Third, in a medium bowl combine streusel ingredients: flour, sugars, cinnamon, almonds and salt. Slowly add the melted butter until crumbs resemble course sand. Set aside.

Mix on medium speed until aerated, light and fluffy. Add 1/4 cup walnut oil and mix. Then, add eggs one at a time mixing in between. Then lastly, add greek yogurt and vanilla extract mixing until just combined. Be sure not to over-mix!
3. To the wet ingredients, slowly add the bowl of dry ingredients and gently mix until just combined. Don’t overdo it.
4. ‍Assembly: Fill each muffin tin halfway full with muffin batter. Then, spoon and spread the cinnamon swirl over the batter. Then, fill the rest of the tin with muffin cup until it’s 3/4 full. Lastly, top each cup with streusel topping, gently pressing to make sure it adheres to the batter.
5. ‍Bake: Place in oven for 5 minutes at current temperature. Then, without opening the oven, lower temperature to 375 for 12-15 minutes to finish baking. When tops are golden brown and toothpick comes out clean, remove from oven. Allow to cool for about 10 minutes.
6. ‍Glaze: While cooling, combine glaze ingredients in a small bowl and whisk to combine until reaching desired consistency.
7. ‍Eat:  Drizzle muffins with vanilla glaze and enjoy! Store remaining in airtight container of up to two days.
