This frangipane coffee cake is packed with a rich almond filling, spiced streusel, and a tender crumb that feels like dessert dressed up as breakfast. Whether it's for a brunch or a special holiday, this is the coffee cake to make.
Preheat the oven to 350°F. Grease a 9-inch spring-form pan with nonstick baking spray and set it aside.
Make the frangipane filling: In the bowl of an electric mixer, beat the almond paste on low until it is broken into pieces. Add the eggs and beat on medium until smooth. Add the almond extract, butter, and baking powder. Mix until it is combined. Place the mixture in a separate bowl and set it aside.
7 oz tube almond paste, 2 large eggs, ½ tsp almond extract, 12 tbsp (1 ½ sticks) unsalted butter, 1 ½ tsp baking powder
Make the streusel: In a bowl, combine the light brown sugar, flour, almonds, cinnamon, cardamom, and salt. Mix to combine and add the pieces of butter. Use hands to work the butter into the mixture until it resembles crumbly, wet sand. Set the bowl aside.
¾ cup light brown sugar, 1 ¼ cups all-purpose flour, 1 cup sliced almonds, 1 ½ tsp ground cinnamon, ¾ tsp ground cardamom, ¼ tsp kosher salt, 8 tbsp (1 stick) unsalted butter
Make the cake: In the bowl of the electric mixer, cream the butter and sugar until it is light and fluffy, 3 minutes. With the mixer on low, add the eggs one at a time, allowing each to incorporate before adding the next. Add the Greek yogurt and vanilla extract and mix. Add the flour, salt, baking powder, and baking soda. Mix until the batter is combined with no dry streaks remaining, 1-2 minutes.
12 tbsp (1 ½ sticks) unsalted butter, 1 cup granulated sugar, 3 large eggs, ¾ cup Greek yogurt, 1 ½ tsp vanilla extract, 2 cups all-purpose flour, 1 tsp kosher salt, 1 tsp baking powder, 1 tsp baking soda
Assemble: Pour half of the batter into the prepared pan and spread to an even layer. Crumble the frangipane over the first layer of batter evenly. Top with the remaining cake batter, spread it to an even layer, and sprinkle with the streusel.
Bake in the preheated 350°F oven until the cake is golden brown and is set in the middle, 60-70 minutes. Remove from the oven and cool in the pan for 45 minutes. Remove from the pan and cool fully. Before serving, dust with powdered sugar.
