Essential Equipment
To ensure your Recipe by Sarah turns out perfectly, you will need a 9-inch round cake pan. Lining the bottom with parchment paper is a professional secret for an easy release. You’ll also need a medium bowl for the streusel, a large mixing bowl for the cake batter, an electric mixer to achieve that light and fluffy texture, and a rubber spatula for gentle folding. These tools have been my companions through years of home cooking.
Ingredients
For the Streusel Topping:
- 6 tablespoons cold salted butter (cubed)
- 3/4 cup all-purpose flour
- 1/4 cup rolled oats (old fashioned)
- 1/2 cup granulated sugar
- Pinch of salt
For the Cake Base:
- 1 stick (1/2 cup) salted butter (at room temperature)
- 1/2 cup granulated sugar
- 2 teaspoons pure vanilla extract
- 2 large eggs
- 1 1/4 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- 1/8 teaspoon salt
- 3 tablespoons whole milk
- 3 Granny Smith apples (peeled and thinly sliced)
- Confectioners’ sugar (for dusting)

Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). Butter your 9-inch round pan and line with parchment paper.
- Make the streusel by combining flour, oats, sugar, and salt in a bowl. Rub in the cold butter with your fingertips until it looks like coarse breadcrumbs. Chill this in the fridge while you proceed.
- Cream the room-temperature butter and sugar in a large bowl on medium-high speed until light and fluffy. Add the vanilla and beat in the eggs one at a time.
- Whisk the flour, baking powder, cinnamon, and salt in a separate bowl. Fold these dry ingredients into the wet mixture using a spatula, adding the milk gradually until a smooth batter forms.
- Transfer the batter to your pan and smooth it out. Lay the sliced apples in an even layer across the top.
- Cover the apples completely with the chilled streusel topping.
- Bake for 60 to 70 minutes until the top is golden brown and crisp.
- Remove from the oven and cool slightly before removing from the pan. Dust with confectioners’ sugar just before serving.
You Must Know
Gemma Stafford recommends using salted butter for this recipe, and I couldn’t agree more. That tiny bit of extra salt provides a sophisticated depth of flavor that makes this Recipe by Sarah truly stand out. It’s a professional touch that is still easy to follow.
Storage and Reheating
This cake stays fresh in an airtight container for up to 3 days. To revive the streusel’s crunch, reheat a slice in the oven at 300°F for 5-8 minutes. You can also freeze the baked cake for up to 2 months; just ensure it is wrapped tightly in foil and plastic wrap.
Ingredient Substitutions
If you prefer a gluten-free version, a 1-to-1 baking flour blend works beautifully. For a dairy-free alternative, use a plant-based salted butter stick and oat milk. If Granny Smith apples are too tart for you, Honeycrisp apples offer a lovely sweet-tart balance.
Serving Suggestions
This is best served warm with a cup of tea. For a more decadent experience, serve it with a side of vanilla custard or a scoop of high-quality vanilla bean ice cream. In our home, we often enjoy it as a special Sunday brunch treat.
Cultural and Historical Context
The Irish Apple Cake is a “humble cake” rooted in rural traditions where ingredients were always local and seasonal. It represents the warmth of Irish hospitality—having something sweet ready just in case a neighbor drops by for a chat. For me, it bridges the gap between traditional heritage and my modern kitchen.
Seasonal Adaptations
While this is a year-round favorite, it shines in the fall when apples are at their peak. In the winter, you can add a pinch of nutmeg or cloves to the batter for extra warmth.
Perfect Occasions
This is the ultimate St. Patrick’s Day dessert. It’s also my go-to “Welcome Home” meal for my daughter returning from Agadir or a comforting treat for a rainy afternoon.

Freezer Meal Conversion
You can prepare the streusel in bulk and freeze it in bags for up to 3 months. Having it ready makes this Recipe by Sarah even more easy to follow when you’re in a hurry.
Pro Tips
To get the best texture, ensure your eggs are at room temperature before beating them into the creamed butter. This creates a more stable emulsion and a lighter, more artisanal crumb.
FAQs About Recipes
- Why is my cake dense? You might have over-mixed the flour. Fold gently with a spatula until just combined.
- Can I use other apples? Yes, but firm, tart apples like Granny Smith hold their shape best during the long bake.
- My streusel isn’t browning? Ensure your oven is fully preheated and you’re using real butter, not a spread.
- Can I make this in a square pan? Yes, but the baking time may vary slightly. Keep an eye on it after 55 minutes.
