Vanilla Extract: Adding vanilla extract is optional. If you have real vanilla extract available, feel free to use it as it adds a subtle creamy vanilla flavor. However, if you don’t have any on hand, it’s not necessary to go out and buy it. Vanilla extract can be quite pricey, so if you bake frequently, consider purchasing a large bottle from stores like Costco, where it’s often more affordable than smaller bottles.
Sifting Flour: Avoid adding all the flour at once to prevent lumps and ensure even incorporation. To sift, gently tap the edge of a fine mesh strainer over the bowl to create a light dusting of flour on top. Whisk this in gently, then repeat the process, adding flour in small amounts until all is incorporated.
Preparing the Loaf Pan: Buttering the loaf pan first helps the parchment paper stick better inside, making it easier to pour the cheesecake batter without it slipping or folding.
Parchment Paper: Be sure to use parchment paper, not wax paper, as they are very different. Wax paper will melt in the oven, so only parchment paper is safe for baking.
Baking Time: Don’t worry if the top of your cheesecake becomes very dark. The top will caramelize, but the inside remains light and creamy. If the top isn’t dark enough, the center may not set properly.
Loaf Pan Size: Loaf pans vary in size—some that are labeled 9x5 inches might actually be larger or have different heights. If your batter doesn’t fit entirely, fill the pan leaving about a ½-inch space at the top. Keep a close eye on the baking time and remove the cheesecake when the edges are very dark brown and the center is slightly lighter.
Overflow: If your loaf pan is filled close to the top, place it on a baking sheet to catch any possible overflow during baking. While I’ve never experienced overflow despite making dozens of Basque cheesecakes, it can be a helpful precaution depending on your pan’s exact size.
