Equipment
- 2 standard muffin tins
- Paper muffin liners or nonstick spray
- Mixing bowls (1 large, 1 medium)
- Fork or potato masher
- Whisk or spoon
- Measuring Cups and Spoons
- 3–4 Tablespoon cookie or ice cream scoop
Ingredients
Wet Ingredients:
- 3 medium bananas about 1¼ cups mashed
- 2 large eggs
- ½ cup melted butter
- ½ cup milk
- ½ cup plain Greek yogurt or sour cream
- 2 teaspoons vanilla extract
- ½ cup brown sugar
Dry Ingredients:
- 2 cups all-purpose flour
- 1½ cups old-fashioned oats
- 1 tablespoon baking powder
- ½ teaspoon salt
- 8 ounces blackberries about 2 heaping cups
Instructions
- Preheat Oven and Prepare Tins: Begin by preheating your oven to 375°F (190°C) to ensure it reaches the perfect temperature for even baking. Line two standard muffin tins with paper liners or lightly spray with nonstick spray to prevent sticking and make removal effortless. Proper preparation ensures muffins bake evenly and come out with a beautiful golden-brown top.
- Mash the Bananas: Peel three medium bananas and place them in a medium mixing bowl. Use a fork, potato masher, or immersion blender to mash them into a smooth puree, aiming for about 1¼ cups. The bananas should be creamy with no large chunks, providing natural sweetness and moisture to the muffins.
- Combine Wet Ingredients: In a large mixing bowl, whisk together the mashed bananas, two large eggs, ½ cup melted butter, ½ cup milk, ½ cup Greek yogurt (or sour cream), and two teaspoons of vanilla extract. Whisk for 1–2 minutes until smooth and slightly fluffy, creating a uniform base that ensures tender, soft muffins.
- Add Brown Sugar to Wet Mixture: Sprinkle ½ cup brown sugar over the wet ingredients and gently whisk until mostly dissolved. This adds subtle caramel-like sweetness, complementing the bananas and blackberries without overpowering the muffins.
- Prepare Dry Ingredients: In a separate bowl, combine 2 cups all-purpose flour, 1½ cups old-fashioned oats, 1 tablespoon baking powder, and ½ teaspoon salt. Stir until evenly mixed to ensure the leavening and salt are distributed for balanced flavor and proper rising.
- Incorporate Dry Ingredients into Wet: Gradually add the dry ingredients to the wet banana mixture. Use a spatula or large spoon to fold gently, stirring just until no pockets of flour remain. Avoid overmixing, as this can make muffins dense and tough rather than soft and airy.
- Prepare Blackberries: Slice 8 ounces of blackberries into halves or thirds depending on size. Gently fold them into the batter to distribute evenly. This prevents the muffins from turning purple or watery while ensuring each muffin has juicy bursts of flavor.
- Portion Batter into Muffin Tins: Use a 3–4 tablespoon scoop (about ⅓ cup) to evenly distribute batter into the prepared muffin liners. Fill each cup nearly to the top, leaving a little space for rising. Smooth tops gently with a spoon if needed.
- Bake the Muffins: Place muffin tins in the preheated oven and bake for 20–22 minutes. To test doneness, insert a toothpick into the center of a muffin; it should come out clean or with a few crumbs. Muffins should be golden brown and spring back lightly when touched.
- Cool and Serve: Allow muffins to cool in the tins for 5–10 minutes, then transfer to a wire rack to cool completely. This prevents soggy bottoms and ensures perfect texture. Serve warm, at room temperature, or freeze for later. Pair with nut butter, honey, or enjoy as-is for a wholesome snack.
Notes
- Use ripe bananas for maximum natural sweetness and moisture. Overly green bananas will make the muffins less flavorful and slightly denser.
- When measuring oats and flour, lightly spoon them into the measuring cup and level with a knife to avoid dry or dense muffins.
- For evenly distributed berries, gently fold them into the batter instead of stirring vigorously; this prevents the muffins from turning purple or watery.
- Adjust sweetness based on preference—reducing brown sugar slightly can make the muffins lighter, while adding a touch more enhances the caramel notes.
- If using frozen blackberries, thaw completely and pat dry to prevent excess liquid in the batter, which can affect texture and baking time.
