My youngest daughter had her first lemon poppy seed muffins at a friend’s house. She came home and told me it was the best-tasting muffin she’d ever had. So, of course, rather than asking for the recipe, I set out to create a version of a recipe for lemon poppy seed muffins with crumb topping my own! It took a couple of tries, but I finally got it, and it is one of our family’s muffin recipes. This
lemon poppy seeds muffins recipe is perfect for a sweet afternoon treat, dessert or a weekend brunch.
What is the Secret to Bakery Style Muffins
Don’t overmix – Add dry ingredients just until combined, or your muffins will have a tough texture
Make the batter in advance – keep it in the refrigerator for an hour. The longer, the better.
Place the batter into every other muffin cup – allow them to rise and also circulate more heat around them, put 1/2 inch of water into the empty ones.
Fill the muffin batter to the top
Bake at a high heat for the first 5 minutes and then lower the temperature
