Update: Homemade Ferrero Rocher achieved!
Rum Glazed Sour Cream Doughnuts with Walnut Streusel
Adapted just barely from Bon Appetit
Makes 2 dozen doughnuts and holes
Streusel:
1 large egg white
1/4 cup sugar
1 teaspoon ground cinnamon
2 cups chopped walnuts (about 6 ounces)
Doughnuts:
3 1/2 cups all purpose flour
1 tablespoon baking powder
1 teaspoon ground cinnamon
1 teaspoon salt
1/2 teaspoon baking soda
1 cup sugar
2 large eggs
2 teaspoons (packed) finely grated orange peel
1/2 teaspoon vanilla extract
1/3 cup melted unsalted butter, cooled briefly
1 cup sour cream
Glaze:
2 cups powdered sugar
1/4 teaspoon rum extract (can substitute vanilla if preferred)
5 tablespoons (about) heavy whipping cream
Canola oil (for deep-frying)
For streusel: Preheat oven to 300°F. Line rimmed baking sheet with parchment paper. Whisk egg white in bowl until frothy, about 1 minute. Whisk in sugar and cinnamon. Fold in nuts. Spread mixture on prepared sheet. Bake until beginning to dry, about 12 minutes. Using metal spatula, stir to break up nuts. Continue to bake until nuts and coating are dry and golden brown, about 10 minutes; cool on sheet. Transfer streusel to work surface. Chop nuts into small (rice-size) bits. Transfer to shallow bowl.
For doughnuts: Whisk first 5 ingredients in medium bowl to blend. Using electric mixer, beat sugar and eggs in large bowl until very thick, about 3 minutes. Beat in orange peel and vanilla. Gradually beat in butter; beat in sour cream in 2 additions. Gently fold in dry ingredients in 4 additions (dough will be slightly sticky). Cover; set aside 1 hour.
For glaze: Combine powdered sugar and rum extract in medium bowl. Add 4 tablespoons cream; whisk until smooth. Whisk in additional cream, 1 teaspoon at a time, to form medium-thick glaze. Cover and let stand up to 3 hours.
Sprinkle 2 rimmed baking sheets lightly with flour. Press out 1/3 of dough on lightly floured surface to 1/2- to 2/3-inch thickness. Using 2 1/2-inch-diameter round cutter, cut out dough rounds. Arrange on floured sheets. Repeat with remaining dough in 2 more batches. Gather all dough scraps. Press out dough; cut out more dough rounds until all dough is used.
Using 1-inch-diameter round cutter, cut out center of each dough round to make doughnuts and doughnut holes.
Line 2 baking sheets with several layers of paper towels. Pour oil into large deep skillet to depth of 1 1/2 inches. Attach deep-fry thermometer and heat oil to 365°F to 370°F. Fry doughnut holes in 2 batches until golden brown, turning once, about 2 minutes. Using slotted spoon, transfer to paper towels. Fry doughnuts, 3 or 4 at a time, until golden brown, about 1 minute per side. Using slotted spoon, transfer doughnuts to paper towels. Cool doughnuts and doughnut holes completely.
Working with 1 doughnut at a time, spread glaze over 1 side, then dip glazed side into streusel. Arrange doughnuts, streusel side up, on rack. Let glaze set at least 30 minutes. Coat doughnut holes with same glaze and dip into streusel.

Comment Guidelines
Most of the comments and emails I receive are positive, conversational, and very welcome as part of the dialogue that I love about the food blogging community. Unfortunately, there is still a minority of comments that are offensive, irrelevant, and sometimes simply rude. Of course, the misfortune about creating comment guidelines is that the people leaving the former kind of comments are already following the guidelines, and the people leaving the latter kind of comments probably won't bother to read the guidelines or will simply ignore them. Still, please follow the guidelines. It will make the online world a better place for all of us.
The Good Kind of Comments:
- Conversational. If you're starting or continuing a conversation about your life, your experiences in the kitchen, or stories about your family, then I love and welcome your comments. The ability to genuinely connect with other people with similar interests whom I may never otherwise meet is one of the things I most love about the food blogging community, and I encourage people to participate as much as they'd like in these sometimes spontaneous conversations.
- Feedback. If you tried a recipe that you found on The Red Spoon, I would love to hear about it. Whether it was a success or a flop, whether you added ingredients or adjusted cooking times, whatever you did, I am always interested in hearing how things went in another kitchen with the same recipe.
- Questions. If something in a recipe is confusing or obviously wrong, please feel free to ask a question. Or, if you're just really curious about where we bought the cutest outfit on the latest Henry cameo, don't be shy at all about asking.
The Bad Kind of Comments:
- Irrelevant. I'm pretty open minded about the kinds of conversations that might happen in the comments section, but the ones I'm referring to here are things like permission requests, recipe requests, advertising requests, etc. that would be more appropriate in an email. A good rule of thumb is that if the comment will alienate everyone else reading the post, try putting in an email directly to me instead.
- Linking. As part of the comment in-take form, there is a field where you can enter your website or blog and it will appear as a hyperlink embedded in your name in the text of the comment. This kind of linking is perfectly acceptable. When linking is not acceptable is if the corresponding comment is completely irrelevant, i.e. an excuse to market your website on my website, in which case your comment will be deleted for irrelevance, or if you leave a link in the body of the comment. The rule of thumb is don't try to market your website on my website. I know all the tricks and I will delete your comment if I think this is what you're doing.
- Nastygrams. Every once in a while I find one of these in my inbox or in a comment on a post. People sending me nastygrams: don't do it. You're wasting your time. I really don't care if you think my blog "looks like" another blog, of if you think talking about my kid and putting pictures of him in posts is "copying" another blog. Seriously. The blog you're rushing to defend probably didn't come up with that one either, and even if they did there is nothing illegal, unethical, or unfair about doing the same thing. If you're genuinely concerned that plagiarism has taken place on The Red Spoon, just send me a polite email asking if I forgot to credit someone somewhere. But when you leave an anonymous comment saying that my website is ugly, you have become that annoying kid on the playground that wants to correct everyone but that no one else likes, except you're not a kid so what's your excuse? Your comment will be deleted, your email won't be responded to, and thank you for the page views and corresponding advertising revenue.
- Parenting Advice. Josh and I love being parents, and we definitely need all the help we can get, but from the people that are actually involved in our daily lives and know what help we need. Please don't leave parenting advice in the comments sections. Such comments will be deleted.
I have never had sour cream donuts, but that ingredient does quite well in cakes-so I am sure it makes for a great doughnut! The walnut streusel really makes these special. Your pictures sure are making me crave some. Well done.
Wow…these look amazing. Another recipe to add to my list of things I must make and soon.
You make donut making look so easy. What a delicious looking recipe. Come over and visit. We have a wonderful waffle recipe today.
I have yet to actually make doughnuts. I need to get on it! These look amazing and surprisingly simple to make which is always a plus.
These turned out beautifully. Much better then the smooshed things I saw at the bakery today.
I too would love to try making Ferrero Rocher at home but have held off because if I found a good recipe I’d make and eat them all the time, which would lead to me becoming one of those people you see getting vut from their house!
I had a little look and thought this recipe might interest you. http://palachinkablog.com/homemade-ferrero-rocher/
Good luck and all the best with your impending addition!
Hi! I know this recipe is an older link, but I wanted to make it and had to ask, how much butter is added to the dough recipe? It’s not listed that I see but it’s mentioned in the doughnot instructions. Thanks! P.S. I really like your blog!
Hi Jennifer, it’s 1/3 cup melted unsalted butter. I added it to the ingredient list above. And thank you!
