Salted Peanut Butter Chocolate Jars

Instructions:

1. Combine crushed pretzels, melted butter, and a pinch of salt in a small bowl.
2. Spoon 1-2 tablespoons of the pretzel mixture into the bottom of each of the 6 jars and press down firmly with a spoon to create a compact crust.
3. In a large bowl, beat the peanut butter and powdered sugar until smooth using an electric hand mixer.
4. Slowly pour in the cold heavy whipping cream and vanilla extract, whipping on high speed until stiff peaks form and the mixture is pale and fluffy.
5. Pipe the peanut butter mousse over the crust layer, filling each jar approximately two-thirds of the way.
6. Place chocolate chips in a microwave-safe bowl and pour hot heavy cream over them.
7. Let the chocolate sit for 2 minutes, then whisk in room temperature butter until the mixture is a glossy liquid.
8. Pour the ganache over the mousse layer and garnish with a pinch of flaky sea salt.
9. Chill the jars in the refrigerator for 30 minutes before serving.
