Ingredients

Custard:

• 4 egg yolks
• ½ cup white sugar
• ¼ tsp salt
• ⅓ cup all-purpose flour
• 1 Tbs all-purpose flour
• 2 cups milk
• 1 Tbs banana liqueur (optional)
• ½ tsp vanilla extract
• 1 Tbs cold butter

Pudding:

• 3 very ripe bananas, or more to taste, sliced
• 1 ½ tsp freshly squeezed lemon juice
• 1 (12 oz) pkg miniature vanilla wafers

Meringue Topping:

• 4 egg whites
• ⅛ tsp cream of tartar
• 2 Tbs white sugar

Directions

1. Separate eggs, placing the whites in the bowl of a stand mixer and the yolks into a saucepan.
2. Prepare the custard: Add sugar, salt, and 1/3 cup plus 1 tablespoon flour to the yolks. Splash in about 1/4 of the milk and start blending mixture with a whisk. Pour in remaining milk and whisk until smooth.
3. Cook and stir mixture over medium heat until hot to the touch, occasionally dipping your finger in to test. Whisk constantly until custard is thick enough to form ribbons.
4. Remove custard from heat and add banana liqueur, vanilla, then cold butter. Whisk until butter dissolves. Set custard aside.
5. Preheat the oven to 400 degrees.
6. Begin to assemble the pudding: Toss banana slices with lemon juice.
7. Spread 1/4 of the custard over the bottom of a baking dish. Add a single layer of vanilla wafers. Cover with 1/2 of the bananas and spread 1/2 of the remaining custard on top. Add another layer of vanilla wafers, using slightly fewer this time. Top with remaining bananas and custard. Smooth the top and tap dish against the counter to settle the pudding.
8. Make the meringue topping: Add cream of tartar to the egg whites. Beat using the whisk attachment until foamy. Gradually add sugar and beat until stiff, but not dry, peaks form. Spread meringue over the pudding using a soft spatula, creating ridges for contrast.
9. Bake in the preheated oven until meringue is nicely browned, 7 to 10 minutes. Serve warm or chilled.
