The streusel topping is what sets these muffins apart: sweet, buttery, and full of warm spice.

How simple are they to make? Very. Prepare the streusel, mix the muffin batter, fold in the apples, top with streusel, and bake. The steps are straightforward and ideal for home bakers of any level.

What’s in Apple Coffee Cake Muffins?

• Old-fashioned oats: Adds texture and a hearty crunch to the streusel.
• Walnuts: Provide a toasty, nutty contrast that pairs well with apples and cinnamon.
• Cinnamon: A fall baking staple that brings warmth and depth.
• Apples: Diced apples add moisture and fresh apple flavor; Honeycrisp is recommended for sweetness and crunch.
• Applesauce: Use unsweetened applesauce to add moisture without extra sugar.
• Almond milk (or other milk): Non-dairy or dairy milk both work; almond milk adds a mild, slightly nutty note.

Kitchen Tools Needed

• Electric mixer: Makes creaming the butter and sugar quick and ensures a smooth batter.
• Muffin tin: Standard 12-cup muffin tin; paper liners are optional but recommended for easy removal.

Substitutions & Variations

Nuts: Swap walnuts for pecans, hazelnuts, almonds, or cashews depending on preference or what you have on hand.

Spices: For more complexity, add a pinch of nutmeg or ground ginger. Pumpkin spice or chai spice blends also complement the apples and cinnamon well.

Apples: Honeycrisp works beautifully, but feel free to use Gala, Fuji, or even a firmer apple like Mutsu. Granny Smith will add tartness if you prefer less sweetness.

Milk: Any dairy or plant-based milk will work. Flavored milks can add an extra layer of taste.

Topping: The streusel is delightful but optional. Alternatives include a simple glaze, a maple-brown-sugar frosting, or a sprinkle of chopped nuts or seeds.

Prep: 20 minutes   Cook: 18 minutes   Total: 38 minutes   Servings: 12

Ingredients

Streusel Topping

• ¾ cup old-fashioned oats
• ¼ cup all-purpose flour
• ⅓ cup light brown sugar, packed
• ⅓ cup chopped walnuts
• 5 tablespoons unsalted butter, cold
• ¼ teaspoon vanilla extract

Dry Muffin Ingredients

• 1¾ cups all-purpose flour
• 1 teaspoon baking powder
• ½ teaspoon salt
• 1 teaspoon ground cinnamon
• 1 cup diced apples (Honeycrisp recommended)

Wet Muffin Ingredients

• ⅓ cup light brown sugar, packed
• 1 teaspoon vanilla extract
• 3 tablespoons unsalted butter, melted
• ½ cup unsweetened applesauce
• 2 large eggs
• ½ cup almond milk (or other milk)

Instructions

1. Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
2. Make the streusel: Combine oats, flour, brown sugar, chopped walnuts, cold butter, and vanilla in a bowl. Use a spoon or your fingers to cut the butter into the dry ingredients until coarse crumbs form. Set aside.
3. Whisk together the flour, baking powder, salt, and cinnamon in a separate bowl and set aside.
4. In another bowl, use an electric mixer to cream the brown sugar, vanilla, and melted butter until light and slightly fluffy. Stir in the applesauce, then add the eggs and mix until combined. Add ½ cup milk and stir.
5. Fold the dry ingredients into the wet mixture until just combined. Gently fold in the diced apples. If the batter is very thick, add milk 1 tablespoon at a time until the batter reaches a scoopable, slightly thick but pourable consistency.
6. Spoon batter into the prepared muffin cups, filling each about ¾ full. Top each with about 1 to 1½ tablespoons of streusel, gently pressing it into the batter. Lightly spray the streusel with a bit of cooking spray if you want a deeper golden finish.
7. Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean and the muffins are golden on top. Cool in the tin for a few minutes, then transfer to a wire rack to cool completely.

Tips & Notes

• Both white whole wheat and all-purpose flour work; whole wheat will yield a slightly darker, denser muffin while all-purpose produces a lighter, fluffier texture.
• Cold butter in the streusel creates chunkier crumbs and better texture.
• There may be extra streusel—save it for topping a few extra muffins or a bowl of yogurt.
• If you prefer to skip the streusel, the muffins are still delicious on their own or with a simple glaze.
