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.

  • 9×9 baking pan


  • 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


  • 1/4 cup granulated sugar


  • 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.

  • 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.

    The cake was enjoyed by all. I had to give the recipe to a few. The only thing is the cake sunk in the middle. The toothpick test showed it was baked completely thru. But while it was cooling the middle sunk in. I’m lost why, can you think of any reason for this to happen???? Please let me. I only used yogurt instead of buttermilk.

      Sometimes toothpick tests can be deceiving. It does sound like it didn’t quite get a chance to cook completely through.

    Can you suggest a non-dairy replacement for the buttermilk?

      You might use coconut or almond milk instead.

    I’d like to make this crunch cake for an upcoming function. Is it best eaten the day it’s baked, or is it better the next day?
