  • Electric Mixer (Stand or Hand-Held)


  • 1 cup unsalted butter, softened to room temperature
  • cup granulated sugar
  • cup light brown sugar, lightly packed
  • 1 tbsp vanilla extract
  • 2 large eggs, room temperature
  • 2 ½ cups all-purpose flour, spooned and leveled
  • 1 ¼ tsp baking powder
  • 1 tsp coarse Kosher salt (if using table salt, use half the amount)
  • 1 ½ cups mini Cadbury eggs, roughly chopped


  • Preheat the oven to 350F.
    Line a 9x13 baking pan with a piece of parchment/baking paper and snip the corners so the paper fits down into the pan. Alternatively, you can use aluminum foil, and spray the foil thoroughly with non-stick spray.
  • In the bowl of your stand mixer fitted with the paddle attachment (or using a bowl and hand-held electric mixer), beat the softened butter, granulated sugar and brown sugar until light and fluffy, about 3 minutes.
  • Add the vanilla extract, and mix in the eggs, one at a time, just until combined.
  • In a separate bowl, whisk together the flour, baking powder and salt. Add the dry ingredients and mix the dough on low, just until moistened. The dough will be very thick.
  • Pile the dough into the prepared pan. Since the dough is so thick and sticky, it can be a little tricky to spread it out. The best way is to butter your hands or a spatula and just push the dough out to the edges of the pan as evenly as you can.
  • Scatter the chopped Cadbury eggs over the dough, and lightly press them into the dough.
  • Bake the cookie bars on the center oven rack for about 20-22 minutes, just until the edges are set and every so slightly browned, but the center still looks a little underdone. Be careful not to over-bake these bars, or they will end up dry. They will continue to bake and set in the hot pan after you take them out of the oven. It's normal for the center of the bars to settle and sink down a little as it cools.
  • Set the pan on a cooling rack and cool completely before cutting into bars.


Leftover blondies should be stored in an airtight container at room temperature for up to 3 days, or wrapped well and frozen for 3-6 months.
