FULL RECIPE — STEP BY STEP
1. Choose the right mug
Use a microwave-safe mug with at least 300–350 ml capacity.
Don’t fill it more than about halfway with batter because the bread will rise during cooking. A larger/taller mug helps prevent overflow.

2. Melt the butter
Put 1 tablespoon butter into the mug.
Microwave for approximately 10–15 seconds, just until melted.
Swirl the butter around the bottom and sides of the mug.
Tip: Don’t make the butter boiling hot because it can partially cook the egg when you add it.
3. Add the egg
Crack 1 egg into the mug.
Beat it thoroughly with a fork for about 20–30 seconds.
You want the yolk and white completely combined.
4. Add milk
Add:
1 tbsp milk
1 tsp sugar
⅛ tsp salt
vanilla, if using
Mix well.
5. Add flour and baking powder
Add:
4 tbsp flour
½ tsp baking powder
Mix with the fork until you have a smooth, thick batter.
Scrape the bottom and corners of the mug so there are no pockets of dry flour.
Don’t beat the batter for several minutes. Just mix until everything is incorporated.
What should the batter look like?
It should look like a thick muffin batter.
Too thick?
Add 1 teaspoon milk.
Too thin?
Add 1 teaspoon flour.
The exact amount can vary slightly depending on the flour and egg size.
6. Microwave
Place the mug in the center of the microwave.
Cook on HIGH.
Starting point:
60 seconds
Check it.
If the center is still wet, continue cooking in 10-second intervals.
Most mug-bread recipes fall around 60–90 seconds, although microwave wattage makes a substantial difference.

Important
Don’t automatically cook it for several minutes.
Microwave cooking continues rapidly, and overcooking can make this type of bread rubbery or dry.
7. Check for doneness
The top should look:
risen
dry
lightly golden
firm when gently touched
Insert a toothpick into the center.
If it comes out with wet batter, microwave another 10 seconds.
If it comes out with a few moist crumbs, it’s ready.
8. Rest the bread
Leave the mug alone for 1–2 minutes.
This allows the internal steam to settle.
Similar mug-bread recipes recommend a short resting period before turning the bread out.

9. Remove from the mug
Run a butter knife around the edge.
Turn the mug upside down onto a plate or cutting board.
Tap gently.
The bread should slide out.
Let it cool for another minute.
10. Slice
Cut into 2–3 thick slices.
For the exact appearance in your photo, slice the round loaf horizontally into thick pieces.
Spread with butter while warm.
The butter will melt into the tiny holes in the crumb.
EXTRA-FLUFFY VERSION
For a softer, more cake-like bread:
4 tbsp flour
½ tsp baking powder
1 egg
1 tbsp melted butter
2 tbsp milk
1 tsp sugar
pinch salt
Microwave for 60–80 seconds, checking after 60 seconds.
This version is especially good with honey or jam.
SAVORY MUG BREAD
If you want actual bread flavor rather than sweet cake flavor, use:
4 tbsp flour
½ tsp baking powder
1 egg
1 tbsp melted butter or olive oil
1 tbsp milk
⅛ tsp salt
¼ tsp garlic powder
¼ tsp dried oregano
Don’t add sugar or vanilla.
After cooking, slice and toast in a dry skillet for 1–2 minutes per side.
That gives it a much more bread-like crust.
CHEESE VERSION
Add:
2 tbsp shredded cheddar
½ tsp Italian seasoning
pinch of black pepper
Mix into the batter.
You can also put 1 teaspoon mozzarella in the center before microwaving for a melted-cheese center.
BANANA VERSION
For a sweet breakfast:
4 tbsp flour
½ small ripe banana, mashed
½ tsp baking powder
1 egg
1 tbsp milk
1 tsp melted butter
½ tsp cinnamon
1 tsp honey or sugar
Microwave approximately 70–90 seconds.
GLUTEN-FREE VERSION
Use:
4 tbsp almond flour
½ tsp baking powder
1 egg
1 tbsp melted butter
pinch salt
Almond-flour microwave breads are a well-established variation and are typically cooked for around 60–90 seconds.

Note: Almond flour produces a moister, denser bread than wheat flour.
KETO / LOW-CARB VERSION
For a low-carb version:
4 tbsp finely ground almond flour
½ tsp baking powder
1 egg
1 tbsp butter
pinch salt
Microwave about 60–90 seconds.
For a less eggy flavor, you can use an egg white, though the texture changes. Microwave mug-bread recipes commonly use almond or coconut flour as alternatives to wheat flour.

OVEN VERSION
If you don’t want to use a microwave:
Mix the batter as above.
Transfer to a small greased oven-safe ramekin.
Bake at 350°F / 175°C.
Bake approximately 12–18 minutes.
Check the center with a toothpick.
Cool for 2–3 minutes.
Remove and slice.
The oven gives you a slightly more bread-like crust.
HOW TO MAKE IT LOOK LIKE THE PHOTO
For that high, rounded top:
Use a relatively narrow/tall mug.
Don’t make the batter too thin.
Use fresh baking powder.
Mix the egg thoroughly.
Don’t overmix after adding flour.
Microwave immediately after mixing.
Don’t overcook.
Let it rest before removing it.
The bread in the photo has a very fine, evenly aerated crumb, which is helped by thoroughly combining the egg and baking powder while avoiding excessive cooking.

These are estimates. The actual values depend on egg size, flour, butter and milk.
Adding jam, honey, cheese or additional butter will increase the calories.
Q&A
Why did my mug bread become rubbery?
Usually because it was overcooked.
Microwave it only until the center is set. Start checking around 60 seconds and continue in 10-second increments.
Why didn’t it rise?
Possible causes:
old baking powder
batter was too heavy
insufficient baking powder
egg wasn’t mixed well
microwave power was too low
too much liquid
Fresh baking powder makes a noticeable difference.
Why is the middle wet?
Give it another 10 seconds.
Don’t immediately add another full minute because the outside can become tough before the center finishes.
Why is it dry?
Too much flour or too much microwave time.
Measure flour with a spoon and level it rather than packing it tightly into the spoon.
Can I make it without an egg?
Yes, but the texture will be different.
The egg provides structure, moisture and helps the bread rise. Egg-free versions generally need a different combination of liquid and leavening.
Can I use whole-wheat flour?
Yes.
Replace half the all-purpose flour with whole-wheat flour initially. Using 100% whole-wheat flour can make this small bread noticeably denser.
Can I use oat flour?
Yes.
Use finely ground oat flour and expect a softer, more tender texture.
Can I use coconut flour?
Yes, but don’t substitute it 1:1 for wheat flour.
Coconut flour absorbs dramatically more liquid. Recipes specifically designed for coconut flour use much smaller quantities.
O

Can I use almond flour?
Yes. Use finely ground almond flour.
The result will be more moist and tender and less chewy than wheat-flour bread.
P
Piccola Cucina
Can I make it without butter?
Yes.
Use 1 tbsp neutral oil instead.
Olive oil works for a savory version.
Can I make it dairy-free?
Yes.
Replace butter with neutral oil or dairy-free butter and replace milk with plant milk.
Can I make it sugar-free?
Yes.
Simply omit the sugar for savory bread.
Can I make it ahead?
It’s best fresh.
Microwave bread tends to lose moisture as it sits. If you make it ahead, cool it completely and store it sealed.
Can I refrigerate it?
Yes, for about 1–2 days for best quality.
Reheat briefly, then toast it.
Can I freeze it?
Yes.
Slice it first, separate the slices with parchment, and freeze in an airtight container.
Toast or warm after thawing.
Can I toast it?
Yes—and I highly recommend it.
Microwave mug bread can be soft immediately after cooking. Toasting the slices in a skillet or toaster gives the outside a much more satisfying crisp texture. Similar 90-second bread recipes specifically recommend toasting for improved texture.
L
Low Carb with Jennifer
Can I put butter inside before cooking?
Yes.
Put ½–1 teaspoon butter in the center of the batter and cover it completely.
You’ll get a soft buttery pocket when you cut it open.
Can I add chocolate?
Yes.
Add 1–2 tbsp chocolate chips for a sweet version.
Can I add nuts?
Yes.
Add 1 tbsp chopped walnuts, almonds or pecans.
For a nut-free recipe, simply omit them.
Can children make this?
The ingredients are simple, but the mug and bread become extremely hot. Children should have adult supervision around the microwave and hot mug.

Best Formula to Remember
For the easiest version, remember:
4 tbsp flour + ½ tsp baking powder + 1 egg + 1 tbsp butter + 1 tbsp milk + pinch salt → mix → microwave 60–90 sec → rest → slice → butter.
That is the simplest route to the fluffy mug bread shown in your picture. Similar established recipes use essentially this same flour/egg/fat/leavener
