Muffins are my jam. I always made a batch for my sons’ playdates. These peanut butter banana chocolate chip muffins are made with whole wheat pastry flour, which is hearty but creates a more delicate crumb than regular whole wheat flour. These muffins are tender and not too sweet. The combination of peanut butter to banana in the recipe does not have one flavor over-power the other. As for the espresso powder, that doesn’t make the muffin taste like coffee; it brings out the chocolate flavor in the chocolate chips and gives the muffins a slightly nutty, roasted flavor. It’s a must have in this recipe! My favorite espresso powder is from King Arthur.
