These Rock Cakes are much better than Hagrid's which are similar in texture to actual rocks. Harry Potter would definitely approve of these raisin-filled drop biscuits.
(This recipe was originally published in August 2017, but was updated with new photos and content in 2020).
Harry Potter's birthday is July 31st. Every year I like to plan a menu inspired by the books in honor of the occasion. There's usually a savory and sweet component (dinner and dessert).
While Hagrid's rock cakes are reminiscent of actual rocks, and are quite unpalatable, these are lovely in comparison. Traditional British rock cakes or rock buns are essentially free-form scones. These are somewhat cinnamony, and studded with a plethora of plump raisins.
This recipe is extremely simple and straightforward. It reminds me a bit of American drop biscuits in the sense that it's a scone/biscuit type of dough, but it's dropped by spoonfuls onto a baking sheet.
This saves you from having to pat out the dough and cut it into shapes for baking. It also yields a rustic look (not unlike rocks).
How to make them
In a large mixing bowl combine all-purpose flour, sugar, baking powder, ground cinnamon and kosher salt. Add cold cubed butter (PHOTO 1). Cut the butter into the flour mixture with your fingers until crumbly (PHOTO 2).
Make a well in the center and add an egg beaten with milk (PHOTO 3). Combine to form a stiff dough (PHOTO 4). Fold in the raisins (PHOTO 5). Mix until just combined into a cohesive mass, but don't over-mix (PHOTO 6).
Use a large spoon to scoop mounds of dough onto a parchment paper-lined baking sheet. You should yield 12 roughly equal-sized blobs.
Bake for 25 to 30 minutes until the bottoms and edges are golden. Cool before serving.
Much like scones or American biscuits, the texture of these cakes is best the day they are made, however you can still enjoy them for a few days afterward (and they will not taste like rocks).

Rock Cakes
Ingredients
- 2 cups (250 grams) all-purpose flour
- ½ cup (100 grams) granulated sugar
- 1 teaspoon baking powder
- ½ teaspoon ground cinnamon
- ¼ teaspoon kosher salt
- 1 stick (4 ounces / 113 grams) cold unsalted butter, cut into chunks
- 1 large egg
- ⅓ cup milk
- 1 cup (150 grams) raisins
Instructions
- Preheat the oven to 350°F and line a baking sheet with parchment paper. Combine the flour, sugar, baking powder, cinnamon, and salt in a large mixing bowl. With your fingertips, rub the butter into the dry ingredients until the mixture is crumbly has the consistency of wet sand.
- Beat together the egg and the milk, then pour it into the flour-butter mixture. Stir it together using a spatula to form a stiff dough (you can use your hands too). Fold in the raisins.
- Drop dough by rounded spoonfuls 2 inches apart on the prepared baking sheet, dividing the dough evenly into 12 mounds.
- Bake for 25 to 30 minutes or until the bottoms are golden, rotating the pan partway through baking. Cool before serving.
Notes
- For rock-hard rock cakes like Hagrid’s, just bake them for too long and eat them a week later at your own risk!
- These are best the day they are made (crusty edges, soft interior), but still very good for several days afterward.
- This recipe uses kosher salt (aka cooking salt, kitchen salt, coarse salt outside of the US). If you are using table salt, definitely scale down the salt as that is a saltier type of salt! The type of salt will make a big difference in how salty your food tastes, so keep that in mind.

Please oh please can you put quantities in grams in parentheses. I have no idea how much is in a stick, mug or pail.

Hi Nick,
I attempt whenever possible to update the existing recipes on this site to include various forms of measurement including weight and volume. That being said, with hundreds of recipes it can take a while to go back through them (especially as I continue to develop new recipes as well) to add these additional measurements to the recipe cards. In general, you will find that a lot of my baking (and other) recipes do include measurements in grams, since that's my preferred measurement method as well. I have made edits to this recipe to include weight measurements which should make it easier for you to try. I hope you enjoy!

Please tell me if this is British cups (2,8 dl) or American cups (2,25 dl). I need to translate the recipe into deciliters and grams to be able to bake these.
Victoria
Hi Ulrika,
The measurements are in US cups. I hope that helps!

This was great. My mom used to make these even before HP! Thanks

I absolutely love this recipe! I've made it so many times, and they're so good. I love the rustic feel to them - they actually look like rocks!
