A gooey butter cake inspired by almond croissants with brown butter, homemade almond filling, and toasted sliced almonds.
Brown Butter
- In a small saucepan over medium heat, melt 1/2 cup (113g) unsalted butter used for the cake batter. Cook, stirring occasionally, until the butter foams and the milk solids turn golden brown with a nutty aroma. Pour into a heatproof bowl and let cool for 10–15 minutes.(*see notes). You can also brown all the butters for the cake batter and the almond gooey layer. (**see notes)
Almond Filling
- While the brown butter is cooling, make the almond filling. In a medium bowl, beat the softened butter and powdered sugar until smooth, like a thick paste consistency.
- Add the egg yolks, almond extract, and vanilla extract and mix until combined. Fold in the almond flour and salt until a thick paste forms. Refrigerate while preparing the remaining layers.
Cake Batter
- Preheat the oven to 325°F (163°C) and line a 9x13-inch baking pan with parchment paper.
- In a large bowl, whisk together the cooled brown butter for the cake batter and granulated sugar.
- Whisk in the egg, vanilla extract, and almond extract. Combine till smooth.
- In a separate bowl, whisk together the dry ingredients, flour (***see notes), baking powder, and salt. Add the dry ingredients to the wet ingredients and mix until a thick dough forms. Press the dough evenly into the bottom of the prepared pan.
Gooey Layer
- In the bowl of a stand mixer or in a large bowl with an electric mixer, beat the cream cheese until smooth.
- Add the eggs, vanilla extract, and almond extract.
- Slowly stream in the cooled brown butter for the gooey layer.
- Add the powdered sugar and salt and mix on medium speed until smooth.
Assemble Cake and Bake
- Dollop the chilled almond filling over the base using. Evenly spread the filling and gently press slightly into the dough.
- Pour the gooey layer over the almond filling and spread gently.
- Sprinkle the sliced almonds evenly over the top.
- Bake for 35 to 45 minutes, or until the edges of the cake are golden brown and the center still has a slight jiggle.
Cool
- Let the cake cool in the pan for 10 minutes and then transfer the pan to a wire rack and cool completely before slicing. Tastes better the next day!
- Dust lightly with powdered sugar before slicing and serving.
Notes:
- Place the butter in a light colored saucepan over medium heat.
- Let it melt completely, then continue cooking. It will foam, then quiet.
- Swirl the pan occasionally. Watch for golden bits forming on the bottom.
- When it smells nutty and looks amber, remove from heat and pour into a mixing bowl.
You want golden, not burnt. Think toasted hazelnut, not coffee ash.
**Option to Brown All the Butter at Once
If preferred, brown 12 tablespoons (169g) butter in one saucepan. Divide the browned butter after cooking:
- 67% or 2/3 of the brown butter for the cake batter
- 33% or 1/3 of the cake batter for the gooey layter
Allow the portion for the batter to cool before mixing.
***How to Measure Flour Correctly
Measuring flour properly makes a big difference in how your baked recipes turn out. For best results, use a kitchen scale and measure in grams. This ensures consistency and prevents adding too much flour, which can make this cake dry or dense.
If you don’t have a scale:
- Do not scoop flour directly with the measuring cup.
- Use a spoon to gently fill the measuring cup.
- Level it off with the back of a knife.
- Do not pack the flour down.
Too much flour is one of the most common reasons baked recipes can become dry and cakey.
