Directions

Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, baking soda, salt, cinnamon, and nutmeg.
In a large mixing bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract.
Gradually mix in the dry ingredients until just combined. Fold in rolled oats.
Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing about 2 inches apart. Slightly flatten each cookie.
Bake for 10–12 minutes, or until the edges are golden and the centers are set. Let cookies cool completely on a wire rack.
Match cookies in pairs of similar size. Soften the cinnamon ice cream slightly, then scoop and spread onto one cookie.
Top with the second cookie and press gently. Smooth the sides and place on a baking sheet.
Freeze sandwiches for at least 2 hours before serving.

Storage/Reheating

FAQs

Can I use quick oats instead of rolled oats?

Rolled oats give a better texture, but quick oats can be used in a pinch. Avoid using instant oats.

What if I can’t find cinnamon ice cream?

You can mix ground cinnamon into vanilla ice cream to mimic the flavor. Start with ½ to 1 teaspoon per pint.

How do I keep the cookies soft after freezing?

Don’t overbake the cookies. Slightly underbaked cookies stay softer in the freezer.

Can I make the cookies ahead of time?

Yes, bake the cookies up to 2 days in advance and store them in an airtight container before assembling.

Can I use store-bought oatmeal cookies?

Yes, but make sure they’re soft and thick enough to hold the ice cream without breaking.

What’s the best way to assemble the sandwiches?

Soften the ice cream slightly, spread evenly, and freeze immediately after assembly to keep them firm.

Can I use homemade cinnamon ice cream?

Absolutely. Homemade ice cream will add a rich, fresh flavor if you have an ice cream maker.

Can I add mix-ins to the ice cream?

Yes! Try chopped walnuts, raisins, or swirls of caramel for added texture and flavor.

How long do these need to freeze before serving?

At least 2 hours, but overnight freezing will give the best consistency.

Can I use a different spice in the cookies?

Yes, try adding ground ginger or cloves for a more complex spiced profile.
