Identify what you need most: a true center hole, a bundt-like exterior pattern, or just a sliceable cake with similar bake behavior.
Choose the closest match: tube pan for best rise/release; springform with a parchment collar for a ring look; loaf/two rounds for “Bundt vibe” when shape matters less.
Grease based on the pan’s surface: deeper grease + flour (or cocoa) for light-colored pans; use a parchment collar/wedge where batter could escape.
Adjust bake time: start checking early (about 5–10 minutes sooner than your Bundt-pan recipe) and use a toothpick/instant-read test.
Cool correctly: invert/release only after the pan cools enough to let the cake set (typically 10–20 minutes), then continue cooling on a rack.
