- Unsalted Butter: Adds richness and moisture to the dough.
- Brown Sugar: Brings a soft texture and deep molasses flavor.
- Granulated Sugar: Sweetens and helps create that slight cookie crisp.

- Egg: Binds ingredients and adds structure.
- Vanilla Extract: Enhances sweetness and rounds out the flavor.
- All-Purpose Flour: The backbone of the cookie dough.
- Baking Soda: Gives the cookies a nice rise and softness.
- Baking Powder: Works with the baking soda for texture lift.
- Salt: Balances the sweetness.

Ingredient Substitutions for Dietary Needs or Pantry Gaps
If you’re short on ingredients or accommodating specific dietary needs, try these smart swaps:
- Gluten-Free Option: Use a 1:1 gluten-free flour blend (like King Arthur’s).
- Nut-Free Version: Substitute sunflower seed butter or soy butter and use a chocolate button instead of Reese’s.
- No Candy Eyes? Mini white chocolate chips with a dot of melted chocolate work great.
- No Peanut Butter Cups? Use chocolate truffles or Hershey’s Kisses for the spider body.
How to Make Peanut Butter Spider Cookies (Step-by-Step)
Follow these detailed steps for cookie success — no tricks, just treats!
- Freeze the Reese’s: Unwrap 24 mini Reese’s and place them in the freezer to keep their shape during assembly.
- Preheat Oven: Set your oven to 350°F (175°C) and line your baking sheet with a silicone mat.
- Cream Butter and Sugars: In a large bowl, beat the butter, brown sugar, and granulated sugar until light and fluffy (about 1 minute).
- Add Wet Ingredients: Mix in the peanut butter, egg, and vanilla until fully combined.
- Combine Dry Ingredients: Stir in flour, baking soda, baking powder, and salt until just mixed. Don’t overdo it.
- Shape Cookies: Scoop tablespoon-sized dough balls, roll between your palms, then coat with granulated sugar.
- Bake: Arrange cookies 2-3 inches apart and bake for 8–11 minutes, or until edges begin to crack.
- Add Reese’s: Remove from oven and gently press a frozen Reese’s into the center of each cookie. Let cool on the baking sheet for 15–20 minutes.
- Draw Legs: Melt chocolate chips in the microwave at 50% power, stirring every minute. Transfer to a squeeze bottle or sandwich bag, and pipe four legs on each side of the Reese’s.
- Attach Eyes: Dab melted chocolate on the back of the candy eyes and press onto each Reese’s. Let set completely.

Frequently Asked Questions About Peanut Butter Spider Cookies
Can I make these cookies in advance?
Yes! You can prepare the dough up to 2 days in advance and store it in the fridge. You can also bake the cookies and store them in an airtight container for up to 3 days, or freeze them for up to 3 months.
What type of peanut butter should I use?
Stick with classic creamy peanut butter like Jif or Skippy. Natural peanut butter tends to separate and will affect the texture of the dough, making it oily or too dry.
What’s the best way to melt the chocolate for spider legs?
Use a microwave-safe bowl and melt the chocolate chips at 50% power in 1-minute intervals, stirring each time until smooth. A squeeze bottle or a plastic sandwich bag with the tip cut off makes piping easy and mess-free.
How can I keep the Reese’s cups from melting too much?
Freeze the Reese’s cups while the cookies bake. Press them in gently once the cookies are out of the oven and let them cool completely before adding the legs and eyes. This prevents them from becoming too soft or losing their shape.
