Ingredients You’ll Need
-
Egg Mixture:
- 1 large egg
- 3 tablespoons milk
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon ground cinnamon
- 1–2 teaspoons sugar (optional)
Additional Ingredients:
- 1 slice thick bread, cut into small cubes
- 1 teaspoon butter
- Optional: maple syrup, powdered sugar, or fresh fruit for serving
How to Make French Toast Mug
Step 1: Mix the Custard Base
Begin by grabbing your largest microwave-safe mug—this gives the bread plenty of room to soak up the custard without overflowing. Crack in the egg, pour in the milk, add the vanilla extract, ground cinnamon, and sugar if you like it sweet. Whisk everything together with a fork until well blended and slightly frothy. This is the magic mixture that soaks every bite with flavor from the inside out.
Step 2: Add the Bread Cubes
Toss your cubed bread right into the mug, making sure each piece gets coated. Gently push the bread down with your fork so it soaks up all that luscious custard. Don’t rush this step—the more the bread absorbs, the tastier your French Toast Mug will be. If the bread is extra stale, give it an extra minute to rest so it softens just right.
Step 3: Dot with Butter
Now it’s time for a little indulgence! Dot the top of the custard-soaked bread with tiny bits of butter. As your French Toast Mug cooks, the butter melts and soaks into the edges, giving you those classic, golden-brown hints you expect from the skillet version.
Step 4: Microwave to Perfection
Pop your mug into the microwave and cook on high for one minute. Open the door and check—if the custard is still wet, keep going in 15-second bursts. Depending on your microwave, total cooking time usually ranges from 1 1/2 to 2 minutes. The French Toast Mug is done when the bread looks set and puffs slightly, but isn’t stiff or dry. Let it cool for a minute or two so you don’t scorch your tongue with the first bite!
How to Serve French Toast Mug

Garnishes
The crowning touch for your French Toast Mug is, of course, a splash of maple syrup—let it pool and trickle through every nook and cranny. For a classic look, dust with powdered sugar or toss on fresh fruit. A handful of berries or sliced banana instantly makes your mug breakfast brunch-worthy.
Side Dishes
If you want to round out your meal, pair your cozy French Toast Mug with a scoop of Greek yogurt or a simple cup of coffee. Crispy bacon, sausage patties, or even a handful of nuts on the side can balance out the sweet richness with savory notes. For brunch, try serving with a fruit salad to add a touch of freshness.
Creative Ways to Present
The beauty of this mug recipe is its cute, personal size. Serve your French Toast Mug right in the microwave-safe mug, or, to dress things up, turn it out onto a small plate and drizzle with your favorite sauce. You could even create a make-your-own topping bar so everyone personalizes their mug with nuts, chocolate chips, or whipped cream—perfect for kids or brunch guests!
Make Ahead and Storage
Storing Leftovers
If you’ve made a couple of French Toast Mugs or couldn’t finish yours, simply cover the mug and store it in the refrigerator for up to 24 hours. It’s best enjoyed fresh, but it certainly won’t go to waste—just save it for a sweet snack later.
Freezing
French Toast Mug isn’t the best candidate for freezing because bread can become soggy when thawed. If you do want to freeze extras, let them cool completely, wrap tightly, and store for up to a week. Reheat directly from frozen, adding a splash of milk before microwaving to restore moisture.
Reheating
To revive your leftover French Toast Mug, microwave it in 15-second increments until hot and steamy. If it appears a little dry, drizzle in a teaspoon of milk before reheating and give it a quick stir to fluff things back up. Top again with syrup or fruit, and it’ll taste just as good as fresh!
FAQs
Can I make this French Toast Mug dairy-free?
Absolutely! Swap regular milk for any non-dairy variety, like almond, oat, or soy milk. Use a plant-based butter or simply omit the butter altogether—the French Toast Mug will still be deliciously custardy.
What type Breakfast, Snack
Stale, thick-cut bread is ideal because it soaks up the egg mixture without falling apart. Brioche, challah, or even sturdy sandwich bread give fantastic results with a soft, slightly chewy texture in your French Toast Mug.
How can I make a richer, more decadent French Toast Mug?
To amp up the indulgence, use half-and-half instead of milk, choose buttery brioche or challah, and don’t skimp on the butter. Add a sprinkle of chocolate chips or a swirl of Nutella before microwaving for a true treat.
Can I double the recipe for two servings?
Definitely! Simply divide the ingredients between two large mugs and cook them separately. If you try to make two servings in one mug, it won’t cook evenly and may overflow. Sharing the French Toast Mug magic is easy—everyone gets their own!
Why did my French Toast Mug turn out soggy or rubbery?
This usually happens if there’s too much liquid relative to bread, or if you overcook it. Make sure to use thick, sturdy bread and check the mug after a minute. Stop microwaving as soon as it’s set but still soft for the perfect texture.
Final Thoughts
Give the French Toast Mug a try next time the craving for something sweet, warm, and homemade hits—especially when time isn’t on your side. It’s a breakfast hug in a cup, calling out for your favorite toppings, ready in minutes, and almost too easy not to whip up. You’ll never look at your morning slice of bread the same way again!
