Step‑by‑Step Instructions for Lemon Crunch Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 9×9 inch baking pan by lightly greasing it with cooking spray or lining it with parchment paper. This will ensure easy removal of your delicious lemon crunch cake once it’s baked to perfection.
Step 2: Prepare Lemon Sugar
In a food processor, combine the granulated sugar and lemon zest. Pulse the mixture until it appears well blended and moist, releasing the fragrant citrus oils. This step infuses the sugar with bright lemon flavor, which will enhance the overall taste of your lemon crunch cake.
Step 3: Cream Butter and Lemon Sugar
In a stand mixer, add the softened unsalted butter along with the prepared lemon sugar mixture. Beat on medium speed until the mixture becomes fluffy and light, about 3-5 minutes. Then, incorporate the large eggs one at a time, mixing well after each addition to ensure a smooth, creamy batter.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This process helps to evenly distribute the leavening agents throughout the flour, which is essential for a uniform rise in your lemon crunch cake. Set the dry mixture aside for the next step.
Step 5: Mix Wet Ingredients
In a measuring cup, mix the buttermilk with fresh lemon juice and lemon extract. Stir gently until combined; this will create a tangy, lemon-infused liquid. Adding the wet ingredients this way will ensure the flavors meld beautifully when incorporated into the batter.
Step 6: Incorporate Dry and Wet Ingredients
Gradually add the dry flour mixture to the creamed butter mixture, alternating with the buttermilk mixture. Start and end with the dry ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can lead to a dense lemon crunch cake.
Step 7: Transfer Batter
Spoon the luscious batter into your prepared baking pan, smoothing the top with a spatula. Make sure it’s evenly distributed for uniform baking, which will give your lemon crunch cake a beautiful, tender crumb once it’s baked.
Step 8: Add Topping
Sprinkle the extra granulated sugar evenly over the surface of the batter. This crucial layer will form a delightful crispy topping as your lemon crunch cake bakes, adding that signature crunch that makes this dessert so irresistible.
Step 9: Bake
Place the pan in the preheated oven and bake for approximately 30 minutes. You’ll know the lemon crunch cake is done when it turns golden brown, and a toothpick inserted in the center comes out clean. Keep an eye on it towards the end to prevent overbaking, ensuring that perfect texture.

Expert Tips for Lemon Crunch Cake
-
Fresh Ingredients: Always check the freshness of baking powder and eggs. Stale ingredients can lead to a flat, dense cake rather than the light texture you desire.
-
Avoid Overmixing: Mix until just combined to prevent toughness; excessive mixing develops gluten, making the cake dense rather than pillowy soft.
-
Crucial Topping: Don’t skimp on the extra sugar for the topping. This layer is essential for achieving that satisfying, crunchy texture that contrasts beautifully with the moist cake.
-
Room Temperature Components: Ensure that your butter and eggs are at room temperature. This helps them blend smoothly and incorporate air, resulting in a fluffier lemon crunch cake.
-
Zest with Care: Use fresh lemon zest for the best flavor. If fresh lemons aren’t available, bottled zest can work but may lack the same aromatic punch.
How to Store and Freeze Lemon Crunch Cake
Room Temperature: Keep the cake in an airtight container at room temperature for up to 3 days to maintain its delicious texture and flavor.
Fridge: If you want to prolong freshness, refrigerate the lemon crunch cake for up to a week. Wrap it tightly in plastic wrap to prevent it from drying out.
Freezer: For long-term storage, freeze the cake for up to 3 months. Wrap it well in plastic wrap and then in aluminum foil or a freezer-safe container to protect against freezer burn.
Reheating: To enjoy leftovers, thaw in the fridge overnight and reheat in the oven at 350°F for about 10 minutes. This will restore its moist texture and crunchy topping!
Make Ahead Options
These Lemon Crunch Cake is perfect for busy cooks who want to save time without sacrificing flavor! You can prepare the lemon sugar mixture and batter up to 24 hours in advance. Simply store the lemon sugar in an airtight container at room temperature and the batter in the fridge (to prevent any rising). When you’re ready to bake, transfer the batter to the prepared pan and sprinkle the crunchy sugar topping right before placing it in the oven. This way, your cake retains its texture and freshness, delivering that same irresistible lemony delight. Enjoy having a homemade dessert ready with minimal effort on the day of serving!

Lemon Crunch Cake Recipe FAQs
How do I choose the right lemons for my cake?
Absolutely! Choose lemons that are firm and vibrant in color, free from dark spots or blemishes. A fragrant lemon is likely to have more juice and zest. For the best flavor, opt for fresh lemons instead of bottled options.
How should I store my Lemon Crunch Cake after baking?
Very simple! Store the cake in an airtight container at room temperature for up to 3 days. If you want to keep it fresh longer, refrigerate it wrapped tightly in plastic wrap for up to a week.
Can I freeze Lemon Crunch Cake?
Yes, you can! To freeze, first ensure the cake is completely cooled. Wrap it tightly in plastic wrap and then in aluminum foil or place it in a freezer-safe container. It can be frozen for up to 3 months. To thaw, simply leave it in the fridge overnight and reheating in the oven at 350°F for about 10 minutes will bring back its deliciousness!
What should I do if my cake doesn’t rise properly?
If your Lemon Crunch Cake doesn’t rise, it could be due to stale baking powder or baking soda. Always ensure these leavening agents are fresh. Mixing the wet and dry ingredients too vigorously can also lead to poor rise; mix until just combined. If you encounter this issue, you might try adding a bit more baking powder next time.
Is this cake suitable for people with allergies?
Great question! The Lemon Crunch Cake contains common allergens like eggs and dairy. If you’re looking for a dairy-free version, consider substituting butter with a plant-based alternative and buttermilk with a non-dairy milk plus vinegar. For egg-free options, you could try unsweetened applesauce or a commercial egg replacer.
Can I add other flavors or ingredients to this cake?
Absolutely! Feel free to experiment with different citrus zests like lime or orange. Adding poppy seeds can bring in a delightful crunch and visual appeal, or you could top the cooled cake with a simple powdered sugar glaze made from lemon juice and sugar for an extra layer of sweetness.
