How to Make Portuguese Orange Cake

1. Preheat Your Oven to 350°F (180°C). Grease an 8×8″ baking dish or line it with parchment for easy removal.
2. Cream the Butter and Sugar: In a large bowl, beat softened butter and granulated sugar for about 2 minutes until pale and fluffy.
3. Add the Egg Yolks and Orange Zest/Juice: Mix in yolks one at a time, then add the zest and juice of three large oranges. It might look curdled at this stage — that’s normal.
4. Combine Dry Ingredients: In a separate bowl, whisk together flour and baking powder. Slowly add this to the wet mixture, mixing on low just until combined.
5. Whip the Egg Whites: In another clean bowl, whip the egg whites to stiff peaks using an electric mixer.
6. Fold in the Egg Whites: Gently fold one-third of the whipped whites into the batter to loosen it, then fold in the rest carefully to maintain the fluffiness.
7. Bake: Transfer batter to the prepared dish. Bake for 35–45 minutes, or until the top is springy and a toothpick inserted in the center comes out clean or with a few moist crumbs.
8. Cool and Serve: Let the cake cool in the pan before dusting with confectioners’ sugar. Slice into squares and serve at room temperature.

Expert Tips for the Best Portuguese Orange Cake

• Room Temperature Ingredients: Cold eggs or oranges can cause butter to seize, so let everything sit out beforehand.
• Don’t Overmix: Overworking the flour creates a tough cake. Mix until just combined.
• Use Fresh Oranges: Zest and juice from fresh fruit offer unmatched aroma and taste.
• Check Doneness by Temperature: The cake is done at 190ºF internal temperature.
• Cool Completely Before Slicing: This helps the crumb firm up for clean slices.

Serving Suggestions and Flavor Variations

• Whipped Cream or Mascarpone: A rich contrast to the citrusy bite
• Vanilla Ice Cream: Ideal for a warm-cold texture combo
• Dust of Confectioners’ Sugar: A simple, elegant finish
• Fluffy Vanilla Frosting: For a dessert-worthy upgrade
• Orange Glaze: Mix powdered sugar with a bit of orange juice for a zesty drizzle

For variation, try:

• Chocolate-Orange Version: Fold chocolate chips into the batter before baking
• Layer Cake Style: Divide batter between two 8″ round pans and frost
• Lemon Twist: Use lemon zest and juice for a fresh take on the original
