Spring is here! I have been enjoying the sunshine and craving something lemon and blueberry. Don’t you think lemon and blueberry make the perfect combination? The lemon curd filling is perfectly tart and goes so well with the blueberries.
After several failed attempts, I finally was able to find a recipe that ensured my blueberries wouldn’t sink to the bottom. The first try was a mess. The blueberries sank to the bottom and turned the cake purple. The cake wouldn’t stay together. Although it was delicious, it was not presentable! The second try was with a cake mix. This turned out a little better, but still even though I covered the blueberries in flour, they would not stay put! So the third recipe I tried was VERY thick batter! This seemed to do the trick!
The lemon curd was fairly easy to make and delicious!!
How to Zest a Lemon
The Most Important Rule of Zesting
No matter which type of citrus you’re working with or method you use, there is one universal rule that will always apply: Remove just the thin, colored skin, or zest, of the fruit. Always leave behind the soft, white pith that lies underneath. The pith has a bitter, unappealing taste that you simply don’t want to include.
Removing just the right amount of zest without picking up any of the pith can be tricky, but it gets easier the more times you do it. It depends on the type of tool you’re using, as well as the amount of pressure you apply.
Using a vegetable peeler: Using moderate pressure, so as not to remove any pith, drag the peeler down the citrus fruit, from top to bottom, or around the fruit. This makes large pieces of zest, perfect for infusing oils or sugar syrup. For smaller pieces of zest, slice into thin strips or mince into pieces with a knife.
How to Dam a Cake for filling
- Take some of your frosting and mix it with some more powdered sugar until it is thick enough to form by hand but still thin enough to pipe through a large round tip or coupler.
- As you assemble the layers, pipe around the edge with the thickened frosting.
- This will create a dam to hold your filling in.
- Spread the filling to be level with the top of the dam. In this picture I am filling with a cookies and cream filling with a chocolate buttercream dam.
- Now you are ready to stack the next layer on top.
- The tips I will give you for making this cake:
- Coat the blueberries in flour before folding them into the batter, and use a thick cake batter.
- Make a dam with stiff frosting to hold in the lemon curd (if you don’t do this, the lemon curd will seep out the edges and bulge out of the sides of the cake. I learned the hard way!) .
- Make the Lemon curd the day before and let it cool over night.
- 1 cup (230g) unsalted butter, softened to room temperature
- 1 and 1/4 cups (250g) granulated sugar
- 1/2 cup (100g) light brown sugar
- 4 large eggs, at room temperature
- 1 Tablespoon vanilla extract
- 3 cups (375g) all-purpose flour, careful not to over measure
- 1 Tablespoon baking powder
- 1/2 teaspoon salt
- 1 cup (240ml) buttermilk
- zest + juice of 3 medium lemons
- 1 and 1/2 cups blueberries, fresh (258g) or non-thawed frozen (275g)
- 1 Tablespoon all-purpose flour
Lemon Blueberry Cake Directions

Assembly of cake
- Spread thin dollop of frosting on an 8-inch thin cake board or cake plate.
- Transfer 1 cake layer to board, face up.
- Create a dam around the perimeter of the layer using frosting in a pastry bag fitted with a coupler, then spread lemon curd (apprx 1 cup) inside the dam–this prevents the curd from reaching out over edges.
- Top with second layer, face-up; repeat frosting around perimeter and lemon curd filling.
- Top with third cake layer, face-down (brown smooth side up).
- Spread thin layer (crumb coat) of over top and sides of cake, using offset palette knife and bench scraper for smooth finish.
