Remove cream cheese packaging and place on a microwave-safe plate. Microwave 20 to 30 seconds. Flip and microwave for another 10 to 20 seconds, or until soft but not melted.
Add softened cream cheese, brown sugar, vanilla, and salt to the bowl of a stand mixer fitted with the whisk attachment. Beat until completely smooth.
Run a spoon under hot water and dry it. Use the spoon to scoop the marshmallow creme into the mixer. Beat until fully incorporated.
With the mixer on low speed, slowly pour in the heavy cream. Once fully added, increase speed and beat until thickened and soft peaks form (see note 3). Do not over-beat.
Add mini chocolate chips and gently fold in with a spatula.
Cover and refrigerate 15 to 20 minutes. Give the dip a quick stir, then serve with your favorite dippers. Pretzels and vanilla wafers are my favorites.
Notes
Note 1: Use full-fat, brick-style cream cheese for best results.Note 2: I recommend imitation vanilla so the dip does not have an alcohol flavor since it is not baked.Note 3:Soft peaks means when you lift the beater, the cream holds its shape but gently folds over at the tip.Note 4: Great dippers include pretzels, vanilla wafers, graham crackers, strawberries, and Milano cookies.Storage: Store covered in the fridge for 2 to 4 days. If separation occurs, gently fold with a spatula to recombine. Freezing is not recommended because dairy can become grainy.
