Do you love delicious and decadent coffee cake in the morning? Chef Patrick Barclay shows how to make it in this video. Start out by combining 2 c flour, 1 tbsp baking powder, 1/4 tsp salt, 1 c sugar, 1 c butter, 1 egg, and 1 c sour cream. Mix this all together well with a wooden spoon or smooth spatula. Once mixed, spread this into a pan so all of it is even inside, then bake it at 350 degrees for around 25 minutes. Once finished, sprinkle with the delicious topping. The topping is made of 1/4 c flour, 1/2 tsp salt, 3/4 c brown sugar, 1/2 c chopped nuts, and 1/4 c butter. Knead all of these ingredients with your hand, then sprinkle over the coffee cake. You can spread it on the cake before baking if you want it baked inside. When finished, serve and enjoy with some hot coffee!
