This lemon crunch cake is an old fashioned style breakfast or snack cake with a pillowy soft texture, bright lemon flavor, and a delightfully crunchy top.
lemon crunch cake is the latest addition to my collection of lemon cakes
I’ve made a lot of luscious, lemon-y cakes over the years, and my excuse to add another one to the list was the crunchy sugary topping on this one. But it’s not all about the topping, the texture and flavor of the cake itself is top notch, it’s super soft, moist, and layered with lemon flavor. It makes a fantastic breakfast treat, but this lemon-lover’s cake can stand in for dessert, too. I’d love to see it served with a dollop of freshly whipped cream and some fresh berries (blueberries would be awesome.)
What you’ll need
- lemons ~ for the juice and zest. I use my fabulous lemon sugar technique for this cake, which really emphasizes that citrus flavor. Read all about how to infuse lemon into sugar, here.
- flour ~ I use all purpose, but cake flour will work, too.
- sugar ~ granulated.
- butter ~ unsalted
- eggs ~ large
- buttermilk ~ adds tang and tenderizes the texture.
- baking powder and baking soda ~ react with the acidity in the lemon and the buttermilk to rise the cake.
- lemon extract (optional) ~ the cake gets its lemon flavor from lemon zest, but extract doubles down on the citrus vibe.
What makes the ‘crunch’ in lemon crunch cake?
The “crunch” in this cake comes from a generous sprinkling of sugar over the top of the batter before it goes in the oven. As the cake bakes, that layer of granulated sugar becomes a very light, crisp, sweet topping that really makes this cake special. This trick can be used to great effect in other recipes too, so keep it in your back pocket! My Amish Cinnamon Bread uses this same technique to make that fun, crackly top.

Lemon Crunch Cake
Equipment
- 9×9 baking pan
Ingredients
- 1 cup granulated sugar
- zest of 1 lemon, peeled with a vegetable peeler into strips. You want the yellow part, with as little of the bitter white as possible. Note: you don't want the peel of the lemon, just the outer zest. Use a serrated vegetable peeler for best results and just peel off the yellow part, leaving the bitter white behind.
- 1/2 cup unsalted butter, at room temperature
- 2 large eggs, at room temperature
- 1 1/2 cups all purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup buttermilk
- 1/4 cup fresh lemon juice
- 1/2 tsp lemon extract
topping
- 1/4 cup granulated sugar
Instructions
- Preheat oven to 350F. Lightly spray and line a 9×9 baking dish with parchment paper. The paper is optional but helps lift the cake out for easy slicing.
- Put the sugar and zest in a food processor and process until the zest is completely incorporated, and the sugar is moist and pale yellow. Note: if you don't have a processor then grate the zest of 1 lemon and mix with sugar by hand.
- Cream the butter and sugar together in a stand mixer, or in a bowl with a hand held mixer.
- Beat in the eggs, scraping down the sides of the bowl as necessary.
- Whisk together the flour, baking powder, baking soda, and salt in a separate bowl.
- Add the lemon juice and extract to the buttermilk.
- Alternately add the flour and buttermilk to the creamed sugar and eggs. Begin and end with the dry ingredients. Blend until everything is well combined, but don't over mix.
- Spoon the batter into the prepared pan and smooth out evenly. Sprinkle the sugar evenly over the entire surface. Note: I know, it seems like a lot, but go with it, it makes a nice crust.
- Bake on the middle rack for about 30 minutes, or until golden.

What a delicious cake & so lemony. Definitely will make it again. I wondered if it freezes well?
It should freeze fine 🙂
This cake is just so delicious. I know it will be a hit at my friends dinner party. Nothing like a lemon cake and coffee to end a dinner. Keep up the good work.
Thank you Joan <3
Yummy recipe. Have you tried making muffins from this recipe?
I haven’t but it should work fine.
Looks delicious! Can the recipe be doubled and baked in a larger pan? Plan on making it for an adult birthday and topping with whipped cream and blackberries.
Yum! I think you should be able to double it for a 9×13 pan.
Sounds tasty! Do you use additional sugar to sprinkle on top, or do you set aside part of the lemon sugar? I only see one cup of sugar in the recipe, but it’s added twice. Thanks!
LOL Never mind, I found it! I read the recipe three times looking for that extra sugar, too!
But you bring up a good point, you could make 1 1/4 cups lemon sugar and then use the extra 1/4 cup for the top, I like the idea, and will try next time I bake this!
This is a truly scrumptious cake !!!
Just made fabulous
Love your quick work Peggy, thanks for the feedback 🙂
You had me at lemon..had to try it. Made it this morning and can’t stop tasting it. Mine came out very moist and dense but very light.
I will definitely be making this again and again.
Thanks for sharing
Yay Mary Ann, thanks!
Good morning
May I use a metal or glass 9×9 pan?
Thank you for sharing this,
Robyn
Hi Robyn, I’d use a metal pan, glass can bake unevenly. Hope you love it!
Thank you I’m sure we will :))
I’ll keep you posted
Robyn
I am an experienced baker, and I’ve never had any issues caused by a using a glass pan.
Hi Sue,
This cake looks delicious. I have celiac disease. Can I use gluten free flour instead of all purpose flour?
Thanks,
Kathy
Yes, you can use your favorite gf flour mix for this, it should be fine.
