Lachlan’s Triple Layer GF
Lemon-Blueberry Birthday Cake
Happy (not so) sweet 16th birthday to the little brother. For weeks he had harped on about making peanut butter icing (see one of my earlier posts), and then after a shock body fat percentage reading the week before his birthday, he decided that he didn’t want peanut butter icing, he wanted a fruity cake that was gluten-free. Well, that ruined my plans for an 8-layer chocolate-peanut extravaganza. So I started trawling the web for cake ideas, and the lemon/blueberry combo jumped out at me. I can’t say it’s any healthier than the chocolate extravaganza (ok, well maybe marginally), but it’s easily as delicious and while rich, the zestiness (is that a word?) of the lemon is refreshing, especially after a massive birthday lunch. I spent the best part of my Saturday making the cake, then creating the filling and finally late Saturday night, assembling this delicious monster. It consisted of a layer of lemon-blueberry cake, a layer of vanilla cake and another layer of lemon-blueberry cake, sandwiched with homemade lemon-curd and iced with lemon frosting. For those who haven’t made a layer cake, the anticipation is a killer. Unlike a cupcake, you can’t use one to test, and you can’t cut it open to double check if it looks as good as you’d hoped. Thankfully, this beauty turned out (almost) perfectly. After my weekend Colombaris fest (Press Club with a friend on Saturday night followed by a birthday lunch at St Katherine’s), the family finally tucked in to a piece of this beauty. Yum. I can tell you it was certainly worth the previous day’s effort, and even when we thought we couldn’t stomach another morsel of food in our already bulging tum-tums, we all managed to down a piece. Easily. In other news, I’m about 32 weeks pregnant with a food baby…
Blueberry Cake (top and bottom layer)
2 cups plus 6 tablespoons gluten-free plain flour
2 teaspoons baking powder
1 teaspoon salt
3 cups fresh blueberries (smaller the better)
1/2 cup sour cream
1/2 cup milk
2 teaspoons vanilla extract
3/4 teaspoon pure lemon extract
1 teaspoon lemon zest
250g unsalted butter, softened
1 1/2 cups castor sugar
4 large eggs
1. Preheat oven to 180C. Prepare two 8″ round cake pans with baking paper, and grease the edges with butter or spray.
2. Sift dry ingredients (except sugar) into medium bowl. Transfer 1 tablespoon flour mixture to larger bowl. Add fresh blueberries and toss to coat them with flour. Set remaining flour mixture and blueberries aside.

3.Stir milk, sour cream, vanilla extract, lemon extract and lemon zest in small bowl.
4. In the bowl of a stand mixer, cream butter and sugar, until pale yellow and very fluffy, about 5 minutes. Beat in eggs one at a time, until well combined.
5. Mix in flour mixture alternately with milk mixture, starting and ending with flour mixture. Stir until just combined. Gently fold in blueberries.

6. Divide batter equally between pans. Bake cakes until toothpick inserted into centre comes out clean, about 25 minutes, or until a skewer comes out clean.
Vanilla Cake (middle layer)
3/4 cup gluten-free S/R flour
1/2 cup castor sugar
1/4 cup milk
30g melted butter
1 egg
1. Preheat oven to 180C. Prepare an 8″ round cake pan with baking paper, and grease the edges with butter or spray.
2. Combine all ingredients with an electric beater, beating until smooth and pale in colour.
3. Pour into cake pan and bake for 15-18 minutes or until a skewer comes out clean.
This cake doesn’t come without its own hazards, either. I sustained second-degree burns to my finger removing one of the pans from the oven. Ouch. I’ve now lost feeling in the tip of that finger and am pretty sure I’ve burnt my finger-prints off. Lovely. The moral of the story is, buy Liv a pair of oven mitts for Christmas. But seriously, it hurts, so be careful.
Once you’ve removed your cakes from the oven and have them sitting peacefully on a cake rack to cool, you can breathe a sigh of relief and kick your heels up. LOL JKS this cake is more difficult than that. Now it’s time to make the lemon-curd filling. Do this now because it needs to cool before you can fill the cake with it. It’s seriously delicious, and I recommend this recipe to top pancakes/french toast or use in lemon meringue pie or lemon slice. It’s pure noms. I doubled this recipe so I had bucketloads in the cake and some left over.
Lemon Curd Filling
3 large egg yolks, strained
Zest of 1/2 lemon
1/4 cup lemon juice
6 tablespoons sugar
4 tablespoons unsalted butter, cold, cut into pieces
1. Combine yolks, lemon zest, lemon juice, and sugar in a small saucepan. Whisk to combine. Set over medium heat, and stir constantly with a spoon or spatula, making sure to stir sides and bottom of pan (burnt curd is a bitch to get off your saucepans). Cook until mixture is thick enough to coat back of wooden spoon, 5 to 7 minutes.
2. Remove saucepan from heat. Add butter, one piece at a time, stirring with the wooden spoon until consistency is smooth.
3. Transfer mixture to a medium bowl. Lay a sheet of glad wrap directly on the surface of the curd to avoid a skin from forming; wrap tightly. Let cool then refrigerate until firm and chilled.
Ok, so now you’ve got your first set of elements done you can go and watch some True Blood for a few hours. Alexander Skarsgard will help you pass your time. Once your cakes and curd are totally cool you can begin making your frosting. It’s really, really, lemony sweet. You can add the yellow food dye or not, I did just to make it look more like a happy sunshine cake of love.
Lemon Frosting
250g soft unsalted butter
2 teaspoons lemon zest
5 cups icing sugar
60 ml fresh lemon juice
6 tablespoons whipping cream
1/2 teaspoon pure lemon extract
yellow food dye
1. Cream butter and lemon zest in bowl of electric mixer, about 3 minutes if you make sure your butter is really soft creaming it shouldn’t be difficult.
2. Slowly add icing sugar, mixing on low speed for about 2 minutes. Add remaining ingredients and beat on med-high for 3-4 minutes until very fluffy. If using food dye add it now and beat until it’s evenly distributed and the frosting is smooth and creamy.
Cake of deliciousness, assemble! Assembly really isn’t as tricky as you might think, it’s fairly straight forward actually.
1. Fill a piping bag with some of your lemon frosting.
2. Place a layer of lemon-blueberry cake with the bottom side facing down, so it’s flat.
3. Using your piping bag, pipe a layer of frosting around the edges of the cake, this will act as a dam so the lemon curd stays in place.
4. Spoon half of the lemon curd onto the cake and spread evenly. Try not to eat it, I know it’s delicious, but it needs to be in the cake.

5. Gently place you vanilla layer on top of this, making sure it’s in line and repeat. Then place your remaining blueberry layer of top of this, except this time invert the cake so the even bottom side is facing up.

6. Generously cover the outside of your cake with the lemon frosting. Use a soft spatula to spread, then when you’re happy with the thickness and evenness of your frosting, use a palette knife or butter knife dipped in hot water to smooth it all out.
7. At this point, use a spatula or large flat knife to transfer your cake onto whatever plate you plan on serving it on. This process really needs two people, you don’t want your cake hitting the dust now! …Then again it would probably still taste amaing off the floor…
8. Now you can add whatever decorations you like. It’s best to do something around the bottom edge to hide where it’s difficult to ice. I used a plain round nozzle of my piping bag to create little balls around the bottom edge of my cake. You can try you hand at shells or even just pipe a ring around the bottom.
9. For the top of my cake, I used a flat tip and made little ribbons which were cute, I thought. You could pretty much do anything, including writing ‘Happy Birthday’ or profanities on the top of your cake.
I refrigerated mine overnight so the frosting firmed up and the layers set nicely, which made it easier to cut. Voila! Your masterpiece is complete!
