1-First Step: Gather and Prep Ingredients Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper. In a large bowl, whisk together 2 cups flour, 1 cup sugar, 1 tsp baking powder, and 1/4 tsp salt. This dry mix sets the foundation for your crunchy vanilla biscotti recipe. Mise en place saves time for busy schedules.

2-Second Step: Mix Wet Ingredients In a separate bowl, beat 3 eggs with 1 tbsp vanilla extract and 1/4 cup oil until smooth, about 2 minutes. For vegan adaptation, use flax eggs here. Pour wet into dry, stirring until a sticky dough forms. Avoid overmixing to keep texture light.

3-Third Step: Shape the Logs Divide dough in half. On the prepared sheet, shape each into a 9-inch log, about 2 inches wide. Space them 4 inches apart. Wet hands help with handling. For gluten-free, chill dough 10 minutes first. Bake 25-30 minutes until golden and firm.

4-Fourth Step: Cool and Slice Remove from oven, cool logs 10 minutes on sheet. Transfer to a wire rack for 20 more minutes. Using a serrated knife, slice diagonally into 1/2-inch thick pieces. This angle maximizes surface for crunch. Aim for even cuts to bake uniformly.

5-Fifth Step: Second Bake for Crunch Lower oven to 325°F (165°C). Arrange slices cut-side down on the sheet. Bake 10-15 minutes, flip, then bake another 10-15 minutes until dry and crisp. Watch closely to avoid over-browning. Total second bake: 20-30 minutes. Cool completely on racks; they harden as they sit.

6-Final Step: Finishing Touches and Serving Once cool, store or enjoy. Dunk in coffee or tea. This american style vanilla biscotti recipe shines plain or with mix-ins like almonds. Total time: 1.5 hours active and baking. Perfect for batch prepping.
