The Tim Hortons Fruit Explosion Muffin is a super tasty treat that combines the goodness of a moist vanilla cake muffin with bursts of fruity flavor. While the exact creation date isn’t widely documented, these muffins have become a beloved staple at Tim Hortons. Founded in 1964, Tim Hortons is an iconic Canadian restaurant known for its quality coffee, freshly baked goods, great fast-food and hockey roots. Great tasting coffee (the ‘double double’) is at the core of their identity.
If you’re a fan of Tim Hortons’ Fruit Explosion Muffins, you’ll love these homemade versions. Another reason to try a copycat version is the calorie count. From what I understand, the Tim Hortons version comes in at 360 calories per muffin whereas this recipe trims it down to a ‘healthy’ 166 calories for the medium size and 331 for large ones.
The combination of sweet and tart flavors from the fruit creates a wonderful balance with the natural sweetness of the berries complementing the muffin base. Sour cream is a secret ingredient that makes these muffins extra moist. They’re soft, cakey, tender and in the center, have a little fruity surprise of blueberry jam.
The options for making this treat are endless—swap out the berries or try different fruit fillings. Whether for breakfast or a snack, these muffins are a burst of fruity goodness! Another bonus is that these muffins freeze beautifully, making them convenient for busy mornings.
