Heat your cooker by preheating oven to 350°F first – helps warm up the space if you wanna bake bits afterward.
Cream together the unsalted butter and sugar until it’s all light and fluffy, use a mixer or strong arm.
Add eggs one at a time so the batter stays smooth, then stir in that vanilla extract.
Mix the flour, baking powder, and kosher salt separately so you don’t get clumps.
Alternate mixing dry ingredients with milk into the wet batter, just until combined or you’ll risk a tough cake.
For the crumble, mix brown sugar and extra flour chunks for that sweet crunch topping.
Pour batter into a greased pan, sprinkle crumble evenly all over the top.
Cook in pressure cooker using a trivet and water to get that broth depth; use quick release once cued to keep the tender pull perfect. Let cake cool after cooking so it sets up nice and easy to slice.
Notes
This cake is designed to remain moist when cooked in a pressure cooker. Remember to rely on it fully to avoid excessive dryness.
