutes. Start with 90 seconds and check the texture—if the top is firm and springs back when lightly pressed, it’s done. If not, microwave in 10-second intervals until cooked.
5. Cool slightly: Let your muffin sit for 1 minute to cool before diving in—it’ll be hot right out of the microwave!

Pro tip: If your batter seems too thick before microwaving, add a splash of milk to loosen it up. And don’t overcook—this muffin is best if slightly soft and moist.

Cooking Tips & Techniques

• Don’t skip the pinch of salt: It may seem small, but it enhances the flavors of the muffin and balances the sweetness.
• Mix thoroughly: Use a fork or whisk to ensure there are no dry pockets of flour or oats in the batter.
• Adjust sweetness: If you prefer a sweeter muffin, increase the maple syrup slightly, but don’t go overboard or it might affect the texture.
• Watch the cooking time: Microwaves vary, so keep an eye on your muffin as it cooks. Overcooking can make it dry and tough.
• Experiment with toppings: A dollop of yogurt or a drizzle of nut butter can take this muffin to the next level.

Variations & Adaptations

This recipe is incredibly versatile—you can tweak it based on your taste preferences or dietary needs. Here are a few ideas:

• Gluten-free option: Swap the all-purpose flour for almond flour or a gluten-free blend.
• Vegan version: Use almond milk and substitute maple syrup with agave nectar.
• Seasonal twist: Add pumpkin puree and pumpkin spice for a fall-inspired muffin, or lemon zest and blueberries for a spring treat.
• Extra protein: Stir in a teaspoon of your favorite protein powder or a dollop of Greek yogurt.
• Chocolate lovers: Double the chocolate chips and sprinkle some on top before microwaving for a gooey, chocolatey finish.

Serving & Storage Suggestions

This oatmeal muffin is best enjoyed fresh and warm right out of the mug. Pair it with a cup of coffee or tea for a cozy breakfast or snack.

If you’re making it ahead of time, let the muffin cool completely before covering the mug with plastic wrap. It can be stored at room temperature for up to 1 day. For longer storage, transfer it to an airtight container and refrigerate for up to 3 days.

To reheat, microwave for 10-15 seconds to regain that fresh-from-the-microwave warmth.
