• 1 teaspoon pure vanilla extract

• 1/4 teaspoon salt

Salted Caramel

• 1 cup (200g) granulated sugar
• 6 Tablespoons (90g) salted butter, room temperature cut up into 6 pieces

• 1 teaspoon salt

For Assembly

• 1/2 cup (50g) chopped pecans

Here are the instructions you need to follow:

1. Prepare the burnt sugar syrup first so it has time to cool. Make sure you have boiling water at the ready. For the burnt sugar syrup, place sugar in a medium saucepan over medium heat. Best to use a 3 quart heavy-bottomed quality saucepan. Stirring constantly with a wooden spoon, cook until the sugar has completely melted and is amber brown, about 8-10 minutes. If the sugar is clumpy, break up the lumps with your wooden spoon. A candy thermometer is not necessary, but if you’re using one, the sugar temperature should reach about 300°F (149°C) when it’s ready. Turn the heat to low and very carefully and slowly drizzle in the boiling water, a little at a time. Stir after each addition and stand back, as the mixture will rapidly sizzle and bubble. After all of the boiling water is stirred in, stir and cook the sugar syrup for 3 more minutes on low. Turn off the heat and let it cool completely, overnight preferred. It’s imperative that the sugar syrup is completely cool. You will have about 1 cup of syrup.
2. Preheat oven to 350°F (177°C). Grease two 9-inch cake pans, line with parchment paper, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans.
3. Whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
4. Using a handheld or stand mixer fitted with a whisk attachment, beat the butter and sugar together on high speed until creamed, about 2 minutes. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. With the mixer running on medium speed, pour in 1/2 cup of the cooled burnt sugar syrup. Beat until combined. Scrape down the sides and up the bottom of the bowl as needed. Beat in the egg whites, sour cream, and vanilla extract. With the mixer on low speed, add the dry ingredients just until combined. With the mixer still running on low, slowly pour in the milk until combined. Do not over-mix. The batter will be slightly thick.
5. Pour batter evenly into prepared cake pans. Bake for 23-25 minutes or until the cakes are baked through. As a result of the burnt sugar syrup cooking inside the cake batter, the cakes brown nicely on top and on the sides. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it is done. Allow cakes to cool completely in the pans set on a wire rack.
6. For the Salted Caramel:
   1. Heat granulated sugar in a medium heavy-duty saucepan over medium heat, stirring constantly with a high heat resistant rubber spatula or wooden spoon. Sugar will form clumps and eventually melt into a thick brown, amber-colored liquid as you continue to stir. Be careful not to burn.
   2. Once sugar is completely melted, immediately stir in the butter until melted and combined. Be careful in this step because the caramel will bubble rapidly when the butter is added. If you notice the butter separating or if the sugar clumps up, remove from heat and vigorously whisk to combine it again. (If you’re nervous for splatter, wear kitchen gloves. Keep whisking until it comes back together, even if it takes 3-4 minutes. It will eventually– just keep whisking. Return to heat when it’s combined again.)
   3. After the butter has melted and combined with the caramelized sugar, cook for 1 minute without stirring.
   4. Very slowly stir in 1/2 cup of heavy cream. Since the heavy cream is colder than the hot caramel, the mixture will rapidly bubble when added. After all the heavy cream has been added, stop stirring and allow to boil for 1 minute. It will rise in the pan as it boils.
   5. Remove from heat and stir in the salt. Allow to slightly cool down before using. Caramel thickens as it cools.
   6. Cover tightly and store for up to 1 month in the refrigerator. Caramel solidifies in the refrigerator. Reheat in the microwave or on the stove to desired consistency.
7. The salted caramel adds necessary flavor. We’ll use it as a filling and garnish. When ready to use in step 9, make sure the salted caramel isn’t too hot anymore. If it’s too hot, it will melt the frosting. If it’s too cool, it won’t drizzle. Let it cool for at least 30 minutes before using. If you prepared the salted caramel ahead of time and it became too cool or too thick, microwave it for 5-10 seconds or JUST until it’s drizzle-able again. (It won’t be too hot at this point.)
8. Make the frosting: In a large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 1-2 minutes. Add confectioners’ sugar, remaining 1/2 cup of cooled burnt sugar syrup, vanilla extract, milk/cream, and salt. Beat on low speed for 30 seconds, then increase to high speed and beat until completely combined, about 2 minutes. Add more confectioners’ sugar if frosting is too thin or more milk/cream if frosting is too thick. Taste. Add more salt if desired. (I usually use 1/2 teaspoon of salt total. I like this frosting salty/sweet.)
9. Assemble and frost: First, using a large serrated knife or cake leveler, slice a thin layer off the tops of the cakes to create a flat surface. Discard (or crumble over ice cream!). If you have any leftover burnt sugar syrup, drizzle over leveled cakes. I usually don’t have any leftover, but this is a great place to use any last drops if you have some. Place 1 cake layer on your cake stand or serving plate. Using a large icing spatula, evenly cover the top with frosting. Drizzle 1/4 cup of salted caramel on top of the frosting. Top with 2nd cake layer. Refrigerate the cake for at least 30-45 minutes before finishing the frosting and garnish. The caramel inside the cake must “set.” After chilling in the refrigerator, spread the remaining frosting all over the top and sides. Run a bench scraper around the cake to smooth out the sides, if desired. Garnish with toasted pecans and more salted caramel. Slice and serve.
10. Cover leftover cake tightly and store in the refrigerator for up to 5 days.
