|Raspberry Lemon Buttercream Cake|
Spouse and I were invited over to a friends for the evening last weekend so I threw together something for a little late evening dessert. Our friend Barb is a big lemon fan, so this cake started out as a standard lemon buttercream cake but I had a large batch of raspberry compote in the fridge to use up and with lemons and raspberries being such good flavor friends I used it to fill the layers too.
- 2 3/4 cups cake flour
- 3 tsp baking powder
- 1/4 tsp salt
- 1 cup unsalted butter, at room temperature
- 2 cups sugar
- 4 eggs at room temperature
- 2 teaspoons vanilla extract
- zest of one large lemon, finely minced
- 1 1/4 cups undiluted evaporated milk
- 2 cups fresh or frozen raspberries
- 1/3 to 1/2 cup sugar
- 2 tbsp corn starch
- aprox 1 ounce water
Slowly simmer the berries and sugar over low heat for about 10 minutes. Dissolve the corn starch in the water and slowly pour into the boiling berries stirring constantly until thickened.You may not use all of the cornstarch mixture depending upon how juicy the berries are or you may need a little more.
- 8 cups icing sugar (i.e. powdered sugar, confectioners’ sugar)
- 2 cups butter
Using an electric mixer on low, mix the butter and icing sugar together until the butter breaks up and get evenly dispersed throughout the sugar in small pieces. The mixture will still appear dry at this point. This stage ensures even distribution and prevents butter lumps in your frosting.
- 2 tsp vanilla extract
- 3 tbsp lemon juice
- zest of one lemon, finely minced
- Approximately 4-6 tbsp milk, only enough to bring the frosting to a spreadable consistency
Both of these liquid measures can be adjusted. The milk can be adjusted to make a thicker frosting by adding less or a more spreadable frosting by adding a little more. Use your own judgement here. The lemon juice can be adjusted to your own taste too.
When the icing reaches the desired consistently continue to beat it on high speed for 5 minutes to incorporate more air into the frosting to make it lighter and fluffier.
