Preparation: Begin by preheating your oven to 350°F and generously greasing two round 8-inch cake pans.
Creaming Butter and Sugar: In a large mixing bowl, beat the softened butter and sugar until the mixture reaches a light and fluffy consistency.
Incorporating Eggs and Flavor: Add the eggs one at a time, ensuring thorough incorporation after each addition. Introduce vanilla extract, rum, and the zest of one orange and one lemon for a burst of citrus flavor.
Combining Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this dry mixture to the butter and egg concoction, ensuring a well-balanced and homogeneous batter.
Optional Food Coloring: If you desire a vibrant touch, now is the time to introduce optional food coloring. Experiment with different hues, adding a playful element to your cake.
Baking: Divide the batter evenly into the prepared cake pans. Bake in the preheated oven for 50 minutes to an hour. Check for doneness by inserting a toothpick into the center; if it comes out clean, your cakes are ready.
Cooling: Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack. Ensuring proper cooling prevents sticking and ensures an even texture.
Serving: Once fully cooled, unleash your creativity in serving. Dust with powdered sugar for a simple touch or top with fresh fruits, whipped cream, or a decadent fruit compote or sauce.
Enjoy: Slice the Guyanese sponge cake into wedges and savor the delightful combination of rich tradition and heavenly flavor.
