I always look forward to using fresh lemon zest for this cake. The aroma as you zest the lemon fills the kitchen and it brings such a fresh essence to the whole dessert. My kids love picking out lemon slices as decoration before we dig in—always a favorite finishing touch.

Storage Tips

After slicing the cake wrap each piece in foil and place in a zip top bag to keep them fresh in the fridge. Remember to store lemon slices separately so they do not make the cake wet. For long term storage freeze slices in foil and bring to room temperature before eating—you can microwave briefly for softness.

Ingredient Substitutions

You can use any plant based milk in place of dairy milk to keep things vegan or allergy friendly. For the frosting swap in a vegan baking stick instead of butter and make sure your gluten free flour has xanthan gum to keep the cake structure optimal. If you run out of lemons bottled lemon juice can fill in but the zest from fresh lemons is key for pure lemon flavor.

Serving Suggestions

Serve this cake as the grand finale for any celebration or holiday spread garnished with extra lemon zest or gluten free sprinkles for a pop of festivity. It pairs beautifully with fresh berries on the side or a dollop of coconut whipped cream if you want to take it up another notch.

Steps

Step 01

Preheat oven to 175°C. Grease and line two 20 cm round cake pans with parchment paper. Set aside.

Step 02

Wash and dry lemons thoroughly. Zest 3 medium lemons to yield 2 tablespoons zest and juice 2 lemons to obtain 60 millilitres juice.

Step 03

In a large mixing bowl, whisk together gluten free flour, granulated sugar, baking powder, baking soda, salt, and lemon zest until uniform.

Step 04

In a separate bowl, whisk together milk of choice, light brown sugar, vegetable oil, lemon juice, and vanilla extract until fully combined.

Step 05

Gradually pour wet mixture into dry ingredients. Mix gently with a spatula until just combined; avoid over-mixing. Batter will thicken as combined.

Step 06

Divide batter evenly between prepared pans. Smooth tops with a butter knife. Bake on center rack for 35 minutes until a toothpick comes out clean.

Step 07

Cool cakes in pans for several minutes, then transfer to wire rack and allow to cool completely. Once cooled, carefully slice each cake horizontally to create four even layers.

Step 08

In a large bowl, beat butter or vegan baking stick with electric mixer until creamy, about 2–3 minutes. Add vanilla and lemon zest, beating to integrate. Gradually add half of the confectioners' sugar, 30 millilitres lemon juice, and 35 millilitres water, beating until combined. Add remaining sugar, juice, and water; beat until smooth and fluffy.

Step 09

Place one cake layer on serving plate. Spread approximately one-fifth of the frosting (about 1 cup) evenly over the surface. Repeat with two additional layers and frosting. Position final layer, flat side up, for a smooth finish.

Step 10

Using remaining frosting, apply a thin layer over the top and sides of cake to seal in crumbs. Refrigerate uncovered for 15 minutes for stability.

Step 11

Remove cake from refrigerator. Finish with an even layer of frosting. Use an icing spatula to create texture if desired. Transfer extra frosting to a piping bag and pipe swirls around the top edge. Garnish with white nonpareils, fresh lemon zest, and lemon slices if using.

Notes

  1. After slicing, wrap each piece in foil and store in an airtight bag in the refrigerator for best freshness.
