Instructions

1. Grab a large bowl and thoroughly combine 3 cups flour, ½ teaspoon baking powder, and ¼ teaspoon salt using a whisk. Set this dry mixture aside for later.

3. Gradually add 2 ½ cups sugar to the butter, beating until the mixture becomes fluffy and light.
4. Incorporate 6 large eggs one at a time, mixing gently after each addition until just blended.

10. Transfer the entire batter into the prepared bundt pan, spreading evenly.
11. Place the pan in a preheated oven at 325°F and bake for 1 hour and 15-30 minutes.

• Room temperature eggs and butter blend more smoothly and create a more consistent cake batter with better volume.
• Grease the bundt pan thoroughly with butter and flour to prevent sticking and ensure a clean cake release.
