Lemon Pie Poke Cake

Created from recipes on Betty Crocker, Our Best Bites and my imagination. It needs a better name, though, because the cake is MUCH better than the name implies!

Tip: Bake cake/s and assemble with filling the night before, then mix the frosting and decorate the cake a few hours or so before serving.

Cake:
1 box white cake mix
1 cup all-purpose flour
1 cup granulated sugar
3/4 tsp salt
4 egg whites
1 1/3 cups water
2 Tablespoons vegetable oil
1 cup sour cream
2 tsp vanilla extract (use clear vanilla if you want a pure white cake)

Mix all dry ingredients with a whisk, then add wet ingredients. Beat for two minutes until fluffy. Bake as directed on box.** Cool 5 minutes, while mixing up filling, then poke holes (¼-inch to ½-inch in diameter) almost to bottom of cake every ½-inch or so, wiping handle of poking spoon occasionally to reduce sticking.

Lemon Filling:
1 can (14 ounces) sweetened condensed milk
¾ cup whipping cream
½ cup lemon juice
1 teaspoon lemon zest
5 drops yellow food color

In medium bowl, stir together all ingredients. Pour over warm cake; spread evenly over surface, working back and forth to fill holes. Some filling should remain on top of cake. Refrigerate 1 hour. (Double amounts if doing a layer cake - will have some left over. Great to make filled cupcakes with, as seen on Our Best Bites.)

Frosting:
6 Tablespoons flour
1 cup whole milk (can use lower-fat if desired)
1 cup butter
1 cup granulated sugar
2 teaspoons clear vanilla extract
2 teaspoons lemon extract

Whisk together flour and milk. Heat in small sauce pan on medium heat. Whisk continuously until it starts to thicken. Let it cook, while stirring until it looks like pudding before it's set (you should be able to see the bottom of the pan when you stir it). Even though it’s thick, push it through a mesh strainer (use the whisk to push it through) and then let it cool completely to room temp. Be sure it is completely cool or it will melt the butter and you’ll have runny frosting. In an electric stand mixer, beat the butter and sugar for a minute or two until well combined and fluffy. Use the whisk attachment on your stand mixer. While beating, add in the thickened milk mixture, lemon and the vanilla. Beat on the highest speed you can (without it spitting all over the kitchen) for 7-9 minutes. If needed (if it’s not velvety smooth and fluffy), beat for another few minutes. Store at room temperature until ready to frost cake. (View tutorial on Our Best Bites for great pics.)

Garnish, if desired:
Fresh strawberries
Blueberries

Garnish with fruit as desired. Store loosely covered in refrigerator.

**Can make as a thick 9x13-inch cake, or can make as a double-layer round/square with batter left over for 10 cupcakes! If doing two layers, will have to poke first layer and pour filling over, then spread extra filling on top (may want to double the filling amount depending on your preference) of that layer before placing second layer on top. Poke that layer and then pour filling over top, then refrigerate until ready to make and spread frosting as desired.
