Sourdough Pecan Coffee Cake

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Grease and lightly flour an 8x8-inch cake pan.

2 . Stage

Cut cold butter into small pieces with a knife and place in a medium mixing bowl. Add brown sugar, flour, cinnamon, and salt. Use a pastry knife or 2 forks to cut butter into dry ingredients until large crumbs form. Set streusel aside.

3 . Stage

Combine flour, cinnamon, baking soda, and salt in a medium bowl.

4 . Stage

Beat sugar and butter together in a large bowl with an electric mixer until creamy and fluffy. Add egg and mix for 1 minute. Add sourdough discard and dry ingredients; mix until just combined. Pour batter into the prepared pan and sprinkle streusel on top, followed by the pecan pieces.

5 . Stage

Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 35 minutes. Place pan on a wire rack to cool for 10 minutes.

6 . Stage

Stir confectioners' sugar, milk, vanilla, and salt together to make the glaze. Add more sugar to make a thicker glaze, or more milk to make a thinner glaze.

7 . Stage

Pour the glaze into a resealable plastic bag and seal. Snip a tiny piece, about 1/8 of an inch, off one of the bottom corners. Hold bag over the cake and squeeze the glaze through the tiny opening, moving your hand across the top, drizzling glaze as you go. Cut cake into 9 pieces and serve.
