Also, I should probably provide the disclaimer that I don't like standard peanut butter cups. Those orange-wrapped things seem to be pretty popular, but I find them greasy, overly sweet and the filling seems gritty. I write that so that you know that I may not be the best judge of character when it comes to the classic peanut butter and chocolate combo. I should mention that, not surprisingly if you read my blog, because I am evidently a pretty diehard fan, I find the peanut butter cups in Ben & Jerry's Peanut Butter Cup ice cream at least satisfactory. The chocolate is a little thicker than I suppose would be ideal, but it is in no way waxy like Reese's, and the peanut butter filling is much smoother.
So in this ice cream my favorite creamy Milk Chocolate Ice Cream base is speckled with little clumps of soft peanut butter goodness, kind of like a smooth peanut butter cup filling without the pesky too-thick, not-intense-enough-chocolate shell.
One more note: I grew up on Baskin Robbins' rich, dark chocolate ice cream with that salty, crunchy-when-frozen peanut butter swirl. This ice cream is not that. As much as I would love to recreate that, all my attempts at a peanut butter swirl have had textural issues. Also this Milk Chocolate ice cream base is more like a frosty in flavor (and texture if eaten within a few hours of churning).
Milk Chocolate Peanut Butter Ice Cream
Ice cream base adapted from Ben & Jerry's. Mix-in adapted from a peanut butter frosting recipe from King Arthur Flour. Makes slightly more than 1 quart.
Make ice cream base: Whisk together 2 whole eggs. I use my electic stand mixer with the whisk attachment. Gradually whisk in 4 tablespoons cocoa powder and 2/3 cup sugar. Scrape sides of bowl. If desired add a pinch of salt. Whisk in 1 cup whole milk, 2 cups heavy whipping cream and 1 teaspoon vanilla extract. Transfer ice cream mixture to ice cream maker. Churn according to manufacturer's instuctions.
Make peanut butter mix-ins: In same mixing bowl (no need to wash it), whisk 1/2 cup creamy salted peanut butter. For ease of mixing, room temperature peanut butter is best. As much as I hate to say it, use the commercial stuff; the natural stuff is too gritty for confectionary applications. (I have used Trader Joe's peanut butter here successfully, but who knows whether it is more natural than other grocery store's brands). Whisk in 1/4 cup confectioners (powdered) sugar. Continue to whisk until all the sugar is absorbed by the peanut butter. Then slowly whisk in 2-4 tablespoons heavy cream or half and half and a splash of vanilla extract. You want something thicker than a buttercream frosting, but slightly less thick than a cookie dough. Use a spatula to scrape peanut butter mixture out of mixing bowl and onto a work surface such as a cutting board or plate. Use clean hands to pinch off a 1/4 to a 1/2 teaspoon of the mixture at a time. Roll into balls as neatly or as roughly as you like. If time allows, transfer finished mix-ins to freezer.
One minute before the end of churning time, drop peanut butter mix-ins into the ice cream maker a few at a time. Let churn a minute to distribute. Transfer ice cream to freezer-safe containers to continue freeze time. Ice cream is generally at soft-serve texture fresh out of the machine, but will become a more scoopable ice cream after a few hours in the freezer.
