Peppermint Mocha Biscotti

Peppermint mocha biscotti are crisp, twice-baked almond cookies studded with dark chocolate and crushed peppermint candy. The coffee flavor is subtle but real, and the peppermint comes through as a cool finish without tasting medicinal. The key is baking them twice: once as a log, then sliced and baked again until they shatter when you bite them.

Ingredients for Peppermint Mocha Biscotti

All-purpose flour and baking powder give the biscotti structure and lift. Butter and granulated sugar create richness and crispness. Eggs bind everything together. Instant espresso powder adds depth without a strong coffee taste. Vanilla extract rounds out the flavor. Sliced almonds add crunch and nuttiness. Dark chocolate chips contribute sweetness and texture. Crushed peppermint candy brings the signature peppermint flavor and a little sparkle. Salt balances everything.

Why This Peppermint Mocha Biscotti Works

The first bake creates a firm, cake-like log that holds together when sliced. The second bake dries out the slices until they are hard and crunchy enough to dunk without falling apart. This two-stage method is what makes biscotti different from regular cookies.

Espresso powder dissolves into the dough and does not bake out. It deepens the chocolate flavor and adds a bitter note that keeps the cookies from tasting too sweet. The peppermint candy is crushed coarse so you get flecks of flavor and texture rather than a uniform mint taste.

Slicing while the log is still warm but cool enough to handle keeps the edges from crumbling. The cookies finish crisping as they cool, so do not overbake them in the second round or they become hard to bite.

Mistakes To Avoid

Overmixing the dough after you add the flour makes the cookies tough and dense. Mix just until you do not see dry flour streaks, then stop. The dough should look shaggy and come together only when you shape it.

Baking the first log too long dries it out so much that it shatters when you try to slice it. The log should be set on top but still give a little when you press it. It finishes cooking as it cools.

Packing the slices too close on the sheet blocks air circulation and keeps the bottoms from crisping. Leave a half-inch gap between each piece so heat can reach all sides.

Skipping the second bake or stopping too soon leaves the centers soft. The slices should be pale golden and sound hollow when you tap them. They firm up more as they cool.

Ingredients

• 2 cups (250 grams) all-purpose flour
• 1 1/2 teaspoons baking powder
• 1/2 teaspoon salt
• 1/2 cup (113 grams) unsalted butter, room temperature
• 3/4 cup (150 grams) granulated sugar
• 2 large eggs, room temperature
• 1 teaspoon vanilla extract
• 2 teaspoons instant espresso powder
• 1 cup sliced almonds
• 3/4 cup dark chocolate chips
• 1/2 cup crushed peppermint candy

Step-by-step Instructions

1. Heat your oven to 350°F (175°C). Line an 8×4-inch loaf pan with parchment paper, leaving overhang on two sides.
2. Whisk together flour, baking powder, and salt in a small bowl.
3. Beat butter and sugar with an electric mixer on medium speed for 2 to 3 minutes until light and fluffy, scraping the bowl once halfway through.
4. Add eggs one at a time, beating for about 30 seconds after each one. Add vanilla and espresso powder and beat for 15 seconds until combined.
5. Add the flour mixture and mix on low speed for about 1 minute, just until no dry flour shows. Fold in almonds, chocolate chips, and peppermint candy with a spatula until even.
6. Scrape the dough into the prepared pan and smooth the top. Bake at 350°F (175°C) for 25 to 30 minutes until the top is set and a toothpick inserted in the center comes out with a few moist crumbs. The log should be golden on top but still yield slightly when pressed.
7. Let the log cool in the pan for 10 minutes, then lift it out using the parchment overhang and place it on a cutting board. Let it cool for another 5 minutes until it is warm but firm enough to slice without crumbling.
8. Using an offset serrated knife, slice the log into 1/2-inch-thick biscotti on a slight diagonal. Wipe the knife between cuts.
9. Place the slices upright on two baking sheets, leaving 1/2 inch between pieces. Bake at 350°F (175°C) for 12 to 15 minutes until the edges are pale golden and the bottoms are dry to the touch.
10. Flip each biscotti and bake for another 8 to 10 minutes until the other side is dry and pale golden. The biscotti should sound hollow when tapped. Transfer to a wire rack and cool completely before storing.
