The Method for Baileys Irish Cream Cheesecake Bars

Step 1: Prepare the Crust
Start by preheating your oven to 325°F (160°C). In a food processor, crush the Oreo cookies until they resemble fine crumbs. Transfer the crumbs to a mixing bowl and pour in the melted butter. Stir until the mixture resembles wet sand. Press this mixture evenly into the bottom of a greased 9×13-inch baking pan to form the crust. Bake for 10 minutes, then remove from the oven and allow to cool slightly.
Step 2: Make the Cheesecake Filling
In a large mixing bowl, combine the room temperature cream cheese and granulated sugar. Use an electric mixer on medium speed until smooth and creamy. Next, add the sour cream, vanilla extract, and espresso powder, mixing until completely incorporated.
Step 3: Add the Eggs and Baileys
With the mixer on low speed, add the eggs and egg yolks one at a time, mixing just until combined. Finally, pour in the Baileys Irish Cream and all-purpose flour. Mix until just combined, taking care not to overmix.
Step 4: Bake the Cheesecake Bars
Pour the cheesecake filling over the pre-baked crust, smoothing the top with a spatula. Bake in the preheated oven for 40-45 minutes, or until the edges are set but the center has a slight jiggle. Turn off the oven and crack the door open, allowing the cheesecake to cool gradually for about an hour.
Step 5: Prepare the Ganache
While the cheesecake cools, make the ganache. In a small saucepan, heat the heavy cream over medium heat until it begins to simmer. Remove from heat and add the chopped semi-sweet chocolate. Let it sit for about 2 minutes, then whisk until smooth. Stir in the additional 3 tablespoons of Baileys Irish Cream.
Step 6: Assemble and Chill
Once the cheesecake has cooled to room temperature, pour the ganache over the top, spreading it evenly. Refrigerate for at least 4 hours, or overnight for best results, before slicing into bars.
Make It Fit Your Plan

- Gluten-Free Option: Substitute gluten-free cookies for the Oreo crust.
- Dairy-Free Option: Use dairy-free cream cheese and coconut cream in place of heavy cream.
- Less Sweet Option: Reduce the amount of sugar in the filling to suit your taste.
- Alcohol-Free Option: Replace Baileys with a coffee-flavored syrup or an alcohol-free cream liqueur.
Chef’s Notes
- Make sure all your ingredients are at room temperature for the best mixing results.
- Don’t skip the espresso powder; it really enhances the chocolate flavor!
- For clean cuts, use a sharp knife and wipe it between cuts.
- If you prefer a firmer texture, bake the cheesecake a few minutes longer, but be careful not to overbake.
Make-Ahead & Storage
These Baileys Irish Cream Cheesecake Bars can be made a day in advance, making them perfect for parties or gatherings. Once fully chilled, store them in the refrigerator in an airtight container for up to 5 days. If you want to freeze them, wrap individual bars in plastic wrap and then in aluminum foil. They can be frozen for up to 2 months. Just thaw in the refrigerator before serving!
Ask the Chef
Can I use a different type of cookie for the crust?
Absolutely! You can use any type of chocolate sandwich cookie, or even graham crackers for a different flavor profile. Just be sure to adjust the amount of butter accordingly.
What should I do if my cheesecake cracks while baking?
Cracking can happen if the cheesecake bakes too long or too quickly. To minimize cracking, make sure not to overmix the batter and consider baking in a water bath for a gentler cooking environment.
Can I make these cheesecake bars without Baileys?
Yes, you can substitute Baileys with an alcohol-free coffee-flavored syrup or simply omit it for a classic cheesecake flavor. You can also experiment with other flavored liqueurs.
How do I know when the cheesecake is done baking?
The cheesecake is done when the edges are set and the center has a slight jiggle. It will continue to firm up as it cools.
