Lemon Poppy Seed Muffins

These vanilla muffins are a deceptively simple combination of flour, butter, sugar, and eggs along with a generous amount of vanilla extract. (For a richer, more decadent vanilla flavour, try using 1/4 teaspoon of vanilla bean paste.) You might not think much of them at first glance, but the results are tender, moist, and lightly sweet muffins that need little to no embellishment.
