🥣 Step-by-Step: How to Make Warm & Gooey Apple Pie Coffee Cake

Step 1: Preheat & Prep

Preheat oven to 350°F (175°C)

Grease a 9-inch springform pan, Bundt pan, or square baking dish

Line with parchment for easy removal (if using flat pan)

✅ No sticking! Non-stick spray with flour works great.

Step 2: Make the Cake Batter

In a bowl, whisk:

Flour

Sugar

Baking powder

Baking soda

Cinnamon

Salt

In a large bowl, beat:

Butter and sugar — 4–5 minutes until light and fluffy

Add eggs one at a time, beating well after each

Mix in vanilla

Gradually add dry ingredients, alternating with sour cream

Fold in diced apples

✅ Don’t overmix — keeps cake tender.

Step 3: Layer the Swirl

Pour half the batter into the pan

Sprinkle with cinnamon-sugar mixture

Drizzle with melted butter (optional)

Top with remaining batter

✅ Swirl gently with a knife — don’t overdo it.

Step 4: Add the Crumble

In a bowl, mix:

Brown sugar

Flour

Oats

Cinnamon

Cut in cold butter with a pastry cutter or fork until crumbly

Stir in pecans (if using)

Sprinkle evenly over the top

✅ Cold butter = chunky, crisp topping.

Step 5: Bake to Golden Perfection

Bake 40–50 minutes, until:

A toothpick comes out clean

Top is golden and crisp

Edges are slightly pulling from the pan

✅ Cool 15 mins — then remove sides (if using springform).

Step 6: Serve & Savor

Slice warm — each piece should be moist, cinnamony, and packed with apple flavor

Pair with:

Hot coffee or chai tea
