Lemon Crumb Cake is a New York style coffee cake with a delicate fresh lemon flavor, made with my special lemon infused sugar.
lemon crumb cake is a classic New York style coffee cake
I patterned this recipe after one of my favorite coffee cakes on the blog, my Cardamom Crumb Cake. I made it for the family and realized it was too good not to share with you guys. It bakes up nice and tall, and it’s fluffy on the inside with a nice thick nubbly crumb crust on the top. But best of all it’s laced with the most delicate lemon flavor ~ that’s because the flavor is infused into the sugar that then bakes into the cake. The kitchen smells incredible, and everybody lunges for the first piece.
Here’s what readers are saying about this simple lemon crumb cake:
- “Another great recipe! This cake rises so high, and is the perfect crumb.”
- “This came out just like the picture! I’m so stoked.”
- “Already looking forward to making it again!”
- “Thanks for the recipe will be my forever go to!!!
You know I adore lemon, and I’m always on a quiet crusade to find better ways to get real lemon flavor into my baking. This is one of my favorite techniques, and you may remember it from my buttery Lemon Sugar Shortbread (still one of my all-time favorites).
A food processor is the perfect tool for making lemon sugar. I simply process the clean lemon peel (removed with a vegetable peeler) with the sugar until it transforms into a fragrant citrus sugar ~ it takes just seconds, and the flavor payoff in this lemon crumb cake is huge.
common questions about lemon crumb cake
You’ll grate the lemon zest with a grater and mix with the sugar. In that case I recommend grating the zest of 2 lemons.
You can use regular whole milk instead.
Yes, sure. let it cool completely first, then wrap in foil, and again in plastic. Plan to use within 3 months.

Lemon Sugar Crumb Cake
Video
Equipment
- full sized food processor
- 9×9 baking pan
Ingredients
- 1 lemon, organic preferred, well washed and dried
- 1 3/4 cups granulated sugar
- 2 1/2 cups all purpose flour
- 1 Tbsp baking powder
- 1/2 tsp salt
- 2/3 cup cold unsalted butter cut in small pieces
wet ingredients
- 2/3 cup milk
- 2 large eggs
- 1/4 cup sour cream
- 1 tsp vanilla extract
Instructions
- preheat oven to 325. Spray a 9×9 square baking pan and line with parchment paper if you want to be able to lift it out for cutting. This is optional.
- Use a serrated vegetable peeler to carefully peel away the zest from the lemon. You want only the yellow, not any of the bitter white pith.
- Put the sugar into the bowl of a food processor, along with the zest. Process, scraping down the sides if necessary, for about a minute or so, until the zest is completely incorporated into the sugar.
- Add the flour, baking powder, and salt into the processor and pulse to combine everything.
- Add the butter to the bowl. Pulse to combine, maybe about 20 pulses. The mixture should be crumbly with the butter well distributed and in very small pieces.
- Measure out 1 cup of the mixture and set aside.
- Whisk together the wet ingredients and add to the dry, mixing just until combined. Spread the batter into the pan, and top with the reserved crumbs. Note: I use my fingertips to make some larger, chunkier crumbs to create a nice texture on the top. Just compress the dry mixture a little between your fingers to make any size crumb you like.
- Bake for about 40 minutes, until a toothpick comes out without wet batter clinging to it, moist crumbs are fine.
Notes
- I like to use organic lemons when I know I’ll be using the peel, and I wash them really well.
- If you don’t have a food processor you can do this by hand. Grate the lemon zest and mix with the sugar. I would use the zest of 2 lemons if you are doing it by hand.

Does it make a difference if you use regular lemons or Meyer lemons?
No, go with either.
I have made this cake twice in the last week. The first time exactly as recipe is called for. Today I made it with orange instead of lemon. I love both ways. I squeezed some of the orange juice into batter. Delicious, thank you for a great recipe.
You’ve tempted me Cheryl, we actually have some oranges right now and it sounds lovely!
I made this today exactly as written. It s delicious, has a tender texture and makes the house smell wonderful ! Most recipes take a lot longer for prep than the author states, not this one. It really was in the oven in less than 15 minutes with less 10 minutes of cleanup. I’m going to be putting my house on the market soon. I’ll be baking this prior to showings that give me enough warning.
Totally fell in love with this recipe. Since my oven is small, I made half recipe. It turned out sooo gewd! Moist with crunchy crumble on top. So so gewd!! Thank you for sharing the recipe. Definitely a keeper!
Thanks Cindy, glad you loved this one 🙂
I notice you don’t call for any of the juice from the lemon???
No, not in this recipe. Lemon juice is basically just sour ~ all the lemon flavor is in the zest.
I used the lemon juice, used it along with the milk to make 2/3 cup. It was delicious!
Does this make a thick enough batter to fold in blueberries to the cake? Love lemon with blueberries.
The batter is pretty thick, so go for it!
Hi Sue! Love your blog. This lemon cake sounds heavenly, but I’m wondering if I can use less sugar in the recipe. Perhaps a combo of Splenda for baking and your homemade lemon sugar? My hubby and I are trying to cut back on sugar consumption, but this cake would be a wonderful treat. What do you think? Thank you.
This is one of those cases where I think you just have to experiment, Donna. I’m sure you can cut back, I know the rule of thumb is you can usually cut down about 1/3 of the sugar in a baking recipe with reliable results. I don’t have a lot of experience with Splenda, but I think it’s definitely worth a try. Let us know how it goes!
Hi my name is Wendy I have just joined please can you tell me what you mean by allpurpose flour is plain or self razing
Xx
When I say flour it’s always all plain flour, not self raising. Welcome in Wendy 🙂
Hi. I can’t wait to try this recipe. Did you sprinkle anything on top of the crumbs they look like it in picture
No, that’s just the way the crumbs come out, you’ll see when you make it, it’s not the usual kind of crumbly topping, it’s lighter and less nubbly.
I made the cake today and it turned out great! Super delicious. Thanks so much. Already looking forward to making it again.
I’m so happy to have a ‘go to’ source.
I’m so glad Jeanette!
