It's a fluffy, lightly sweetened dough, topped with ripe bananas and a crumbly topping made of butter, sugar, and flour that turns into an irresistible crust. Put the coffee on, because you'll definitely want a second slice of this one.

German banana cuca with sweet crumble has German roots and is typical of the gaúcho tradition of the German colony in Rio Grande do Sul. It's a sweet coffee cake, perfect for afternoon coffee.

Recipe details

  • Origin: German
  • Region/tradition: Gaúcho (German colony of Rio Grande do Sul)
  • Category: Cake / coffee treat
  • Difficulty: Medium
  • Time: 2h30 (including the dough's rising time)
  • Yield: 12 servings

Ingredients — dough

  • 500 grams (about 4 cups) all-purpose flour
  • 10 grams active dry yeast (or 30 grams fresh yeast)
  • 200 milliliters warm milk
  • 100 grams sugar
  • 80 grams butter at room temperature
  • 2 eggs
  • 1 pinch of salt
  • Lemon zest to taste

Ingredients — banana topping

  • 5 to 6 ripe bananas, sliced
  • 1 tablespoon ground cinnamon
  • 2 tablespoons sugar (to mix with the cinnamon)

Ingredients — sweet crumble

  • 150 grams (about 1¼ cups) all-purpose flour
  • 100 grams sugar
  • 80 grams cold butter

Instructions

  1. Activate the yeast: dissolve it in the warm milk with a tablespoon of sugar and let it rest for about ten minutes, until a foam forms.
  2. In a large bowl, mix the flour, the remaining sugar, the salt, and the lemon zest.
  3. Make a well in the center and add the eggs, the butter, and the yeast-and-milk mixture.
  4. Combine everything with your hands or a spoon until you have a smooth dough.
  5. Knead the dough for about ten minutes, until it becomes smooth, elastic, and no longer sticks to your hands, adding a little more flour if needed.
  6. Cover the bowl with a clean cloth and let the dough rise in a warm spot for about one hour, or until doubled in volume.
  7. While the dough rises, prepare the sweet crumble: in a bowl, mix the flour and sugar and add the cold butter cut into cubes.
  8. Work it with your fingertips until you form a coarse, granular crumble, without overworking it so it doesn't turn into a smooth dough.
  9. Set the crumble aside in the refrigerator until ready to use.
  10. Once the dough has risen, spread it out with your hands in a greased rectangular baking pan, covering the bottom well.
  11. Arrange the banana slices on top and sprinkle with the cinnamon-sugar mixture.
  12. Spread the sweet crumble over the entire surface.
  13. Let it rest for another fifteen minutes.
  14. Bake in a preheated oven at 180°C (350°F) for about 35 to 40 minutes, until the topping is golden and the dough is cooked through.

Tips and variations

  • Use very ripe bananas, as they become sweeter and softer after baking.
  • Swap the banana for apple, guava, or even grapes, all traditional variations in the colonies.
  • Replace part of the all-purpose flour with whole-grain versions.
  • Swap regular milk for plant-based drinks, keeping the same proportion.
  • Add a pinch of anise seed to the dough for extra flavor.
  • Store for up to three days at room temperature, in a sealed container or covered with a cloth.
  • In the refrigerator, it lasts about five days, though it may dry out a bit because of the crumble.
  • Freeze in portions for up to two months; to serve, let it thaw naturally or warm it slightly in the oven to bring back the crunch of the topping.

The history of cuca in the gaúcho colony

Cuca arrived in Brazil with the German immigrants who began settling in Rio Grande do Sul from the nineteenth century onward. The name comes from the German Kuchen, which simply means cake. In the colonies, cuca became an essential part of the café colonial, that hearty afternoon meal with breads, cucas, jams, cold cuts, and cheeses that brings the family together around the table to this day.

Each family keeps its own version of the recipe, passed down from generation to generation, and the sweet crumble is the touch that sets gaúcho cuca apart from other cakes. Making a banana cuca at home is, more than preparing a treat, reviving a heartfelt tradition that spans over a century. So roll up your sleeves, and may this recipe bring a little of the coziness of the southern colonies into your kitchen.
