Rhubarb and Custard Crumble Muffins: A classic combo rolled up into a delicious batch of muffins. These are a great bake to make ahead for a week of breakfasts or for a fancy brunch spread. I create a simple custard drizzle with instant custard but feel free to use fresh if preferred (or omit). Use any leftover custard to spread over the muffins, ideally whilst still warm!
As with all my muffin recipes, this is kept simple and no electric mixer is called for. In fact, these are my tips for MAXIUM MOISTURE. Stir as little as possible, and only with a wooden spoon. Use multiple liquid/fat ingredients (as you’ll see in the recipe). Coat your rhubarb in sugar before stirring into the mixture.
I am a huge fan of muffins as a gentle weekend bake. They are super easy to make but always so impressive to other people. These are such a great treat, and can easily be frozen. This recipe makes about 6 large muffins. If using small muffin tins/liners, it may make closer to 8. Feel free to double the recipe if hoping to take them into work or feeding a crowd!
