Cookie Tips
Here are some cookie tips to yield the best chocolate peanut butter cookies.
1. Use aluminum baking sheets. Aluminum baking sheets conduct heat the best and most evenly. These cookies will have those crisp outer edges and chewy centers. If you use non stick and dark of pans your cookies will cook too quickly. Also, aluminum cookie sheets have a completely flat surface with one easy to grip edge. Use parchment paper and only hand wash your baking sheets.
2. Use room temperature ingredients. This will get you the maximum fluffiness in cookie texture and crisp edges.
3. Do not over-bake the cookies. These cookies need only 9 minutes in the oven. They will have slightly puffed and gotten crisp around the edges. Once out of the oven, allow them to cool for a minute on the cookie sheets.
4. Use a cookie scoop or hand roll cookie balls. Use 2 tablespoons of cookie dough that you either roll in your hands or use a pre measured scoop out for even cookies. This will ensure even baking for all the cookies.
5. If you can’t bake one sheet at a time, then Bake cookie sheets on 1st and 3rd racks. Then rotate halfway through baking.
6. Use a hand or stand mixer to cream the wet ingredients for the best texture.
7. Weighing ingredients is the best way to yield the same results every time and have perfect bakes. Have a food scale handy, and See my recipe for metric conversions.
8. Use fresh ingredients. Expired baking soda will effect the result of the cookies and could lead to flat, thin cookies.

Halloween Candy Cookies
Halloween, aka the biggest candy day of the year, is already creeping up on us in a few short weeks. These cookies are a great way to use up all those extra peanut butter cups. Bonus, besides the candy theme, the colors of the cookies are naturally there for Halloween.
I don’t each much candy except for when Halloween hits. Since Bea and Tilly are so little but love Trick or Treating, we have so much extra Halloween Candy leftover each year. First, I shamelessly root through their buckets for the candy I like. Then I ruthlessly binge eat that candy after the kids go to bed. Ahhh, Mom life really is the best life! But In my defense, kids shouldn’t eat that much candy!
But then I put the rest of that candy to good use, like making these amazing Halloween candy cookies!

Dark Chocolate Cocoa
Anyone who knows me is aware of my dark chocolate obsession. So when I bake brownies and cookies I’m usually using dark chocolate.
So for these peanut butter cup brownie cookies I used unsweetened Dark Chocolate Cocoa powder. However, you can swap that out for any Dutch processed cocoa powder you prefer.
Dark cocoa powder shouldn’t be confused with the black cocoa powder that is used in my Snickers Poke Cake, Black Velvet Cake, and Black Cocoa cutout cookies.

Secret Ingredient Cookies
Since this cookie recipe is going up around Halloween, a mystery ingredient seemed fitting. These incredibly chewy cookies use the addition of corn starch.
Corn starch in cookies yields an especially tender cookie. It will make cookies extra soft and even chewier than ever. Cornstarch is great for any soft baked cookies using cocoa powder, like these chewy chocolate cookies. Try them in my Double Chocolate Cookies too!

The only thing spooky about these cookies is how many you’re going to end up eating!
