A melt-in-your-mouth single layer blueberry cake filled with juicy sweet blueberries and a hint of amaretto that's perfect for breakfast, brunch, snacking or dessert.Serves 9 - 12
Spray or grease a square 8-inch baking pan. You can line it with parchment and spray that also if you like.
If you’re making your own buttermilk, do that now. See notes.
Toss the blueberries with the 2 tablespoons of flour gently with a fork until the blueberries are coated. Set aside.
In a bowl, whisk the remaining flour, baking powder and salt. Set aside
Beat the butter and 1 cup of sugar on medium high speed for 3 minutes until lightened in color. It's important to beat for at least 3 minutes to get the proper texture.
Add the eggs, and beat for another 2 minutes. The batter should be light in color and fluffy. Scrape down the bowl.
Add half of the flour mixture and beat just until it is combined.
Add the amaretto and all of the buttermilk and beat just until it is mixed in. It will look curdled but that’s ok.
Add remaining flour mixture and beat for 30 seconds until it’s combined.
Using a spatula, fold in the blueberries and the remaining flour in the bowl. You can reserve a few of the blueberries to sprinkle on top before sprinkling on the sugar.
Transfer the batter into the prepared pan. If you reserved a few blueberries, scatter them on top then sprinkle the top evenly with the tablespoon of sugar. Bake for 40 - 45 minutes. Depending on the oven, you may have to bake as long as 50 minutes. Check with a toothpick for doneness. I’ve baked this using 2 different ovens and found the time to vary by as much as 10 minutes.
Place the cake on a cooling rack to cool. Serve and enjoy.
Notes
Make your own buttermilk by adding 1 ½ teaspoons of lemon juice to a measuring cup then add enough milk to make ½ cup.You can use frozen blueberries. Just toss with flour and continue with the recipe. Do not thaw. Toss blueberries with the flour just before adding.I use amaretto to give a nice flavor. You can substitute with vanilla or use ½ teaspoon of lemon or almond extract.
