My Mom'S Almond Cake - cooking recipe

Ingredients

1 cup unsalted butter, plus more (room temp)
unsalted butter, for buttering pan
2 cups sifted all-purpose flour, plus more
all-purpose flour, for prepping pan(s)
1/2 teaspoon salt
1 1/2 cups granulated sugar
1 (7 ounce) package almond paste
4 egg yolks, at room temp
1 teaspoon almond extract
1 cup sour cream
1 teaspoon baking soda
powdered sugar, for sifting over cake

Preparation

Preheat oven to 325 degrees.
Butter sides and bottom of pan(s) and flour them as well.
Place pan(s) in freezer (i've done this and also skipped it, works either way, i feel).
Sift flour and salt into a small bowl. Set aside.
In a mixer with a paddle, beat butter and sugar at hight til fluffy (5 min).
Add almond paste, one chunk at a time and beat at medium speed for 8 minutes.
Beat in egg yolks, one at a time.
Beat in almond extract.
Mix baking soda and sour cream together and add to butter mixture.
Reduce speed to low and add flour mixture, turn off when just blended.
Divide among the two 8 inch pans or 1 9 inch pan.
Bake about 35-40 minutes and start checking. My oven is really hot so it is usually done, but my mom's oven takes at least an hour to bake.
Cool in pans on wire rack.
Take out of pans, store in covered tins or sealed rubbermaid containers -- get better with time.
When ready to serve, dust with powdered sugar.
