This lemon curd cake is the perfect way to celebrate summer. A moist, tender lemon layer cake with a lemon curd center is frosted with lemon buttercream frosting to create a sweet, tangy dessert full of the flavors of summer.
Preheat oven to 350℉ . Lightly grease two 9” round cake pans and set aside.
Add all of your dry ingredients to a bowl and whisk to combine them.
Next add your butter and half of the sugar to a separate bowl and mix on medium high for a minute or until the mixture is fluffy.
Add the oil and remaining sugar and mix on medium high for another minute or until it’s fluffy.
Begin adding your eggs one by one, mixing after every second egg.
Once the eggs have been incorporated add both extracts and the lemon juice, mixing to combine.
Add half of your dry ingredients and mix until just combined.
Mix in the milk and yogurt until incorporated.
Finally add your remaining dry ingredients and mix until just combined. Your batter will be wet and pudding-like.
Dive the batter between the two prepared cake pans.
Allow your cakes to bake for 30-37 minutes, or until a toothpick comes out clean. Let the cakes cool for an hour.
To make your lemon buttercream frosting, add the room temperature butter to a bowl and mix on high for two minutes until fluffy. Turn your mixer to low and add a cup of powdered sugar. Increase the speed to high and continue to add one cup of sugar at a time along with the remaining ingredients.
Mix until smooth and creamy.
To assemble your cake, pipe a circle of buttercream around the outer diameter of the first cake.
Pour lemon curd into the center and spread it out.
Place the second cake on top.
Frost the entire top and side of the cake with the lemon butter cream.

Tips
Make sure all refrigerated ingredients for both the cake and frosting are at room temperature. This allows for more complete mixing while reducing the possibility of overmixing.
Be sure your baking powder is fresh. Expired leaveners will result in a flat, dense cake.
Mix your cake batter ingredients until just combined. Overmixing creates a tough cake.
Your cake should be fully cooled before frosting. A cake that's even slightly warm will cause the frosting to thin and slide off.
Use organic lemons if possible. Regular lemons have a waxy coating to make them shelf-stable. Organic lemons don't have this.
