Pinch of salt	A small pinch
Cinnamon (optional)	1/4 tsp

Equipment Needed

Microwave-safe mug: The foundation of your mug cake; ensure it’s at least 12 oz to prevent overflowing.
Fork or small whisk: For mixing the batter directly in the mug.
Measuring spoons: Precision matters in mug cake baking for consistent results.
Microwave: The magic tool that transforms batter into cake in minutes.

Step-by-Step Instructions

Prepare the Mug: Lightly grease the inside of your microwave-safe mug with cooking spray, melted butter, or coconut oil to prevent sticking.
Mix the Dry Ingredients: Add the blended oat flour, all-purpose flour, baking powder, brown sugar, salt, and cinnamon (if using) into the mug. Stir well to combine.
Add Wet Ingredients: Pour in the milk, melted butter (or coconut oil), and vanilla extract. Stir until everything is well combined and no lumps remain.
Incorporate Add-ins: If using chocolate chips, nuts, or fruit, fold them gently into the batter.
Microwave the Mug Cake: Place the mug in the microwave and cook on high for 90 seconds to 2 minutes, depending on the power of your microwave. Start with 90 seconds and add more time in 10-second increments if needed.
Check Doneness: The cake should rise and feel springy to the touch. Be careful, as the mug will be hot.
Cool and Serve: Let the cake sit for a minute before digging in. Add a dollop of whipped cream, a sprinkle of powdered sugar, or a drizzle of honey if desired.

Tips and Variations

Texture Tip: Avoid overcooking, as this can make the cake rubbery. Start with shorter cooking times and adjust as necessary.
Flavor Boost: Add a teaspoon of peanut butter or Nutella before microwaving for an extra creamy center.
Fruity Delight: Toss in fresh berries or sliced bananas for a refreshing twist.
Spice It Up: Add a pinch of nutmeg or pumpkin spice for a seasonal touch.
Protein Boost: Mix in a scoop of protein powder for a high-protein snack.

Serving Suggestions

Oatmeal mug cake shines best when served warm, straight from the microwave. For added indulgence:

Top with a scoop of vanilla ice cream.
Drizzle caramel sauce or maple syrup over the top.
Sprinkle toasted nuts or shredded coconut for extra crunch.
Add fresh berries or sliced bananas for a fruity flair.

Pair your mug cake with a cozy drink—hot coffee, chai latte, or a glass of cold milk make excellent companions.

Pairings

The warm and mildly sweet flavor of oatmeal mug cake pairs wonderfully with a variety of beverages:

Coffee: A cappuccino or a strong espresso balances the cake’s sweetness.
Tea: Try it with chai tea or a cinnamon-infused black tea for a harmonious pairing.
Hot Chocolate: Double up on coziness with a rich cup of hot cocoa.
Smoothies: A banana or berry smoothie complements the texture and flavor beautifully.

Storage and Reheating

Oatmeal mug cakes are designed to be eaten fresh, but if you have leftovers:

Refrigeration: Cover the mug tightly with plastic wrap and store it in the fridge for up to 1 day.
Reheating: Microwave for 20-30 seconds until warmed through.
Note: The cake may dry out slightly upon reheating, so consider adding a splash of milk before warming.
