Directions

1. Preheat oven to 175 °C (350 °F). Line baking sheets with parchment paper.

5. Gradually stir in the dry ingredients until a thick dough forms.
6. Scoop small portions of dough onto the baking sheet, spacing evenly.

FAQs

Can I use quick oats instead of rolled oats?

Quick oats can be used, but the texture will be softer and less chewy.

Can I make the cookies in advance?

Yes, bake the cookies and store them unfilled, then fill closer to serving time for best texture.

What kind of butter should I use for the filling?

Use unsalted butter at room temperature for a creamy, smooth filling.

Can I make these dairy-free?

Yes, use plant-based butter and non-dairy milk in the filling.

How do I keep the cookies soft?

Store in an airtight container and avoid overbaking. Adding a slice of bread to the container can help retain moisture.

Is it necessary to chill the dough?

Chilling isn’t required, but a brief chill (15–30 minutes) helps prevent spreading for thicker cookies.

Can I reduce the sugar?

You can reduce both cookie and filling sugar slightly, but the texture and sweetness balance may change.

What’s the best way to fill the cookies neatly?

Use a piping bag for even, clean application of the cream filling.

Can I make them gluten-free?

Yes, use gluten-free oats and a 1:1 gluten-free flour blend. The cookies may spread slightly more.

Can I flavor the cream filling differently?

Yes, you can flavor it with cocoa powder, espresso, fruit extract, or spices for variations.

Oatmeal cream sandwich cookies bring together classic oatmeal cookie flavor and sweet, creamy indulgence in one nostalgic bite. With their soft texture, spiced notes, and customizable filling, these cookies are ideal for special occasions, gifting, or a satisfying homemade treat any time of year.
