Ingredient Notes & Substitutions
Almond Flour
The almond flour adds a rich, nutty flavor and lighter texture compared to traditional oat streusel. It creates a more refined topping that pairs beautifully with the apples.
Substitutions: You can use 1/2 cup rolled oats instead of almond flour for a more traditional streusel, or a mix of 1/4 cup each of almond flour and all-purpose flour for a different texture.
These apples hold their shape during baking and provide the perfect balance of tartness that complements the sweetness of the filling. The acidity also helps prevent browning.
Substitutions: You can use Honeycrisp or Fuji apples for a sweeter option, or a mix of Granny Smith and Honeycrisp for balanced flavor.
Substitutions: You can use all brown sugar if you prefer a deeper flavor, or all granulated sugar for a lighter filling.
Using cold butter in the streusel ensures it stays in small pieces, creating a crumbly texture. This is crucial for achieving that signature streusel crunch.
Substitutions: If you forget to chill the butter, you can still use it but it will create a denser topping. For best results, always use cold butter.
Use a mandoline or sharp knife to slice apples evenly. Uniform slicing ensures even baking. Toss apples immediately with the sugar mixture to prevent browning.
The streusel should look like coarse sand with some larger chunks. If it's too dry, add a teaspoon of cold water. If too wet, add a bit more flour or oats.
Prepare the apple filling and streusel separately up to 24 hours ahead. Store in airtight containers in the refrigerator. Assemble just before baking.
Add a teaspoon of vanilla extract to the streusel for extra depth of flavor. A pinch of sea salt on top before baking enhances the sweetness.
Variations & Customizations
Cinnamon Sugar Streusel
Omit the almond flour and use 1 cup rolled oats instead. Add an extra teaspoon of cinnamon for a more traditional streusel topping.
Chocolate Drizzle
After baking, drizzle with a simple chocolate sauce made from melted dark chocolate, a bit of heavy cream, and a touch of salt for a decadent twist.
Spiced Apple Crisp
Add 1/2 teaspoon of pumpkin pie spice to the apple filling for a warm, spiced flavor that's perfect for fall.
VVhanberry Compote
Add a layer of reduced cranberry sauce between the apples and streusel for a tart contrast to the sweet apples.
Serving Suggestions & Pairings
🍽️ Best Served With:
- Vanilla ice cream for a classic contrast of warm and cold
- Caramel sauce drizzled over the top for extra richness
- Whipped cream for a light and elegant finishing touch
🍷 Drink Pairings:
Pair with a buttery Chardonnay or a spiced chai tea to complement the warm spices and caramel flavors.

Troubleshooting & Common Questions
Q: Why is my streusel too dry?
A: If your streusel is too dry, it might be because the butter was too warm or you overmixed it. Ensure the butter is cold and handle the mixture gently.
Q: Can I use a different pan size?
A: This recipe is specifically designed for a 9x13-inch pan. Using a different size may affect baking time and texture.
Q: How do I prevent the apples from becoming too soft?
A: Use Granny Smith apples which hold their shape better. Don't overbake - the apples should be tender but not mushy.
Q: Can I make this gluten-free?
A: Yes! Use a certified gluten-free all-purpose flour blend for the apples. The streusel is naturally gluten-free if using almond flour and oats labeled gluten-free.
