Place your condensed milk, cream cheese, and peanut butter. Not only those, but also the butter, vanilla, and salt inside a mixing bowl. Then, make sure to beat using an electric mixer attached with a paddle attachment. Remember, beat at medium-low speed until your mixture becomes creamy. Afterward, scrape down the bowl's sides using a rubber spatula to mix properly.
1/2 cup of condensed milk, 1 cup of creamy peanut butter, 5 tbsp of butter at room temperature, 120 grams of cream cheese, 1/4 tsp of vanilla extract, 1/4 tsp of kosher salt
