Portuguese Sweet Bread Loaf
This Portuguese Sweet Bread Loaf recipe is makes a soft, light, white bread for sandwiches. It’s a sweet, enriched bread with a punch of flavor from citrus zest and vanilla extract.
This sweet sandwich bread might not stand out in a steak sandwich, but it does great with turkey and cheese, cream cheese and jelly, and, of course, peanut butter and jelly. And there’s no better use for this bread when stale than my French toast waffles!

Ingredients
This Portuguese sweet bread recipe is made with a sweetened, enriched dough. It also has lemon and orange zest and vanilla for flavor.
Enriched dough has butter, eggs, or milk added to the flour, yeast, and salt. Other examples of enriched breads are my chocolate chip brioche, raisin challah, and Japanese milk bread. Note that this is different than enriched flour, which has added vitamins and minerals.

Recipe tips and tricks
Step by step
Step 1: Make the sponge for this Portuguese sweet bread.
Step 2: Add all the other ingredients on top. Cover the mixing bowl with plastic wrap and let it rise in a warm place.
Tip from the wise quacker: The best temperature to proof bread is the high 70s. If your kitchen is cool, create a warm place by either 1) turning on your oven (use the proofing function if it has one) and turn it off when it reaches 80 degrees or 2) heat a microwave-safe cup of water in your microwave for a minute or two. Remove the water and quickly add your bread dough.
The sponge will start to bubble through after an hour our two.
Step 3: Once the sponge is actively bubbling through, mix the dough, and shape it into a boule to let rise in the greased mixing bowl.
It should double in size or more in about two hours.
Step 4: Divide the boule into two equal pieces and shape them into loaves. Put loaf in buttered 9 inch by 5 inch loaf pans or, per the original, into boules in two oiled 9 inch pie or cake pans.
Cover with plastic wrap and again proof until doubled in size. As bread rises, they should reach about an inch or so above the loaf pan.
Step 5: Preheat the oven to 350°F and bake for 50 to 60 min until the internal temperature reaches 190°F. Check for burning after 30 minutes and cover loosely with foil if the top looks like it is getting too brown.
Step 6: Cool for at least one hour before cutting!
Lessons learned
Please don’t make the same mistake I made of thinking that a recipe with three and a half cups of flour makes a single sandwich loaf of this sweet Portuguese bread. That thinking resulted in the below.
And, yes, that is my baking ruler. A friend gave it to me years ago because I’m an infectious disease specialist who focuses on HIV and sexually transmitted infections. For those of you asking where to get one like this, she doesn’t remember where she bought it.
Storage
Store bread at room temperature in a plastic bag or airtight container for a few days. You can also slice the loaf and freeze slices in a freezer bag with all of the air removed. Never store bread in the refrigerator, or it will dry out.
Recipe FAQs
The Hawaiian and Portguese sweet breads are definitely related. Sweet bread was brought to Hawaii by Portuguese immigrants in the 1800s.
Sweetbreads are a totally different thing – the thymus and sometimes the pancreas. It’s usually from a young animal because, I’m guessing, the thymus (an organ of the immune system) undergoes involution and decreases in size in all mammals, just like I learned about in medical school.
It can be. And if you can look online you’ll see links to a springtime pagan festival that became the basis for Easter. But that’s too much for me to get into here.
