Making a layered custard with raisins and Oreo crumbs? Follow these tips to make sure your layered custard turns out flawless.
The Food Science of Moisture Migration
In an Oreo custard dessert, moisture will diffuse from a region of high water activity (Aw) to one of low water activity until there is equilibrium. This means that the Oreo cookie crumbs would absorb moisture from the custard, making them less crunchy and more soggy.
The Fat Barrier Technique
For an Oreo custard dessert, the coating of the Oreo crumbs with melted butter or cocoa butter provides a thin hydrophobic barrier, thus slowing down the absorption process. This could help maintain the crispiness of the wafer layers, similar to that of protected wafers used in commercial confectionery.
Perfecting Your Custard Base First
For an Oreo custard dessert, you need to cook it gently to 170-175 degrees F, to temper the eggs gradually, and to mix sugar with the yolks to prevent them from curdling. You also need to press the plastic wrap directly onto the surface to avoid the skin.
The "À La Minute" Rule for Maximum Crunch
For an Oreo custard dessert, to keep Oreo bits separate until serving time, the bits should be added to the mix just seconds before serving to limit their exposure to moisture and therefore maintain their crisp, crunchy consistency during the best contrast.
Frequently Asked Questions
Can I add Oreos directly into hot custard without them getting soggy? 
It is best to refrain from adding Oreos to hot custard. To make a crunchy Oreo custard, it is best to allow the custard to cool down and then add Oreo bits to limit the amount of moisture that can be absorbed.
Why does my custard turn rubbery instead of creamy?
Rubbery custard is produced when the eggs are overcooked or heated at too high a temperature. To make Oreo creamy custard bites, the custard has to be cooked gently and not heated beyond 175 degrees F in order to retain its creamy texture.
How far in advance can I prep the Oreo topping?
Oreo topping can be crushed up and saved in an airtight container for a day or two. To make the crunchiest Oreo creamy custard bits, it is best to add them right before serving.
