Crunchy oatmeal treat

Featured in Sweet treats that make you happy.

These oatmeal cookies combine crispness with softness, made with simple ingredients like ground oats, flour, creamy butter, and just a touch of powdered sugar. After shaping the dough into a mold and pre-cutting it into pieces, they bake beautifully in a controlled oven heat. By letting them cool inside the switched-off oven, you get the perfect texture and unbeatable taste. Ideal on their own or paired with coffee or tea!

This awesome oat shortbread is inspired by a Scottish favorite, but I've tweaked it so you get an outside crunch and a middle that's super tender. When you mix up ground oats with rich butter, you get cookies that are just begging to be dunked in your tea.

I always make these cookies for the holidays ever since my grandma handed down her method. Don't let how simple they are fool you—every bite is a total flavor bomb and guests are always wowed.

Hearty Ingredients

  • 1 cup rolled oats: that's 100 grams, ground for nutty taste and rough texture
  • 1 and a half cups all-purpose flour: 210 grams for a sturdy, crumbly base
  • 2/3 cup powdered sugar: 80 grams, just enough to sweeten without being too much
  • 1/2 teaspoon salt: makes all the flavors pop
  • 1 cup butter: soft and room temp—it’s key for that famous melt-in-your-mouth feel

Simple Step-by-Step Directions

Cool Down and Store:
Pull out the pan and let it chill totally before slicing or stashing them away
Slice and Let Them Set:
Take the batch out after baking, turn off your oven, cut along the marks while it’s hot, then stick the pan back in with the door closed for an hour so they set up beautifully
Bake in Two Phases:
Bake at 200°C for 10 minutes, then drop the temp to 120°C and leave them another 25-30 minutes 'til they're golden
Shape and Score:
Press dough into the prepared pan, flatten it evenly, and use a knife to draw out 16 triangle slices right on top
Add the Butter:
Toss the butter in and blend until it comes together and looks like a ball, either in the food processor or with a mixer
Mix the Dry Stuff:
If you're using a processor, drop in your flour, powdered sugar, plus salt, then pulse just a few times. If you're going old school, grab a whisk and stir them up in a big bowl
Grind the Oats:
Blend your rolled oats up in a food processor until they look like flour. How fine you go will decide how your cookies feel
Get the Oven Ready:
Fire up your oven to 200°C and lightly grease a round cake tin or springform (20 cm)

Handy Things to Know

My hands-down favorite part is truly the butter—pick the tastiest butter you can, since that's the secret to their big flavor and richness. When I was a kid, I first tried them at my Scottish grandma’s place, curled up by her fireplace, and I’ve never forgotten it.

Storage and Freshness Tips

Pop your oat cookies in a metal box with parchment between layers and they'll be great for two weeks at room temp. Don’t chill them in the fridge or they might turn weird, but you can freeze them for up to three months in a tight container.

Fun Twists to Try

Make it your own with a bunch of swaps. Lemon or orange zest brings a fresh zing. For more of a treat, add 100 grams of dark chocolate chips. Craving something extra hearty? Swap a bit of the regular flour for whole wheat—that boosts the flavor and gives a nutrition kick.

Pairings and Ideas

They're a dream with a mug of black coffee or Earl Grey. If you want dessert, plop a scoop of vanilla ice cream and pile on some berries. In Scotland, they're classic with whisky for cozy winter evenings.

Frequently Asked Questions

→ Can I use oat flour right away?

Yes! If you already have oat flour, you can skip blending the oats and use it directly.

→ What can I swap the butter with?

You can try margarine or a dairy-free alternative, but the flavor might change slightly.

→ How do I make them extra crispy?

Baking at the right temperature and letting them cool in the switched-off oven gives them that perfect crunch.

→ Can I customize them with extras?

For sure! Mix in chocolate chips, dried fruits, or spices like cinnamon to add your own twist.

→ How long can I keep them fresh?

Store them in an airtight container away from moisture, and they'll stay fresh for about a week.

Ingredients

→ Dough

01 1 cup (about 225 grams) of room-temperature butter
02 ½ teaspoon of salt
03 80 grams of powdered sugar
04 210 grams of regular flour
05 100 grams of oat flakes (or ⅓ cup of oat flour)

Instructions

Step 01

Turn your oven to 200°C (400°F) and grease a 20 cm round cake pan or springform pan lightly.

Step 02

Use a blender or food processor to grind the oat flakes into fine powder. Skip this if you're already using oat flour.

Step 03

If you're using a food processor, add the flour, sugar, and salt to the bowl and give it a quick mix. Doing it manually? Just whisk the oat flour and dry stuff in a mixing bowl.

Step 04

Drop the butter in and mix everything until it forms a smooth dough. You can do this with a food processor or an electric mixer.

Step 05

Spread out the dough in your prepared pan and use a knife to divide it into 16 equal sections.

Step 06

Put it in the oven for 10 minutes at 200°C (400°F). Then lower the temperature to 120°C (250°F) and bake for another 25–30 minutes until the edges turn golden.

Step 07

Once it's out of the oven, use a sharp knife to cut along the lines you made earlier.

Step 08

Place it back in the oven, but this time with the oven switched off and still warm. Leave it inside for an hour with the door shut to dry and crisp up.

Step 09

Take it out of the oven and let it cool all the way before removing it from the pan.

Notes

  1. To get a crunchier texture, don't skip letting the shortbread dry in the warm oven.
