This version has been calibrated to fit tightly into a 20 x 20 cm square pan and yield 25 pieces measuring approximately 4 x 4 cm. The doneness of the brigadeiro, the amount of biscuit and the resting time are the three factors that most influence a clean cut.
Ingredients
• 2 cans or boxes of condensed milk (790 g in total)
• 60 g of chocolate powder 50% cocoa
• 35 g of unsalted butter, 30 g for the brigadeiro and 5 g for greasing
• 300 g of cornstarch biscuits
• 40 g of caster sugar to finish
Preparation method
1. Prepare the pan and cookies
Line a 20 x 20 cm square pan with baking paper, leaving flaps on the sides to make it easier to remove, and lightly grease the paper with 5 g of butter. Break the cookies with your hands into pieces measuring approximately 2 to 3 cm. Avoid crushing: larger pieces help to form the internal design and reduce excess bran.
2. Cook the brigadeiro until firm.
Place the condensed milk, chocolate powder and 30 g of butter in a thick-bottomed pan. Mix before turning on the heat and cook over low to medium heat, stirring constantly and scraping the bottom and sides. In general, the point arrives in 12 to 15 minutes after the mixture heats up well. The brigadeiro should thicken a lot, come away from the bottom and move as a single mass when the pan is tilted.
3. Confirm the point before taking it off the heat
Run the spatula across the bottom of the pan. The open path should remain visible for about 2 seconds before closing. When lifting the spatula, the mixture should fall in thick blocks, not in a continuous stream. If it still runs quickly, cook for another 1 to 2 minutes, stirring constantly, and test again.
4. Incorporate the biscuit
Turn off the heat and wait about 2 minutes, just for the boiling to stop. Add the broken biscuits and mix with firm, short movements, until all the pieces are coated in the brigadeiro. Stop once it's smooth to avoid breaking the cookies too much.
5. Model with uniform thickness
Immediately transfer to the prepared pan. Distribute the dough to the corners and press down with a lightly greased spatula or another sheet of baking paper on top. Try to maintain a thickness of approximately 2 cm and a level surface. Compact enough to remove air pockets without crushing the cookies.
6. Let it set
Wait about 20 minutes, until the mold stops releasing intense steam, and refrigerate for at least 2 hours and 40 minutes. Total rest is around 3 hours. For even more precise cutting, the straw can remain refrigerated for longer before portioning.
7. Cut into 25 squares
Remove the plate from the pan by the paper flaps and place it on a cutting board. With a ruler, mark 4 cm intervals on all four edges. Use a long, sharp knife, heated quickly in hot water and dried very well. Make five stripes in one direction and five in the other, cleaning and drying the blade after each cut. Roll the squares in sugar or sprinkle a thin layer on top and sides.
Right spot / how to know it’s ready
Over the heat, the brigadeiro is ready for cutting when it leaves the bottom of the pan visible for about 2 seconds after passing the spatula, it comes off easily and falls into thick portions. Once chilled, the plate must be firm to the touch, lift entirely by the paper and keep the edges defined when cut. The knife should come out with little dough adhering.
If the plate remains very soft after resting, the brigadeiro was probably removed from the heat too soon. More time in the fridge can help it firm up, but it won't completely correct a spot that's much lower than necessary.
Tips for the recipe to work out
Use a thick-bottomed pan and moderate heat. High heat can concentrate the bottom before the entire dough reaches the point, increasing the risk of burning and leaving the texture uneven.
Keep the pan at 20 x 20 cm for this quantity. A larger shape makes the board thin and more fragile; a smaller pan produces very tall pieces and requires more pressure to level.
Break the biscuit, but don't turn it into crumbs. Excess bran absorbs moisture faster and leaves the straw denser and less marked by visible lumps.
For straight cuts, use a heated and completely dry knife. Cleaning the blade between cuts avoids dragging chocolate and crumbs to the next edges.
Do not add heavy cream to this version if the main objective is firm cutting. It makes the brigadeiro softer and requires a new calibration of point and biscuit proportion.
Substitutions and variations
Butter can be replaced with the same amount of culinary margarine. The flavor changes slightly, but the function in the dough is similar.
Biscoito Maria can be substituted for cornstarch biscuits for the same weight. As thickness and absorption vary between brands, add the last 30 g little by little if you notice that the mixture is already too biscuity.
If using 100% cocoa powder in place of 50% chocolate powder, start with 35 to 40 g. The result is less sweet and more intense, and the dough may thicken a little faster; follow the visual point instead of relying solely on time.
Regular milk does not directly replace condensed milk in this formula, as it alters the sugar, solids and structure of the brigadeiro.
How to store
Once cooled and cut, store the squares in a clean, well-closed container, preferably with baking paper between layers. For safe storage, keep refrigerated at 4°C or below and consume within 5 days. Remove from the refrigerator a few minutes before serving if you prefer a less firm texture.
At room temperature, use only for the serving period and avoid leaving the candy exposed to heat. To store overnight, prefer the refrigerator.
It can be frozen in a tightly closed container, with the layers separated by wax paper, for around 30 days. Thaw in the refrigerator. The cookie tends to get a little softer after freezing.
How to serve / side dishes
Serve the squares at a cool temperature, when they hold their shape better and are still soft to the bite. For parties or individual sales, paper molds help protect the sides and maintain the sugar finish.
Common mistakes
Why has the Italian straw become soft and doesn't cut properly?
The most common cause is undercooked brigadeiro. The mixture needs to come off the bottom and slowly close the path opened by the spatula before receiving the biscuit. A pan that is too large also makes the board thin and more difficult to handle.
Why did the straw become hard or brittle?
The brigadeiro may have cooked longer than necessary or the biscuit proportion may have been too high. Remove from the heat as soon as signs of dots appear and weigh the biscuit to maintain the proportion.
Why were the cuts blurry?
The plate may be a little cold, or the knife may be carrying dough from one cut to the next. Refrigerate for longer and use a long, warm, dry and clean blade with each pass.
Why are there barely any cookie pieces?
This usually happens when the cookie is crushed too much or when the mixture is stirred for too long after it goes in. Break into 2 to 3 cm pieces and mix just until combined.
Frequently asked questions
Does it need to be chilled to cut?
For this version, yes. Cooling completes the firmness necessary to remove the entire plate from the mold and mark regular squares without deforming the edges.
