These delightful Paleo Lemon Blueberry Streusel Muffins are perfect for a weekend bake, even when your pantry is looking a little bare! They offer a happy and comforting taste with freshly baked blueberries and a delicious streusel topping. Feel free to swap in any other berry or use frozen blueberries (just rinse and dry them well) for a versatile treat.
