Preheat the Oven and Prepare the Pan:

• Preheat your oven to 350°F (175°C).
• Grease a 10-cup Bundt pan and lightly dust with flour.

Make the Vanilla Batter:

• In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
• In a large bowl, beat the softened butter and sugar until light and fluffy.
• Add the eggs, one at a time, beating well after each addition. Mix in the vanilla extract.
• Gradually add the flour mixture and milk in alternating batches, beginning and ending with the flour. Mix until smooth.

Make the Chocolate Batter:

• Repeat the same steps as the vanilla batter, but whisk the cocoa powder into the flour mixture first.

Create the Zebra Pattern:

• Start by pouring 2-3 tablespoons of vanilla batter into the center of the Bundt pan.
• Pour 2-3 tablespoons of chocolate batter directly on top of the vanilla batter.
• Continue alternating batters, pouring each directly into the center of the previous layer, until all the batter is used. The layers will spread naturally to create the zebra pattern.

Bake the Cake:

• Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
• Let the cake cool in the pan for 10 minutes, then invert onto a wire rack to cool completely.

Make the Glaze:

• In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency with more milk if needed.
• Drizzle the glaze over the cooled cake. For a marbled effect, drizzle melted chocolate or cocoa glaze on top.

Serve:

• Slice and enjoy the beautiful zebra pattern with every bite!
