Ingredients
- 4 tablespoons Unsalted butter melted and warm
- 2 tablespoons Avocado oil or vegetable oil
- 1/2 cup Coconut sugar
- 1 Large egg at room temperature
- 1 teaspoon Pure vanilla extract
- 3/4 cup All-purpose flour
- 1 cup Quick-cooking oats
- 1/2 teaspoon Baking soda
- 1/2 teaspoon Ground cinnamon
- 1/4 teaspoon Fine table salt
- 1/2 cup Powdered sugar
- 1 tablespoon Regular milk or plant milk
Instructions
- Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper.
- In a large mixing bowl, stir together the four tablespoons of warm melted butter, two tablespoons of oil, and 1/2 cup of coconut sugar until smooth.
- Whisk in the room temperature large egg and pure vanilla extract for one full minute until the mixture looks glossy and completely cohesive.
- Add the all-purpose flour, quick-cooking oats, baking soda, ground cinnamon, and fine table salt directly into the bowl over the wet base.
- Switch to a sturdy spoon or spatula and fold gently just until the flour disappears and a thick, sticky cookie dough forms.
- Use a standard 1 tablespoon measuring spoon to drop the dough onto your prepared baking sheet, leaving about two inches of space between each cookie.
- Bake at 350°F (175°C) for ten to twelve minutes until the edges are beautifully golden brown but the centers still look slightly soft.
- Remove from the oven and let the cookies cool completely on the baking sheet until they are 100% cold.
- In a small, wide bowl, whisk together the powdered sugar and tablespoon of milk until it forms a very thick, smooth glaze.
- Take a completely cooled cookie and gently press just the bumpy top surface directly down into the thick icing, then lift straight up.
- Place the cookie back onto the parchment paper to let the icing catch only on the high ridges of the oats, creating a shattered ice look.
- Let the iced cookies set undisturbed for ten minutes until the glaze completely hardens before serving.
Notes
The No-Chill Moisture Balance: Utilizing a smart combination of warm melted butter and avocado oil allows you to bypass the refrigerator entirely. Melted butter delivers that rich, unmistakable bakery flavor, while a splash of neutral avocado oil locks in a deep moisture barrier that keeps the centers soft. Folding the quick oats directly into this warm liquid base allows them to hydrate instantly so the dough holds its structure without spreading into puddles.
The Shattered Ice Dipping Trick: To get that iconic, crackly old-school bakery look, make sure your glaze is very thick and your cookies are 100% cold! If the cookies carry any residual warmth, the icing will melt and run off. Hold the bottom of a cold cookie and gently press only the top surface flat into the glaze, then pull it straight up so it only coats the high oat ridges.
Storage and Freezing: Store your iced cookies in an airtight container at room temperature for up to 4 to 5 days, placing a sheet of parchment paper between the layers so the glaze doesn't stick together. You can also freeze the un-iced baked cookies for up to 3 months; just thaw them on the counter and dip them in fresh icing before serving.
