What to remember
- Dense brownies travel better than light, airy ones.
- Freeze before you wrap so the edges stay sharp.
- Weigh the packed box at home to avoid surprise postage.
- Build postage into the price, not on top as an afterthought.
- Ship Monday to Wednesday so the box does not sit over a weekend.
The post is the part most home bakers underprice. If you want to know how to deliver brownies by post without losing money, treat the box, the padding, and the label as part of the product. Your customer is paying for brownies that arrive looking like brownies. For more on the craft side of selling baked goods, see the craft hub.
What kind of brownie survives the post
A fudgy brownie with a tight crumb holds up better than a cakey one. The less air in the bake, the less it crumbles when the box moves. Cut them into squares that fit your box with a little room to spare. If you sell a frosted brownie, keep the frosting thin and let it set fully before you pack. A thick frosting layer can smear even after a freeze, so test one before you offer it for post.
How to pack a brownie box so it arrives whole
Freeze until firm
Chill the brownies in the freezer until they are solid. This keeps them from smearing when you wrap them.
Wrap each brownie
Wrap each square in plastic wrap, then in a layer of foil or parchment. This holds in moisture and keeps the edges neat.
Line the box
Put a layer of bubble wrap or foam at the bottom of a sturdy box. The brownies should not touch the cardboard.
Fill the gaps
Pack the brownies snugly so they cannot slide. Use crumpled paper or more bubble wrap to fill every empty space.
Seal and label
Tape the box shut on all seams. Write the address clearly and add a return address.
What postage and packing really cost
Postage is not the only cost. You also pay for the box, the wrap, the padding, and the tape. Add your time for packing and the trip to the post office. If you use a flat rate box, the price is the same no matter the weight, but you still need to fit the brownies inside. Brevl costs one flat $20 a month and takes 0% of your sales, so your overhead stays the same whether you ship one box or fifty.
The box itself can cost more than the brownies if you buy retail. Look for boxes that fit your brownies with just enough room for padding. A box that is too large needs more filler, which adds weight and cost. Buy your boxes and wrap in bulk when you can. That lowers your cost per box and makes your pricing more predictable.
Work the math in three parts. First, your ingredient cost per box. Second, your packing time at your hourly rate. Third, your fixed overhead divided by the number of boxes you ship. At 20 boxes a month, the $20 Brevl fee is $1 per box. Your margin is the price minus ingredient cost minus labor cost minus that $1. If the margin is too small, raise the price or shrink the box.
At 50 boxes a month, the same $20 fee is 40 cents per box. That lowers the overhead part of your cost. The ingredient and labor costs do not change per box. So the margin grows by 60 cents per box if you keep the same price. That is why volume helps, but only after you cover ingredients and labor.
How to compare flat rate and weight based postage
A flat rate box costs the same no matter how heavy it is. That helps when your brownies are dense and the box is small. A weight based rate changes with the packed weight, so a lighter box and lighter wrap lower the price. Compare both options at your post office with your packed box in hand.
How to choose the right box
The box should be just big enough for your brownies plus one inch of padding on every side. A box that is too small will crush the edges. A box that is too large will let the brownies slide and will cost more to ship. Look for a box with a lid that tucks in, not a flap that pops open. Test one packed box before you buy a case.
How to test a packed box before a big order
Pack one box exactly as you would for a customer. Seal it and shake it gently. If you hear or feel movement, add more filler. Then weigh it and check the postage rate. Do this before you buy a case of boxes or quote a price to a customer.
How to price the post into your brownies
Start with your local price for a dozen brownies. Add the exact postage for the box you packed. Add the cost of the box and padding. Then add your time for packing and shipping. That total is your break even. Add your profit margin on top. If the final price feels high, look at your ingredient cost first. A smaller box or a lighter wrap can bring the postage down.
When to ship and what to check before you commit
Ship early in the week. A box that goes out on Friday may sit in a warehouse over the weekend. Check the weather in the destination city. Extreme heat can melt chocolate, and extreme cold can change the texture. If you are shipping to a hot state in summer, choose a faster service or wait for cooler weather. Always check the tracking number and tell your customer when to expect the box.
What to tell your customer before you ship
Send a message when the box goes out. Give them the tracking number and the expected delivery date. Tell them to open the box as soon as it arrives and to store the brownies in a cool place. If the box is a gift, ask if you should include a note. Clear communication cuts down on refund requests and repeat questions.
How to keep brownies fresh after they arrive
Tell your customer to open the box as soon as it arrives. The brownies should go into a cool, dry place. If they will not eat them within a week, they can freeze the brownies again. A tight wrap before shipping helps them hold moisture.
Mistakes that cost you money on shipped brownies
The biggest mistake is pricing the brownie without the postage. The second is using a box that is too big, which makes the brownies slide and adds weight. The third is shipping late in the week. The fourth is not freezing before wrapping, which leaves smears on the plastic. The fifth is forgetting to add your own time. Each of these eats into the margin you worked for.

Common questions
Can I ship brownies in a regular envelope?
No. Brownies need a box with padding so they do not crush. A padded envelope will not protect the edges. Use a sturdy cardboard box and fill the empty space so nothing moves. The box also gives you room for a label and a return address.
How long do brownies stay fresh in the post?
A well wrapped brownie stays fresh for about a week. The freeze before shipping helps it hold moisture. Tell your customer to keep the box in a cool, dry place. If they want to store them longer, they can freeze the brownies again after they arrive.
Should I charge for shipping or include it in the price?
You can do either, but you must cover the cost. Many home bakers build a flat shipping fee into the listed price so the customer sees one number. If you charge shipping separately, make sure the fee matches the actual postage and packing cost. Do not guess.
What is the cheapest way to ship brownies?
The cheapest way is the smallest box that fits your brownies with padding. A lighter box costs less to ship. Compare the flat rate options with the weight based rate at your post office. Brevl takes 0% of your sales, so your overhead stays low no matter how you ship.
