Preheat and prep: Preheat the oven to 325℉. Lightly butter an 8x8-inch baking dish.
~1 Tbsp. softened butter
Melt butter: Melt the butter in a microwave-safe dish in 30-second increments until melted. Set aside to cool slightly.
1/2 cup unsalted butter
Beat sugar and eggs: In the bowl of an electric mixer fitted with the paddle attachment, beat the eggs and sugar on medium-high speed for 8-10 minutes, or until very thick and light yellow. Start Timer
2 extra large eggs room temperature, 1 cup granulated white sugar
Sift dry ingredients: Meanwhile, sift the cocoa powder, flour, espresso powder, and salt together and set aside.
6 Tbsp. cocoa powder, 1 tsp. espresso powder, 1/4 cup all-purpose flour, Pinch of salt
Bring it together: When the egg and sugar mixture is ready, reduce the speed to low and add the vanilla bean paste, framboise (if using), and the cocoa powder/flour mixture. Mix only until combined. With mixer still on low, slowly pour in the cooled butter and mix again just until combined. Careful not to over mix.
1 tsp. vanilla bean paste, 1½ tsp. framboise liqueur
Prepare water bath (Bain-Marie): Pour the brownie mixture into the prepared dish and place it in a larger baking pan (I used a 9x13 pan). Add enough of the hottest tap water to the pan to come halfway up the side of the dish.
Bake: Bake for ~40-50 minutes. A toothpick inserted 2 inches from the side will come out 3/4 clean. The center will appear very under-baked; this dessert is between a brownie and a pudding. Start checking at 38–40 minutes. Brownie pudding is all about that custardy center, so it’s better to pull it a touch early than over-bake. Start Timer
Cool and serve: Allow to cool for 10-15 minutes in the water bath still, then lift it out and serve with your favorite vanilla ice cream. YUM! Start Timer
