2. Using an electric mixer on high speed, beat butter and honey until light and fluffy, about 4 minutes. Mix in egg, then flour, baking powder, salt, and walnuts just to blend.
3. Preheat oven to 350°. Whisk eggs and 1 teaspoon water in a small bowl and brush 1 side of brioche slices with egg wash. Place on a rimmed baking sheet and spread each slice with about 2 tablespoons walnut creme. Top with figs, cut side up. Brush figs with butter and drizzle with honey.
