Ingredients You’ll Need

1/2 cup white chocolate chips: For a deliciously sweet layer; Ghirardelli is a solid choice. You can substitute with semi-sweet if preferred.
4 oz full-fat cream cheese, softened: This adds creaminess to the filling. Light cream cheese can work, but the flavor and texture may vary slightly.
1/4 cup unsalted butter, softened: It builds the tasty base for your filling. Make sure it’s at room temperature for easy mixing.
Pinch of kosher salt: Enhances flavor, balancing sweetness wonderfully.
1 cup powdered sugar: For sweetness in the cream filling; sifted helps avoid clumps.
1/4 cup unsalted butter, melted: Serves as a component for the cookie dough; melted butter helps create a denser texture.
1/4 cup vegetable oil: Keeps the bars moist and chewy. You can substitute with canola oil if preferred.
3/4 cup packed light brown sugar: Adds depth and that signature molasses flavor. Brown sugar helps keep the bars soft.
1/4 cup granulated sugar: Just a little, to sweeten up your cookie dough.
1 tbsp unsulphured molasses: Boosts flavor and adds moisture; maple syrup can be a substitute in a pinch.
1 large egg: Binds the dough together; make sure it’s fresh for the best results.
2 tsp vanilla extract: For that warm, comforting flavor; use high-quality vanilla for the best taste.
1 tsp cinnamon: Adds warm spice notes; feel free to adjust based on your love for cinnamon.
1/2 tsp baking powder: Helps the bars rise slightly for a wonderful texture.
1/2 tsp kosher salt: Balances the flavors and enhances sweetness.
1 cup quick oats: Create a chewy texture. Old-fashioned oats could also work, just expect a bit more chew.
1/2 cup whole milk: Adds moisture to your dough; if dairy-free, almond or oat milk can be used.
1 1/2 cups all-purpose flour or 1-to-1 gluten-free baking flour: Provides structure; ensure it’s leveled for accuracy.

How to Make Oatmeal Cream Pie Bars

Melt the White Chocolate: Start by melting 1/2 cup of white chocolate chips in the microwave. Do this in 30-second intervals for about a minute total, stirring frequently until smooth. Set it aside to cool slightly.
Prepare the Filling: In a medium bowl, combine 4 oz of softened full-fat cream cheese, 1/4 cup of softened unsalted butter, and a pinch of kosher salt. Use a mixer or a fork to mix until smooth and creamy. Gradually add in 1 cup of powdered sugar and the melted white chocolate, mixing until you have a lump-free filling.
Set Up the Springform Pan: Remove the ring from a 9” springform pan and place a sheet of parchment paper on the bottom plate, ensuring it’s slightly larger than the plate. Replace the ring, sealing it tightly, and then spread the cream filling evenly across the bottom, leaving a 1/4-inch border. Place the pan in the freezer to firm up the filling.
Make the Dough: Preheat your oven to 350°F. In a large bowl, whisk together 1/4 cup of melted unsalted butter, 1/4 cup vegetable oil, 3/4 cup packed light brown sugar, and 1/4 cup granulated sugar until well combined. Mix in 1 tbsp unsulphured molasses, 1 large egg, and 2 tsp vanilla extract, followed by 1 tsp cinnamon, 1/2 tsp baking powder, and 1/2 tsp kosher salt.
Incorporate the Oats and Flour: Stir in 1 cup of quick oats, mixing until distributed evenly. Then add in 1/2 cup of whole milk, creating a thinner batter. Finally, whisk in 1 1/2 cups of flour for a creamy consistency.
Layer the Bars: By now, your cream filling should be firm. Carefully remove it from the freezer. Spray the inside of the same springform pan with non-stick spray and line the bottom with parchment paper again. Spread half of the oatmeal dough into the bottom of the pan, creating an even layer.
Add the Cream Filling: Gently take the frozen cream filling and place it in the middle of the pan, lightly pressing it into place. Spread the remaining cookie dough on top, ensuring it reaches all the edges.
Bake: Place the pan in the preheated oven and bake for 30 to 35 minutes. You’ll want to look for golden edges, a puffed center, and a dry surface. The middle may still jiggle slightly because of the filling, but that’s perfectly okay— it’ll set once chilled.
Cool and Chill: Allow the bars to cool in the pan for about 30 minutes. After that, remove the ring from the springform pan and chill it in the refrigerator for about two hours, until completely cooled and firm. Then slice and serve!

Storing & Reheating

To keep your Oatmeal Cream Pie Bars fresh, store them at room temperature in an airtight container for up to 24 hours. For longer storage, refrigerate them; they’ll keep well for up to a week. You can also freeze these bars for up to 3 months. Just wrap them tightly in plastic wrap and then in foil. When you’re ready to enjoy them, simply thaw in the fridge overnight. To refresh the texture, give them a quick warm-up in the microwave for a few seconds.

Chef’s Helpful Tips

Make sure your cream cheese is softened at room temperature for the best texture in your filling.
If your dough feels too sticky, refrigerate it for 15–30 minutes before spreading; this can help with handling.
For an extra layer of flavor, consider adding chocolate chips or nuts to the oatmeal dough.
Always check your ingredients for freshness, and using room temperature eggs helps with the mixing process.
If you want to make these bars ahead of time, they stated chill well; just slice them before serving for neat pieces.

Recipe FAQs

Can I make these Oatmeal Cream Pie Bars ahead of time?

Absolutely! These bars are perfect for making ahead of time. You can store them in the fridge for up to a week, or freeze them for up to three months. Just remember to slice them after chilling for neat presentation.

What can I use instead of cream cheese?

If you’re looking for a lighter option or have a dairy allergy, you can substitute the cream cheese with mascarpone cheese or a dairy-free cream cheese alternative. Both will yield delicious results while maintaining that creamy texture.

Why did my bars not set properly?

If your bars didn’t set, it could be due to overbaking or not chilling them long enough. Bake until the edges are golden, and ensure they cool completely before slicing. If it’s too warm when serving, the filling may not hold firm yet.

Can I add mix-ins to the cookie dough?

Certainly! You can stir in chocolate chips, nuts, or even dried fruit to the dough for a fun twist. Just make sure not to overload the dough, as it may affect the baking time and texture.
