Submerge each slice of chocolate babka in the custard, turning to ensure both sides are evenly coated. Let soak for 1–2 minutes per side for full absorption.

Heat 15 g (1 tbsp) of butter in a large nonstick skillet over medium heat. Working in batches, transfer custard-soaked babka slices to the skillet. Cook undisturbed until golden and custard is set on one side, approximately 3–4 minutes. Flip slices and cook an additional 3 minutes, or until firm. Repeat with 15 g (1 tbsp) butter for each batch.

While the babka cooks, whip the remaining 90 g (6 tbsp) butter in a large bowl using a handheld mixer at medium-high speed until light and fluffy, about 1–2 minutes. Add raspberry preserves and cinnamon, beating just until the mixture forms a smooth and cohesive, deep pink butter.
