1-First Steps: Mixing and Cooking In a saucepan, whisk together the milk and flour until smooth to avoid any lumps right from the start. This step is crucial as it sets the base for that perfect texture. Cook the mixture over medium heat, stirring constantly until it thickens like pudding, which takes about 5-7 minutes.

2-Cooling and Beating: Once thickened, remove it from the heat and let it cool fully to room temperature, or pop it in the fridge to speed things up. In a separate bowl, beat the softened butter until it’s creamy and light. Gradually mix in the sugar, keeping the beater going to blend it well.

3-Combining and Finishing: Slowly add the cooled mixture to the butter, beating continuously to create a fluffy result. For the best outcome, use this frosting right away on your cakes or store it for later. If you’re adapting for diets, swap in plant-based milks or gluten-free flours in that first step and watch it come together beautifully.
