Lightly toast the unsweetened coconut in a dry pan for 2-3 minutes before coating to intensify flavor and create a crispier, more golden exterior that won't taste bland.

Gently warm the raspberry jam before dipping to make it flow smoothly and coat evenly, preventing clumpy patches and ensuring a beautiful, uniform lamington finish.

Refrigerate brownies for 15-20 minutes after the jam layer and before the coconut coating to help both layers set properly and prevent them from sliding off.

Use room-temperature heavy cream when mixing with jam for a smoother, more cohesive coating that adheres better to the brownie than cold cream would.

Remove brownies 1-2 minutes before the package suggests when using box mix, as they'll continue cooking slightly and the lamington layers will add density—keeping them fudgy inside.
