1 C whole wheat flour
1/2 C old-fashioned oats
1/3 C slivered almonds
1/4 C sugar
2 t baking powder
1/2 t kosher salt
6 T chilled butter, cut into 1/2" cubes
1/2 C chilled heavy whipping cream, divided, plus more for brushing
1 t vanilla extract
4 C fresh strawberries
Preheat oven to 375. Line a baking sheet with parchment paper. Pulse flour, oats, almonds, sugar, baking powder, and salt in a food processor until finely ground. Add butter; pulse until only pea-size pieces remain. Add 1/2 C cream and 1 t vanilla. Pulse until large moist clumps form. Transfer to a work surface.
Knead until dough comes together, about 4 or 5 turns. Pat into a 4/6" rectangle. Halve lengthwise, then crosswise into thirds. Arrange on prepared baking dish. Brush with cream and sprinkle on a little bit of sugar.
Bake, rotating sheet about halfway through cooking, until golden brown around edges...or about 20 minutes.
Brush the dough with a little bit of the whipping cream.
