Butterbeer Cookies — Harry Potter, Chewy, Frosted, Caramel-Drizzled

Ingredients

• Cookie — dry spooned & leveled flour

  • 2 cups All-purpose flour 250 g. Spooned and leveled — don't scoop or you'll pack 20% more flour.
  • ½ tsp Baking soda
  • ½ tsp Baking powder
  • ½ tsp Kosher salt

• Cookie — wet

  • ¾ cup Unsalted butter, softened 168 g. Out of the fridge 30 min ahead — soft enough to dent with a finger, not greasy.
  • ¾ cup Light brown sugar, packed 165 g. Mostly brown sugar = chewier cookies.
  • ¼ cup Granulated white sugar 50 g.
  • 2 Egg yolks, room temperature Yolks only — the extra fat is what makes these chewy.
  • 1 tbsp Vanilla bean paste or extract Bean paste is worth it here if you have it.
  • 1½ tsp Butter extract McCormick or LorAnn. The "butter" in butterbeer.

• Cookie — butterscotch

  • ¼ cup Butterscotch chips, melted 50 g. Melted into the dough — gives every bite butterscotch flavor.
  • ½ cup Butterscotch chips, whole 100 g. Folded in at the end for melty pockets.

• Butterscotch buttercream

  • ½ cup Unsalted butter, softened 112 g.
  • ⅛ tsp Kosher salt
  • ½ cup Butterscotch chips, melted & cooled 100 g. Slightly cooled so they don't melt the butter.
  • 1 cup Powdered sugar, sifted 130 g.
  • ¼ tsp Butter extract
  • ½ tsp Vanilla bean paste or extract

• Butterbeer caramel slow-reduced soda

  • 12 oz Flying Cauldron butterscotch beer 355 ml. Cream soda works as a swap — see notes.
  • 3 tbsp Unsalted butter, softened 42 g.
  • 3 tbsp Heavy cream, room temperature 45 ml. Room temp so it doesn't seize the caramel.
  • pinch Kosher salt

• Finishing optional

  • — White & gold nonpareil sprinkles Make them look magical. Skip if you want.

Method

1. Pre-heat & line the sheets

   T+0:00

   Heat the oven to 350°F, rack in the lower-middle position. Line two baking sheets with parchment paper. Melt the ¼ cup of butterscotch chips for the dough in a small bowl (microwave 30 sec, stir, 15 sec, stir) and set aside to cool slightly.

2. Whisk the dry ingredients

   T+0:03

   In a medium bowl, whisk the flour, baking soda, baking powder, and salt. Set aside.

3. Cream the butter & sugars

   T+0:05

   In a large bowl (or stand mixer with paddle), beat the softened butter, brown sugar, and white sugar on high speed until light and fluffy — 2 to 3 minutes. The mixture should pale visibly. Scrape the bowl once.

   

4. Add yolks, extracts, melted chips

   T+0:09

   Add the egg yolks, vanilla bean paste, butter extract, and the slightly-cooled melted butterscotch chips. Beat on medium speed until pale and fluffy, 1–2 minutes. Scrape the sides as needed.

   

5. Combine wet & dry, fold in chips

   T+0:11

   Add the dry ingredients to the wet on low speed, mixing just until combined — overmixing develops gluten and the cookies turn cakey. Fold in the ½ cup of whole butterscotch chips with a rubber spatula by hand.

   

   

6. Scoop & bake

   T+0:14

   Using a 2-tablespoon cookie scoop, portion the dough onto the prepared sheets, 2 inches apart (8–9 per sheet). Bake one sheet at a time for 10–11 minutes — edges set, centers still soft and slightly underdone. They'll firm up as they cool. About 19 cookies total.

   

7. Cool on sheet, then rack

   5 min + 25 min passive

   Let the cookies rest on the sheet for 5 minutes — they're too soft to move right out of the oven. Transfer to a wire rack and cool completely (about 25 minutes) before frosting. Frosting a warm cookie melts the buttercream into a slick.

   

8. Make the buttercream (while cookies cool)

   T+0:35

   Whip the ½ cup of softened butter with the ⅛ tsp salt on high speed until pale and fluffy — 5 to 10 minutes. Add the melted-and-cooled ½ cup butterscotch chips and beat until combined. Sift in the powdered sugar, then add the butter extract and vanilla. Beat until smooth. Cover until ready to use.

   

9. Reduce the butterbeer caramel

   15–17 min

   In a small saucepan, simmer the 12 oz of butterscotch beer over medium-low heat for 15–17 minutes — it should thicken to a syrup and turn deep golden. Don't walk away near the end; it goes from syrup to scorched fast. Off the heat, whisk in the butter, then the cream, then the pinch of salt. Return to low heat and simmer 1 minute to bring it together. Let cool to room temperature — it thickens further as it cools.

   

10. Frost, drizzle, sprinkle, serve

    T+1:25

    Frost each cooled cookie with butterscotch buttercream using a mini offset spatula — a generous swirl, not a thin scrape. Drizzle butterbeer caramel over the top with a spoon. Hit with white and gold nonpareils while the caramel is still tacky so they stick. Serve same day for the softest texture; they keep 3 days in an airtight container.
