Ingredients You’ll Need

1/2 cup (90g) white chocolate chips: These add a decadent sweetness to the filling; Ghirardelli brand provides a rich flavor. If you prefer dark chocolate, feel free to substitute!
4 oz full-fat cream cheese, softened: This creates the creamy filling that brings everything together beautifully. Use low-fat cream cheese for a lighter version.
1/4 cup (56g) unsalted butter, softened: Adds richness to the filling; make sure it’s at room temperature for easy mixing.
Pinch of kosher salt: Enhances the sweetness of the filling and balances flavors.
1 cup (110g) powdered sugar: Gives the filling its sweet touch; sift it beforehand for a smoother texture.
1/4 cup (56g) unsalted butter, melted: Melted butter makes the cookie dough easy to spread; let it cool slightly before use.
1/4 cup (56g) vegetable oil: Keeps the bars moist; can be replaced with coconut oil for a hint of tropical flavor.
3/4 cup (150g) packed light brown sugar: Its moisture adds depth and chewiness to the oatmeal bars.
1/4 cup (50g) granulated sugar: Gives just the right amount of sweetness in combination with the brown sugar.
1 tbsp unsulfured molasses: This ingredient adds a rich, deep flavor to the bars; you could use honey in a pinch.
1 large egg: Binds the ingredients while adding moisture; for a vegan option, try using a flax egg.
2 tsp vanilla extract: Pure flavor enhances the richness of the cream and cookies.
1 tsp cinnamon: Infuses warmth and spice into the oatmeal cookies.
1/2 tsp baking powder: Helps the bars rise a bit for a light and fluffy texture.
1/2 tsp kosher salt: Balances the flavors in the cookie dough.
1 cup (100g) quick oats: They give that signature chewy texture; avoid instant oats as they can turn mushy.
1/2 cup (120g) whole milk: Adds creaminess; non-dairy alternatives like almond or oat milk work great too.
1 1/2 cups (192g) all-purpose flour or 1-to-1 gluten-free baking flour: Flour holds everything together; if using gluten-free, ensure it contains xanthan gum.

How to Make Oatmeal Cream Pie Bars

Melt the White Chocolate: In a microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring frequently, until smooth. This should only take about a minute; be cautious not to overheat.
Make the Cream Filling: In a medium bowl, combine 4 oz of softened cream cheese, 1/4 cup unsalted butter, and a pinch of kosher salt. Mix until smooth, then stir in 1 cup powdered sugar and melted white chocolate until no lumps remain.
Prepare the Pan: Line the bottom of a 9” springform pan with parchment paper and reassemble the ring over it. Spread the cream filling evenly in the pan, leaving a ¼” border. This will ensure even baking. Transfer it to the freezer while you prepare the cookie dough.
Preheat the Oven: Set your oven to 350°F (175°C) while you prepare the oatmeal cookie batter.
Combine the Dough Ingredients: In a large bowl, whisk together 1/4 cup melted butter, 1/4 cup vegetable oil, 3/4 cup light brown sugar, and 1/4 cup granulated sugar until well mixed. Add the egg and 2 teaspoons vanilla extract, mixing thoroughly.
Incorporate Dry Ingredients: Mix in 1 teaspoon cinnamon, 1/2 teaspoon baking powder, and 1/2 teaspoon kosher salt until incorporated. Add in 1 cup quick oats, followed by 1/2 cup whole milk, and whisk until smooth. Lastly, fold in 1 1/2 cups of all-purpose flour gradually until the mixture is well combined.
Layer the Dough and Cream: Remove the cream filling from the freezer and peel back the parchment paper. In the greased pan, spread half of the dough into an even layer on the bottom. Place the cream filling on top, gently pressing it to secure, then spread the remaining dough evenly over it.
Bake: Bake for 30-35 minutes, or until the edges are golden and puffed slightly. The center may still seem a little jiggly; this is a sign of the creamy filling inside.
Cool: Allow the bars to cool in the pan for about 30 minutes. Once cooled, carefully remove the ring of the springform pan and chill the bars in the fridge for about 2 hours, or until fully set.
Slice and Serve: After chilling, slice into bars and enjoy your delectable creation!

Storing & Reheating

Store the Oatmeal Cream Pie Bars at room temperature for up to two days, ensuring they are well covered to retain freshness. If you need to keep them longer, they can be refrigerated in an airtight container for up to a week. For long-term storage, freeze the bars, ensuring they are wrapped tightly to avoid freezer burn, and they can last up to three months. When ready to enjoy after freezing, let them thaw in the fridge overnight or at room temperature for a few hours. The texture may change slightly after freezing, but bringing them to room temperature can help refresh their appeal.

Chef’s Helpful Tips

Ensure your cream cheese is softened before mixing. Cold cream cheese can lead to lumpy filling.
Avoid overbaking—the bars are done when the edges are golden and the center jiggles a little. They will set further as they cool.
For a richer flavor, consider adding 1/4 teaspoon of nutmeg along with the cinnamon.
If you’re short on time, you can even pre-make the dough a day in advance; just store it in the fridge to chill.
Use parchment to line the pan. It prevents sticking and helps with easy removal for pretty presentation.

There’s something uniquely comforting about homemade treats, and Oatmeal Cream Pie Bars offer that special bit of nostalgia we all crave. Whether you’re sharing them at a gathering or savoring them alone, the blend of creamy and chewy textures will create a lasting impression. Don’t hesitate to experiment with the filling or add your favorite spices—after all, it’s all about making it your own. I hope you enjoy every luscious bite!

Recipe FAQs

Can I use different types of oats for this recipe?

Absolutely! While quick oats are used for their soft texture, old-fashioned oats can be a great substitute. They will give the bars a slightly different texture, but they’ll still taste delicious.

How can I make these oatmeal cream pie bars gluten-free?

Great question! Simply swap the all-purpose flour for a 1-to-1 gluten-free baking flour mix. Just be sure to check that your oats are certified gluten-free as well!

Can I make these bars ahead of time?

Yes! These bars can be made a day ahead and stored in the fridge. This not only saves you time but also allows the flavors to meld beautifully.

What’s the best way to cut the bars?

To get clean cuts, use a sharp, non-serrated knife dipped in warm water. Wipe the knife clean between cuts for the best result. Enjoy your perfectly sliced oatmeal cream pie bars!
