What Are Peanut Butter Spider Cookies?
How They Differ from Traditional Peanut Butter Blossom Cookies
Traditional peanut butter blossoms use chocolate kisses pressed into warm cookies. In contrast, Peanut Butter Spider Cookies use mini Reese’s Peanut Butter Cups and chocolate decorations to create playful spider shapes.
Why Mini Reese’s Peanut Butter Cups Make the Perfect Spider Body
Mini peanut butter cups have the ideal shape for spider bodies. They also pair perfectly with the peanut butter cookie base. Because of this, every bite delivers classic peanut butter and chocolate flavor.
Ingredients You’ll Need
Ingredients for the Peanut Butter Cookie Dough
- ½ cup unsalted butter, room temperature
- ½ cup brown sugar
- ⅓ cup granulated sugar
- ¾ cup creamy peanut butter
- 1 large egg
- 1 teaspoon vanilla extract
- 1½ cups all purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- Granulated sugar for rolling
Ingredients for the Spider Decorations
- 24 mini Reese’s Peanut Butter Cups, unwrapped
- ½ cup semi sweet chocolate chips
- ½ teaspoon neutral oil, optional
- Candy eyeballs
Best Peanut Butter to Use for This Recipe
Use regular creamy peanut butter with stabilizers. Natural peanut butter often separates and changes the cookie texture. Therefore, it does not work as well for Peanut Butter Spider Cookies.
How to Make Peanut Butter Spider Cookies
Step 1: Freeze the Mini Peanut Butter Cups
First, unwrap the mini peanut butter cups and place them in the freezer. Then preheat the oven to 350°F (175°C).
Step 2: Prepare the Peanut Butter Cookie Dough
Beat the butter, brown sugar, and granulated sugar until smooth and fluffy. Next, mix in the peanut butter, egg, and vanilla.
Add the flour, baking soda, baking powder, and salt. Then mix only until everything comes together.
Step 3: Shape and Roll the Cookie Dough
Shape the dough into tablespoon sized balls. After that, roll each ball in granulated sugar.
Place them on a lined baking sheet about 2 to 3 inches apart.
Step 4: Bake Until Lightly Golden and Cracked
Bake for 8 to 11 minutes. The edges should look lightly browned and slightly cracked.
Step 5: Press in the Frozen Peanut Butter Cups
Immediately press one frozen peanut butter cup into the center of each cookie.
Step 6: Cool the Cookies Completely
Allow the cookies to cool on the baking sheet for 15 to 20 minutes. Then transfer them carefully to a wire rack.
Step 7: Pipe the Chocolate Spider Legs
Melt the chocolate chips in short intervals, stirring often.
If needed, stir in a small amount of neutral oil. Next, transfer the melted chocolate to a piping bag or plastic bag.
Pipe four legs on each side of every peanut butter cup.
Step 8: Attach the Candy Eyes and Let Set
Use a small dab of melted chocolate to attach the candy eyes.
Then let the chocolate set completely before serving.
Expert Tips for Perfect Spider Cookies
Why Freezing the Peanut Butter Cups Matters
Frozen peanut butter cups hold their shape much better. As a result, they stay neat when pressed into warm cookies.
How to Keep Cookies Uniform for Even Baking
Use a cookie scoop or measuring spoon. This helps every cookie bake evenly.
Knowing When the Cookies Are Done
Look for lightly cracked edges and set sides. The centers may seem slightly soft. However, they continue cooking while cooling.
Preventing Peanut Butter Cups from Sinking
Always cool the cookies on the baking sheet first. Otherwise, the peanut butter cups can sink into the cookies.
Making Melted Chocolate Easier to Pipe
If the chocolate feels too thick, stir in a small amount of neutral oil. Then it will pipe much more smoothly.
Recipe Variations and Decorating Ideas
Different Candy Eye Options
Use large candy eyes for a goofy look. Alternatively, use mini candy eyes for a more realistic spider appearance.
Using White or Dark Chocolate for Spider Legs
White chocolate creates a fun contrast. Meanwhile, dark chocolate gives the spiders a bolder Halloween look.
Creating Other Halloween-Themed Designs
You can turn the cookies into pumpkins, monsters, or friendly bats. Therefore, this recipe offers plenty of decorating possibilities.
Storage and Make-Ahead Tips
How to Store Peanut Butter Spider Cookies
Store Peanut Butter Spider Cookies in an airtight container at room temperature for up to 3 days.
Keeping Cookies Fresh for Halloween Parties
If stacking cookies, place parchment paper between layers. This helps protect the spider decorations.
Freezing Unbaked Cookie Dough
Shape the dough balls but do not roll them in sugar.
Freeze them on a baking sheet first. Then transfer them to a freezer safe container.
Freezing Fully Baked Cookies
Allow the cookies to cool completely. Then freeze them in an airtight container for up to 3 months.
Common Mistakes to Avoid
Using Natural Peanut Butter
Natural peanut butter often creates dry or uneven cookies. Therefore, stick with regular creamy peanut butter.
Overmixing the Dough
Mix only until combined. Otherwise, the cookies may become dense.
Overbaking the Cookies
The cookies should remain soft in the center. So remove them once the edges lightly brown.
Decorating Before the Cookies Have Cooled
Warm cookies can melt the decorations. Instead, wait until they cool properly.
