Just before I started my blog, Brooklyn’s favorite pie shop, Four & Twenty Blackbirds, released a recipe for their Black Bottom Oatmeal Pie and everyone in the food world lost their minds over it. And for good reason. That pie is an old fashioned favorite: essentially a pecan pie with toasted oats instead of nuts, all suspended over a puddle of dark chocolate ganache—a triumph, if you ask me.
But, as you have probably noticed, I cannot leave well enough alone. I can’t just leave a recipe the way it is. I can’t! I’ve been looking at this perfect pie for six Thanksgivings thinking “but what if you made it with caramel?”
Well, I finally got myself together and did just that. I made the pie with luxurious homemade caramel instead of the usual invert sugars, adjusting for time and texture, and it came out magnificently. Now I just wish I hadn’t waited six whole freaking years to experience this rich, buttery, oat-studded caramel & dark chocolate masterpiece. I mean, I know I’ve made lots of other delicious things, but my goodness, I need to make up for lost time with this one.
As with so many pies, this one isn’t complicated, but it has a bunch of steps and does take time. You’ve got to partially blind bake the crust, and then there’s the whole making a caramel oatmeal filling and layering it over chocolate bit, but I promise you these are all simple steps, and if you follow them one by one and give yourself some grace and time, you will be rewarded. Oh, will you ever.
The balance of chocolate and caramel and chewy oats and flaky crust? It’s a triumph, if you ask me.
Black Bottom Caramel Oatmeal Pie
adapted from Four & Twenty Blackbirds
makes 1 pie
1/2 batch All-Butter Pie Dough (or other good single crust recipe)
Caramel Oatmeal Filling:
1 1/2 cups rolled oats (toast)
1 cup granulated sugar
1 teaspoon Kosher or sea salt
1/2 cup (1 stick) unsalted butter, cut into pieces
1 cup heavy cream, divided
2 tablespoons light corn syrup (or maple syrup or mild honey)
1 teaspoon pure vanilla extract
1 teaspoon apple cider vinegar
2 large eggs, lightly beaten, room temperature
Dark Chocolate Ganache (Black Bottom):
5 ounces bittersweet chocolate, chopped
5 tablespoons heavy cream
confectioner’s sugar, if desired
Place oven racks in the upper and lower positions. Preheat oven to 375F.
Partially blind bake the pie crust. On a floured surface, roll out pie dough to a 12" diameter. Fit into a deep 9-inch pie plate and trim the overhang to 1/2-inch. Crimp the edges and freeze for 30 minutes or refrigerate for an hour.
Remove pie crust from the freezer. Line frozen crust with a big piece of parchment. Fill the center with pie weights (or dried beans or rice).
Place the prepared pie crust on a rimmed baking sheet and bake for 20-25 minutes, or until pie crust has “set” and is starting to turn golden in places, but is far from done. Use parchment to lift out pie weights. Prick the bottom several times with the tines of a fork. Return crust to the oven for 10 minutes.
Make the caramel oatmeal filling. Place oats on a dry rimmed sheet pan. Toast in the oven for 5-7 minutes, until fragrant. Remove and let cool.
Make the caramel. Place a medium heavy-bottomed pot on the stove. Add sugar, salt, butter, 1/2 cup cream, and corn syrup to the pot. Do not stir or jostle in any way! Bring to a boil over medium heat and let cook for 10 minutes, until dark all over but not burnt. Remove from heat and *carefully* whisk in remaining 1/2 cup cream, followed by vanilla and vinegar. Let caramel cool 20 minutes.
Add oats to a mixing bowl and pour caramel over the top. Stir together. Whisk in eggs. Set aside.
Make the dark chocolate ganache (black bottom). Place bittersweet chocolate in a small bowl. Pour heavy cream into a small saucepan over medium heat. When it just barely starts to boil, remove it from the heat and pour the cream over the chocolate. Once the chocolate looks soft, stir it together with a fork until you have a smooth chocolate sauce.
Spread ganache into the bottom of the pie crust. Top with caramel oatmeal filling. Bake pie on the bottom rack for 25 minutes, then move to the top rack for another 20-25 minutes, until puffed and slightly jiggly in the center. If crust is darkening too quickly at any point, tent with foil.
Let pie cool completely before serving, with a dusting of confectioner’s sugar, if desired.
Leftover pie will keep covered at room temperature for up to two days or in the refrigerator for three.
