What is brown butter?
Brown butter, also known as beurre noisette, is butter that has been cooked until the milk solids caramelize, giving it a rich, nutty flavor. In these Halloween blondies, brown butter adds depth and complexity, elevating the simple treat into something extra special.
Ingredients
Gather the following ingredients to create these Halloween brown butter blondies:
- All-purpose flour - sift flour if necessary to remove any lumps
- Salt
- Butter - use unsalted butter. Cut butter into half inch chunks before browning.
- Brown sugar - use light or dark brown sugar
- Eggs - bring to room temperature before starting recipe
- Candy - use your choice of candy. I used Reese's cups, chocolate bars, M&Ms and candy corn.
- Googly eyes - use edible googly eyes
See recipe card for quantities.
Instructions
1 - Prepare baking pan
This recipe is baked in an 8x8-inch square pan. Follow the pan preparation steps below to ensure the Halloween blondies are easy to remove after baking:
- Make two strips of 8" x 14" parchment paper.
- Lightly grease the pan with melted butter or baking spray; this will help parchment adhere to the pan.
- Place one sheet of parchment over the pan and press it into the bottom and sides, creasing the paper where the edges of the pan meet.
- Lay the second sheet of parchment crossed over the first sheet and extending up the sides of the pan.
- Make sure parchment paper hangs over sides of the pan. These will act as handles to lift out the blondies
2 - Brown butter instructions
Follow the instructions below to brown your butter. This process takes several minutes, so be sure to keep a close eye on it, as the butter can burn quickly.
1 - Place chunks of butter in a saucepan over medium heat, stir occasionally. Once the butter has melted, it will begin to foam. Keep cooking and stirring. The foam will subside, and the butter will start to sizzle and bubble.
2 - The milk solids in the butter will start to brown. You’ll notice a nutty aroma and see the butter turn golden brown. Keep a close eye on it to prevent burning and continue stirring.
When the butter has turned a deep golden brown and you see browned bits (milk solids) at the bottom of the pan, remove it from heat immediately. This takes approximately 4 - 6 minutes.
3 - Pour the browned butter into a heat-resistant bowl. Let it cool at room temperature for 30 minutes before proceeding with the rest of the recipe.
3 - Blondie instructions
1 - Add brown sugar to bowl with cooled butter. Whisk until smooth.
2 - Add eggs to bowl. Whisk until smooth.
3 - Add flour and salt to bowl. Stir until smooth and no dry pieces of flour remain.
4 - Add candies of your choice (e.g. M&M's, chopped chocolate bars, etc...). Stir until evenly distributed.
5- Add half of the blondies dough to prepared baking pan. Use your hands or an offset spatula to smooth dough evenly. Place chocolate candy bars on top of dough.
6 - Add remaining blondie dough to pan. Use your hands or an offset spatula to smooth dough evenly.
7 - Add additional candies of your choice to top of dough (e.g. Reese's M&M's, chocolate bars, etc....). Press each piece gently into the dough.
