How to Make Oatmeal Cream Pie Bars

Melt White Chocolate: Start by melting the white chocolate chips in the microwave in 30-second intervals until smooth. This typically takes around 60 seconds total; just be cautious not to overheat it, or it may seize.
Prepare Filling: In a medium bowl, use a mixer or a fork to thoroughly combine cream cheese, softened butter, and a pinch of kosher salt. Next, mix in the powdered sugar until smooth, followed by the melted white chocolate, ensuring there are no lumps. Set aside.
Set Up Springform Pan: Use a 9-inch springform pan, removing the ring to place a sheet of parchment paper on the bottom. Use a piece slightly larger than the plate, then reattach the ring to keep it sealed. Spread the cream filling evenly, leaving a small ¼-inch border. Place the filled pan in the freezer while preparing the cookie dough.
Prepare Dough: Preheat your oven to 350°F (175°C). In a large bowl, whisk together the melted butter, vegetable oil, brown sugar, granulated sugar, and molasses until well incorporated.
Combine Ingredients: Add in the egg and vanilla extract, mixing until blended; then, whisk in the cinnamon, baking powder, and salt. Stir in the quick oats until combined, followed by the whole milk, which gives the batter a nice thin consistency. Finally, whisk in the all-purpose flour until smooth.
Layer the Bars: By now, the cream filling should be frozen solid. Carefully remove it from the springform plate, keeping it on the parchment paper, and set it aside. Reassemble the springform pan, spraying the inside lightly with nonstick spray. Place another piece of parchment on the bottom in the same manner as before.
Build the Layers: Spread half of the oatmeal cookie dough evenly on the bottom of the prepared pan. Take the frozen cream filling and gently place it in the center, lightly pressing down to secure it. Then, spread the remaining dough over the filling all the way to the edges.
Bake: Bake the bars for about 30 to 35 minutes. You’ll know they’re done when the edges are golden and the surface feels dry to the touch. The center will be slightly jiggly due to the melted filling but will firm up as it cools.
Cool and Chill: After baking, let the bars cool in the pan for about 30 minutes before releasing the ring. Chill in the refrigerator for two hours or until completely cooled.
Slice and Serve: Once chilled, slice into bars and enjoy the delightful layers of oatmeal and creamy goodness!

Storing & Reheating

To store your Oatmeal Cream Pie Bars, keep them in an airtight container at room temperature for up to 3 days, or refrigerate them for up to a week. For longer storage, freeze them wrapped tightly in plastic wrap and then in aluminum foil for up to 3 months. When ready to enjoy, thaw them at room temperature or in the refrigerator. If you like them warm, briefly heat them in a microwave for about 10 to 15 seconds. Just be aware that texture and flavor may slightly change upon reheating, but they still taste fantastic!

Chef’s Helpful Tips

Make sure your cream cheese is at room temperature to avoid lumps in the filling.
Use room temperature eggs for better emulsion and texture in your dough.
Gently tap the pan once the bars have baked to see if they are done; the surface should feel dry and not jiggle.
If the bars are too soft upon cooling, it may be helpful to chill them a little longer before cutting.
Consider adding chocolate chips or nuts to the cookie dough for added texture and flavor.
These bars can also be made ahead of time and stored in the refrigerator for a quick dessert option during busy weeks.

Recipe FAQs

Can I use rolled oats instead of quick oats?

Absolutely! While quick oats provide a smoother texture, rolled oats will still work. Just keep in mind that they may alter the consistency slightly, making the bars a bit chewier.

How do I ensure my cream filling is smooth?

Making sure your cream cheese is soft and at room temperature is key. Whip it well with the butter and powdered sugar to achieve that silky smooth texture; no one likes lumps in their filling!

How long can I keep these oatmeal cream pie bars?

These bars can be stored at room temperature for up to 3 days or in the refrigerator for a week. For longer storage, freeze them for up to 3 months. Just remember to let them thaw properly for the best flavor and texture.

Can I make these bars gluten-free?

Yes! Substitute the all-purpose flour with a 1-to-1 gluten-free baking flour. Just be sure to choose a blend that contains xanthan gum for the best results!
