Preheat oven to 350°F (177°C). Grease a 9x13 inch baking pan thoroughly.

In a large mixing bowl, use an electric mixer to beat eggs with sugar for 5-7 minutes until the mixture becomes thick, pale, and nearly doubles in volume. The batter should form ribbons when lifted from the beaters.

Add softened butter and vanilla extract to the mixture. Mix for an additional 2 minutes until fully integrated.
04 -
Fold in all-purpose flour until just combined. Gently stir in fresh cranberries, ensuring even distribution without overmixing.

Transfer the batter to the prepared pan, spreading evenly. Bake in the preheated oven for 40-50 minutes, or until the surface is lightly golden and a toothpick inserted in the center emerges clean. Begin checking for doneness at 40 minutes.

Remove from the oven and allow the cake to cool completely in the pan. Cut into small pieces, approximately 1x2 inches, for easy serving.
