Recipe inspiration often comes from unexpected places. For me it was a beautifully designed box of cookies at a gourmet shop. With my obsession with fonts and strong sense of aesthetic, I was instantly smitten by the packaging. I couldn’t resist buying the Oat Chocolate Crumbles—and broke into the box before I even made it home.
The packaging caught my eye, but it was the cookies that truly wowed me—chocolate-coated, chewy in the center, and crispy on the edges. Naturally, I had to recreate them. Research revealed they were an elevated take on “Hobnobs” the classic British biscuit. My version of chocolate dipped oat crumble cookies aims to capture that same essence.
This oat crumble cookies recipe uses wholesome ingredients like whole grain oats and whole wheat flour. They make the cookies not only delicious but also almost healthy. I added some gold sanding sugar and edible gold leaf because fancy is how we roll around here at salt and serenity.

Tips for Success
1. Use Golden Syrup, Not Corn Syrup
Golden syrup, a key ingredient in these chocolate-dipped oat cookies, adds a rich, caramel-like flavour that’s essential to their signature taste. Unlike the neutral sweetness of corn syrup, golden syrup brings depth and a buttery caramel note that makes these oatmeal cookies stand out. While corn syrup is made from cornstarch and has a mild flavour, golden syrup is made from sugar and offers a more pronounced, complex sweetness.
2. Choose Rolled Oats, Not Instant Oats
To achieve the perfect balance of chewiness and crispiness, use rolled oats (also called old fashioned oats) in your homemade oat cookies. Instant oats are too fine and can alter the texture. Rolled oats also provide more structure, making these British Hobnob-inspired cookies wonderfully satisfying.
3. Mix Coconut Oil into Melted Chocolate for Dipping
Want that glossy, professional finish for your chocolate-dipped cookies? Two teaspoons of coconut oil mixed into the melted chocolate keeps the coating shiny after it sets. Your baked treats will look Instagram-worthy.
4. Use Bamboo Tweezers for Applying Gold Leaf
When working with edible gold leaf in baking, bamboo tweezers are your best tool. Unlike metal tweezers or your fingers, bamboo creates less static, making it easier to handle the delicate gold leaf without tearing or smudging. This small detail ensures your fancy cookies with edible gold look flawless every time.
How to store your Oat Crumble Cookies
To keep your homemade oat cookies fresh and delicious:
1. In an Airtight Container: Store the cookies in a sealed container at room temperature for up to 5 days. This keeps them chewy in the center and crispy on the edges.
2. In the Fridge: If you live in a warm climate, you can refrigerate them for up to a week. Allow the cookies to come to room temperature before serving for the best texture.
3. Freezing Option: These cookies freeze beautifully! Place them in a freezer-safe container with parchment paper between layers to prevent sticking. They’ll keep for up to 3 months—just thaw them in the fridge or at room temperature when you’re ready to enjoy.
Oat Crumble Cookies
Ingredients
Cookies
- 250 grams unsalted butter removed from fridge 30 minutes before making dough
- 160 grams light brown sugar
- 78 grams golden syrup
- 188 grams rolled oats also called old fashioned oats
- 200 grams wholewheat flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon Diamond Crystal Kosher salt or 1/2 teaspoon Morton's Kosher salt
For coating cookies
- 200 grams bittersweet or semi-sweet chocolate coarsely chopped
- 2 teaspoons coconut oil
- 2 Tablespoons flaky sea salt
- 200 grams edible gold leaf flakes optional
- 100 grams gold sanding sugar optional
Instructions
Cookies
- In a large bowl, with a hand mixer, or stand mixer fitted with paddle attachment, cream together butter and sugar until pale and smooth, abut 3-4 minutes.
- Add golden syrup and beat well to combine. Mix in oats. Mix in whole wheat flour, baking powder, baking soda and salt.
- Line a baking sheet with parchment paper and Using a 1.5 inch ice cream scoop, (I used this one),scoop out mounds of dough. Place scoops on parchment lined cookie sheet. They can be right next to each other on the baking sheet for now, as you are just putting them there to chill. Cover baking sheet with plastic wrap to prevent cookies from absorbing unwanted fridge odours. Chill dough for at least 1 hour, or up to 24 hours.
- Preheat oven to 350°F. Stack 2 half sheet pans (13×18 inches) together, lining the top sheet with parchment paper. Doubling the baking sheets insulates the bottom of the cookies so they do not get burned.
- Place on baking sheet, leaving at least 2 inches between cookies, as they will spread as they bake. I fit 8 cookies onto a half sheet pan (13×18 inches).
- Bake for 7 minutes. Turn baking sheet 180°. Continue baking for an additional 6-7 minutes. The cookies may be a bit irregular looking, and not completely circular. While they are still warm, use a cookie cutter slightly bigger than the cookie to "scoot" the cookies (swirling motion to make cookies round again) Repeat with remaining cookie dough.
Decorating
- Melt chocolate and coconut oil together in a heatproof bowl set over a pan of simmering water or in the microwave, for 1 minute at 50% power. Stir until melted.
- Dip the bottom (flat surface) of each cookie in the melted chocolate and let excess drip off. Place on parchment lined baking sheet, chocolate side up and let harden.
- Transfer any leftover melted chocolate to a disposable piping bag. Pipe a few decorative lines of chocolate onto cookie and while still wet, sprinkle lightly with sanding sugar and sea salt. If using gold flakes, apply a few tiny flakes to each cookie, using small bamboo tweezers.
- Store cookies in airtight container for 3-4 days or freeze for up to 6 weeks.
