I love this Banana Pudding Pie with Speculaas Crust. It is banana pudding all grown up. Speculaas, also called speculoos, also called biscoff, are spicy shortcrust cookies. If you’ve had cookie butter you’ve tasted the same flavor. They are caramelized, spicy, crunchy, and addictive. After much research (ahem) my favorite is the Lotus Biscoff brand. This spicy pie crust adds a great dimension to this creamy, meringue topped banana pudding. It also goes great with chocolate pies. If you’re more of a traditionalist you could make the shell with vanilla wafers. The riper the bananas the sweeter they are, but you don’t want them brown or too mushy to slice. A thermometer really helps to check the temperature of your pudding to make sure it will set, but you can also eyeball it if you don’t have one.
