🍪 How to Make Peanut Butter Spider Cookies
Step 1: Preheat & Prepare
🔹 Preheat oven to 350°F (175°C).
🔹 Line a baking sheet with parchment paper.
Step 2: Make the Cookie Dough
🔹 In a large bowl, beat butter, peanut butter, granulated sugar, and brown sugar until light and fluffy.
🔹 Add egg and vanilla extract, mixing until smooth.
🔹 In a separate bowl, whisk together flour, baking soda, baking powder, and salt.
🔹 Gradually mix the dry ingredients into the wet ingredients until a dough forms.
Step 3: Shape & Bake
🔹 Roll the dough into 1-inch balls and place on the prepared baking sheet.
🔹 Flatten each ball slightly with a fork.
🔹 Bake for 10-12 minutes, until edges are lightly golden.
🔹 Remove from oven and immediately press a peanut butter cup or truffle into the center of each cookie.
Step 4: Decorate the Spiders
🔹 Let the cookies cool for 5 minutes, then carefully transfer them to a wire rack.
🔹 Melt chocolate and use a piping bag (or a ziplock bag with the corner snipped) to draw spider legs around the truffle or peanut butter cup.
🔹 Attach candy eyes with a small dot of melted chocolate.
Step 5: Let Set & Enjoy!
🔹 Allow the chocolate to set for about 15 minutes before serving.
