Instructions

1. 1

   Prepare the pans

   Heat the oven to 200 C (400 F). Butter two 33 x 23 cm (13 x 9 inch) rimmed baking sheets, line them with parchment, and butter the parchment too. Keep extra parchment sheets cut and ready. This cake moves fast once the layers start baking, and a wrinkled or dry sheet grabs the massa and tears it before you've even begun.

   One pan works if that's what you have. You will just pause between layers to cool it, wipe it, reline it, and butter it again. A Tuesday is a Tuesday. The cost is time, not quality.
2. 2

   Melt the goiabada

   Put the diced goiabada and 1/2 cup water in a small heavy saucepan over low heat. Stir and mash until the paste melts into a smooth, glossy spread, about 8 to 10 minutes. It should fall from the spoon like thick honey, not sit there in a lump. Keep it warm on the lowest heat or off the heat with a lid. Warm goiabada spreads in a thin film; cold goiabada drags the cake and rips it.

   Real goiabada cascão gives you fruit texture and deeper guava flavor. Firm guava paste is the honest shortcut. Guava jelly is usually too loose, and guava powder is a packet pretending to be fruit.
3. 3

   Beat butter and sugar

   Put the room-temperature butter and 1 cup sugar in a large bowl. Beat until pale, creamy, and a little fluffy, 4 to 5 minutes, scraping the bowl once or twice. The butter should look smooth, not greasy. This beating traps the small bit of air the thin layers need, so the cake bends instead of turning dense and stubborn.

4. 4

   Add the gemas

   Add the egg yolks, the gemas, one at a time, beating well after each one. The batter should stay creamy and thick. Room-temperature gemas mix into the butter instead of shocking it cold and making it split. If it looks a little curdled, don't panic. I have made uglier bowls behave. The flour will bring it back.

5. 5

   Add flour gently

   Add the sifted flour and salt in two additions, beating on low just until the flour disappears. Stop there. If you keep beating because you want to feel productive, the cake gets tough, and tough cake cracks when rolled. A gente quer massa fina and flexible, not a little plank.

6. 6

   Fold the claras

   In a clean bowl, beat the egg whites, the claras, until they form soft peaks that bend at the tip. Fold one-third into the batter to loosen it, then fold in the rest with a spatula, turning the bowl and lifting from the bottom until no white streaks remain. Soft peaks give the massa enough lift to stay tender without puffing into a thick sheet. Thick sheet, cracked roll. Anota aí.

7. 7

   Spread paper-thin

   Spoon about 1/3 cup batter onto one prepared pan. Spread it with an offset spatula into a very thin, even rectangle, all the way to the corners. You should almost see the parchment through it, with no bare spots. This is the whole lesson: bolo de rolo rolls because the layer is thin enough to bend before it has a chance to argue.

8. 8

   Bake just set

   Bake the first layer on the center rack for 3 to 5 minutes, until the top looks matte and set and the edges are only barely golden. Do not wait for a browned cake smell. Brown means dry here, and dry means cracks. While it bakes, spread the next pan with another 1/3 cup batter so the rhythm is ready.

9. 9

   Fill and start

   Dust a large sheet of parchment or a clean kitchen towel with a little sugar. Turn the warm cake layer onto it, peel off the baking parchment, and spread 2 to 3 tablespoons warm goiabada over the surface in a thin film. Roll from the short end into a tight little log while the cake is warm. The sugar keeps it from sticking, the goiabada glues the spiral, and the warmth lets the butter bend.

   If the first layer tears, press it together and keep rolling. The first one is the center of the spiral, not a public announcement. The next layers cover a lot of sins.

    Build the spiral

    Bake the next layer, turn it onto the sugared parchment, peel, and spread with warm goiabada. Set the first little roll at the short edge of the new layer and roll it forward, wrapping the new sheet around the old one. Keep repeating, wiping crumbs from the pan and re-buttering parchment as needed, until the batter is gone, usually 8 to 10 thin layers. Keep the seam down each time so the roll tightens instead of opening back up.

11. 11

    Rest and slice

    Set the finished roll seam-side down and wrap it snugly in parchment for 20 minutes. This rest lets the goiabada set and the spiral hold its shape. Unwrap, dust lightly with the remaining sugar, trim the ends, and slice with a serrated knife in gentle strokes. If you press straight down like you're angry at it, you'll squash the rings. We worked for those rings.

Chef Tips

• •The massa must be thin enough that you feel slightly nervous spreading it. That's correct. A thick layer looks safer in the pan and betrays you during the roll.
• •Keep the goiabada warm and glossy the whole time. If it thickens, stir in 1 tablespoon water and warm it again. Spreadable filling is kindness to the cake.
• •Do not add baking powder. Bolo de rolo is not trying to rise tall. It is trying to roll thin, tight, and tender.
• •Use butter and eggs at room temperature. Cold eggs make the butter seize, and then you spend the next five minutes wondering what crime you committed. None. You just rushed.
• •Make it a day ahead if you can. The spiral settles, the guava firms, and the slices cut cleaner. Celebration sweets often reward the cook who doesn't leave everything for the last scream.

Advance Preparation

• •Take the butter and eggs out of the fridge 1 hour before baking so they reach room temperature.
• •The goiabada filling can be melted up to 3 days ahead and refrigerated. Rewarm it gently with a splash of water until glossy and spreadable before using.
• •The finished bolo de rolo keeps tightly wrapped for 2 days at room temperature or 5 days in the fridge. Let refrigerated slices come back to room temperature before serving.
• •For longer storage, wrap the cooled roll tightly and freeze for up to 2 months. Thaw still wrapped so the cake doesn't dry out.
