Mrs. P's Biscotti

Ingredients

• 1 cup white sugar
• 0.25 cups softened butter
• 3 eggs
• 1 egg yolk
• 1.5 teaspoons vanilla extract
• 2.5 cups all-purpose flour
• 2 teaspoons baking powder

Instructions

1. 1

   Preheat oven to 350 degrees F (175 degrees C). Line a baking sheet with parchment.

2. 2

   Beat sugar and butter together in a large bowl with an electric mixer until light and fluffy; beat in eggs, egg yolk, and vanilla extract. Whisk flour and baking powder together in a bowl. Stir flour mixture into butter mixture to form a fairly sticky dough.

3. 3

   Divide dough in half; with wet hands, shape dough into two loaves, about 1-inch high at the center, on the prepared baking sheet.

4. 4

   Bake in the preheated oven until lightly browned, about 20 minutes; remove to cool completely on a wire rack, about 30 minutes.

5. 5

   Slice loaves into 1/2-inch slices with a serrated knife. Place cookie slices back onto lined baking sheet, cut sides up.

6. 6

   Increase oven temperature to 450 degrees F (230 degrees C).

7. 7

   Bake in the preheated oven until golden brown, turning once, 3 to 4 minutes per side.
