Ingredients for almond custard seven sisters coffee cake
Twelve ingredients, three layers of magic—almond custard, fluffy cake, and buttery streusel.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | Divided for cake and streusel |
| Almond Flour 🌰 | 1 cup | Fine, not coarse |
| Baking Powder 🍞 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure, not imitation |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Unsalted Butter 🧈 | 1 ½ cups | Cold for streusel, softened for cake |
| Almond Slices 🌰 | 1 ½ cups | Toasted, slivered |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Powdered Sugar 🍚 | ½ cup | For dusting |
| Oats 🌾 | 1 cup | Old-fashioned, not quick |
| Brown Sugar 🍚 | ½ cup | Packed for streusel |
| Cinnamon 🌿 | 1 tsp | Ground, not cassia |
The almond flour is non-negotiable here—it’s what gives this cake its signature nutty depth. Bob’s Red Mill or King Arthur brands are my go-to for fine, consistent texture. If you can’t find almond flour, blend whole almonds into a fine powder yourself, but don’t skip it entirely. The almond slices? Toast them first—they add crunch and flavor that raw slices can’t match. For the butter, Plugra or Land O’Lakes work perfectly, but avoid anything with salt added. And that vanilla? Nielsen-Massey or McCormick pure extract makes all the difference.
No almond flour? Substitute with extra all-purpose flour plus 1 tbsp almond extract—it won’t be identical, but it’ll get you close. Running low on heavy cream? Full-fat coconut cream works too, though the texture will be slightly lighter. The oats in the streusel can be swapped for crushed graham crackers if you’re out, but they add a nice chewiness. For the sugar, turbinado or coconut sugar can replace brown sugar in a pinch, though the color will be different. And if you’re watching calories, reduce the butter by 2 tbsp and add 2 tbsp applesauce—no one will notice.
This cake keeps beautifully—3 days at room temperature wrapped in foil, or 1 week refrigerated in an airtight container. For longer storage, freeze the whole cake for up to 3 months. Thaw at room temperature before serving. The streusel topping stays crisp for about 2 days, so make it fresh if you’re serving it right away. And if you’re prepping ahead, assemble the cake layers the night before—just bake it in the morning. Trust me, the aroma will wake everyone up.

Step-by-step instructions for almond custard Seven Sisters coffee cake
Here's how to create layers of tender vanilla cake, rich almond custard, and crunchy streusel.
Prepare the Cake Batter
Preheat your oven to 350°F and grease a 9x13-inch baking pan. In a large bowl, whisk together the 3.5 cups All-Purpose Flour, 1 cup Almond Flour, 2 tsp Baking Powder, and 0.5 tsp Salt. Set aside.
In another bowl, beat the 1.5 cups Unsalted Butter (softened) with the 1.5 cups Granulated Sugar (reserve 0.5 cup for later) until light and fluffy, about 3-4 minutes. Add the 4 whole Large Eggs, one at a time, mixing well after each addition. Stir in the 2 tsp Vanilla Extract.
Gradually add the dry ingredients to the wet mixture, mixing just until combined. Don't overmix—you want a smooth but slightly lumpy batter. Spread half of the batter evenly into the prepared pan. This will be your first cake layer.
Make the Almond Custard Filling
In a medium saucepan, combine the 1 cup Heavy Cream, 0.5 cup Granulated Sugar (reserved earlier), 1 cup Almond Slices, and 1 tsp Cinnamon. Bring to a gentle simmer over medium heat, stirring occasionally, until the almond slices are slightly softened and the mixture thickens to a custard-like consistency, about 5-7 minutes.
Remove from heat and let cool for 10 minutes. This custard will be the star of your coffee cake—its nutty flavor and creamy texture pair perfectly with the cake layers. Spread this almond custard evenly over the first cake layer in the pan.
Add Second Cake Layer and Streusel Topping
Spread the remaining cake batter evenly over the almond custard layer. In a separate bowl, combine the 1 cup Oats, 0.5 cup Brown Sugar, 0.5 cup Almond Flour, and 1 tsp Cinnamon for the streusel topping. Cut in the 0.5 cup cold Unsalted Butter (using a pastry cutter or fork) until the mixture resembles coarse crumbs.
Sprinkle the streusel topping evenly over the second cake layer. The streusel should cover the entire surface, leaving some gaps for the custard to peek through when baked. This is where the magic happens—the streusel will become golden and crunchy while the layers stay tender.
Bake to Golden Perfection
Bake the coffee cake in the preheated oven for 45-50 minutes, or until a toothpick inserted in the center comes out clean. The edges should be golden brown, and the top should be beautifully streusel-covered with a few caramelized spots.
Real talk: Don't open the oven during the first 30 minutes of baking. The steam needs time to build for that perfect rise. When you do check, you'll see the streusel turning a beautiful golden brown—that's your cue it's almost done. Let the cake cool in the pan for 15 minutes before transferring to a wire rack.
Dust and Serve
Once cooled, dust the top generously with the 0.5 cup Powdered Sugar using a fine-mesh sieve. This adds that final touch of sweetness and makes the coffee cake look like it came from a bakery. Serve warm with a cup of coffee or tea for the ultimate comfort experience.
The cake should have layers of tender vanilla cake separated by rich almond custard, all topped with a crunchy, caramelized streusel. Each bite should deliver a perfect balance of textures—soft cake, creamy custard, and nutty crunch. Cut into squares and enjoy!
Pro Tips For Making Almond Custard Seven Sisters Coffee Cake
- WHISK ALMOND FLOUR FIRST: I learned this the hard way—almond flour clumps like a stubborn guest who won’t leave. Whisk it with the dry ingredients before adding wet ones, or you’ll end up with lumps that turn into dry pockets in your cake. (Yes, even if you’re impatient like me.)
- MEASURE SUGAR BY WEIGHT: Granulated sugar in this recipe isn’t just flavor—it’s structure. Volume measurements (like "1 cup") vary wildly by packing. Use a kitchen scale for 200g (about 1 cup packed) to guarantee a tender crumb, not a brick.
- DON’T OVERMIX THE BATTER: After folding in the custard mixture, stop mixing the second the flour disappears. One more stir = tough cake. The almond flour and baking powder need just enough air to rise, not a workout. (I’ve seen this cake go from light to dense in 30 seconds of overmixing.)
- BAKE UNTIL 205°F INTERNAL: The Seven Sisters version hides a custard center that needs time to set. A toothpick check is useful, but the real test is the internal temp hitting 205°F (96°C)—that’s when the almond custard turns silky, not gummy. (Your future self will thank you for not rushing this.)
Troubleshooting this dish
Cake Too Dense
If your cake turns out dense instead of tender, overmixing is usually the culprit. Mix the batter just until combined—stop as soon as the flour disappears. Another common issue is using cold eggs or butter.
Always use room-temperature eggs and softened butter (about 65°F) for a lighter texture. I’ve also found that sifting the dry ingredients first helps prevent dense layers. 💡
Custard Too Thin
The almond custard should thicken slightly as it cools, but if it’s still runny after baking, you likely didn’t simmer it long enough. Cook the custard until it reaches a gentle boil and thickens to a pudding-like consistency—about 7-10 minutes.
For extra insurance, whisk in 1 tsp cornstarch mixed with 1 tbsp cold water at the end. This trick saves custards every time.
Streusel Not Crunchy
If your streusel turns out mushy instead of crisp, the butter might have melted too quickly during baking. Use cold butter (cut into small cubes) and avoid overmixing the streusel—just combine until it resembles coarse crumbs.
Another fix? Bake the cake at 350°F for the full 45-50 minutes without opening the oven door early. The streusel needs time to crisp up.
Layers Separating
If the almond custard or cake layers pull apart when cutting, your cake likely didn’t bake long enough. The center should be set but still slightly springy to the touch. For extra stability, chill the cake for 1 hour in the fridge before slicing.
This helps the layers hold together better. Also, ensure your custard is fully cooled before spreading—hot custard can melt the bottom cake layer.
Burnt Topping
A burnt streusel topping usually means the oven was too hot or the cake baked too long. Stick to 350°F and check for doneness at 40 minutes—the streusel should be golden, not dark brown.
If your oven runs hot, reduce the temperature to 325°F and add 5-10 minutes to the bake time. A light spray of water on the streusel before baking can also help prevent over-browning.
Dry Cake Texture
Dry cake often results from overbaking or using too much flour. Pull the cake out when a toothpick comes out with a few moist crumbs—not completely clean.
To prevent dryness, brush the cake layers with 2 tbsp heavy cream or simple syrup (equal parts sugar and water, heated) before adding the custard. This adds moisture and keeps the cake tender. 💫

Frequently asked questions
What makes this almond custard coffee cake different from regular coffee cake?
This version features a luxurious almond custard layer between tender vanilla cake layers, plus a buttery streusel topping. The almond custard adds a creamy, nutty depth that transforms it from ordinary coffee cake to something special. The streusel provides that perfect crunchy contrast—unlike traditional coffee cakes that often have just one layer or a simple crumb topping.
Can I make this coffee cake without almond flour?
Yes! Substitute with extra all-purpose flour plus 1 tbsp almond extract for flavor. The texture won't be identical, but it'll still taste delicious. For the almond slices in the custard, you can use toasted sliced almonds or even chopped pecans if you're out of almonds. The nutty flavor remains, just with a slightly different texture.
How do I store leftovers to keep them fresh?
Wrap the cake tightly in plastic wrap or foil and store at room temperature for 2-3 days. For longer storage, refrigerate for up to 1 week or freeze for 3 months. Thaw overnight in the fridge before serving. The streusel stays crisp best when stored this way, while the custard remains creamy.
Can I bake this in a different pan size?
This recipe is designed for a 9x13-inch pan, but you can adapt it. For an 8x8-inch pan, reduce all ingredients by about 25%—just bake at 375°F for 35-40 minutes. If using a 9x11-inch pan, reduce ingredients by 15% and bake at 350°F for 40-45 minutes. Always adjust baking time based on your specific oven.
What's the best way to serve this coffee cake?
Serve warm with a cup of freshly brewed coffee or tea for the ultimate experience. For extra indulgence, add a scoop of vanilla ice cream or a dollop of whipped cream. Dusting with powdered sugar right before serving adds that bakery-fresh touch. It's perfect for brunch, dessert, or even as a special treat with morning coffee!
