About Brennan’s
Brennan’s version of the oatmeal custard adds a delightful twist to the classic recipe. Brennan’s is the name associated with Bernard “Barney” Brennan, an Irish baker who decided to put his own spin on this traditional dish. His innovative approach gave the dessert a unique identity, making it popular with both locals and visitors in his quaint little bakery in the heart of Dublin.
In Barney’s version, the oats were simmered until they were fluffy and tender before being gently stirred into a creamy custard base, further amplifying the oatmeal texture. This version of “Brennan’s Oatmeal Custard” significantly deviated from the traditional recipe, introducing additional layers of taste and texture.
What Is Custard?
A custard is essentially a cooked mixture of milk (or cream) and egg yolk. Its origin can be traced back to the Middle Ages when it was first used as a filling for tarts. Since then, it has evolved into a versatile component in the culinary world, being the principal ingredient in a variety of desserts and savory dishes alike.
The key to a good custard lays in its texture. It should be luxuriously smooth and creamy, with a hint of sweetness. Custard can be enjoyed on its own, but when combined with other ingredients – like oatmeal, as in our Brennan’s Oatmeal Custard – it transforms into an unforgettable treat.
Whether it’s the thick base of a sumptuous creme brûlée, the silky layer in a trifle, or the velvety center of a custard pie, the possibilities with custard are endless.

Brennan’s Oatmeal Custard: A Step-By-Step Guide

To replicate Brennan’s Oatmeal Custard in your home, you’ll need to follow a specific set of instructions to stay true to its charm. Let’s start with a list of the ingredients you will need: traditional oats, full-fat milk, some sweet sugar, a hint of vanilla extract, and your choice of spices and fruits. As for the custard, egg yolks, whole milk, sugar, and a touch of salt will create a silky-smooth custard base.
STEP: 1
The preparation of this heartwarming dessert involves cooking the oats until tender, simmering the custard ingredients on a low flame until they’ve reached a creamy consistency, then gradually merging the two components. Care should be taken while stirring to retain the lovely textural uniqueness of the oats.
Initially, you will combine oats with water and a bit of salt, cooking on medium heat until the oats are tender. Remember that patience is key; let the oats simmer and soak up the water, coaxing out their hearty flavor.
STEP: 2
Next, whisk together the egg yolks, sugar, and milk for the custard base in a separate pot. You will then gently heat this mixture, stirring continuously to prevent it from curdling. Once your custard base thickens just right, indicating that it is ready, you’ll carefully fold the cooked oats into it.
STEP: 3
At this stage, Barney often added his personal touch, which usually consisted of spices like cinnamon or nutmeg, dried fruit like raisins or currants, or a splash of Irish whiskey for an extra kick. This step is optional, of course, and you’re free to modify the recipe to suit your personal flavor preferences.
Once you’ve achieved the desired flavor profile, pour your oatmeal custard into a baking dish and bake until set, usually around 30 minutes. When done, your custard should jiggle slightly in the middle, while the edges are set and a warm, rich, beautiful golden color.
Remove your delicious Brennan’s Oatmeal Custard from the oven and let it cool. It can be served warm, or chilled for later enjoyment. If desired, garnish with sweet syrup, fresh berries or a sprinkle of powdered sugar for added sweetness.
