Kids Can Bake: Bread in a Bag

Ingredients

Stage 1: The Yeast Batter

This goes in the bag first. The yeast activates in warm water with sugar and a little flour, creating a bubbly batter you can see through the bag.

• 130g (1 cup) all-purpose flour
• 240g (1 cup) warm water (like a warm bath, not hot)
• 7g (2¼ teaspoons) instant yeast
• 35g (3 tablespoons) sugar

Stage 2: The Rest of the Dough

After the yeast gets going, you add the rest of the ingredients to the same bag and squish until it becomes real dough.

• 270g (2 cups) all-purpose flour
• 8g (1½ teaspoons) salt
• 40g (3 tablespoons) olive oil or melted butter

For the Pan

A little oil or butter to keep the bread from sticking.

• 5g (1 teaspoon) butter or oil (for greasing the pan)

Total flour: 400g

Hydration: 60%

Pro tip: Use a heavy-duty freezer bag, not a regular sandwich bag. Regular bags will split when you start squishing. Ask me how I know.

Equipment

Method

Stage 1: The Yeast Batter (Mix it in the bag and watch it come alive)

This is where the magic starts. You're going to put the first round of ingredients into a zip-top bag, seal it up, and squish it all together. Then you'll watch the yeast wake up and start making bubbles right inside the bag. It's like a science experiment you can eat.

1. Add the first ingredients to the bag. Open your gallon-size zip-top bag and add 1 cup of flour, 3 tablespoons of sugar, 2¼ teaspoons of instant yeast, and 1 cup of warm water. The water should feel like warm bath water on your finger. Not hot.
2. Seal the bag and squish. Push most of the air out of the bag and seal it tight. Now squish, squeeze, and shake the bag until everything is mixed together. You'll have a thin, pancake-batter-like mixture. That's exactly right.
3. Let the yeast wake up. Set the bag on the counter (sealed) and wait about 10 minutes. Watch what happens. The bag will start to puff up as the yeast produces carbon dioxide gas. The batter will get bubbly and foamy. That inflating bag is proof that your yeast is alive and working.

Wait: PT10M

Tip: If the bag doesn't puff up after 10 minutes, your yeast might be dead or your water was too hot. Open the bag, check the temperature of the mixture (it should be warm, not hot), and try again with fresh yeast if needed.

Stage 2: Add the Rest and Squish (From batter to dough, all inside the bag)

Now you'll add the remaining flour, salt, and fat to the bag. This is where the batter transforms into actual dough. You'll feel it happen through the plastic.

1. Add the remaining ingredients. Open the bag and add 2 cups of flour, 1½ teaspoons of salt, and 3 tablespoons of olive oil or melted butter. Don't dump all the flour in at once. Add about half, seal, squish. Then add the rest, seal, squish again.
2. Squish until it becomes dough. Seal the bag and start squishing. At first it will feel like a sticky mess. Keep going. Squeeze it, fold the bag over itself, press it flat, fold it again. After a couple minutes, you'll feel it change. The dough will start pulling away from the sides of the bag. It will feel like a smooth, firm ball instead of a gooey paste. That moment when it changes is gluten forming.
3. Check your dough. When the dough feels smooth and pulls cleanly away from the bag walls, it's ready. Open the bag and poke it. It should feel like a firm stress ball, smooth on the outside and slightly springy. If it's still very sticky, add 1 tablespoon of flour at a time and squish more.

Tip: The transition from sticky batter to smooth dough happens fast. One minute it's a mess, the next it's a ball. Keep squishing and you'll feel the exact moment it comes together.

Knead It for Real (Time to get your hands in the dough)

The bag got you most of the way there, but now it's time for a few minutes of real hand kneading. This is the part that feels like playing with the world's best play-dough.

1. Dump the dough out. Sprinkle a tiny bit of flour on a clean countertop or table. Open the bag and turn it inside out over the surface, letting the dough fall out. It should come out pretty clean.
2. Knead for 5 minutes. Push the dough away from you with the heel of your hand. Fold it back toward you. Turn it a quarter turn. Repeat. Keep going for about 5 minutes. The dough should feel smooth, elastic, and slightly warm from your hands. It should not stick to the counter. If it does, add a tiny pinch of flour.
3. The poke test. Poke the dough with your finger. If it slowly springs back and leaves just a small dent, it's ready. If it springs back fast and hard, knead a little more. If it doesn't spring back at all, you've over-kneaded (rare with hand kneading, so don't worry too much).

Tip: This is supposed to be fun. Push, fold, turn. Push, fold, turn. You'll feel the dough get smoother and more alive under your hands. Some kids say it feels like it's breathing. That's the gluten doing its thing.

Shape Your Loaf (From ball to bread)

Now you'll shape your dough into a loaf and put it in a pan. The shape you make now is the shape your bread will be when it's done.

1. Grease your pan. Rub a little butter or oil inside your loaf pan so the bread doesn't stick. Get the bottom and all four sides.
2. Shape the dough. Pat your dough into a flat rectangle, roughly the width of your loaf pan. Now roll it up tightly from one short end to the other, like a sleeping bag. Pinch the seam closed with your fingers. Tuck the ends under. Place it seam-side down in the greased pan.
3. No loaf pan? No problem. If you don't have a loaf pan, shape the dough into a round ball (a boule) and place it on a parchment-lined baking sheet. It'll bake into a rustic round loaf instead of a sandwich loaf. Both are great.

Tip: When you roll the dough up, roll it tight. Loose rolling creates big air gaps inside the loaf. Tight rolling gives you an even crumb with consistent texture from crust to crust.

The Final Rise (Let the yeast do its thing one more time)

Cover your pan and let the dough rise until it's peeking above the rim. This is proofing, the last rise before baking.

1. Cover and wait. Cover the loaf pan loosely with a clean towel or plastic wrap. Set it somewhere warm. The dough needs about 30-45 minutes to rise. You're looking for it to puff up until it's just above the rim of the pan. It should look pillowy and soft.
2. Check if it's ready. Gently poke the side of the dough with a floured finger. If it springs back slowly and leaves a small indent, it's ready to bake. If it snaps back quickly, give it another 10 minutes.

Wait: PT40M

Bake Your Bread (From dough to a real loaf of bread)

This is it. Your bag of flour, water, yeast, and a little patience is about to become an actual loaf of bread.

1. Preheat the oven (ADULT). An adult preheats the oven to 375°F (190°C). Make sure the rack is in the middle position.
2. Bake for 25 minutes. An adult places the loaf pan in the oven on the middle rack. Bake for 25 minutes. The bread is done when the top is golden brown and it sounds hollow when you tap it with your knuckle. If you have a thermometer, the inside should read 190-200°F (88-93°C).
3. Cool before slicing (this is hard, but trust me). An adult removes the bread from the oven. Let it cool in the pan for 5 minutes, then turn it out onto a cooling rack or clean towel. Wait at least 15 more minutes before cutting. If you slice hot bread, the inside will be gummy. Patience makes better bread.

Tip: The hollow tap test works like this: flip the bread out of the pan and knock on the bottom with your knuckles. If it sounds hollow like a drum, it's done. If it sounds like a thud, put it back in (without the pan) for another 5 minutes.

Shape Your Loaf

Two options depending on what equipment you have.

Loaf Pan (Sandwich Bread) (recommended)

Makes a classic rectangular loaf perfect for sandwiches and toast.

1. Pat into a rectangle. Pat the dough into a flat rectangle roughly the width of your loaf pan.
2. Roll it up tight. Starting from one short end, roll the dough up tightly like a sleeping bag. Keep tension as you roll.
3. Seal and place. Pinch the seam closed. Tuck the ends under. Place seam-side down in a greased loaf pan.

Free-Form Round (No Pan Needed)

No loaf pan? Shape it into a ball and bake it on a sheet. You'll get a rustic round loaf.

1. Shape into a ball. Pull the edges of the dough toward the center, rotate, and repeat until you have a tight ball with a smooth top.
2. Place on parchment. Set the ball seam-side down on a parchment-lined baking sheet.
3. Slash the top (optional). Use a sharp knife to cut an X or a single line across the top. This controls how the bread expands in the oven and looks professional.

Proof test: Poke the side of the risen dough with a floured finger. If it springs back slowly and leaves a small dent, it's ready. If it snaps back fast, give it more time.

Bake

A moderate oven temperature gives you a soft crust and fluffy interior.

Oven: 190°C / 375°F. Internal temperature when done: 90°C / 195°F.

Loaf Pan in Standard Oven (recommended)

The classic method. Produces a sandwich-style loaf.

Equipment: Greased 8½ x 4½ inch loaf pan

1. Preheat. Preheat oven to 375°F (190°C) for at least 15 minutes.
2. Bake. Place loaf pan on middle rack. Bake 25 minutes until golden brown on top.
3. Check doneness. Tap the bottom of the bread. If it sounds hollow, it's done. Internal temp should be 190-200°F (88-93°C).
4. Cool. Cool in pan 5 minutes, then turn out onto a rack. Wait at least 15 minutes before slicing.

Free-Form on Baking Sheet

For a rustic round loaf when you don't have a loaf pan.

Equipment: Parchment-lined baking sheet

1. Preheat. Preheat oven to 375°F (190°C) for at least 15 minutes.
2. Bake. Place baking sheet on middle rack. Bake 25-30 minutes until deep golden brown.
3. Cool. Cool on the baking sheet for 5 minutes, then transfer to a rack.

Note: An adult must handle all oven tasks. No exceptions.

Storage

• Room temperature: 3-4 days in a bread bag or wrapped in a clean towel. Best on day one and two.
• Frozen: Slice first, then freeze in a zip-top bag for up to 2 months. Toast slices straight from the freezer.
• Refresh: If the crust goes soft, toast individual slices or warm the whole loaf in a 350°F (175°C) oven for 10 minutes.

Frequently Asked Questions

What kind of bag should I use?

A heavy-duty gallon-size freezer bag. Regular sandwich bags are too thin and will split when you start squishing. Freezer bags are thicker and can handle the pressure. If you're buying specifically for this, look for the ones labeled "freezer" on the box.

Can I use bread flour instead of all-purpose?

Yes. Bread flour has more protein, which means more gluten and a slightly chewier loaf. Both work great. Use whatever you have.

My bag ripped. What do I do?

Transfer everything to a bowl and mix by hand with a fork, then knead on the counter. You haven't lost anything. The bag is just a mixing tool. You can finish this bread without it.

The dough is still super sticky after squishing. Did I mess up?

Probably not. Open the bag and add 1-2 tablespoons of flour. Seal and squish more. Flour absorbs water at different rates depending on humidity, brand, and how you measured. A little adjustment is normal.

Can we make this without a loaf pan?

Absolutely. Shape the dough into a ball and bake it on a parchment-lined baking sheet. You'll get a rustic round loaf instead of a sandwich shape. Same bread, different look.

How many kids can make this at the same time?

Each kid gets their own bag, so as many as you have counter space and bags for. One adult can supervise 8-10 kids during the bag mixing and kneading phases. The oven work is always adult-only.

Can I add things to the bread?

Yes. After the bag squishing is done and you're kneading on the table, you can fold in mix-ins like shredded cheese, dried herbs (rosemary is great), cinnamon and raisins, or even chocolate chips. About ¼ cup to ½ cup of mix-ins per loaf.
